 Preface

Note
The Equipment Manual describes a desired state which, if maintained, ensures the required
level of operational reliability and compliance with EMC limit values.
Should there be any deviation from the requirements in the Equipment Manual, appropriate
actions (e.g. measurements) must be taken to check/prove that the required level of
operational reliability and compliance with EMC limit values are ensured.

ESD information

CAUTION
Electrostatic sensitive devices (ESD) are single components, integrated circuits or devices
that can be damaged by electrostatic fields or electrostatic discharges.
Regulations for handling ESD components:
When handling components, make sure that personnel, workplaces, and packaging are
well grounded.
Personnel may only come into contact with electronic components, if
• They are grounded with an ESD wrist band, or
• They are in ESD areas with conductive flooring, ESD shoes or ESD grounding straps.
Electronic boards should only be touched if absolutely necessary. They must only be
handled on the front panel or, in the case of printed circuit boards, at the edge.
Electronic boards must not come into contact with plastics or items of clothing containing
synthetic fibers.
Boards must only be placed on conductive surfaces (work surfaces with ESD surface,
conductive ESD foam, ESD packing bag, ESD transport container).
Electronic boards may not be placed near display units, monitors, or televisions (minimum
distance from the screen > 10 cm).
Measurements must only be taken on boards when the measuring instrument is grounded
(via protective conductors, for example) or the measuring probe is briefly discharged before
measurements are taken with an isolated measuring device (for example, touching a bare
metal housing).

Safety information

DANGER
Commissioning is absolutely prohibited until it has been completely ensured that the
machine in which the components described here are to be installed is in full compliance
with the provisions of the EC Machinery Directive.
Only appropriately qualified personnel may install, commission, and maintain SINAMICS S
devices.
The personnel must take into account the information provided in the technical customer
documentation for the product, and be familiar with and observe the specified danger and
warning notices.
Operational electrical equipment and motors have parts and components which are at
hazardous voltage levels, that if touched, can result in severe bodily injury or death.
All work on the electrical system must be carried out when the system has been
disconnected from the power supply.
In combination with the drive system, the motors are generally approved for operation on
TN and TT systems with grounded neutral and on IT systems.
In operation on IT systems, the occurrence of a first fault between an active part and
ground must be signaled by a monitoring device. In accordance with IEC 60364-4-41 it is
recommended that the first fault should be eliminated as quickly as practically possible.
In networks with a grounded external conductor, an isolating transformer with grounded
neutral (secondary side) must be connected between the supply and the drive system to
protect the motor insulation from excessive stress. The majority of TT systems have a
grounded external conductor, so in this case an isolating transformer must be used.

DANGER
Correct and safe operation of SINAMICS S drive units assumes correct transportation in
the transportation packaging, correct long-term storage in the transport packaging, setup
and installation, as well as careful operation and maintenance.
The details in the Catalogs and proposals also apply to the design of special equipment
versions.
In addition to the danger and warning information provided in the technical customer
documentation, the applicable national, local, and system-specific regulations and
requirements must be taken into account.
To ensure compliance with EN 61800-5-1 and UL 508, only safety extra-low voltages from
the electronics modules may be connected to connections and terminals.

 Preface

DANGER
Using protection against direct contact via DVC A (PELV) is only permissible in areas with
equipotential bonding and in dry rooms indoors. If these conditions are not fulfilled, then
other protective measures against electric shock must be used (e.g. protection using
protective impedances or limited voltage or using protective classes I and II).

DANGER
Electrical, magnetic and electromagnetic fields (EMF) that occur during operation can pose
a danger to persons who are present in the direct vicinity of the product - especially
persons with pacemakers, implants, or similar devices.
The relevant directives and standards must be observed by the machine/plant operators
and people present in the vicinity of the product. These are, for example, EMF Directive
2004/40/EEC and standards EN 12198-1 to -3 in the European Economic Area (EEA) and,
in Germany, the accident prevention regulation BGV 11 and the associated rule BGR 11
"Electromagnetic fields" from the German Employer's Liability Insurance Association.
These state that a hazard analysis must drawn up for every workplace, from which
measures for reducing dangers and their impact on persons are derived and applied, and
exposure and danger zones are defined and observed.
The relevant safety notes in each chapter must be observed.

DANGER
As part of routine tests, SINAMICS S components will undergo a voltage test in accordance
with EN 61800-5-1. Before the voltage test is performed on the electrical equipment of
machines acc. to EN 60204-1, Section 18.4, all connectors of SINAMICS S equipment must
be disconnected/unplugged to prevent the equipment from being damaged.
Motors should be connected up in accordance with the circuit diagram supplied with the
motor (refer to the connection examples for Power Modules). They must not be connected
directly to the three-phase supply because this will damage them.

WARNING
Operating the equipment in the immediate vicinity (< 1.8 m) of cell phones with a
transmitter power of > 1 W may cause the equipment to malfunction.

1.3 DRIVE-CLiQ interface for CU305

1.3 DRIVE-CLiQ interface for CU305

The CU305 has a DRIVE-CLiQ interface. You may connect exactly one of the following
components to this interface:
● SMI motor
● 1 encoder of type SMC10, SMC20, SMC30, SME20 or SME25
Further components or connections to the DRIVE-CLiQ interface are not permitted and lead
to errors in the drive system.

Note
If you want to use an SSI encoder with incremental signals, you will need to connect it to the
CU305 via an SMC30.

1.4 Notes on the commissioning of a 2-pole resolver as absolute

encoder

Description
You can use 2-pole (1 pole pair) resolvers as singleturn absolute encoders. The absolute
encoder position actual value is provided in Gn_XIST2 (r0483[x]).
Actual position value format
The factory setting for the fine resolution of Gn_XIST1 differs from the fine resolution in
Gn_XIST2 (p0418 = 11, p0419 = 9). This may cause a slight displacement of the encoder
position after switching the drive unit off/on.
Therefore, when using a 2-pole resolver as an absolute encoder, we recommend that the
fine resolution for Gn_XIST1 (p0418) is set the same as the fine resolution for Gn_XIST2
(p0419), e.g. p0418 = p0419 =11.
2-pole resolvers are automatically entered in the PROFIdrive profile (r0979) as singleturn
absolute encoders.
Position tracking
You can also activate position tracking for a 2-pole resolver. Please note, however, that the
resolver may not be moved more than half an encoder revolution (pole width) when switched
off. The activation and configuration of the position tracking is described in the chapter
"Position tracking".
EPOS - absolute encoder adjustment
If the 2-pole resolver is used as an absolute encoder for basic positioning (EPOS), the
absolute encoder adjustment must be performed:
● via STARTER (Basic positioner → Referencing) or
● via the expert list.
To do this, set reference point coordinate p2599 to the value corresponding to the
mechanical system and request the adjustment with p2507 = 2.
You will then need to back up the data from RAM to ROM.

1.5 Temperature sensors for SINAMICS components

SMC30
In addition to temperature evaluation via terminal X531 (temperature channel 1), this module
also has temperature evaluation at SUB-D socket X520 (temperature channel 2).
At the default setting (p0600 = 1 "Temperature via encoder 1" and p0601 = 20 "KTY") the
temperature is analyzed using the first temperature channel. The temperature sensor is
connected to terminal X531 on the SMC30. The temperature is shown via r0035.
The parameterization of the motor temperature evaluation via the sub D socket X520 must
be performed in the expert list as follows:
● p0600[0..n]: Selection of the encoder (1 or 2) to which the SMC30, that is used for the
temperature evaluation, is assigned (n = motor data set).
● p0601[0..n] = 10 (evaluation via several temperature channels), n = motor data set.
● p4601[0..n]: Select the temperature sensor type for temperature channel 2 (depends on
encoder data set n, not motor data set).
For multiple temperature channels (use of temperature channels 1 and 2 on SMC30),
parameter r0035 shows the maximum temperature.
Example:
A KTY temperature sensor is connected at SUB-D socket X520 on the SMC30 of encoder 1.
This is parameterized via:
● p0600[0..n] = 1 / p0601[0..n] = 10 / p4601[0..n] = 20
Both temperature channels (X520 and X531) can be used at the same time. In addition to
the above parameterization, the sensor type of the temperature sensor connected at terminal
X531 must be entered in p4600[0..n]. The maximum value is then generated for the motor
temperature and displayed in r0035.
CU305
One temperature sensor can also be connected to this module via terminal X133 or via SUB-
D socket X23.
It is not possible to use both temperature channels (X23 and X133) at the same time. Both
channels are connected with each other. The sensors would be connected in parallel and the
temperature display would show the wrong value. As such, only one temperature sensor
may be connected to the CU305.
Use the Motor temperature STARTER screen (\Signals and monitoring\Motor temperature)
to determine whether motor temperature evaluation is performed via the CU305 connections.

Faults and alarms

F07011 drive: Motor overtemperature
KTY sensor:
The motor temperature has exceeded the fault threshold (p0605) or the timer stage (p0606)
after the alarm threshold was exceeded (p0604) has expired.
This results in the reaction parameterized in p0610.
PTC sensor:
The tripping threshold of 1650 Ω was exceeded and the timer stage (p0606) has expired.
This results in the reaction parameterized in p0610.
A07015 drive: Motor temperature sensor alarm
An error was detected when evaluating the temperature sensor set in p0600 and p0601.
When the fault occurs, the time is started in p0607. If the fault is still present after this time
has expired, fault F07016 is output (not until at least 0.2 s after alarm A07015, however).
F07016 drive: Motor temperature sensor fault
An error was detected when evaluating the temperature sensor set in p0600 and p0601.
If alarm A07015 is present, the time in p0607 is started. If the fault is still present after this
time has expired, then fault F07016 is output; however, at the earliest, 1 s after alarm
A07015.

3.2.1 Important STARTER functions

Description
STARTER supports the following tools for managing the project:
● Copy RAM to ROM
● Download to target device
● Load to PG/PC
● Restoring the factory settings
● Commissioning wizard
● Displaying toolbars

Copy RAM to ROM

You can use this function to save volatile Control Unit data to the non-volatile memory. This
ensures that the data is still available after the 24 V Control Unit supply has been switched
off.
This function can be activated as follows:
● Tools → Setting → Download → Activate "Copy RAM to ROM"
This means that every time data is loaded to the target system by choosing "Load project
to target system", the data is stored in the non-volatile memory.
● Right-click Drive unit → Target device → Copy RAM to ROM
● Drive unit grayed out → "Copy RAM to ROM" button

NOTICE
You may only switch off the power supply to the Control Unit after saving has finished;
i.e. after saving has started, wait until it has finished and parameter p0977 has the value
0 once more.

3.2 STARTER commissioning tool

Download to target device

You can use this function to load the current STARTER project to the Control Unit. First of
all, a consistency check is performed on the project, with messages triggered if any
inconsistencies are detected. You will need to rectify any inconsistencies before performing
a download. If no inconsistencies are detected, the data is loaded to the work memory of the
Control Unit. A reset is then triggered.
This function can be activated as follows:
● Right-click Drive unit → Target device → Download to target device
● Drive unit grayed out → Download to target device button
● Online/offline comparison screen → Download to target device button
● Project to all drive units simultaneously:
Load project to target system button, Project → Download to target device menu

Load to PG/PC
You can use this function to load the current Control Unit project to STARTER.
This function can be activated as follows:
● Right-click Drive unit → Target device → Load to PG/PC
● Drive unit grayed out → Load project to PG/PC button
● Online/offline comparison screen → Load project to PG/PC button

Restoring the factory settings

You can use this function (p0970 = 1) to set all the parameters in the work memory of the
Control Unit to the factory settings. The CU305 will then perform an automatic start. All
relevant parameters found are written to the work memory (RAM). As part of this process,
various factory-set parameters are automatically updated to actual (more recent) values.
Once this automatic configuration is complete, a project with all available drive parameters
for the actual arrangement will be available in the target system.
This function, which is called "Restore factory settings", can be activated as follows:
● Right-click Drive unit → Target device → Restore factory settings
● Drive unit grayed out → Restore factory settings button

Displaying toolbars
The toolbars can be activated by choosing View → Toolbars (check mark).

Creating and copying data sets (offline)

Drive and command data sets (DDS and CDS) can be added in the drive's configuration
screen. The corresponding buttons must be clicked.
For more information about data sets, see the Drive system principles chapter.

4.1.5 CANopen functionality CU305 CAN

Introduction
The CU305 CAN supports the CANopen transfer types with SDOs (service data objects) and
PDOs (process data objects).
The CU305 CAN also supports free PDO mapping.
The CU305 CAN supports CANopen communication profile DS 301 version 4.0, device
profile DSP 402 (drives and motion control) version 2.0, and indicator profile DR303-3
version 1.0.
For communication monitoring purposes, the CU305 CAN supports node guarding and the
heartbeat protocol (heartbeat producer).
The CU305 CAN features an SDO → parameter channel that can be used to read or write all
the SINAMICS parameters.
The CU305 CAN firmware supports Profile Velocity Mode.

Node guarding
SINAMICS waits a certain time (node lifetime) for message frames from the master
application and permits a specific number (lifetime factor) of failures within a specified time
interval (node guard time).
The node lifetime is calculated by multiplying the node guard time by the lifetime factor.

Heartbeat protocol
SINAMICS (producer) cyclically transmits (heartbeat time) its communication status (sign of
life) on the CAN bus to the master application.

Profile velocity mode

Velocity setpoint defaults and settings can be made in this mode.

CANopen object directory

When the drive objects are initialized, the CANopen objects are initialized in the object
directory for the SINAMICS drive line-up (CANopen slave software).

Objects
The following SINAMICS objects are involved in communication:
1. Control Unit communication objects independent of the drive
– include: Number and number of errors, communication addresses etc.
2. Drive-dependent communication objects
– Up to eight PDOs for sending and eight PDOs for receiving can be parameterized for
the drive. Each PDO contains:
- Communication and
- Mapping parameters (max. 8 bytes/4 words/64 bits)
3. Manufacturer-specific objects
– Objects for accessing SINAMICS parameters
– Free objects for sending/receiving process data, there are freely interconnectable
objects available for each drive object (max. 16) in the object directory (see CANopen
manual for table).
– The manufacturer-specific range starts in the object directory from address 2000 hex
and ends at 5FFF hex.

4.2.7 Monitoring

Introduction
SINAMICS supports the following two optional monitoring services to ensure the functionality
of CANopen network nodes:
● Heartbeat:
SINAMICS (producer) cyclically transmits (heartbeat time) its communication status on
the CAN bus to the master application.
● Node guarding:
SINAMICS waits a certain time (node lifetime) for master frames from the master
application and permits a specific number (lifetime factor) of failures within a specified
time interval (node guard time).
The node lifetime is calculated by multiplying the node guard time by the lifetime factor.

Note
Only one node monitoring service can be activated at any one time (either heartbeat or
node guarding).
If both monitoring services are activated, node guarding is effective.

Steps
On the Monitoring tab, enter the required monitoring service (heartbeat or node guarding).
1. Select the Monitoring tab.
2. The default commissioning value for the Heartbeat monitoring mechanism could be, for
example, 100 ms. Enter this value (unless it has already been entered).
3. The default commissioning values for the node guarding monitoring service could be:
– Time interval (guard time): 100 ms
– Number of failures (lifetime factor): 3
Enter these values (unless they have already been entered).

This chapter describes the following diagnostic features of the SINAMICS S drive system:
● Diagnostics via LEDs
● Diagnostics via STARTER
● Diagnostic buffer
● Fault and alarm messages

5.1 Diagnostics via LEDs

5.1.1 LEDs when the Control Unit is booted

The individual statuses during the booting procedure are indicated by means of the LEDs on
the Control Unit.
● The duration of the individual statuses varies.
● If an error occurs, booting is aborted and the cause of the error is indicated via the LEDs.
Remedy:
– If booting is cancelled as a result of incorrect data, fault F01018 is output. After this
fault has been output, the module is booted based on factory settings.
– In all other cases: Exchange the Control Unit.
● Once the unit has been successfully booted, all the LEDs are switched off briefly.
● Once the unit has been booted, the LEDs are driven via the loaded software.
The description of the LEDs after booting applies.

5.2.1 Function generator

Description
The function generator is used, for example, for the following tasks:
● To measure and optimize control loops.
● To compare the dynamic response of coupled drives.
● To specify a simple traversing profile without a traversing program.
Use the function generator to generate different signal shapes.
In the connector output operating mode (r4818), the output signal can be injected into the
control loop via the BICO interconnection.
Depending on the mode set, this setpoint can also be applied to the control structure as, for
example, a current setpoint, disturbing torque, or speed setpoint. The impact of
superimposed control loops is automatically suppressed.

Parameterizing and operating the ramp-function generator

Use the STARTER parameterization and commissioning tool to parameterize and operate
the function generator.

5.2.3 Measuring function

Description
The measuring function is used for optimizing the drive controller. By parameterizing the
measuring function, the impact of superimposed control loops can be suppressed selectively
and the dynamic response of the individual drives analyzed. The ramp-function generator
and trace function are linked for this purpose. The control loop is supplied with the ramp-
function generator signal at a given point (e.g. speed setpoint) and recorded by the trace
function at another (e.g. speed actual value). The trace function is parameterized
automatically when the measuring function is parameterized. Specific predefined operating
modes for the trace function are used for this purpose.

Parameterizing and using the measuring function

The measuring function is parameterized and operated via the parameterization and
commissioning tool STARTER.

Figure 5-11 Signal chart for measuring sockets

Which signal can be output via measuring sockets?

The signal to be output via a measuring socket is specified by parameterizing the connector
input p0771[0...1].

Important measuring signals (examples)

r0060 CO: Speed setpoint before speed setpoint filter

r0063 CO: Actual speed value
r0069[0...2] CO: Phase currents actual value
r0075 CO: Field-generating current setpoint
r0076 CO: Field-generating actual current
r0077 CO: Torque-generating current setpoint
r0078 CO: Torque-generating actual current

Scaling
Scaling specifies how the measuring signal is processed. A straight line with 2 points must
be defined for this purpose.
Example:
x1 / y1 = 0.0% / 2.49 V x2 / y2 = 100.0% / 4.98 V (default setting)
– 0.0% is mapped onto 2.49 V
– 100.0% is mapped onto 0.00 V

Function Manual
Function Manual, 11/2009, 6SL3097-4AB10-0BP1 101
Diagnostics
5.2 Diagnostics via STARTER

Offset
The offset is applied additively to the signal to be output. The signal to be output can thus be
displayed within the measuring range.

Limitation
● Limitation on
If signals are output outside the permissible measuring range, the signal is limited to
4.98 V or to 0V.
● Limitation off
The output of signals outside the permissible measuring range causes a signal overflow.
In the event of an overflow, the signal jumps from 0 V to 4.98 V or from 4.98 to 0 V.

Example of a measurement
Assumption:
The actual speed (r0063) is to be output for a drive via measuring socket T1.
How do you do it?
1. Connect and set the measuring device.
2. Interconnect the signal (e.g. STARTER).
Interconnect the connector input (CI) belonging to the measuring socket with the desired
connector output (CO).
CI: p0771[1] = CO: r0063
3. Parameterize the signal characteristic (scaling, offset, limitation).

5.3 Fault and alarm messages

5.3.1 General information about faults and alarms

Description
The errors and states detected by the individual components of the drive system are
indicated by messages.
The messages are categorized into faults and alarms.

Note
The individual faults and alarms are described in the SINAMICS S110 List Manual in the
section titled "Faults and Alarms". Here you can also find a chapter titled "Function
diagrams" → "Faults and alarms", which contains function diagrams for the fault buffer, alarm
buffer, fault trigger, and fault configuration.

Properties of faults and alarms

● Faults
– Are identified by Fxxxxx.
– Can lead to a fault reaction.
– Must be acknowledged once the cause has been remedied.
– Status via Control Unit and LED RDY.
– Status via PROFIBUS status signal ZSW1.3 (fault active).
– Entry in the fault buffer.
● Alarms
– Are identified by Axxxxx.
– Have no further effect on the drive.
– The alarms are automatically reset once the cause has been remedied. No
acknowledgment is required.
– Status via PROFIBUS status signal ZSW1.7 (alarm active).
– Entry in the alarm buffer.
● General properties of faults and alarms
– Can be configured (e.g. change fault to alarm, fault reaction).
– Triggering on selected messages possible.
– Initiation of messages possible via an external signal.

5.3 Fault and alarm messages

Acknowledgment of faults
The list of faults and alarms specifies how each fault is acknowledged after the cause has
been remedied.
1. Acknowledgment of faults by "POWER ON"
– Switch the drive on/off (POWER ON)
2. Acknowledgment of faults by "IMMEDIATE"
– Via PROFIBUS control signal
STW1.7 (reset fault memory): 0/1 edge
Set STW1.0 (ON/OFF1) = "0" and "1"
– Via external input signal
Binector input and interconnection with digital input
p2103 = "Requested signal source"
Across all of the drive objects (DO) of a Control Unit
p2102 = "Requested signal source"
3. Acknowledge faults with "PULSE INHIBIT"
– The fault can only be acknowledged with a pulse inhibit (r0899.11 = 0).
– The same possibilities are available for acknowledging as described under
acknowledge IMMEDIATELY.

Note
The drive cannot resume operation until all active faults have been acknowledged.

5.3.2 Buffer for faults and alarms

Note
The contents of the fault buffer are saved to non-volatile memory when the Control Unit is
powered down, i.e. the fault buffer history is still available when the unit is powered up again.

NOTICE
The entry in the fault/alarm buffer is made after a delay. For this reason, the fault/alarm
buffer should not be read until a change in the buffer is also recognized (r0944, r2121) after
"Fault active"/"Alarm active" is output.

Figure 5-12 Structure of the fault buffer

Properties of the fault buffer

● A new fault incident encompasses one or more faults and is entered in "Current fault
incident".
● The entries appear in the buffer according to the time at which they occurred.
● If a new fault incident occurs, the fault buffer is reorganized. The history is recorded in
"Acknowledged fault incident" 1 to 7.
● If the cause of at least one fault in "Current fault incident" is remedied and acknowledged,
the fault buffer is reorganized. Faults that have not been remedied remain in "Current
fault incident".
● If "Current fault incident" contains eight faults and a new fault occurs, the fault in the
parameters in index 7 is overwritten by the new fault.
● r0944 is incremented each time the fault buffer changes.
● A fault value (r0949) can be output for a fault. The fault value is used to diagnose the fault
more accurately; please refer to the fault description for details of the meaning.

5.3 Fault and alarm messages

Note
Only those messages which are listed in the indexed parameters can be changed as
desired. All other message settings retain their factory settings or are reset to the factory
settings.
Examples:
• In the case of messages listed via p2128[0...19], the message type can be changed. The
factory setting is set for all other messages.
• The fault response of fault F12345 has been changed via p2100[n]. The factory settings
are to be restored.
– p2100[n] = 0

Triggering on messages (example)

Select message Trigger signal

p2128[0] = 1001 BO: r2129.0
or
p2128[1] = 1002 BO: r2129.1

Note
The value from CO: r2129 can be used as group trigger.
CO: r2129 = 0 No selected message has been output.
CO: r2129 > 0 Group trigger.
At least one selected message has been output.
The individual binector outputs BO: r2129 should be investigated.

Triggering messages externally

If the appropriate binector input is interconnected with an input signal, fault 1, 2 or 3 or alarm
1, 2 or 3 can be triggered via an external input signal.
Once an external fault (1 to 3) has been triggered on the Control Unit drive object, this fault
is also present on all associated drive objects. If one of these external faults is triggered on a
different drive object, it is only present on that particular drive object.

BI: p2106 → External fault 1 → F07860(A)

BI: p2107 → External fault 2 → F07861(A)
BI: p2108 → External fault 3 → F07862(A)
BI: p2112 → External alarm 1 → A07850(F)
BI: p2116 → External alarm 2 → A07851(F)
BI: p2117 → External alarm 3 → A07852(F)

5.3 Fault and alarm messages

Note
An external fault or alarm is triggered by a 1/0 signal.
An external fault and alarm do not usually mean that an internal drive message has been
generated. The cause of an external fault and warning should, therefore, be remedied
outside the drive.

5.3.5 Forwarding of faults and alarms

Forwarding of faults and alarms of the CU

When faults or alarms are triggered on the drive object of the CU, it is always assumed that
central functions of the drive unit are affected. For this reason, these faults and alarms are
not only signaled on the drive object of the CU, but are also forwarded to all other drive
objects. The fault reaction affects the drive object of the CU and all other drive objects.
A fault that is set on the drive object of the CU must be acknowledged on all drive objects to
which this fault was forwarded. In this way, the fault is then automatically acknowledged on
the drive object of the CU. Alternatively all faults of all drive objects can also be
acknowledged on the CU.
If a set alarm is reset on the drive object of the CU, this alarm also disappears automatically
on the other drive objects to which this alarm was forwarded.

Forwarding of faults and alarms due to BICO interconnections

If two or more drive objects are connected via BICO interconnections, faults and alarms of
CU-type drive objects are forwarded to SERVO-type drive objects.

Fault and alarm classes

There are differentiated alarm messages in the cyclic telegrams between the former alarm
classes "Alarm" and "Fault". Therefore there are 3 additional levels of alarm between the
"pure" alarm and the fault.
The function permits a higher-level control (SIMATIC, SIMOTION, SINUMERIK, etc.) to have
different control reactions to alarm messages from the drive.
The new statuses act as alarms for the drive, therefore there is NO immediate reaction from
the drive (like for the former level "alarm").
Information on alarm classes are described in status word ZSW2 at bit positions bit 5 - 6 (for
SINAMICS) or bit 11-12 (SIMODRIVE 611) (see also "ZSW2" in the chapter "Cyclic
Communication").
ZSW2: Valid for SINAMICS Interface Mode p2038=0 (function diagram 2454)
Bit 5 - 6 Alarm classes alarms
= 0: Alarm (former alarm level)
= 1: Alarm class W_NCA alarms
= 2: Alarm class W_NCB alarms
= 3: Alarm class W_NCC alarms

110 Function Manual, 11/2009, 6SL3097-4AB10-0BP1

5.3 Fault and alarm messages

ZSW2: Valid for SIMODRIVE 611 Interface Mode p2038=1 (function diagram 2453)
Bit 11 - 12 Alarm classes alarms
= 0: Alarm (former alarm level)
= 1: Alarm class W_NCA alarms
= 2: Alarm class W_NCB alarms
= 3: Alarm class W_NCC alarms
These attributes for differentiating the alarms are assigned implicitly to the appropriate alarm
numbers. The reaction to the existing alarm classes in the alarm is defined by the user
program in the higher-level control.
Explanations of the alarm classes
● W_NCA: Drive operation currently not limited
– e.g. alarm when measurement systems inactive
– no limitation on current movement
– Prevent possible switching to the defective measuring system
● W_NCB: Time-limited operation
– e.g. prewarning temperature: without further action the drive may need to be switched
off
– after a timer stage → additional fault
– after exceeding a trip threshold → additional fault
● W_NCC: Functionally limited operation
– e.g. reduced voltage/current/torque/speed limits (i2t)
– e.g. continue with reduced accuracy / resolution
– e.g. continue without encoder

Description
When commissioning the drive, it can be controlled via the BOP20. A control word is
available on the Control Unit drive object (r0019) for this purpose, which can be
interconnected with the appropriate binector inputs of e.g. the drive.
The interconnections do not function if a standard PROFIdrive telegram was selected as its
interconnection cannot be disconnected.

1 No coast down/coast down (OFF2) p0844
2 No quick stop/quick stop (OFF3) p0848
Note:
For simple commissioning, only bit 0 should be interconnected. When interconnecting bits 0 ... 2,
then the system is powered-down according to the following priority: OFF2, OFF3, OFF1.

7.1 Servo control
This type of closed-loop control enables operation with a high dynamic response and
precision for a motor with a motor encoder.

7.1.1 Speed controller

The speed controller controls the motor speed using the actual values from the encoder
(operation with encoder) or the calculated actual speed value from the electric motor model
(operation without encoder).

Properties
● Speed setpoint filter
● Speed controller adaptation

Note
Speed and torque cannot be controlled simultaneously. If speed control is activated, this has
priority over torque control.

Limits
The maximum speed p1082[D] is defined with default values for the selected motor and
becomes active during commissioning. The ramp-function generators refer to this value.

Description
Two adaptation methods are available, namely free Kp_n adaptation and speed-dependent
Kp_n/Tn_n adaptation.
Free Kp_n adaptation is also active in "operation without encoder" mode and is used in
"operation with encoder" mode as an additional factor for speed-dependent Kp_n adaptation.
Speed-dependent Kp_n/Tn_n adaptation is only active in "operation with encoder" mode and
also affects the Tn_n value.
Function diagram 5050 (see SINAMICS S110 List Manual) illustrates how speed controller
adaptation operates.

Example of speed-dependent adaptation

Note
This type of adaptation is only active in "operation with encoder" mode.

7.1.4 Torque-controlled operation

Description
An operating mode switchover (p1300) or binector input (p1501) can be used to switch from
speed control to torque control mode. All torque setpoints from the speed control system are
rendered inactive. The setpoints for torque control mode are selected by parameterization.

Properties
● Switchover to torque control mode via:
– Operating mode selection
– Binector input
● Torque setpoint can be specified:
– The torque setpoint source can be selected
– The torque setpoint can be scaled
– An additional torque setpoint can be entered
● Display of the overall torque

Commissioning of torque control mode

1. Set torque control mode (p1300 = 23; p1501 = "1" signal)
2. Specify torque setpoint
– Select source (p1511)
– Scale setpoint (p1512)
– Select supplementary setpoint (1513)

● OFF1 and p1300 = 23
– Reaction as for OFF2
● OFF1, p1501 = "1" signal and p1300 ≠ 23
– No separate braking response; the braking response takes place by a drive that
specifies the torque.
– The pulses are suppressed when the brake application time (p1217) expires. Zero
speed is detected when the actual speed drops below the speed threshold (p1226) or
once the monitoring time (p1227) started when speed setpoint ≤ speed threshold
(p1226) has expired.
– Switching on inhibited is activated.
● OFF2
– Immediate pulse suppression, the drive coasts to standstill.
– The motor brake (if parameterized) is closed immediately.
– Switching on inhibited is activated.
● OFF3
– Switch to speed-controlled operation
– n_set = 0 is input immediately to brake the drive along the OFF3 deceleration ramp
(p1135).
– When zero speed is detected, the motor brake (if parameterized) is closed.
– The pulses are suppressed when the motor brake application time (p1217) has
elapsed. Zero speed is detected when the actual speed drops below the speed
threshold (p1226) or once the monitoring time (p1227) started when speed setpoint ≤

7.1.5 Torque setpoint limitation

Description
The steps required for limiting the torque setpoint are as follows:
1. Define the torque setpoint and an additional torque setpoint
2. Generate torque limits
The torque setpoint can be limited to a maximum permissible value in all four quadrants.
Different limits can be parameterized for motor and regenerative modes.

Note
This function is effective immediately without any settings. The user can also define further
settings for limiting the torque.

Properties
The connector inputs of the function are initialized with fixed torque limits. If required, the
torque limits can also be defined dynamically (during operation).
● A control bit can be used to select the torque limitation mode. The following alternatives
are available:
– Upper and lower torque limit
– Motor and regenerative torque limit
● Additional power limitation configurable
– Motor mode power limit
– Regenerative mode power limit
● The following factors are monitored by the current controller and therefore always apply
in addition to torque limitation:
– Stall power
– Maximum torque-generating current
● Offset of the setting values also possible (see "Example: Torque limits with or without
offset").
● The following torque limits are displayed via parameters:
– Lowest of all upper torque limits with and without offset
– Highest of all lower torque limits with and without offset

Variants of torque limitation

The following variants are available:
1. No settings entered:
The application does not require any additional restrictions to the torque limits.
2. Fixed limits are required for the torque:
The fixed upper and lower limits or alternatively the fixed motor and regenerative limits
can be specified separately by different sources.
3. Dynamic limits are required for the torque:
– The dynamic upper and lower limit or, alternatively, the dynamic motor and
regenerative limit can be specified separately by different sources.
– Parameters are used to select the source of the current limit.
4. A torque offset can be parameterized.
5. In addition, the power limits can be parameterized separately for motor and regenerative
mode.

NOTICE
Negative values at r1534 or positive values at r1535 represent a minimum torque for the
other torque directions and can cause the drive to rotate if no load torque is generated
to counteract this (see function diagram 5630 in the SINAMICS S110 List Manual).

7.1.7 Current setpoint filter

Description
The two current setpoint filters connected in series can be parameterized as follows:
● Low-pass 2nd order (PT2: -40 dB/decade) (type 1)
● General filter 2nd order (type 2)
Bandstop and lowpass with reduction are converted to the parameters of the general filter
2nd order via STARTER.
– Bandstop
– Low-pass with reduction by a constant value
The phase frequency curve is shown alongside the amplitude log frequency curve. A phase
shift results in a control system delay and should be kept to a minimum.
Function diagram 5710 (see SINAMICS S110 List Manual) illustrates how the current
setpoint filter operates.

7.1.8 Note about the electronic motor model

A model change takes place within the speed range p1752*(100%-p1756) and p1752. With
induction motors with encoder, the torque image is more accurate in higher speed ranges;
the effect of the rotor resistance and the saturation of the main field inductance are
corrected. With synchronous motors with encoder, the commutation angle is monitored.

7.1.9 V/f control

Description
With V/f control, the motor is operated with an open control loop and does require speed
control or actual current sensing, for example. Operation is possible with a small amount of
motor data.
V/f control can be used to check the following:
● Power Module
● Power cable between Power Module and motor
● Motor
● DRIVE-CLiQ cable between the Power Module and motor
● Encoder and actual encoder value
The following motors can be operated with V/f control:
● Induction motors
● Synchronous motors

Note
In V/f mode, the calculated actual speed value is always displayed in r0063. The speed of
the encoder (if installed) is displayed in r0061. If an encoder is not installed, r0061
displays "0".

Prerequisites for V/f control

1. First commissioning has been carried out:
The parameters for V/f control have been initialized with appropriate values.
2. First commissioning has not been carried out:
The following relevant motor data must be checked and, where necessary, corrected:
– r0313 Motor pole pair number, actual (or calculated)
– p0314 Motor pole pair number
– p0341 Motor moment of inertia
– p0342 Ratio between the total moment of inertia and that of the motor
– p0640 Current limit
– p1498[0...n] Load moment of inertia
– p1520[0...n] CO: Torque limit, upper/motoring
– p1521[0...n] CO: Torque limit, lower/regenerative
– p1530[0...n] Motor mode power limit
– p1531[0...n] Regenerative mode power limit
3. V/f control can now be commissioned.
– p1318 V/f control ramp-up/ramp-down time
– p1319 V/f control voltage at zero frequency
– p1326 V/f control programmable characteristic frequency 4
– p1327 V/f control programmable characteristic voltage 4
– p1338[0...n] V/f control mode resonance damping gain
– p1339[0...n] V/f control mode resonance damping filter time constant
– p1349[0...n] V/f control mode resonance damping maximum frequency

Note
With synchronous motors, V/f control mode is normally only stable at low speeds.
Higher speeds can induce vibrations.
Oscillation damping is activated on the basis of suitable default parameter values and
does not require further parameterization in most applications. If you become aware of
interference caused by a transient response, you have the option of gradually
increasing the value of p1338 and evaluating how this affects your system.

Note
The drive can be ramped up to the current limit (p0640) relatively quickly without the
need for extensive parameterization (when operating the drive with a variable moment
of inertia, for example).
Note the following: Only the ramp-function generator stops when the current limit
(p0640) is reached. This does not prevent the current from increasing even further. In
view of this, the parameters you set must respect a safety margin relative to the
current limits for the monitoring functions to prevent the drive from switching off (in the
event of an overcurrent fault, for example).

Commissioning V/f control

1. Verify the preconditions for V/f control mode.
2. Set p0311 → Rated motor speed
3. Set p1317 = 1 → activates the function
4. Activate the enable signals for operation
5. Specify the speed setpoint

7.1.10 Optimizing the current and speed controller

General information

CAUTION
Controller optimization may only be performed by skilled personnel with a knowledge of
control engineering.

The following tools are available for optimizing the controllers:

● "Function generator" in STARTER
● "Trace" in STARTER
● "Measuring function" in STARTER
● Measuring sockets on the Control Unit

Optimizing the current controller

The current controller is initialized when the system is commissioned for the first time and is
adequately optimized for most applications.

Optimizing the speed controller

The speed controller is set in accordance with the motor moment of inertia when the motor is
configured for the first time. The calculated proportional gain is set to approximately 30% of
the maximum possible gain in order to minimize vibrations when the controller is mounted on
the mechanical system of the machine for the first time.
The integral time of the speed controller is always preset to 10 ms.
The following optimization measures are necessary in order to achieve the full dynamic
response:
● Increase the proportional gain Kp_n (p1460)
● Change the integral action time Tn_n (p1462)

Automatic controller setting of the speed controller (frequency response analysis) in STARTER
● The automatic speed controller setting has the following features:
– Section identification using FFT analysis
– Automatic setting of filters in the current setpoint arm, e.g. for damping resonances
– Automatic setting of the controller (gain factor Kp, integral time Tn)
● The automatic controller settings can be verified with the measuring functions.
The "automatic controller setting" parameterization screen form is selected using the
following symbol in the toolbar of the STARTER commissioning tool:

Example of measuring the speed controller frequency response

By measuring the speed controller frequency response and the control system, critical
resonance frequencies can, if necessary, be determined at the stability limit of the speed
control loop and dampened using one or more current setpoint filters. This normally enables
the proportional gain to be increased (e.g. Kp_n = 3* default value).
After the Kp_n value has been set, the ideal integral action time Tn_n (e.g. reduced from 10
ms to 5 ms) can be determined.

Example of speed setpoint step change

A rectangular step change can be applied to the speed setpoint via the speed setpoint step
change measuring function. The measuring function has preselected the measurement for
the speed setpoint and the torque-generating current.

7.1.11 Sensorless operation (without an encoder)

NOTICE
The operation of synchronous motors without an encoder must be verified in a test
application. Stable operation in this mode cannot be guaranteed for every application.
Therefore, the user will be solely responsible for the use of this operating mode.

Description
This allows operation without an encoder and mixed operation (with/without encoder).
Encoderless operation with the motor model allows a higher dynamic response and greater
stability than a standard drive with V/f control. Compared with a drive with an encoder,
however, speed accuracy is lower and the dynamic response and smooth running features
deteriorate.
Since the dynamic response in operation without an encoder is lower than in operation with
an encoder, accelerating torque pre-control is implemented to improve the control dynamic
performance. It controls, knowing the drive torque, and taking into account the existing
torque and current limits as well as the load moment of inertia (motor moment of inertia:
p0341*p0342 + load torque: p1498) the required torque for a demanded speed dynamic
performance optimized from a time perspective.

Note
If the motor is operated with and without an encoder (e.g. p0491 not 0 or p1404 < p1082),
the maximum current during operation without an encoder can be reduced via p0642
(reference value is p0640) in order to minimize interfering, saturation-related motor data
changes during operation without an encoder.

A torque smoothing time can be parameterized via p1517 for the torque pre-control. The
speed controller needs to be optimized for operation without an encoder due to the lower
dynamic response. This can be carried out via p1470 (P gain) and p1472 (integral time).
In the low-speed range, the actual speed value, the orientation, and the actual flux can no
longer be calculated during operation without an encoder due to the accuracy of the
measured values and the parameter sensitivity of the technique. For this reason, an open-
loop current/frequency control is selected. The switchover threshold is parameterized via
p1755 and the hysteresis via p1756.

Function Manual
148 Function Manual, 11/2009, 6SL3097-4AB10-0BP1
 Drive functions
7.1 Servo control

To accept a high load torque even in the open-loop controlled range, the motor current can
be increased via p1612. To do so, the drive torque (e.g. friction torque) must be known or
estimated. An additional reserve of approx. 20% should also be added. In synchronous
motors, the torque is converted to the current via the motor torque constant (p0316). In the
lower speed range, the required current cannot be measured directly on the Power Module.
The default setting is 50% (synchronous motor) or 80% (induction motor) of the motor rated
current (p0305). When parameterizing the motor current (p1612), you must take into account
the thermal motor load.

Note
Encoderless operation is not permitted for vertical axes or similar. Encoderless operation is
not suitable for a higher-level closed-loop position control either.

The start behavior of synchronous motors from standstill can be improved further by
parameterizing the pole position identification (p1982 = 1).

Behavior once pulses have been canceled

Once the pulses have been canceled in operation without an encoder, the current actual
speed value of the motor can no longer be calculated. Once the pulses are enabled again,
the system must search for the actual speed value.
p1400.11 can be used to parameterize whether the search is to begin with the speed
setpoint (p1400.11 = 1) or with speed = 0.0 (p1400.11 = 0). Under normal circumstances,
p1400.11 = 0 because the motor is usually started from standstill. If the motor is rotating
faster than the changeover speed p1755 when the pulses are enabled, p1400.11 = 1 must
be set.
If the motor is rotating and the start value for the search is that of the setpoint (p1400.11 =
1), the speed setpoint must be in the same direction as the actual speed before the pulses
can be enabled. A large discrepancy between the actual and setpoint speed can cause a
malfunction.

WARNING
Once the pulses have been canceled, no information about the motor speed is available.
The computed actual speed value is then set to zero, which means that all actual speed
value messages and output signals are irrelevant.

Switchover between closed-loop/open-loop operation and operation with/without encoder

Operation without an encoder is activated via parameter setting p1300 = 20. If p1300 = 20 or
p1404 = 0, operation without an encoder is active across the entire speed range. If the
speed value is less than the changeover speed p1755, the motor is operated in accordance
with the current/frequency.
During operation with an encoder, a switchover can be made to operation without an
encoder when the speed threshold p1404 is exceeded. If p1404 > 0 and p1404 < p1755, a
switchover is not made to operation without an encoder until the speed exceeds p1755.
Operation without an encoder is displayed in parameter r1407.1.

Note
In closed-loop control operating mode "Speed controller without encoder", a rotor position
encoder is not required. Since a temperature monitor is not usually connected in this case
either, this must be parameterized via p0600 = 0 (no sensor).

Series reactor
When high-speed special motors are used, or other low leakage induction motors, a series
reactor may be required to ensure stable operation of the current controller.
The series reactor can be integrated via p0353.

Commissioning/optimization
1. Estimate the motor current p1612 on the basis of the mechanical conditions (I = M/kt).
2. Set Kn (p1470) and Tn (p1472) above I/f operation (> p1755). The load moment of inertia
should be set to zero here (p1498 = 0), since this deactivates part of the torque pre-
control.
3. Determine the load moment of inertia in the speed range above I/f operation (> p1755) by
setting p1498 via a ramp response (e.g. ramp time 100 ms) and assessing the current
(r0077) and model speed (r0063).

7.1.12 Motor data identification

Description
Motor data identification (MotID) provides a means of determining motor data (of third-party
motors, for example). The drive system must have been commissioned for the first time as
basis for using MotID. To do this, either the electrical motor data (motor data sheet) or the
rating plate data must be entered and the calculation of the motor/control parameters
(p0340) must have been completed.
Commissioning involves the following steps:
● Enter the motor data or the rating plate data and the encoder data
● Complete calculation of the motor and control data as starting value for the MotID
(p0340 = 3, if motor data, p0340 = 1, if rating plate data were entered)
● Carry out a static measurement (p1910)
● For synchronous motors: Carry out an angular commutation calibration (p1990) and if
required, fine synchronization (refer to r1992)
● Carry out a rotating measurement (p1960)
Before starting the rotating measurement, the speed controller setting should be checked
and optimized (p1460, p1462 and p1470, p1472).
It is preferable if the rotating MotID is carried out with the motor de-coupled from the
mechanical system. This therefore means that only the motor moment of inertia is
determined. The total moment of inertia with mechanical system can be subsequently
identified with p1959 = 4 and p1960 = 1. The stress on the mechanical system can be
reduced by parameterizing the ramp-up time (p1958) and/or using a speed limit
(p1959.14/p1959.15) or using the current and speed limit. The higher the selected ramp-
up time, the less accurate the moment of inertia determined.

Note
Completion of the individual identification runs can be read via parameters r3925 to
r3928.

The enable signals OFF1, OFF2, OFF3 and "enable operation" remain effective and can be
interrupt the motor identification routine.
If there is an extended setpoint channel (r0108.08 = 1), parameters p1959.14 = 0 and
p1959.15 = 0 and a direction of rotation limit (p1110 or p1111) is active there, then this is
observed at the instant of the start via p1960. For p1958 = -1, the ramp-up and ramp-down
time of the setpoint channel (p1120 and p1121) are also used for the MotID.

Note
If a ramp-up/ramp-down time or one direction of rotation limit is activated, parts of the motor
data identification routine cannot be carried out. For other parts of the motor data
identification routine, the accuracy of the results is diminished because a ramp-up/ramp-
down time is selected. If possible, p1958 should be 0 and no direction of rotation limit
selected (p1959.14 = 1 and p1959.15 = 1).

7.1 Servo control

DANGER
The stationary MotID can result in slight movement of up to 210 degrees electrical.
For the rotating motor data identification routine, motor motion is initiated capable of
reaching the maximum speed (p1082) and the motor torque corresponding to the maximum
current (p0640).
The rotating measurement should be carried out with a motor running at no load (de-
coupled from the mechanical system) in order to prevent damage/destruction to the load or
be influenced by the load. If the motor cannot be de-coupled from the mechanical system,
then the stress on the mechanical system can be reduced by parameterizing the ramp-up
time (p1958) and/or using a speed limit (p1959.14/p1959.15) or using the current and
speed limit.
If a mechanical distance limit has been set, you are advised not to carry out the rotating
measurement.
The emergency OFF functions must be fully operational during commissioning.
To protect the machines and personnel, the relevant safety regulations must be observed.

If a brake is being used and is operational (p1215 = 1, 3), then the stationary measurement with closed brake is carried
out. If possible (e.g. no hanging/suspended axis), we recommend that the brake is opened before the MotID (p1215 = 2).
This also means that the encoder size can be adjusted and the angular commutation calibrated.

7.1.13 Pole position identification

Description
For synchronous motors, the pole position identification determines its electrical pole
position, that is required for the field-oriented control. Generally, the electrical pole position is
provided from a mechanically adjusted encoder with absolute information. In this case, pole
position identification is not required. For the following encoder properties, pole position
identification is not required:
● Absolute encoder (e.g. EnDat, DRIVE-CLiQ encoder)
● Encoder with C/D track and pole pair number ≤ 8
● Hall sensor
● Resolver with a multiple integer ratio between the motor pole pair number and the
encoder pole pair number
● Incremental encoder with a multiple integer ratio between the motor pole pair number and
the encoder pulse number
The pole position identification is used for:
● Determining the pole position (p1982 = 1)
● Determining the angular commutation offset during commissioning (p1990 = 1)
● Plausibility check for encoders with absolute information (p1982 = 2)

WARNING
When the motors are not braked, the motor rotates or moves as a result of the current
impressed during the measurement. The magnitude of the motion depends on the
magnitude of the current and the moment of inertia of the motor and load.

Notes regarding pole position identification

The relevant technique can be selected using parameter P1980. The following techniques
are available for pole position identification:
● Saturation-based 1st+ 2nd harmonics (p1980 = 0)
● Saturation-based 1st harmonics (p1980 = 1)
● Saturation-based, two-stage (p1980 = 4)
● Saturation-based (p1980 = 10)
The following supplementary conditions apply to the saturation-based motion technique:
● You can use the techniques for both braked and non-braked motors.
● It can only be used for a speed setpoint = 0 or from standstill.
● The currents specified (p0325, p0329) must be sufficiently large to provide a meaningful
measuring result.

● With 1FK7 motors, two-stage procedures must not be used (p1980 = 4). The value in
p0329, which is set automatically, must not be reduced.
For the motion-based technique, the following supplementary conditions apply:
● The motor must be free to move and it may not be subject to external forces (no
hanging/suspended axes)
● It can only be used for a speed setpoint = 0 or from standstill.
● If there is a motor brake, then this must be open (p1215 = 2).
● The specified current magnitude (p1993) must move the motor by a sufficient amount.

WARNING
Before using the pole position identification routine, the control sense of the speed
control loop must be corrected (p0410.0).
For rotating motors, in encoderless operation with a small positive speed setpoint (e.g.
10 RPM), the speed actual value (r0061) and the speed setpoint (r1438) must have the
same sign.

Pole position determination with zero marks

The pole position identification routine provides coarse synchronization. If zero marks exist,
the pole position can be automatically compared with the zero mark position once the zero
mark(s) have been passed (fine synchronization). The zero mark position must be either
mechanically or electrically (p0431) calibrated. If the encoder system permits this, then we
recommend fine synchronization (p0404.15 = 1). This is because it avoids measurement
spread and allows the determined pole position to be additionally checked.

Suitable zero marks are:

● One zero mark in the complete traversing range
● Equidistant zero marks whose relevant position to the commutation are identical
● Distance-coded zero marks

7.1.14 Vdc control

Description
Vdc control can be activated if overvoltage or undervoltage is present in the supply voltage.
This prevents a fault from occurring due to the supply voltage and ensures that the drive is
always ready to use.
This function is activated by means of the configuration parameter (p1240). It can be
activated if an overvoltage or undervoltage is present. The torque limit of the motor at which
the Vdc controller is active can be affected if discrepancies in the supply voltage are
significant enough. The motor may no longer be able to maintain its setpoint speed or the
acceleration/braking phases could be prolonged.
The Vdc controller is an automatic P controller that influences the torque limits. It only
intervenes when the supply voltage approaches the "upper threshold" (p1244) or "lower
threshold" (p1248) and the corresponding controller is activated via the configuration
parameter (p1240).
An application for the Vdc controller is, for example, as a safety measure in the event of a
power failure (Vdc_min and Vdc_max controller).

The voltage limit values for Vdc control also have an impact on V/f control, although the
dynamic response of Vdc control is slower in this case.

Figure 7-22 Switching Vdc_min control on/off (kinetic buffering)

In the event of a power failure, the Power Module will no longer be able to maintain the
supply voltage, particularly if the motor is drawing active power. To maintain the supply
voltage in the event of a power failure (e.g. for a controlled emergency retraction), the
Vdc_min controller can be activated for the drive. If the voltage threshold set in p1248 is
undershot, this drive will be decelerated so that its kinetic energy can be used to maintain
the supply voltage. The threshold should be considerably higher than the trip threshold of the
motor (recommendation: 50 V below the supply voltage). When the power supply is restored,
the Vdc controller is automatically deactivated and the drive will ramp back up to the speed
setpoint. If the supply voltage cannot be restored, the power supply will fail once the kinetic
energy of the drive has been exhausted with an active Vdc_min controller.

Note
You must make sure that the converter is not disconnected from the power supply. It could
become disconnected, for example, if the line contactor drops out. The line contactor would
need to have an uninterruptible power supply (UPS), for example.

Description of Vdc_min control without braking (p1240 = 8, 9)

As with p1240 = 2, 3, however, active motor braking can be prevented by a reduction in the
supply voltage. The effective upper torque limit must not be less than the torque limit offset
(p1532). The motor does not switch to regenerative mode and no longer draws any active
power from the DC link.

Figure 7-23 Switching-in/switching-out the Vdc_max control

In the event of a power failure, the voltage can increase until it reaches the shutdown
threshold when the drive is decelerated. The Vdc_max controller can be activated to prevent
the system from shutting down due to overvoltage. The Vdc_max controller is normally
activated for drives that have to decelerate/accelerate high levels of kinetic energy
themselves. When the overvoltage threshold in p1244 is reached (recommended setting: 50
V higher than the supply voltage), the braking torque of the drive with an active Vdc_max
controller is reduced by shifting the torque limit. In this way, the drive feeds back the same
amount of energy that is assimilated as a result of losses or consumers, thereby minimizing
the braking time.

Description of Vdc_max control without acceleration (p1240 = 7, 9)

As with p1240 = 1, 3, if the drive must not be accelerated by means of an increase in the
supply voltage, acceleration can be prevented by setting p1240 = 7, 9. The effective lower
torque limit must not be greater than the torque limit offset (p1532).

Description of Vdc controller monitoring functions (p1240 = 4, 5, 6)

In the event of a power failure, the supply voltage can increase until it reaches the shutdown
threshold when the drive is decelerated. To ensure that uncritical drives do not attempt to
draw power from the supply voltage in the event of a power failure, such drives can be
switched off by a fault (F07404) with a parameterizable voltage threshold (p1244). This is
carried out by activating the Vdc_max monitoring function (p1240 = 4, 6).

7.1.15 Dynamic Servo Control (DSC)

Description
The function Dynamic Servo Control" (DSC) is a closed-loop control structure which is
computed in a fast speed controller clock cycle and is supplied with setpoints by the control
in the position controller clock cycle.
This allows higher position controller gain factors to be achieved.
The following prerequisites are necessary to use the "Dynamic Servo Control" function:
● n-set mode
● Isochronous PROFIBUS-DP
● The position controller gain factor (KPC) and the position deviation (XERR) must be
included in the PROFIBUS-DP setpoint telegram (refer to p0915).
● The position actual value must be transferred to the master in the actual value telegram
of PROFIBUS-DP via the encoder interface Gx_XIST1.
● When DSC is activated, the speed setpoint N_SOLL_B from the PROFIBUS DP telegram
is used as speed pre-control value.
● The internal quasi position controller uses the position actual value from the motor
measuring system (G1_XIST1) or the position actual value from the additional encoder
system (free telegrams).

Further PZD data telegram types can be used with the telegram extension. It must then be
ensured that SERVO supports a maximum of 16 PZD setpoints and 19 PZD actual values.

Note
Synchronization is required on the control side and on the drive side for the operation of
DSC.

Figure 7-24 Control principle using DSC

Activating
If the prerequisites for DSC are met, the DSC structure is activated through a logical
combination of the parameters p1190 "DSC position deviation XERR" and p1191 "DSC
position controller gain KPC" through a selected suitable PROFIdrive telegram.
If KPC = 0 is issued, only speed control with the speed pre-control value (p1430, typically
N_SOLL_B) can be used. Position controlled operation requires a transfer of KPC > 0.
When DSC is activated, it is recommended to use a new setting for the position controller
gain KPC in the master.
When DSC is activated, the channels p1155 and p1160 for the position setpoint values as
well as the channel for the extended setpoint value are not used.
The p1430 value for speed pre-control is still taken into account.

Deactivating
If both KPC = 0 (p1191=0) and XERR = 0 (p1190 = 0) are set, the DSC structure is dissolved
and the "DSC" function is deactivated. In this case, only the value from p1430 from speed
pre-control is taken into account.
Since it is possible to set higher gain factors using DSC, the control loop can become
unstable when DSC is disabled. For this reason, before deactivating DSC, the value for KPC
in the master must be reduced.

 Drive functions
7.1 Servo control

Speed setpoint filter

A speed setpoint filter to smoothen the speet setpoint steps is no longer required when DSC
is active.
When using the "DSC" function, it only makes sense to use speed setpoint filter 1 to support
the position controller, e.g. to suppress resonance effects.

External encoder systems (except motor encoder)

If, with DSC active, an external encoder is to be used, this requires the selection of a
telegram with additional encoder actual values: Free telegrams.
For optimum control in DSC mode, the same encoders must be used for the controller
(Master) and the drive via the parameter p1192 "DSC encoder selection".
Since the motor encoder is no longer used in this case, the adaptation factor for the
conversion of the selected encoder system into the motor encoder system is determined
using parameter p1193 "DCS encoder adaptation factor". The factor represents the ratio of
the pulse difference between the motor encoder and the used encoder for the same
reference distance.
The effect of the parameters p1192 and p1193 is illustrated in function diagram 3090.

Diagnostics
Via the parameter r1407.4 = 1 it can be indicated whether the speed setpoint of DSC is
used.
Preconditions for the indication:
● p1190 and p1191 must be connected to a signal source with a value of > 0
(DSC structure activated).
● OFF1, OFF2 and OFF3 must not be active.
● The motor data identification must not be active.
● Master control must not be active.

The "DSC" function cannot be active under the following conditions:

● Isochronous mode has not been selected (r2054 ≠ 4).
● PROFIBUS is not isochronous (r2064[0] ≠ 1).
● On the control side, DSC is not active, which causes the value of KPC = 0 to be
transmitted to p1191.

7.1.16 Travel to fixed stop

Description
This function can be used to move a motor to a fixed stop at a specified torque without a
fault being signaled. When the stop is reached, the specified torque is built up and remains
applied.
The desired torque derating is brought about by scaling the upper/motor-mode torque limit
and the lower/regenerative-mode torque limit.

Application examples
● Screwing parts together with a defined torque.
● Moving to a mechanical reference point.

When PROFIBUS telegrams 2 to 4 are used, the following are automatically interconnected:
● Control word 2, bit 8
● Status word 2, bit 8
Also with PROFIdrive telegrams 102 and 103:

When PROFIdrive telegrams 2 to 4 are used, no torque reduction is transmitted. When the
"Travel to fixed stop" function is activated, the motor ramps up to the torque limits specified
in p1520 and p1521. If the torque has to be reduced, telegrams 102 and 103, for example,
can be used for transmission. Another option would be to enter a fixed value in p2900 and
interconnect it to the torque limits p1528 and p1529.

7.1.17 Vertical axes

Description
With a vertical axis without mechanical weight compensation, electronic weight
compensation can be set by offsetting the torque limits (p1532). The torque limits specified in
p1520 and p1521 are shifted by this offset value.
The offset value can be read in r0031 and transferred in p1532.
To reduce compensation once the brake has been released, the torque offset can be
interconnected as a supplementary torque setpoint (p1513). In this way, the holding torque is
set as soon as the brake has been released.

7.1.18 Variable signaling function

Description
The variable signaling function can be used to monitor BICO sources and parameters (with
the attribute "traceable") for violation of an upper or lower threshold value (p3295).
A hysteresis (p3296) can be specified for the threshold value and a pull-in or drop-out delay
(p3297/8) can be specified for the output signal (p3294).
The setting of a hysteresis results in a tolerance band around the threshold value. If the
upper threshold value is exceeded the output signal is set to 1, if it drops below the lower
threshold value the output signal is reset to 0.
After the configuration is completed, the variable signaling function must be activated with
p3290.0.

Example 1:
Heating should be switched on depending on the temperature. For this the analog signal of
an external sensor is connected with the variable signaling function. A temperature threshold
and a hysteresis is defined to prevent the heating from switching on and off constantly.
Example 2:
A process variable "pressure" is to be monitored, whereby a temporary overpressure is
tolerated. For this the output signal of an external sensor is connected with the variable
signaling function. The pressure thresholds and a pull-in delay are set as tolerance time.
When the output signal of the variable signaling function is set, bit 5 in message word
MELDW is set during cyclic communication. The message word MELDW is a component of
the telegrams 102, 103, 110, 111.

7.1.19 Central probe evaluation

Description
Frequently, motion control systems have to detect and save the positions of drive axes at an
instant in time defined by an external event. For example, this external event may be the
signal edge of a probe. In this case, it may be necessary to evaluate several probes or save
the position actual values of several axes, triggered by a probe event.
For the central probe evaluation, the instant in time of the probe signal is detected and saved
by a central function. From the available sample values of the position signals of the various
axes, the position actual values at the probe instant are interpolated with respect to time in
the control. For SINAMICS S, two techniques have been implemented:
● For the probe evaluation with handshake, for each probe and positive and/or negative
probe edge, up to one measured value is evaluated each communication cycle / each
four DP cycles.
● With a parameterizable probe evaluation without handshake, the evaluation frequency of
the probe edges can be increased up to the communication frequency/application
frequency of the probe evaluation (= SERVO cycle of the higher-level control).
Precondition: T_DP = T_MACP (i.e. cycle ratio = 1:1, no cycle reduction ratio is possible).

Common features for central measuring with and without handshake

Both measuring techniques have the following points in common:
● PROFIBUS telegrams
● Synchronization between the control and drive as a precondition for measuring.
● System time: Resolution (0.25 µs), maximum value (16 ms)
● Time stamp: Format (drive increments, NC decrements)
● Monitoring functions (sign of life)
● Fault messages
● Incrementing
In the interface, the value "0" is not a valid time format and is used to express that a
measured value is not available.

Central measuring with handshake

● Evaluation technique with handshake as long as p0684 = 0
● Transfer, control word probe (BICO p0682 to PZD3) at the instant To in the MAP cycle.
● A measurement is activated with a 0/1 transition of the control bit for falling or rising edge
in the probe control word.
● If a measurement is activated, a check is made in the DP cycle as to whether a measured
value is present.
● If the check indicates that there is a measured value, then the time stamp is entered into
either p0686 or p0687.
● The time stamp is transferred until the control bit for falling or rising edge is set to zero in
the control word. Then, the associated time stamp is set to zero.

Central measurement without handshake

When selecting the evaluation technique without handshake (p0684 = 1), the measurement
for falling and rising edge is activated.
If a measurement is activated, a check is made in the DP cycle as to whether a measured
value was detected:
● If the check indicates that a measured value is available, the time stamp is entered in
either p0686 or p0687 and a new measurement is automatically activated.
● If the check indicates that a measured value is not available, then a time stamp of zero is
entered into either p0686 or p0687.
● This means that a time stamp is only transferred once before it is overwritten with zero or
a new time stamp.
● Max. edge detection cycle < 1 / T_DP

Remarks
Applications other than the application actually using the function can monitor the probe
state and read the probe measured values.
Example:
EPOS axially controls "its" probe, a control can establish a connection to the probe to read
its signals and the information can be integrated into the drive telegram.
Parameter p0684 (central probe evaluation technique) offers the following setting options:
● p0684 = 0: Measuring with handshake (factory setting)
● p0684 = 1: Measuring without handshake
● It cannot be guaranteed that the standard PROFIdrive connection will not fail
● The function "without handshake" has been released for "integrated" platforms (e.g.
SINAMICS integrated in SIMOTION D425).
● You must use the MIT handshake version to ensure absolute reliability when detecting
the probe.

7.1.20 Pulse/direction interface

Thanks to the pulse/direction interface, SINAMICS S110 can be used for simple positioning
tasks on a controller. The controller is connected to SINAMICS S110 via the encoder
interface (connector X23) of the CU305. The controller uses the following methods to give
setpoints to the drive via interface X23:
● Pulse/direction signals
or
● Incremental encoder emulation via A and B track

Application 1: Position-controlled drive

Control

Figure 7-28 "Position-controlled drive" application

The controller specifies position setpoints via the pulse/direction interface. The position
control in the drive executes all the pulses received since the enable. If the discrepancy
between the setpoint and actual positions is too great, the drive generates a fault (F07452
"LR: Following error too great").
You must then acknowledge the following error and use the "position reset" signal (see
"Control signals" table) to reset the setpoint/actual value. You should also use the "position
reset" signal in the following cases:
● Endlessly rotating axes
With endlessly rotating axes, briefly set and then cancel the "position reset" signal after
any traversing task completed by the controller. This will ensure the maximum range (32
bits) is not exceeded.
● Absolute encoder
With absolute encoders, you need to set the "position reset" signal at the outset in order
to reset the actual value and thereby enable the axis to move.

Application 2: Speed-controlled drive

The drive is subject to speed control when operating on the controller. The clock frequency
determines the speed setpoint (for details on how this is calculated, refer to the
"Commissioning the pulse/direction interface" chapter).

7.2.1 Changing over units

Description
By changing over the units, parameters and process quantities for input and output can be
changed over to an appropriate system of units (US units or as per unit quantities (%)).
The following supplementary conditions apply when changing over units:
● Parameters of the rating plate of the drive converter or the motor rating plate can be
changed over between SI/US units; however, a per unit representation is not possible.
● After changing over the units parameter, all parameters that are assigned to one of the
units group dependent on it, are all changed over to the new system of units.
● A parameter is available to select technological units (p0595) to represent technological
quantities in the technology controller.
● If the units are converted to per unit quantities and the reference quantity changed, the
percentage value entered in a parameter is not changed.
Example:
– A fixed speed of 80% corresponds, for a reference speed of 1500 RPM, to a value of
1200 RPM.
– If the reference speed is changed to 3000 RPM, then the value of 80% is kept and
now means 2400 RPM.

 Drive functions
7.2 Basic functions

Restrictions
● When a unit changeover occurs, rounding to the decimal places is carried out. This can
mean that the original value might change by up to one decimal place.
● If a referenced form is selected and the reference parameters (e.g. p2000) are changed
retrospectively, the referenced values of some of the control parameters are also
adjusted to ensure that the control behavior is unaffected.
● If the reference variables (p2000 to p2007) are changed offline in STARTER, there is a
risk that the parameter value ranges will be violated. In this case, appropriate fault
messages will be displayed when the parameters are loaded to the drive units.

Groups of units
Every parameter that can be changed over is assigned to a units group, that, depending on
the group, can be changed over within certain limits.
This assignment and the unit groups for each parameter are listed in the parameter list in the
SINAMICS S110 List Manual.
The units groups can be individually switched via the following parameters: p0100, p0505
and p0595

7.2.2 Reference parameters/normalizations

Description
Reference values equivalent to 100% are required in order to express units in percentage
terms. These reference values are entered in parameters p2000 to p2007. They are
computed during the calculation via p0340 = 1 or in STARTER during drive configuration.
After calculation in the drive, these parameters are automatically protected via p0573 = 1
against overwriting through a new calculation (p0340). This eliminates the need to adjust the
references values in a PROFIdrive controller whenever a new calculation of the reference
parameters via p0340 takes place.

Note
If a referenced form is selected and the reference parameters (e.g. p2000) are changed
retrospectively, the referenced values of some of the control parameters are also adjusted to
ensure that the control behavior is unaffected.

Using STARTER offline

Following offline drive configuration, the reference parameters are preset; they can be
changed and protected under Drive → Configuration → "Disabled list" tab.

Note
If the reference values (p2000 to p2007) are changed offline in STARTER, it can lead to
boundary violations of the parameter values, which cause fault messages during loading to
the drive.

7.2.3 Automatic restart

Description
The "automatic restart" function is used to restart the drive automatically once the power has
been restored following a power failure. In this case, all of the faults present are
automatically acknowledged and the drive is powered-up again. This function is not only
restricted to line supply faults; it can also be used to automatically acknowledge faults and to
restart the motor after any fault trips.

WARNING
If p1210 is set to value > 1, the motor can start automatically once the power supply has
been restored. This is especially critical if the motor comes to a standstill (zero speed) after
longer power failures and it is incorrectly assumed that it has been powered down. For this
reason, death, serious injury, or considerable material damage can occur if personnel enter
the working area of a motor in this condition.

1 Acknowledges all faults without When p1210 = 1, faults that are present are
restarting acknowledged automatically when their cause is
rectified. If further faults occur after faults have been
acknowledged, then these are also again
automatically acknowledged. A minimum time of
p1212 + 1 s must expire between successful fault
acknowledgment and a fault re-occurring if the
signal ON/OFF1 (control word 1, bit 0) is at a HIGH
signal level. If the ON/OFF1 signal is at a LOW
signal level, the time between a successful fault
acknowledgment and a new fault must be at least
1s.
For p1210 = 1, fault F07320 is not generated if the
acknowledge attempt failed (e.g. because the faults
occurred too frequently).
4 Automatic restart after line If p1210 = 4, an automatic restart will only be
supply failure, no additional start performed if fault F30003 also occurs on the Power
attempts Module or there is a HIGH signal at binector input
p1208[1]. If additional faults are present, then these
faults are also acknowledged and when successfully
acknowledged, the starting attempt is continued.
When the 24 V power supply of the CU fails, this is
interrupted as a line supply failure.
6 Restart after any fault with When p1210 = 6, an automatic restart is carried out
additional start attempts after any fault or when p1208[0] = 1. If the faults
occur one after the other, then the number of start
attempts is defined using p1211. Monitoring over
time can be set using p1213.

Starting attempts (p1211) and delay time (p1212)

p1211 is used to specify the number of starting attempts. The number is internally
decremented after each successful fault acknowledgment (line supply voltage must be re-
applied). Fault F07320 is signaled if the number of parameterized startup attempts is
exceeded.
When p1211 = x, x + 1 starting attempts are made.

Note
A start attempt immediately starts when the fault occurs.
The faults are automatically acknowledged in intervals of half the delay time p1212.
After successful acknowledgment and voltage recovery, the system is automatically powered
up again.

The starting attempt is considered to have been successfully completed once motor
magnetization (induction motor) is complete (r0056.4 = 1) and one additional second has
expired. The starting counter is only reset back to the initial value p1211 after this time.
If additional faults occur between successful acknowledgment and the end of the startup
attempt, then the startup counter, when it is acknowledged, is also decremented.

Monitoring time line supply return (p1213)

The monitoring time starts when the faults are detected. If the automatic acknowledgments
are not successful, the monitoring time runs again. If the drive has not successfully restarted
once the monitoring time has expired (motor magnetization must have been completed:
r0056.4 = 1), fault F07320 is output. The monitoring is deactivated with p1213 = 0.
If a fault is pending, fault F07320 will be generated on every restart attempt if the time
defined in p1213 has expired. If p1210 > 1 and the time in p1213 is set lower than p1212,
then fault F07320 will also be generated on every restart attempt. The monitoring time must
be extended if the faults that occur cannot be immediately and successfully acknowledged
(e.g. when faults are permanently present).

7.2.4 Armature short-circuit brake, DC brake

Features
● For permanent-magnet synchronous motors:
– Controlling an external armature short-circuit configuration
● For induction motors:
– Activation of DC brake
● Assignment as fault response

Description
Armature short-circuit braking is only supported for permanent-magnet synchronous motors.
It is mainly required when braking in a hazardous situation, if controlled braking using the
frequency converter is no longer possible (e.g. in the event of a power failure, EMERGENCY
OFF, etc.). The motor's stator windings are short-circuited by means of a contactor circuit
(possibly using external braking resistors). The resistance in the motor circuit suppresses the
motor's kinetic energy.
In order for the CU305 to be able to maintain this function in the event of a power failure, an
uninterruptible 24 V power supply (UPS) must be used. High-speed permanent-magnet
spindle drives for machine tools are a typical application for armature short-circuit braking.
With the external armature short-circuit brake, the slow contactor response causes a
response in the range of > 60 ms.
DC braking is only supported for induction motors. It can be used most effectively to bring
the rotor to a safe standstill in the event of the loss of the encoder signal. In order to achieve
this, a constant DC current is injected in the stator to decelerate the rotor to standstill and
hold it there.
The functions can be triggered by applying a "1" signal to binector input p1230 or in
response to a fault (see the description of p0491 or p2100/p2101).

External armature short-circuit braking

The external armature short-circuit is activated by setting p1231 = 1 (with contactor feedback
signal) or p1231 = 2 (without contactor feedback signal). It can be triggered via an input
signal p1230 (signal = 1) or a fault response. Triggering takes place once the pulses have
been suppressed or the circuit breaker has been inhibited.
This function uses output terminals to control an external contactor, which can short-circuit
the motor terminals via external resistors, for example. An armature short-circuit brake has
the advantage of a higher braking effect than a mechanical brake at the start of braking (at a
high speed). However, since the braking effect fades away as the speed drops, we
recommend a combination of armature and mechanical braking.
For the function with contactor feedback signal, you will need to wire the feedback inputs of
both command data sets (CDS = 2) p1235[0..1].
The external armature short-circuit is only supported for rotary-type permanent-magnet
synchronous motors (p0300 = 2xx).

Function Manual
Function Manual, 11/2009, 6SL3097-4AB10-0BP1 193
Drive functions
7.2 Basic functions

DC brake (induction motors)

The DC brake is activated by setting parameter p1231 = 4 (internal armature short-circuit/DC
brake). It can be triggered via an input signal p1230 (signal = 1) or a fault response:
Activation of DC brake with BI p1230
If the DC brake is activated with the digital input signal, the pulses will first be inhibited for
the motor demagnetization time p0347 in order to demagnetize the motor. Next, braking
current p1232 is injected into the DC brake for as long as the signal = 1 at the binector input,
in order to decelerate the motor or hold it at standstill.
When the DC brake is released, the drive will return to its initial operating mode (it is only at
this point that the motor is remagnetized).
In this mode, parameter p1234 (speed at the start of DC braking) is ignored.
DC brake as a fault response
If the DC brake is activated as a fault response, the motor will first be decelerated in field-
oriented mode along the OFF1 ramp (defined using p1082, p1121) until it reaches the speed
at the start of DC braking (p1234). If the fault in response to which braking has been
triggered is an encoder fault, braking will not be controlled (p1234 is ignored). Next, the
pulses will be inhibited for the motor demagnetization time p0347 in order to demagnetize
the motor. DC braking will then commence for the DC braking duration set in p1233. If an
encoder signal is available (neither encoder fault nor encoderless operation), the DC brake
will remain active for the set duration p1233 but will be deactivated at the latest when the
standstill threshold p1226 is undershot.

NOTICE
In encoderless operation or with strong field weakening in particular, when the rotor is
rotating, there is no guarantee of controlled operation being restored once the DC brake
function has been deactivated. In such cases, the drive will shut down with a fault message
with OFF2 response.

Note
• During parameterization, a check is made to determine whether the following conditions
have been met (if not, fault message F7906 is generated):
– Suitable type of motor for function
– Function-specific: Sensible assignment of parameters p1232 ... p1237.
• The internal armature short-circuit (p1231 = 4 for synchronous motor) and internal voltage
protection (p1231 = 3) functions are not supported for the SINAMICS S110 system.
• The "IASC/DC brake" fault response has the second-highest priority (second only to
OFF2).

7.2.5 OFF3 torque limits

Description
If the torque limits are externally specified (e.g. tension controller), then the drive can only be
stopped with a reduced torque.
In order to avoid this, there is a binector input (p1551), that for a LOW signal, activates the
torque limits p1520 and p1521. This means that the drive can brake with the maximum
torque by interconnecting the signal OFF 3 (r0899.5) to this binector.

7.2.6 Simple brake control

Features
● Automatic activation by means of sequence control
● Standstill (zero-speed) monitoring
● Forced brake release (p0855, p1215)
● Application of brake for a 1 signal "unconditionally close holding brake" (p0858)
● Application of brake after "Enable speed controller" signal has been canceled (p0856)

Description
The "Simple brake control" is used exclusively for the control of holding brakes. The holding
brake is used to secure drives against unwanted motion when deactivated.
The control command for opening and closing the holding brake is transferred directly to the
drive via by the Control Unit that logically links and monitors the signals with the system-
internal processes.
The Power Module then performs the action and activates the output for the holding brake.
The exact sequence control is illustrated in the SINAMICS S110 List Manual (FP 2701).
The operating principle of the holding brake can be configured via parameter p1215.

WARNING
The holding brake must not be used as a service brake.
When holding brakes are used, the special technological and machine-specific conditions
and standards for ensuring personnel and machine safety must be observed.
The risks involved with vertical axes, for example, must also be taken into account.

Commissioning
Simple brake control is activated automatically (p1215 = 1) when the Power Module has an
internal brake control and a connected brake has been found.
If no internal brake control is available, the control can be activated using a parameter
(p1215 = 3).

CAUTION
If p1215 = 0 (no brake available) is set when a brake is present, the drive runs with applied
brake. This can damage the brake beyond repair.

CAUTION
Brake control monitoring may only be activated for Blocksize power units with Safe Brake
Relay (p1278 = 0).

7.2.7 Parking axis and parking encoder

The parking function is used in two ways:
● "Parking axis"
– Monitoring of all encoders assigned to the "motor control" application of a drive is
suppressed.
– All encoders assigned to the "Motor control" application of a drive are prepared for the
"removed" state.
● "Parking encoder"
– Monitoring of a certain encoder is suppressed.
– The encoder is prepared for the "removed" state.

Parking an axis
When the axis is parked, the power unit and all the encoders assigned to "motor control" are
switched to inactive (r0146[n] = 0).
● Control is carried out via the control/status words of the cyclic telegram (STW2.7 and
ZSW2.7) or using parameters p0897 and r0896.0.
● The drive must be brought to a standstill by the higher-level controller (disable pulses e.g.
via STW1.0/OFF1).
● A measuring system that is not assigned to the "motor control" (e.g. direct measuring
system) remains active (r0146[n] = 1).
● The drive object remains active.

Note
Once the "Parking axis" / "Parking encoder" status has been canceled, you may have to
carry out the following actions:
If the motor encoder has been replaced: determine the commutation angle offset (p1990).
A new encoder must be referenced again (e.g. to determine the machine zero point).

Parking an encoder
When an encoder is parked, the encoder being addressed is switched to inactive (r0146 = 0).
● Control is carried out via the encoder control/status words of the cyclic telegram
(Gn_STW.14 and Gn_ZSW.14).
● With a parked motor measuring system, the associated drive must be brought to a
standstill by the higher-level control system (disable pulses e.g. via CTW1.0/OFF1).
● The monitoring functions for the power unit remain active (r0126 = 1).

7.2.8 Runtime (operating hours counter)

Total system runtime

The total system runtime is displayed in p2114 (Control Unit). Index 0 indicates the system
runtime in milliseconds after reaching 86.400.000 ms (24 hours), the value is reset. Index 1
indicates the system runtime in days.
At power-off the counter value is saved.
After the drive unit is powered-up, the counter continues to run with the value that was saved
the last time that the drive unit was powered-down.

Relative system runtime

The relative system runtime after the last POWER ON is displayed in p0969 (Control Unit).
The value is in milliseconds and the counter overflows after 49 days.

Actual motor operating hours

The motor operating hours counter p0650 (drive) is started when the pulses are enabled.
When the pulse enable is withdrawn, the counter is stopped and the value saved.
If p0651 is at 0, the counter is de-activated.
If the maintenance interval set in p0651 is reached, fault F01590 is triggered. Once the
motor has been maintained, the maintenance interval must be reset.

CAUTION
If the motor data set is switched during the star/delta switchover without the motor being
changed, the two values in p0650 must be added to determine the correct number of motor
operating hours.

Operating hours counter for the fan

The operating hours of the fan in the power unit are displayed in p0251 (drive).
The number of hours operated can only be reset to 0 in this parameter (e.g. after a fan has
been replaced). The service life of the fan is entered in p0252 (drive). Alarm A30042 is
output 500 hours before this figure is reached. Monitoring is deactivated when p0252 = 0.

7.2.9 Changing the direction of rotation without changing the setpoint

Features
● Not change to the speed setpoint and actual value, the torque setpoint and actual value
and the relative position change.
● Only possible when the pulses are inhibited

CAUTION
If a change of rotational direction is configured in the data set configurations (e.g.
p1821[0] = 0 and p1821[1] = 1), then when the function module basic positioner or
position control is activated, the absolute adjustment must be reset each time the
system boots or when the rotational direction changes (p2507), as the position
reference is lost when the rotational direction changes.

Note
If one of the p1959.14/15 options (positive/negative direction of rotation permitted) is
selected in parameter p1959, this will affect the direction of rotation when p1821 (sense of
rotation) is set as follows:
If p1821 = 0 or 1, positive direction of rotation (p1959.14 =1) means: clockwise or counter-
clockwise direction respectively.
If p1821 = 1 or 0, negative direction of rotation (p1959.15 =1) means: counter-clockwise or
clockwise direction respectively.

Description
The direction of rotation of the motor can be reversed using the rotational direction change
via p1821 without having to change the motor rotating field by interchanging two phases at
the motor and having to invert the encoder signals using p0410.
The rotational direction change via p1821 can be detected as a result of the direction of
rotation of the motor. The speed setpoint and actual value, torque setpoint and actual value
and also the relative position change remain unchanged.
The rotational direction change can be identified as a result of the phase voltage. Similarly,
when the rotational direction changes, the absolute position reference is also lost.

7.3.1 Function modules - Definition and commissioning

Description
A function module is a functional expansion of a drive object that can be activated during
commissioning.
Examples of function modules:
● Technology controller
● Setpoint channel
● Extended brake control
A function module generally has separate parameters and, in some cases, separate faults
and alarms too. These parameters and messages are only displayed when the function
module is active. An active function module also generally requires additional processing
time, which must be taken into account during configuration.

Commissioning with STARTER

In the STARTER commissioning screens, you can activate the function modules directly
(e.g. technology controller) or indirectly (activating the basic positioner automatically
activates position control, for example).

Commissioning via parameter (only with BOP20)

The function modules can be activated/deactivated using parameter p0108 of the Control
Unit (CU). The READY LED on the main component of the drive object can be made to flash
by means of parameter p0124 (CU).

7.3.2 Technology controller

7.3.2.1 Features
Simple control functions can be implemented with the technology controller, e.g.:
● Level control
● Dancer position/tension control
● Pressure control
● Flow control
● Simple closed-loop control without higher-level controller
The technology controller features:
● Separate fixed values
● Integrated motorized potentiometer
● Technology controller with:
– Two scalable setpoints
– Ramp-function generator in setpoint channel
– Filter for actual value and setpoint channel
– Two modes for derivative component injection
– Pre-control
– Output ramp with limits
– Scalable output signal

7.3.2.2 Description

Motorized potentiometer
This function is used to simulate an electromechanical potentiometer for setpoint input.
Separate binector inputs for higher (p2235) and lower (p2236) are used to adjust the input
setpoint: The potentiometer limits are defined within maximum (p2237) and minimum
(p2238) values. The setpoint input is routed to an internal ramp-function generator, for which
both a ramp-up (p2247) and a ramp-down (p2248) time, as well as an initial value (p2240)
can be defined. Initial rounding can be activated to fine-tune the setpoint, whereby the
acceleration of the setpoint is calculated as follows:
a = 0.0001· MAX[p2237; |p2238|] · 0.132
The connector output of the motorized potentiometer (r2250) can, for example, be used as a
setpoint for the technology controller. The motorized potentiometer requires the OFF1
enable for operation.

Drive functions
7.3 Function modules

Technology controller
Two scalable setpoints (p2255/ p2256) can be specified via two connector inputs (p2253/
p2254). A ramp-function generator in the setpoint channel can be used to define a ramp by
means of the ramp-up and ramp-down times (p2257/p2258). Both the setpoint and actual
value channels have access to a filter element with configurable time constants (p2261 and
p2265).
The proportional gain (p2280), integral time (p2285) and derivative-action time (p2274) can
be set in the following technology controller. The controller itself has access to two controller
type modes dependent upon p2263:
● PI controller with derivative component in actual value channel (p2263 = 0; factory
setting)
With this type of controller, changes to actual values caused by a change in the
disturbance variable will generate a stronger reaction from the final controlling element
(on account of the derivative component) . The effect of abrupt changes to setpoints (no
ramp) on the control process is tempered by the reaction of the final controlling element
(thereby reducing the load on the final controlling element). The derivative component
can also be used to compensate the delay generated by the upstream smoothing of a
noisy actual value signal.

Figure 7-35 Controller structure of the PI controller with derivative component in the actual value
channel

● Technology controller (p2263 = 1)

Here, the derivative component is generated from the system deviation; as such, a
setpoint change will generate an abrupt change in the final controlling element. Changes
to disturbance variables are also compensated more quickly due to the action of the
derivative component.

Please note that the controller structure of the technology controller differs from the standard
technology controller structure described below, which is standard in some sources. To
enable comparison, the corresponding conversions have been specified:

Figure 7-37 Technology controller structure with parallel components

where

Other controller variants are also possible:

● PI controller by switching out the derivative component (rate time TV: p2274 = 0)
● PD controller by switching out the integral component (integral time TN: p2285 = 0)
● Proportional controller by switching-out the integral and derivative components (p2274 = 0;
p2285 = 0)
Note:
In the factory setting (p2252.1 = 1), the integral component is not dependent upon the
proportional gain (p2280). In this case p2285 is the integration time constant TI. If p2252.1 = 0,
p2285 will become the integral time TN, with the result that the following applies for the integral
component:

A further connector input (p2289) is available at the controller output for pre-control or
switching in fault values. The signal is then routed via a limit (p2291/2).
The technology controller has a dedicated enable binector input (p2200). To avoid abrupt
changes in the output signal, an output ram can be defined by means of a ramp-up/ramp-
down time (p2293).
Note:
In the factory setting p2252.2 = 1, the output will be set to 0 as soon as the enable is lost
(p2200 = 0). In order for the output signal to be fed back via the output ramp, p2252.2 = 0
must be set.
The output signal (r2294) can then be scaled via the connector input p2295 before being
made available as a connector output for downstream connection.

7.3.3 Extended monitoring functions

7.3.3.1 Description
When the extension is activated, the monitoring functions are extended as follows:
● Speed setpoint monitoring: |n_setp| ≤ p2161
● Speed setpoint monitoring: n_set > 0
● Load monitoring

Description of load monitoring

This function monitors power transmission between the motor and the working machine.
Typical applications include V-belts, flat belts, or chains that loop around the belt pulleys or
cog wheels for drive and outgoing shafts and transfer the peripheral speeds and forces.
Load monitoring can be used here to identify blockages in the working machine and
interruptions to the power transmission.
During load monitoring, the current speed/torque curve is compared with the programmed
speed/torque curve (p2182 to p2190). If the current value is outside the programmed
tolerance bandwidth, a fault or alarm is triggered depending on parameter p2181. The fault
or alarm message can be delayed by means of parameter p2192 to prevent false messages
caused by brief transitional states.

● Via parameter p1215
● Via binectors p1219[0...3] and p0855
● Via zero speed detection
● Via a connector interconnection threshold value
For an AC drive with "Safe Brake Relay," the "Safe Brake Control" safety function requires
that the type of the brake control be set in parameter p1278, to "Brake control with diagnostic
evaluation" (p1278 = 0).

7.3.4.4 Examples

Starting against applied brake

When the device is switched on, the setpoint is enabled immediately (if other enable signals
are issued), even if the brake has not yet been released (p1152 = 1). The factory setting
p1152 = r0899.15 must be disconnected here. The drive first generates torque against the
applied brake. The brake is not released until the motor torque or motor current (p1220) has
exceeded braking threshold 1 (p1221).
This configuration is used, for example, when the drive is connected to a belt that is under
tension (loop accumulator in the steel industry).

Emergency brake
If emergency braking is required, electrical and mechanical braking is to take place
simultaneously. This can be achieved if OFF3 is used as a tripping signal for emergency
braking:
p1219[0] = r0898.2 (OFF3 to "apply brake immediately").
The OFF3 ramp (p1135) should be set to 0 seconds so that the converter does not work
against the brakes. Regenerative energy may accumulate, and this must be either fed back
into the supply system or converted into heat using a braking resistor.
This is often used, for example, in calendar stacks, cutting tools, running gears, and presses.

Operating brake for crane drives

For cranes with a manual control, it is important that the drive immediately response when
the control lever is moved (master switch). The drive is powered-up using the on command
(p0840) (the pulses are enabled). Speed setpoint (p1142) and speed controller (p0856) are
inhibited. The motor is magnetized. The magnetization time generally applicable for three-
phase motors (1-2 seconds) is therefore eliminated.
Now, there is only the brake opening time that is applicable as delay between moving the
master switch and the motor rotating. If the master switch is moved (deflected), then there is
a "setpoint enable from the control" (bit interconnected with p1142, p1229.2, p1224.0). The
speed controller is immediately enabled - the speed setpoint is enabled after the brake
opening time (p1216). When the master switch is in the zero position, the speed setpoint is
inhibited - the drive is ramp-down using the ramp function generator. The brake closes once
the standstill limit (p1226) has been fallen below. After the brake closing time (p1217), the
speed controller is inhibited (the motor is no longer generating any force). The extended
brake control is used with the modifications described below.

7.3.4.5 Commissioning
The extended brake control function can be activated while the commissioning Wizard is
running. Parameter r0108.14 indicates whether the function module has been activated.
Unless you change the default settings, the extended brake control function behaves in
exactly the same way as the simple brake control function.
Brake control can be activated via a parameter (p1215 = 3).
When braking with a feedback signal (p1222), the inverted signal must be connected to the
BICO input for the second (p1223) feedback signal. The response times of the brakes can
be set in p1216 and p1217.

Note
If p1215 = 0 (no brake available) is set when a brake is present, the drive runs with applied
brake. This can damage the brake beyond repair.

CAUTION
Brake control monitoring may only be activated for Blocksize power units with Safe Brake
Relay (p1278 = 0).

7.3.5 Closed-loop position control

7.3.5.1 General features

The position controller essentially comprises the following parts:
● Position actual value conditioning (including the lower-level measuring probe evaluation
and reference mark search)
● Position controller (including limits, adaptation and the pre-control calculation)
● Monitoring functions (including standstill, positioning, dynamic following error monitoring
and cam signals)
● There is still no position actual value conditioning for distance-coded measuring systems.
● Position tracking of the load gear (motor encoder), using absolute encoders for rotary
axes (modulo) as for linear axes.

7.3.5.2 Position actual value conditioning

Features
● Correction value (p2512, p2513)
● Setting value (p2514, p2515)
● Position offset (p2516)
● Position actual value (r2521)
● Velocity actual value (r2522)
● Motor revolutions (p2504)
● Load revolutions (p2505)
● Spindle pitch (p2506)
● Position tracking (p2720ff)

Description
The position actual value conditioning implements the conditioning of the position actual
value in a neutral position unit LU (LENGTH UNIT). To do this, the function block uses the
encoder evaluation/motor control with the available encoder interfaces Gn_XIST1,
Gn_XIST2, Gn_STW and Gn_ZSW. These just provide position information in encoder
pulses and fine resolution (increments).
The position actual value is conditioned immediately after the system has booted, regardless
of whether the position controller is enabled, as soon as valid values are received via the
encoder interface.
Parameter p2502 (encoder assignment) is used to define from which encoder (1 or 2), the
position actual value is sensed.

Figure 7-40 Position actual value sensing with rotary encoders

The link between the physical variables and the neutral length unit LU is established via
parameter p2506 (LU per load revolution) for rotary encoders. Parameter p2506 mirrors,
together with p2504, p2505, the interrelationship between encoder increments and the
neutral position unit LU.
Example:
Rotary encoder, ball screw with a pitch of 10 mm/revolution. 10 mm should have a resolution
of 1 µm (i.e. 1 LU = 1 µm).
→ One load revolution corresponds to 10000 LU
→ p2506 = 10000

Note
The effective actual value resolution is obtained from the product of the encoder pulses
(p0408) and the fine resolution (p0418).

Figure 7-42 Position actual value conditioning

A correction can be made using connector input p2513 (correction value, position actual
value conditioning) and a positive edge at binector input p2512 (activates the correction
value). When the "basic positioning" function module is activated, p2513 is automatically
interconnected with r2685 (EPOS correction value) and p2512 with r2684.7 (activate
correction). This interconnection enables modulo offset by EPOS, for example.
p2516 can be used to switch in position offset. Using EPOS, p2516 is automatically
interconnected to r2667. Backlash compensation is implemented using this interconnection.
Using the connector input p2515 (position setting value) and a "1" signal at binector input
p2514 (set position actual value), a position setting value can be entered.

WARNING
When the actual position value is set (p2514 = "1" signal), the actual position value of the
position controller is kept at the value of connector p2515 as standard.
Incoming encoder increments are not evaluated. A difference in position cannot be
compensated for in this situation.

An inversion of the actual position value resulting from the encoder is undertaken using
parameter p0410. An inversion of the axis motion can be entered using a negative value in
p2505.

Load gear position tracking

Terminology
● Encoder range
The encoder range is the position area that can itself represent the absolute encoder.
● Singleturn encoder
A singleturn encoder is a rotating absolute encoder, which provides an absolute image of
the position inside an encoder rotation.
● Multiturn encoder
A multiturn encoder is an absolute encoder that provides an absolute image of several
encoder revolutions (e.g. 4096 revolutions).

Description
Position tracking enables reproduction of the position of the load when gears are used. It can
also be used to extend the position area.
With position tracking, a load gear can also be monitored if the "position control" function
module is active (p0108.3 = 1).

Figure 7-43 Overview of gears and encoders

The encoder position actual value in r0483 (must be requested via GnSTW.13) is limited to
232 places. When position tracking is switched off (p2720.0 = 0), the encoder position actual
value r0483 comprises the following position information:
● Encoder pulses per revolution (p0408)
● Fine resolution per revolution (p0419)
● Number of resolvable revolutions of the rotary absolute encoder (p0421), this value is
fixed at "1" for singleturn encoders.
When position tracking is activated (p2720.0 = 1), the encoder position actual value r0483
comprises the following:
● Encoder pulses per revolution (p0408)
● Fine resolution per revolution (p0419)
● The gear ratio (p0433/p0432)

Prerequisite
● Absolute encoder

Description
Position tracking enables reproduction of the position of the load when gears are used. It can
also be used to extend the position area.
Position tracking is activated via parameter p2720.0 = 1. The position tracking of the load
gear, however, is only relevant for the motor encoder (encoder 1). The load gear ratio is
entered via parameters p2504 and p2505. Position tracking can be activated with rotary axes
(modulo).
Position tracking for the load gear can only be activated once for each motor data set MDS.
The load position actual value in r2723 (must be requested via GnSTW.13, see section
"Control and status words for encoders") comprises the following information:
● Encoder pulses per revolution (p0408)
● Fine resolution per revolution (p0419)
● Virtual number of stored revolutions of a rotary absolute encoder (p2721)
● Load gear ratio (p2504/p2505)

Note
The sum of p0408, p0419 and p2721 is limited to 32 bits.

Example of position area extension

With absolute encoders without position tracking, it must be ensured that the traversing
range is 0 smaller than half the encoder range, because beyond this range, no unique
reference remains after switching on and off (see description on parameter p2507). This
traversing range can be extended using the virtual multiturn (p2721).
The following diagram illustrates an absolute encoder that can represent 8 encoder
revolutions (p0421 = 8).

Figure 7-44 Position tracking (p2721 = 24), setting p2504 = p2505 =1 (gear factor = 1)

In this example, this means:

Without position tracking, the position for +/- 4 encoder revolutions about r2521 = 0 LU can
be reproduced.
With position tracking, the position for +/- 12 encoder revolutions (+/- 12 load revolutions with
load gear) can be reproduced (p2721 = 24).
Practical example:
For a linear axis, the value for p2721 is set to 262144 for an encoder with p0421 = 4096.
That means, +/- 131072 encoder revolutions or load revolutions can be reproduced in this
way.
For a rotary axis, a value for p2721 = p0421 is set for an encoder.

Configuration of the load gear (p2720).

The following points can be set by configuring this parameter:
● p2720.0: Activation of position tracking
● p2720.1: Setting the axis type (linear or rotary axis)
Here, a rotary axis refers to a modulo axis (modulo offset can be activated through
higher-level control or EPOS). With a linear axis, position tracking is mainly used to
extend the position area (see section: Virtual multiturn encoder (p2721)).
● p2720.2: Reset position
The position values stored in non-volatile memory are reset in response to the following
events:
– When encoder replacement is detected.
– When the configuration of the encoder data set (EDS) is modified.
– When the absolute encoder is adjusted again.

Note
If position tracking of the load gear is activated with parameter p2720[0]=1 (position gear
load tracking) after the encoder is adjusted (p2507=3), the adjustment will be reset.
If the encoder is adjusted again when load position tracking is active, the load gear position
will be reset (overflows).
The permissible position tracking range is mapped onto the reproducible encoder range of
EPOS.

Virtual multiturn encoder (p2721)

The virtual multiturn resolution is used to set the number of resolvable motor rotations for a
rotary absolute encoder with activated position tracking. It can be edited only for rotary axes.
With a rotary absolute encoder (p0404.1 = 1) with activated position tracking (p2720.0 = 1),
p2721 can be used to enter a virtual multiturn resolution.

Note
If the gear factor is not equal to 1, then p2721 always refers to the load side. The virtual
resolution, which is required for the load, is then set here.

For rotary axes, the virtual multiturn resolution (p2721) is preset to the value of the multiturn
resolution of the encoder (p0421) but may be changed.
Example: Singleturn encoder
Parameter p0421 is preset to p0421 = 1. However, parameter p2721 can be altered
subsequently, e.g. the user can program p2721 = 5. As a result, the encoder evaluation
initiates 5 load rotations before the same absolute value is achieved again.
For linear axes, the virtual multiturn resolution (p2721) is preset to the multiturn resolution of
the encoder (p0421) extended by 6 bits (max. overflows 32 positive/negative)
The value for p2721 cannot be edited again afterwards.
Example: Multiturn encoder
For a linear axis, the value for p2721 is set to 262144 for an encoder with p0421 = 4096.
That means, +/- 131072 encoder revolutions or load revolutions can be reproduced in this
way.
If, as a result of extension of the multiturn information, the displayable area of r2723 (32 bits)
is exceeded, the fine resolution (p0419) must be reduced accordingly.

 Drive functions
7.3 Function modules

Tolerance window (p2722)

After switching on, the difference between the stored position and the actual position is
ascertained and, depending on the result, the following is triggered:
Difference within the tolerance window → the position is reproduced based on the current
actual encoder value.
Difference outside the tolerance window → an appropriate message (F07449) is output.
The tolerance window is preset to quarter of the encoder range and can be changed.

CAUTION
The position can only be reproduced if, in the powered-down state, the encoder was moved
through less than half of the range that it can represent. For the standard EQN1325
encoder, this is 2048 revolutions or half a revolution for singleturn encoders.

Note
The ratio stamped on the gear rating plate is often just a rounded-off value (e.g.1:7.34). If, for
a rotary axis, it is not permissible to have any long-term drift, then the actual ratio of the
gearbox teeth must be requested from the gearbox manufacturer.

Multiple drive data sets

Position tracking of the load gear can be activated in multiple drive data sets.
● The load gear is DDS-dependent.
● Load gear position tracking is computed only for the active drive data set and is EDS-
dependent.
● The position tracking memory is only available once for each EDS.
● For position tracking to be continued in different drive data sets under the same
mechanical conditions and with the same encoder data sets, it must be activated
explicitly in all the relevant drive data sets. Possible applications of drive data set
switchover with continuation of position tracking:
– Star/delta switchover
– Different ramp-up times / controller settings
● When the switchover between drive data sets involves a change in gear unit, the position
tracking function starts from the beginning again, i.e. it behaves on switchover as if a
POWER ON had occurred.
● For identical mechanical relationships and the same encoder data set, DDS changeover
has no effect on the calibration status and reference point status.

Drive functions
7.3 Function modules

Restrictions
● Position tracking cannot be activated for an encoder data set which is used in different
drive data sets as encoder1 for different gears. If an attempt is still made to activate
position tracking, fault "F07555 (Drive encoder: Configuration position tracking" will be
displayed with fault value 03 hex.
A check is generally performed to determine whether the load gear is the same in all DDS
in which the relevant encoder data set is used.
In this case, the settings in each of the load gear parameters p2504[D], p2505[D],
p2720[D], p2721[D] and p2722[D] must be identical.
● If an encoder data set is used in one DDS as a motor encoder with position tracking and
in another DDS as an external encoder, the position tracking starts from the beginning
again, i.e. it behaves in the same way as it would do after a POWER ON.
● If position tracking is reset in one drive data set, it is also reset in all other drive data sets
which contain the relevant encoder data set.
● An axis in an inactive drive data set may move by a maximum of half an encoder range
(see p2722: tolerance window).

Commissioning position tracking load gear using STARTER

The position tracking function can be configured in the "Mechanical system" screen for
"Position control" in STARTER.
The "Mechanical system" screen for "Position control" is not made accessible unless the
function module "Basic positioner" is activated (r0108.4 = 1) which means that the function
module "Position control" (r0108.3 = 1) is automatically activated as well.
The "Basic positioner" function module can be activated via the commissioning wizard or the
drive configuration (configure DDS) (configuration "Closed-loop control structure" - checkbox
"Basic positioner").

Configuring the position tracking load gear function

The "Position tracking load gear" function can be configured in the following STARTER
screens:
1. In the "Mechanical system configuration" screen in the commissioning wizard.
2. In the project navigator under Drive → "Technology" → "Position control" in the
"Mechanical system" screen.

Description
The position controller is a PI controller. The P gain can be adapted using the product of

Figure 7-45 Zero-speed monitoring, positioning window

The position controller monitors the standstill, positioning and following error.
Zero-speed monitoring is activated by binector inputs p2551 (setpoint stationary) and p2542
(zero-speed window). If the zero-speed window is not reached once the monitoring time
(p2543) has lapsed, fault F07450 is triggered.
Positioning monitoring is activated via binector inputs p2551 (setpoint stationary), p2554 =
"0" (travel command not active) and p2544 (positioning window). Once the monitoring time
(p2545) has elapsed, the positioning window is checked once. If this is not reached, fault
F07451 is triggered.
The standstill monitoring and the positioning monitoring can be de-activated using the value
"0" in p2542 and p2544. The standstill window should be greater than or equal to the
positioning window (p2542 ≥ p2544). The standstill monitoring time should be less than or
equal to the positioning monitoring time (p2543 ≤ p2545).

7.3.5.5 Measuring probe evaluation and reference mark search

Description
The "Reference mark search" and "Measuring probe evaluation" functions can be initiated
and carried-out via binector input p2508 (activate reference mark search) and p2509
(activate measuring probe evaluation). Binector inputs p2510 (measurement probe selection)
and p2511 (measurement probe edge evaluation) define the mode for measurement probe
evaluation.
The probe signals are recorded via the encoder encoder status and control word. To speed
up signal processing, direct measuring probe evaluation can be activated by selecting the
input terminals for probes 1/2 via p2517 and p2518. Measuring probe evaluation is carried
out in the position controller cycle, whereby the set send clock cycle of the controller
(r2064[1]) must be an integer multiple of the position controller cycle.
The system outputs a message if the same probe input is already being used (see also
p0488, p0489 and p0580).
The appropriate function is started using a 0/1 edge at the appropriate input p2508 (activate
reference mark search) or p2509 (activate measuring probe evaluation) via the encoder
control word. Status bit r2526.1 (reference function) signals that the function is active
(feedback from the encoder status word). Status bit r2526.2 (measurement value valid)
shows the presence of the measurement required r2523 (position for reference mark or
measurement probe).
Once the function is complete (position determined for reference mark or measurement
probe), r2526.1 (reference function active) and r2526.2 (measurement valid) continue to
remain active and the measurement is provided by r2523 (reference measurement) until the
corresponding input p2508 (activate reference mark searches) or p2509 (activate
measurement probe evaluation) is reset (0 signal).
If the function (reference mark search or measuring probe evaluation) has still not been
completed and the corresponding input p2508 or p2509 is reset, then the function is
interrupted via the encoder control word and status bit r2526.1 (reference function active) is
reset via the encoder status word.
If both binector inputs p2508 and p2509 are simultaneously set, this causes the active
function to be interrupted and no function is started. This is indicated using alarm A07495
"reference function interrupted" and remains until the signals at the binector inputs are reset.
The alarm is also generated if, during an activated function (reference mark search or
measuring probe evaluation) a fault is signaled using the encoder status word.
If the "position control" function module is selected, these parameters (p2508 to p2511) are
preassigned with "0". If the "basic positioner" function module is selected, the functions
"reference mark search" (for the function reference point search) and "measuring probe
evaluation" (for the function flying referencing) are initiated by the function module basic
positioner and the feedback signal (r2526, r2523) is fed back to this (see also: section
"Control and status words for encoders").

7.3.5.6 Integration
The "positon control" function module is integrated in the system as follows:

Commissioning
The configuration screen for "Position control" in STARTER is not made accessible unless
the function module "Basic positioner" is activated (r0108.4 = 1) which means that the
function module "Position control" (r0108.3 = 1) is automatically activated as well.
The "basic positioner" function module can be activated via the commissioning wizard, drive
configuration ("configure DDS"); (configuration "Closed-loop control structure" - checkbox
"basic positioner").
To ensure correct, error-free operation of the basic positioner, it is absolutely essential that
the "Position control" function module is activated and the position control correctly
configured.
If the "position control" function module is active, and to optimize the speed controller, a
function generator signal is interconnected to the speed controller input p1160, then the
position controller monitoring functions respond. To prevent this from happening, the position
controller must be disabled (p2550 = 0) and switch to tracking mode (p2655 = 1, for control
using PROFIdrive telegram 110 PosSTW.0 = 1). In this way, the monitoring functions are
switched off and the position setpoint is tracked.

7.3.6 Basic Positioner

General description
The basic positioner is used to position linear and rotary axes (modulo) in absolute/relative
terms with motor encoder (indirect measuring system) or machine encoder (direct measuring
system).
User-friendly configuration, commissioning, and diagnostic functions are also available in
STARTER for the basic positioner functionality (graphic navigation). In STARTER, there is a
control panel for the basic positioner and speed-controlled operation; using this control
panel, the functionality can be started from a PC/PG to commission the system or carry out
diagnostics.
When the basic positioner is activated (r0108.4 = 1), then the position control (r0108.3 = 1)
should also be activated. This is realized automatically when activating the basic positioner
via the STARTER commissioning wizard. Further, the necessary "internal interconnections"
(BICO technology) are automatically established.

CAUTION
The basic positioner requires the position controller functions. The BICO interconnections
established by the basic positioner must be changed by experienced users only.

This means that naturally the position control functions are also available (e.g. standstill
monitoring, positioning monitoring, dynamic following error monitoring, cam controllers,
modulo function, measuring probe evaluation). Also refer to the section "Position control".
In addition, the following functions can be carried out using the basic positioner:
● Mechanical system
– Backlash compensation
– Modulo offset
– Position tracking of the load gear (motor encoder) with absolute encoders
● Limits
– Traversing profile limits
– Traversing range limits
– Jerk limitation

● Referencing or adjusting
– Set reference point (for an axis at standstill that has reached its target position)
– Reference point approach
(autonomous mode including reversing cam functionality, automatic direction of
rotation reversal, referencing to "cams and encoder zero mark" or only "encoder zero
mark" or "external equivalent zero mark (BERO)")
– Flying referencing
(during the "normal" traversing motion, it is possible to reference, superimposed, using
the measuring probe evaluation; generally, evaluating e.g. a BERO. Higher-level
(superimposed) function for the modes "jog", direct setpoint input/MDI and "traversing
blocks")
– Referencing with incremental measuring systems
– Absolute encoder adjustment
● Traversing blocks operating mode
– Positioning using traversing blocks that can be saved in the drive unit including block
change enable conditions and specific tasks for an axis that was previously referenced
– Traversing block editor using STARTER
– A traversing block contains the following information:
traversing block number
job (e.g. positioning, wait, GOTO block step, setting of binary outputs)
motion parameters (target position, velocity override for acceleration and deceleration)
mode (e.g: Skip block, block change enable conditions such as "Continue_with_stop"
and "Continue_flying")
Task parameters (e.g. delay time, block step conditions)
● Direct setpoint input (MDI) mode
– Positioning (absolute, relative) and setting-up (endless closed-loop position control)
using direct setpoint inputs (e.g. via the PLC or process data)
– It is always possible to influence the motion parameters during traversing (on-the-fly
setpoint acceptance) as well as on-the-fly change between the Setup and Positioning
modes.
● Jog mode
– Closed-loop position controlled traversing of the axis with the "endless position
controlled" or "jog incremental" modes that can be toggled between (traverse through
a "step width")
● Standard PROFIdrive positioning telegrams are available (telegrams 7, 9, 110 and 111).
When these are selected, the internal "connection" to the basic positioner is established
automatically.
● Control using PROFIdrive telegrams 7 and 110.

Figure 7-48 Backlash compensation

When mechanical force is transferred between a machine part and its drive, generally
backlash occurs. If the mechanical system was to be adjusted/designed so that there was
absolutely no play, this would result in high wear. Thus, backlash (play) can occur between
the machine component and the encoder. For axes with indirect position sensing,
mechanical backlash results in a falsification of the traversing distance, as, at direction
reversal, the axis travels either too far or not far enough corresponding to the absolute value
of the backlash.

Note
The backlash compensation is active, after
• the axis has been referenced for incremental measuring systems
• the axis has been adjusted for absolute measuring systems

In order to compensate the backlash, the determined backlash must be specified in p2583
with the correct polarity. At each direction of rotation reversal, the axis actual value is
corrected dependent on the actual traversing direction and displayed in r2667. This value is
taken into account in the position actual value using p2516 (position offset).
If a stationary axis is referenced by setting the reference point or an adjusted axis is
powered-up with an absolute encoder, then the setting of parameter p2604 (reference point
approach, starting direction) is relevant for switching-in the compensation value.

Figure 7-49 Modulo offset

A modulo axis has an unrestricted traversing range. The value range of the position repeats
itself after a specific value that can be parameterized (the modulo range or axis cycle), e.g.
after one revolution: 360° → 0°. The modulo range is set in parameter p2576, the offset is
activated with parameter p2577. The modulo offset is undertaken at the setpoint end. This is
provided with the correct sign via connector output r2685 (correction value) to appropriately
correct the position actual value. EPOS initiates the activation of the correction via a rising
edge of binector output r2684.7 (activate correction) (r2685 (correction value) and r2684.7
(activate correction) are already connected as standard with the corresponding
binector/connector input of the position actual value conditioning). Absolute positioning
details (e.g. in a traversing task) must always be within the modulo range. Modulo offset can
be activated for linear and rotary length units. The traversing range cannot be limited by a
software limit switch.
With active modulo offset and the application of absolute encoders, as a result of potential
encoder overflows, it must be ensured that there is an integer ratio v between the multiturn
resolution and the modulo range.
The ratio v can be calculated as follows:
● 1. Motor encoder without position tracking:
v = p0421 * p2506 * p0433 * p2505 / (p0432 * p2504 * p2576)
● 2. Motor encoder with position tracking for the load gear:
v = p2721 * p2506 * p0433 / (p0432 * p2576)
● 3. Motor encoder with position tracking for the load gear:
v = p2721 * p2506 / p2576
● 4. Direct encoder without position tracking:
v = p0421 * p2506 * p0433 / (p0432 * p2576)
With position tracking it is recommended to change p2721.

7.3.6.2 Limits

Description
The velocity, acceleration and deceleration can be limited and the software limit switches
and STOP cams set.

Features
● Traversing profile limits
– Maximum velocity (p2571)
– Maximum acceleration (p2572) / maximum deceleration (p2573)
● Traversing range limits
– Software limit switch (p2578, p2579, p2580, p2581, p2582)
– STOP cams (p2568, p2569, p2570)
● Jerk limitation
– Jerk limitation (p2574)
– Activation of jerk limitation (p2575)

Maximum velocity
The maximum velocity of an axis is defined using parameter p2571. The velocity should not
be set to be greater than the maximum speeds in r1084 and r1087.
The drive is limited to this velocity if a higher velocity is specified or programmed via the
override (p2646) for the reference point approach or is programmed in the traversing block.
Parameter p2571 (maximum velocity) defines the maximum traversing velocity in units 1000
LU/min. If the maximum velocity is changed, then this limits the velocity of a traversing task
that is presently being executed.
This limit is only effective in the positioning mode for:
● Jog mode
● Processing traversing blocks
● Direct setpoint input/MDI for positioning/setting-up
● Reference point approach

238 Function Manual, 11/2009, 6SL3097-4AB10-0BP1
 Drive functions
7.3 Function modules

Maximum acceleration/deceleration
Parameter p2572 (maximum acceleration) and p2573 (maximum deceleration) define the
maximum acceleration and the maximum deceleration. In both cases, the units are 1000 LU/s2.
Both values are relevant for:
● Jog mode
● Processing traversing blocks
● Direct setpoint input/MDI for positioning and setting-up
● Reference point approach
The parameters do not have any effect when faults occur with the fault responses OFF1 /
OFF2 / OFF3.
In the traversing blocks mode, the acceleration and deceleration can be set in multiple
integer steps (1 %, 2 % ... 100 %) of the maximum acceleration and deceleration. In “direct
setpoint input/MDI for positioning and setting up” operating mode, the acceleration/delay
override (assignment of 4000 hex = 100%) is specified

Note
A maximum acceleration and/or delay dependent on current velocity (zigzag acceleration) is
not supported.

Note
When using the PROFIdrive message frame 110, the velocity override is already connected
and has to be supplied by the message frame.

Software limit switches

The connector inputs p2578 (software limit switch minus) and p2579 (software limit switch
plus) limit the position setpoint if the following prerequisites are fulfilled:
● The software limit switches are activated (p2582 = "1")
● The reference point is set (r2684.11 = 1)
● The modulo correction is not active (p2577 = "0")
The connector inputs are, in the factory setting, linked to the connector output p2580
(software limit switch minus) and p2581 (software limit switch plus).

7.3 Function modules

STOP cam
A traversing range can, on one hand, be limited per software using the software limit
switches and on the other hand, the traversing range can be limited per hardware. In this
case, the functionality of the STOP cam (hardware limit switch) is used. The function of the
STOP cams is activated by the 1 signal on the binector input p2568 (activation of STOP
cams).
Once enabled, the activity of binector inputs p2569 (STOP cam, minus) and p2570 (STOP
cam, plus) is checked. These are low active; this means if a 0 signal is present at binector
input p2569 or p2570, then these are active.
When a STOP cam (p2569 or p2570) is active, the current motion is halted with the
maximum deceleration (p2573) and the appropriate status bit r2684.13 (STOP cam minus
active) or r2684.14 (STOP cam plus active) is set.
When an axis has approached a STOP cam, only motion that allows the axis to move away
from the cam is permitted (if both STOP cams are actuated, then no motion is possible).
When the STOP cam is exited, this is identified by the 0/1 edge in the permitted traversing
direction which means that the corresponding status bits (r2684.13 or r2684.14) are reset.

Jerk limitation
Acceleration and deceleration can change suddenly if jerk limiting has not been activated.
The diagram below shows the traversing profile when jerk limitation has not been activated.
The diagram shows that maximum acceleration (amax) and deceleration (dmax) are effective
immediately. The drive accelerates until the target speed (vtarget) is reached and then
switches to the constant velocity phase.

Figure 7-51 Activated jerk limitation

The maximum inclination (rk) can be set in parameter p2574 ("Jerk limitation") in the unit
LU/s3 for both acceleration and braking. The resolution is 1000 LU/s3. To activate limiting
permanently, set parameter p2575 ("Active jerk limitation") to 1. In this case, limitation
cannot be activated or deactivated in traversing block mode by means of the command
"JERK" as this would require parameter p2575 ("Activate jerk limitation") to be set to zero.
The status signal r2684.6 ("Jerk limitation active") indicates whether or not jerk limitation is
active.
Limitation is effective:
● In jog mode
● When traversing blocks are processed
● When setpoints are defined directly/MDI for positioning and setup
● During referencing
● During stop responses due to alarms
Jerk limitation is not active when messages are generated with stop responses OFF1 / OFF2 /
OFF3.

7.3.6.3 Referencing

Features
● Reference point offset (p2600)
● Reversing cams (p2613, p2614)
● Reference cam (p2612)
● Binector input start (p2595)
● Binector input setting (p2596)
● Velocity override (p2646)
● Reference point coordinate (p2598, p2599)
● Selecting the referencing type (p2597)
● Absolute encoder adjustment (p2507)

NOTICE
Referencing distance-coded zero marks is not supported.

Description
After a machine has been powered-up, for positioning, the absolute dimension reference
must be established to the machine zero. This operation is known as referencing.
The following referencing types are possible:
● Setting the reference point (all encoder types)
● Incremental encoder
Active referencing (reference point approach (p2597 = 0)):
– Reference cams and encoder zero mark (p2607 = 1)
– Encoder zero mark (p0495 = 0)
– External zero mark (p0495 ≠ 0)
● Flying referencing (passive (p2597 = 1))
● Absolute encoder
– Absolute encoder adjustment
– Flying referencing (passive (p2597 = 1))
A connector input is provided for all referencing types to input the reference point coordinate;
this allows, e.g. the change/input via the higher-level control. However, to permanently enter
the reference point coordinate, an adjustable parameter for this quantity is also required.
As standard, this adjustable parameter p2599 is interconnected to connector input p2598.

Set reference point

The reference point can be set using a 0/1 edge at binector input p2596 (set reference point)
if no traversing commands are active and the actual position value is valid (p2658 = 1
signal).
A reference point can also be set in conjunction with an intermediate stop.
The current actual position of the drive is set here as the reference point using the
coordinates specified by connector input p2598 (reference point coordinates). The setpoint
(r2665) is adjusted accordingly.
This function also uses actual position value correction for the position controller (p2512 and
p2513). Connector input p2598 is connected to adjustable parameter p2599 as standard.
The binector input is not effective for the traversing task being presently executed.

Absolute encoder adjustment

Absolute encoders must be adjusted while commissioning. After the machine has been
powered-down the position information of the encoder is kept.
When p2507 = 2 is entered, using the reference point coordinate in p2599, an offset value
(p2525) is determined. This is used to calculate the position actual value (r2521). Parameter
p2507 signals the adjustment with a "3" - in addition bit r2684.11 (reference point set) is set
to "1".
The offset of the encoder adjustment (p2525) should be saved in a non-volatile fashion
(RAM to ROM) to permanently save it.

Note
If an adjustment is lost on an already adjusted axis, the axis will remain unadjusted even
when the drive unit is switched OFF/ON. The axis needs to be adjusted again in such cases.

CAUTION
During adjustment with the rotary absolute encoder, a range is aligned symmetrically
around the zero point with half the encoder range within which the position is restored after
switch off/on. If position tracking is deactivated (2720.0 = 0), only one encoder overflow is
permitted in this range (further details are given in the chapter titled Position controller →
Position actual value conditioning). Once adjustment has been carried out, the range must
not be exited because a unique reference between the actual encoder value and the
mechanical components cannot be established outside the range.
If the reference point p2599 is in the encoder range, the actual position value is set in line
with the reference point during adjustment. Otherwise, it is set to a corrected value in the
encoder range.
No overflow occurs with linear absolute encoders, which means that the position can be
restored within the entire traversing range after switch on/off once adjustment has been
carried out. During adjustment, the actual position value is set in line with the reference
point.

Reference point approach for incremental measurement systems

When the reference point approach (in the case of an incremental measuring system), the
drive is moved to its reference point. In so doing, the drive itself controls and monitors the
complete referencing cycle.
Incremental measuring systems require that after the machine has been powered-up, the
absolute dimension reference is established to the machine zero point. When powering-up
the position actual value x0 in the non-referenced state is set to x0 = 0. Using the reference
point approach, the drive can be reproducibly moved to its reference point. The geometry
with a positive starting direction (p2604 = "0") is shown in the following.

binector input p2597 (referencing type selection). The signal in binector input p2595 (start
referencing) must be set during the entire referencing process otherwise the process is
aborted. Once started, the status signal r2684.11 (reference point set) is reset.
The software limit switch monitoring is inactive during the complete reference point
approach; only the maximum traversing range is checked. The SW limit switch monitoring is,
if required, re-activated after completion.
The velocity override set is only effective during the search for the reference cam (step 1).
This ensures that the "cam end" and "zero mark" positions are always overrun at the same
speed. If signal propagation delays arise during switching processes, this ensures that the
offset caused during establishment of position is the same in each referencing process.
Axes that only have one zero mark over their complete traversing or modulo range are
designated with parameter p2607 = 0 (no reference cam present). After starting the
referencing process, synchronization to the reference zero marks is started straight away
(see step 2) for these axes.

Search for reference, step 1: travel to reference cam

If there is no reference cam present (p2607 = 0), go to step 2.
When the referencing process is started, the drive accelerates at maximum acceleration
(p2572) to the reference cam approach velocity (p2605). The direction of the approach is
determined by the signal of binector input p2604 (search for reference start direction).
When the reference cam is reached, this is communicated to the drive using the signal at
binector input p2612 (reference cam); the drive then brakes down to standstill with the
maximum deceleration (p2573).
If a signal at binector input p2613 (reversing cam, MINUS) or at binector input p2614
(reversing cam, PLUS) is detected during reference point approach, the search direction is
reversed.
If the minus reversing cam is approached in the positive direction of travel or the plus
reversing cam in the negative direction of travel, fault message F07499 "EPOS: Reversing
cam approached from the wrong direction" is generated. In this case, the reversing cam
connections must be checked (BI: p2613, BI: p2614) or the direction of approach to the
reversing cam.
The reversing cams are low active. If both reversing cams are active (p2613 = "0" and p2614
= "0"), the drive remains stationary. As soon as the reference cam is found, then
synchronization to the reference zero mark is immediately started (refer to step 2).
If the axis leaves its start position and travels the distance defined in parameter p2606 (max.
distance to reference cam) heading towards the reference cam without actually reaching the
reference cam, the drive remains stationary and fault F07458 (reference cam not found) is
issued.
If the axis is already located at the cam, when referencing is started, then traversing to the
reference cam is not executed, but synchronization to the reference zero mark is
immediately started (refer to step 2).

Note
The velocity override is effective during the search for the cam. By changing the encoder
data set, status signal r2684.11 (reference point set) is reset.
The cam switch must be able to delivery both a rising and a falling edge. For a reference
point approach with evaluation of the encoder zero mark, for increasing position actual
values the 0/1 edge is evaluated and for decreasing position actual values, the 1/0 edge.
Inversion of the edge evaluation is not possible at the sensor zero mark.
If the length measuring system has several zero marks which repeat at cyclic intervals (e.g.
incremental, rotary measuring system), you must ensure that the cam is adjusted so that the
same zero mark is always evaluated.
The following factors may impact the behavior of the "reference cam" control signal:
• Switching accuracy and time delay of reference cam switch
• Position controller cycle of drive
• Interpolation cycle of drive
• Temperature sensitivity of machine’s mechanical system

Search for reference, step 2: Synchronizing to the reference zero mark

(encoder zero mark or external zero mark)
Reference cam available (p2607 = 1):
In step 2, the drive accelerates to the velocity, specified in p2608 (zero mark approach
velocity) in the direction opposite to that specified using binector input p2604 (reference point
approach start direction). The zero mark is expected at distance p2609 (max. distance to
zero mark). The search for the zero mark is active (status bit r2684.0 = "1" (search for
reference active)) as soon as the drive leaves the cam (p2612 = "0") and is within the
tolerance band for evaluation (p2609 - p2610). If the position of the zero mark is known
(encoder evaluation), the actual position of the drive can be synchronized using the zero
mark. The drive starts the search for reference (see step 3). The distance moved between
the end of the cam and the zero mark is displayed in diagnostics parameter r2680
(difference between the cam - zero mark).
Encoder zero mark available (p0495 = 0), no reference cam (p2607 = 0):
Synchronization to the reference zero mark begins as soon as the signal at binector input
p2595 (start referencing) is detected. The drive accelerates to the velocity, specified in
parameter p2608 (zero mark approach velocity) in the direction specified by the signal of
binector input p2604 (reference point approach start direction).
The drive synchronizes to the first zero mark and then starts to travel towards the reference
point (see step 3).

Note
In this case the direction of approach to the reference zero mark is the opposite to the axes
with reference cams!

External zero mark present (p0495 ≠ 0), no reference cam (p2607 = 0):
Synchronization to an external zero mark begins as soon as the signal at binector input
p2595 (start referencing) is detected. The drive accelerates to the velocity, specified in
parameter p2608 (zero mark approach velocity) in the direction specified by the signal of
binector input p2604 (reference point approach start direction). The drive synchronizes to the
first external zero mark (p0495). The drive continues to travel with the same velocity and
travel is started to the reference point (refer to step 3).

Note
The velocity override is inoperative during this process.
An equivalent zero mark can be set using parameter p0495 (equivalent zero mark input
terminal) and the corresponding digital input selected. As standard, for increasing actual
position values, the 0/1 edge is evaluated and for decreasing position actual values, the 1/0
edge. For the equivalent zero mark, this can be inverted using parameter p0490 (invert
measuring probe or equivalent zero mark).

Search for reference, step 3: Travel to reference point

Travel to the reference point is started when the drive has successfully synchronized to the
reference zero mark (see step 2). Once the reference zero mark has been detected, the
drive accelerates on-the-fly to the reference point approach velocity set in parameter p2611.
The reference point offset (p2600), the distance between the zero mark and reference point,
is extended.
If the axis has reached the reference point, then the position actual value and setpoint are
set to the value specified using connector input p2598 (reference point coordinate) (as
standard, connector input p2598 is connected with adjustable parameter p2599). The axis is
then homed and the status signal r2684.11 (reference point set) set.

Note
The velocity override is inoperative during this process.
If the braking distance is longer than the reference point offset or a direction reversal is
required as a result of the selected reference point offset, then after detecting the reference
zero mark, the drive initially brakes to standstill and then travels back.

Flying referencing
The mode "flying referencing" (also known as post-referencing, positioning monitoring),
which is selected using a "1" signal at binector input p2597 (select referencing type), can be
used in every mode (jog, traversing block and direct setpoint input for positioning/setting-up)
and is superimposed on the currently active mode. Flying referencing can be selected both
with incremental and absolute measuring systems.
When "flying referencing" during incremental positioning (relative) you can select whether
the offset value is to be taken into account for the travel path or not (p2603).
The "flying referencing" is activated by a 0/1 edge at binector input p2595 (start referencing).
The signal in binector input p2595 (start referencing) must be set during the entire
referencing process otherwise the process is aborted.
Status bit r2684.1 (passive/flying referencing active) is linked with binector input p2509
(activate measurement probe evaluation). It activates measurement probe evaluation.
Binector inputs p2510 (measurement probe selection) and p2511 (measurement probe edge
evaluation) can be used to set which measurement probe (1 or 2) and which measurement
edge (0/1 or 1/0) is to be used.

The measurement probe pulse is used to supply connector input p2660 (home measurement
value) with the measurement via parameter r2523. The validity of the measurement is
reported to binector input p2661 (measurement valid feedback) via r2526.2.

Note
The following must always apply to the "Flying referencing mode" windows:
p2602 (outer window) > p2601 (inner window).
See function diagram 3614 for more information on the "Flying referencing mode" function.

The following then happens:

● If the drive has not yet been homed, status bit r2684.11 (reference point set) is set to "1".
● If the drive has already been homed, status bit r2684.11 (reference point set) is not reset
when starting flying referencing.
● If the drive has already been homed and the position difference is less than the inner
window (p2601), the old actual position value is retained.
● If the drive has already been homed and the position difference is more than the outer
window (p2602), warning A07489 (reference point offset outside window 2) is output and
the status bit r2684.3 (pressure mark outside window 2) set. No offset to the actual
position value is undertaken.
● If the drive has already been referenced and the absolute value of the position difference
is greater than the inner window (p2601) and less the outer window (p2602), then the
position actual value is corrected.

Note
Flying referencing is not an active operating mode. It is superimposed by an active operating
mode.
In contrast to searches for reference, flying referencing can be carried out superimposed by
the machine process.
As standard, for flying referencing, measuring probe evaluation is used; when enabled, the
measuring probe is selected (p2510) and the edge evaluation (p2511) (in the factory setting,
measuring probe 1 is always the measuring probe, flank evaluation in the factory setting is
always the 0/1 edge).

Instructions for switching data sets

In the following cases, when a DDS switch takes place, the current actual position value
becomes invalid (p2521 = 0) and the reference point (r2684.11 = 0) is reset.
● The EDS that is effective for the position control changes.
● The encoder assignment changes (p2502).
● The mechanical relationships change (p2503...p2506)
With absolute encoders, the status of the adjustment (p2507) is also reset, if the same
absolute encoder is selected for the position control although the mechanical relationships
have changed (p2503 ... p2506).
In operating mode, a fault message (F07494) is also generated.

7.3.6.4 Referencing with more than one zero mark per revolution
The drive detects several zero marks per revolution when using reduction gears or
measuring gears. In this cases, an additional BERO signal allows the correct zero mark to be
selected.

Motor
4:1

Position Encoder

Zero mark

Figure 7-53 Design with a gear between the motor and spindle

The diagram shows an application example for referencing with several zero marks per
revolution and selecting the correct zero mark using a BERO signal.
By using a reduction gear between the motor and the load (spindle), the drive detects
several revolutions of the motor per mechanical revolution of the load - and therefore also
several encoder zero marks.
The higher-level control/position control when referencing requires a unique reference
between the encoder zero mark and the machine axis (load/spindle). This is the reason that
the "correct" zero mark is selected using a BERO signal.

Requirements
● The position of the zero mark that has the shortest distance to the position when the
BERO signal switches is to be determined.
● The appropriate mechanical preconditions must be fulfilled when mounting the BERO.
● The preferred mechanical configuration is that the BERO signal covers the zero mark as,
in this case, the zero mark selection is independent of the direction of rotation.
● In order to be able to precisely determine the position of the BERO (in relation to the
reference position of the encoder) even at higher speeds, this must be connected to a
fast Control Unit input.

7.3 Function modules

Evaluating the BERO signal

You have the option of either evaluating the positive or negative signal edge of the BERO signal:
● Positive edge (factory setting)
For referencing with a positive evaluation of the BERO signal, the encoder interface
supplies the position of the reference mark, which is directly detected after the positive
edge of the BERO signal. If, mechanically, the BERO is sized in such a way that the
BERO signal covers the entire width of the encoder zero mark, the required encoder zero
mark will be reliably detected in both traversing directions.
● Negative edge
For referencing with a negative edge evaluation of the BERO signal, synchronization is
realized to the next reference mark after leaving the BERO signal.
Proceed as follows to parameterize referencing with several zero marks:
● Using parameter p0493, define the fast digital input to which the BERO is connected.
● Set the corresponding bit of parameter p0490 to 1: The signal inversion means that the
evaluation uses the negative edge of the BERO signal.
Referencing then proceeds as follows:
● Via the PROFIdrive encoder interface, SINAMICS S receives the request for a reference
mark search.
● Using the parameterization, SINAMICS S determines the zero mark depending on the
BERO signal.
● SINAMICS S provides the (possibly corrected) zero mark position as reference mark via
the PROFIdrive encoder interface.

Note
At high speeds or if the distance between the BERO signal and the following zero mark is
too low, then it is possible that the required, next zero mark is not detected, but instead, a
subsequent one due to the computation time. Due to the known zero mark distance, in
this particular case, the determined position is correspondingly corrected.
When using a measuring gear, the zero mark position depends on the motor revolution.
In this case, a correction is also performed and for each motor revolution a reverse
calculation is made back to the position of the zero mark with the shortest distance BERO
signal ↔ zero mark.

7.3.6.5 Traversing blocks

Description
Up to 16 different traversing blocks can be saved. The maximum number is set using
parameter p2615 (maximum number of traversing tasks). All parameters which describe a
traversing order are effective during a block change, i.e. if:
● The appropriate traversing block number is selected using binector inputs p2625 to
p2630 (block selection, bits 0...5) and started using the signal at binector input p2531
(activate traversing task).
● A block change is made in a sequence of traversing tasks.
● An external block change p2632 "External block change" is triggered.
Traversing blocks are parameterized using parameter sets that have a fixed structure:
● Traversing block number (p2616[0...63])
Every traversing block must be assigned a traversing block number (in STARTER "No.").
The traversing blocks are executed in the sequence of the traversing block numbers.
Numbers containing the value "-1" are ignored so that the space can be reserved for
subsequent traversing blocks, for example.
You can use traversing block numbers in the range from 0 ... 63, regardless of the
maximum number of traversing blocks (= 16).
● Task (p2621[0...9])
1: POSITIONING
2: FIXED ENDSTOP
3: ENDLESS_POS
4: ENDLESS_NEG
5: WAIT
6: GOTO
7: SET_O

● Motion parameters
– Target position or traversing distance (p2617[0...63])
– Velocity (p2618[0...63])
– Acceleration override (p2619[0...63])

● Task mode (p2623[0...63])

The execution of a traversing task can be influenced by parameter p2623 (task mode).
This is automatically written by programming the traversing blocks in STARTER.
Value = 0000 cccc bbbb aaaa
– aaaa: Display/hide
0000: Block is not hidden
0001: Block is hidden
A hidden block cannot be selected binary-coded via binector inputs p2625 to p2630.
An alarm is output if you attempt to do so.
– bbbb: Continuation condition
0000, END: 0/1 edge at p2631
0001, CONTINUE_WITH_STOP:
The exact position parameterized in the block is approached (brake to standstill and
positioning window monitoring) before block processing can continue.
0010, CONTINUE_ON-THE-FLY:
The system switches to the next traversing block "on the fly" when the braking point
for the current block is reached (if the direction needs to be changed, this does not
occur until the drive stops within the positioning window).
0011, CONTINUE_EXTERNAL:
Same as "CONTINUE_ON-THE-FLY", except that an instant block change can be
triggered up to the braking point by a 0/1 edge. The 0/1 edge can be connected to
parameter r2526.2 of the "position control" function module, via the binector input
p2633 with p2632 = 1, or via the measuring input p2661 with p2632 = 0. Position
detection via the measuring input can be used as an accurate starting position for
relative positioning. If an external block change is not triggered, a block change is
triggered at the braking point.
0100, CONTINUE_EXTERNAL_WAIT
Control signal "External block change" can be used to trigger a flying changeover to
the next task at any time during the traveling phase. If "External block change" is not
triggered, the axis remains in the parameterized target position until the signal is
issued. The difference here is that with CONTINUE_EXTERNAL, a flying changeover
is carried out at the braking point if "External block change" has not been triggered,
while here the drive waits for the signal in the target position.
0101, CONTINUE_EXTERNAL_ALARM
This is the same as CONTINUE_EXTERNAL_WAIT, except that alarm A07463
"External traversing block change in traversing block x not requested" is output when
"External block change" is not triggered by the time the drive comes to a standstill.
The alarm can be converted to a fault with a stop response so that block processing
can be aborted if the control signal is not issued.
– cccc: Positioning mode
With the POSITION task (p2621 = 1), defines how the position specified in the
traversing task is to be approached.
0000, ABSOLUTE:
The position specified in p2617 is approached.
0001, RELATIVE:
The axis is traveled along the value specified in p2617.
0010, ABS_POS:
For rotary axes with modulo offset only. The position specified in p2617 is approached
in a positive direction.
0011, ABS_NEG:
For rotary axes with modulo offset only. The position specified in p2617 is approached
in a negative direction.

Accepting traversing blocks

You can transfer traversing blocks from one SINAMICS S110 to another. To do this, proceed
as follows:

Note
It is possible to accept traversing blocks from other SINAMICS devices. SINAMICS S110,
however, only imports the first 16 traversing blocks; any additional traversing blocks are
declined at the time of the import and a fault message is generated.

1. Select Project → Save and export from the STARTER menu on the source device and
define the export options.
2. If you do not want to accept certain traversing blocks, you can delete these from the
ISymbol.xml file using a suitable editing program.
3. Select Project → Import from the STARTER menu on the target device and choose the
XML file to be imported.

Intermediate stop and reject traversing task

The intermediate stop is activated by a 0 signal at p2640. After activation, the system brakes
with the parameterized deceleration value (p2620 or p2645).
The current traversing task can be rejected by a 0 signal at p2641. After activation, the
system brakes with the maximum deceleration (p2573).
The "intermediate stop" and "reject traversing task" functions are only effective in "traversing
blocks" and "direct setpoint input/MDI" modes.

POSITIONING
The POSITIONING task initiates motion. The following parameters are evaluated:
● p2616[x] Block number
● p2617[x] Position
● p2618[x] Velocity
● p2619[x] Acceleration override
● p2620[x] Deceleration override
● p2623[x] Task mode
The task is executed until the target position is reached. If, when the task is activated, the
drive is already located at the target position, then for the block change enable
(CONTINUE_ON-THE-FLY or CONTINUE_EXTERNAL, the text task is selected in the same
interpolation clock cycle. For CONTINUE_WITH_STOP, the next block is activated in the
next interpolation clock cycle. CONTINUE_EXTERNAL_ALARM causes a message to be
output immediately.

FIXED STOP
The FIXED STOP task triggers a traversing movement with reduced torque to fixed stop.
The following parameters are relevant:
● p2616[x] Block number
● p2617[x] Position
● p2618[x] Velocity
● p2619[x] Acceleration override
● p2620[x] Deceleration override
● p2623[x] Task mode
● p2622[x] Clamping torque [0.01 Nm] task parameter for rotary motors.
Possible continuation conditions include END, CONTINUE_WITH_STOP,
CONTINUE_EXTERNAL, CONTINUE_EXTERNAL_WAIT.

ENDLESS POS, ENDLESS NEG

Using these tasks, the axis is accelerated to the specified velocity and is moved, until:
● A software limit switch is reached.
● A STOP cam signal has been issued.
● The traversing range limit is reached.
● Motion is interrupted by the control signal "no intermediate stop/intermediate stop
(p2640).
● Motion is interrupted by the control signal "do not reject traversing task/reject traversing
task" (p2641).
● An external block change is triggered (with the appropriate continuation condition).
The following parameters are relevant:
● p2616[x] Block number
● p2618[x] Velocity
● p2619[x] Acceleration override
● p2623[x] Task mode
All continuation conditions are possible.

JERK
Jerk limitation can be activated (command parameter = 1) or deactivated (task parameter = 0)
by means of the JERK task. The signal at the binector input p2575 "Active jerk limitation" must
be set to zero. The value parameterized in "jerk limit" p2574 is the jerk limit.
A precise stop is always carried out here regardless of the parameterized continuation
condition of the task preceding the JERK task.
The following parameters are relevant:
● p2616[x] Block number
● p2622[x] Task parameter = 0 or 1
All continuation conditions are possible.

WAITING
The WAIT order can be used to set a waiting period, which should expire before the
following order is processed.
The following parameters are relevant:
● p2616[x] Block number
● p2622[x]Task parameter = delay time in milliseconds ≥ 0 ms
● p2623[x] Task mode
The delay time is entered in milliseconds - but is rounded-off to a multiple of the interpolator
clock cycle p0112[5]. The minimum delay time is one interpolation clock cycle; this means
that if a delay time is parameterized which is less than an interpolation clock cycle, then the
system waits for one interpolation clock cycle.
Example:
Wait time: 9 ms
Interpolation clock cycle: 4 ms
Active delay time: 12 ms
A precise stop is always carried out here before the wait time, regardless of the
parameterized continuation condition of the order preceding the WAIT order. The WAIT task
can be executed by an external block change.
Possible continuation conditions include END, CONTINUE_WITH_STOP,
CONTINUE_EXTERNAL, CONTINUE_EXTERNAL_WAIT, and
CONTINUE_EXTERNAL_ALARM. The fault message is triggered when "External block
change" has still not been issued after the delay time has elapsed.

GOTO
Using the GOTO task, jumps can be executed within a sequence of traversing tasks. The
block number which is to be jumped to must be specified as task parameter. A continuation
condition is not permissible. If there is a block with this number, then alarm A07468 (jump
destination does not exist in traversing block x) is output and the block is designated as
being inconsistent.
The following parameters are relevant:
● p2616[x] Block number
● p2622[x] Task parameter = Next traversing block number
Any two of the SET_O, RESET_O and GOTO orders can be processed in an interpolation
cycle and a subsequent POSITION and WAIT order can be started.

SET_O, RESET_O
Tasks SET_O and RESET_O allow up to two binary signals (output 1 or 2) to be
simultaneously set or reset. The number of the output (1 or 2) is specified bit-coded in the
task parameter.
The following parameters are relevant:
● p2616[x] Block number
● p2622[x] Task parameter = bit-coded output:
0x1: Output 1
0x2: Output 2
0x3: Output 1 + 2
Possible continuation conditions are END, CONTINUE_ON-THE-FLY and
CONTINUE_WITH_STOP, and CONTINUE_EXTERNAL_WAIT.
The binary signals (r2683.10 (output 1) (or r2683.11 (output 2)) can be assigned to digital
outputs. The assignment in STARTER is made using the button "configuration digital output".
Any two of the SET_O, RESET_O and GOTO orders can be processed in an interpolation

7.3.6.6 Travel to fixed stop

Description
The "Travel to fixed stop" function can be used, for example, to traverse sleeves to a fixed
stop against the workpiece with a predefined torque. In this way, the workpiece can be
securely clamped. The clamping torque can be parameterized in the traversing task (p2622).
An adjustable monitoring window for travek to fixed stop prevents the drive from traveling
beyond the window if the fixed stop should break away.
In positioning mode, travel to fixed stop is started when a traversing block is processed with
the FIXED STOP command. In this traversing block, in addition to the specification of the
dynamic parameterized position, speed, acceleration override and deceleration override, the
required clamping torque can be specified as task parameter p2622. From the start position
onwards, the target position is approached with the parameterized speed. The fixed stop (the
workpiece) must be between the start position and the braking point of the axis; that is, the
target position is placed inside the workpiece. The preset torque limit is effective from the
start, i.e. travel to fixed stop also occurs with a reduced torque. The preset acceleration and
deceleration overrides and the current speed override are also effective. Dynamic following
error monitoring (p2546) in the position controller is not effective when traveling to the fixed
stop. As long as the drive travels to the fixed stop or is in fixed stop, the "Travel to fixed stop
active" status bit r2683.14 is active.

Fixed stop is reached

As soon as the axis comes into contact with the mechanical fixed stop, the closedloop
control in the drive raises the torque so that the axis can move on. The torque increases up
to the value specified in the task and then remains constant. Depending on the binector input
p2637 (fixed stop reached), the "fixed stop reached" status bit r2683.12 is set if:
● the following error exceeds the value set in parameter p2634 (fixed stop: maximum
following error) (p2637 = r2526.4)
● external status via the signal at binector input p2637 (fixed stop reached), if this p2637 ≠
r2526.4)
In travel to fixed stop, the clamping torque or clamping force in the traversing block is
configured via the task parameter. This is specified in units of 0.01 Nm (rotary motor). The
function module is coupled to the torque limit of the basic system via the connector output
r2686[0] (torque limit upper) or r2686[1] (torque limit lower), which are connected to the
connector input p1528 (torque limit upper scaling) or p1529 (torque limit lower scaling). The
connector outputs r2686[0] (torque limit upper) and r2686[1] (torque limit lower) are set to
100% when fixed stop is not active. During active fixed stop, r2686[0] (torque limit upper) or
r2686[1] (torque limit lower) are evaluated as a percentage of p1522/p1523 in such a way
that the specified clamping torque or clamping force is limited.
When the fixed stop is acknowledged (p2637), the "Speed setpoint total" (p2562) is frozen,
as long as the binector input p2553 (fixed stop reached message) is set. The speed control
holds the setpoint torque due to the applied speed setpoint. The setpoint torque is output for
diagnosis via the connector output r2687 (torque setpoint).

Drive functions
7.3 Function modules

If the parameterized clamping torque is reached at the fixed stop, the status bit r2683.13
"Fixed stop clamping torque reached" is set.
Once the "Fixed stop reached" status has been detected, the traversing task "Travel to fixed
stop" is ended. The program advances to the next block depending on the task
parameterization. The drive remains in fixed stop until the next positioning task is processed
or the system is switched to jog mode. The clamping torque is therefore also applied during
subsequent waiting tasks. The continuation condition CONTINUE_EXTERNAL_WAIT can be
used to specify that the drive must remain at the fixed stop until a step enabling signal is
applied externally.
As long as the drive remains in fixed stop, the position setpoint is adjusted to the actual
position value (position setpoint = actual position value). Fixed stop monitoring and controller
enable are active.

Note
If the drive is in fixed stop, it can be referenced using the control signal "Set reference point."

If the axis leaves the position that it had at detection of the fixed stop by more than the
selected monitoring window for the fixed stop p2635, then the status bit r2683.12 is reset. At
the same time, the speed setpoint is set to zero, and fault F07484 "Fixed stop outside of the
monitoring window" is triggered with the reaction OFF3 (quick stop). The monitoring window
can be set using the parameter p2635 ("Fixed stop monitoring window"). It applies to both
positive and negative traversing directions and must be selected such that it will only be
triggered if the axis breaks away from the fixed stop.

Fixed stop is not reached

If the brake application point is reached without the "fixed stop reached" status being
detected, then the fault F07485 "Fixed stop is not reached" is output with fault reaction
OFF1, the torque limit is canceled and the drive cancels the traversing block.

Note
• The fault can be changed into an alarm (see section "Message configuration"), which
means that the drive program will advance to the next specified block.
• The target point must be sufficiently far inside the workpiece.

Interruption to "Travel to fixed stop"

The "travel to fixed stop" traversing task can be interrupted and continued using the
"intermediate stop" signal at the binector input p2640. The block is canceled using the
binector input signal p2641 "Reject traversing task" or by removing the controller enable. In
all of these cases, the drive is correspondingly braked. Measures are taken to prevent any
risk of damage if the block is canceled when an axis has almost reached the fixed stop
(setpoint already beyond the fixed stop, but still within the threshold for fixed stop detection).
For this purpose, the position setpoint is made to follow the actual position value after
standstill. As soon as the fixed stop is reached, the drive remains in fixed stop even after
cancelation. It can be moved away from the fixed stop using jog or by selecting a new
traversing task.

Note
The fixed stop monitoring window (p2635) is only activated when the drive is at the fixed stop
and remains active until the fixed stop is exited.

Vertical axis

Note
In servo mode, a torque limit offset (p1532) can be entered for vertical axes (see also the
chapter titled Servo control → Vertical axis).

With asymmetrical torque limits p1522 and p1523, the net weight is taken into account for
travel to fixed stop in parameters r2686 and r2687.
If, for example, with a suspended load, p1522 is set to +1000 Nm and p1523 to -200 Nm,
then a net weight of 400 Nm (p1522 - p1523) is assumed. If the clamping torque is now
configured as 400 Nm, then r2686[0] is preset to 80%, r2686[1] to 0% and r2687 to 800 Nm
when travel to fixed stop is activated.

Description
The direct setpoint input function allows for positioning (absolute, relative) and setup
(endless position-controlled) by means of direct setpoint input (e.g. via the PLC using
process data).
During traversing, the motion parameters can also be influenced (on-the-fly setpoint
acceptance) and an on-the-fly change can be undertaken between the Setup and Positioning
modes. The "direct setpoint input" mode (MDI) can also be used if the axis is not referenced
in the "setup" or "relative positioning" modes, which means that "flying referencing" (see the
separate section), flying synchronization, and post-referencing are possible.
The direct setpoint input function is activated by p2647 = 1. A distinction is made between
two modes: positioning mode (p2653 = 0) and setup mode (p2653 = 1).
In "positioning" mode, the parameters (position, velocity, acceleration and deceleration) can
be used to carry out absolute (p2648 = 1) or relative (p2648 = 0) positioning with the
parameter p2690 (fixed setpoint position).
In the setting-up mode, using parameters (velocity, acceleration and deceleration) "endless"
closed-loop position control behavior can be carried out.
It is possible to make a flying changeover between the two modes.
If continuous acceptance (p2649 = 1) is activated, changes to the MDI parameters are
accepted immediately. Otherwise the values are only accepted when there is a positive edge
at binector input p2650 (setpoint acceptance edge).

Note
Continuous acceptance p2649 = 1 can only be set with free telegram configuration
p0922 = 999. No relative positioning is allowed with continuous acceptance.

The direction of positioning can be specified using p2651 (positive direction specification)
and p2652 (negative direction specification). If both inputs have the same status, the
shortest distance is traveled during absolute positioning (p2648 = "1") of modulo axes
(p2577 = "1").

To use the positioning function, the drive must be in operating mode (r0002 = 0).
The following options are available for starting positioning:
● p2649 is "1" and positive edge on p2647
● p2649 is "0" and p2647 is "1"
– positive edge on p2650 or

MDI mode with the use of PROFIdrive telegram 110

If the connector input p2654 is preset with a connector input <> 0 (e.g. with PROFIdrive
telegram 110 with r2059[11]), then it will internally manage the control signals "Select
positioning type", "Positive direction selection" and "Negative direction selection". The
following characteristics are evaluated from the value of the connector input:
● xx0x = absolute → p2648
● xx1x = relative → p2648
● xx2x = ABS_POS → p2648, p2651
● xx3x = ABS_NEG → p2648, p2652

Intermediate stop and reject traversing task

The intermediate stop is activated by a 0 signal at p2640. After activation, the system brakes
with the parameterized deceleration value (p2620 or p2645).
The current traversing task can be rejected by a 0 signal at p2641. After activation, the
system brakes with the maximum deceleration (p2573).
The "intermediate stop" and "reject traversing task" functions are only effective in "traversing
blocks" and "direct setpoint input/MDI" modes.

Features
● Jog signals (p2589, p2590)

Description
Using parameter p2591 it is possible to change over between jog incremental and jog
velocity.
The traversing distances p2587 and p2588 and velocities p2585 and p2586 are entered
using the jog signals p2589 and p2590. The traversing distances are only effective for a "1"
signal at p2591 (jog, incremental). For p2591 = "0" then the axis moves to the start of the
traversing range or the end of the traversing range with the specified velocity.

7.3.6.9 Status signals

The status signals relevant to positioning mode are described below.

Tracking mode active (r2683.0)

The "Follow-up active mode" status signal shows that follow-up mode has been activated
which can be done by binector input p2655 (follow-up mode) or by a fault. In this status, the
position setpoint follows the actual position value, i.e. position setpoint = actual position
value.

Setpoint static (r2683.2)

The status signal "setpoint static" indicates that the setpoint velocity has a value of 0. The
actual velocity can deviate from zero due to a following error. While the status word has a
value of 0, a traversing task is being processed.

Traversing command active (r2684.15)

The status signal "traversing command active" indicates that a traversing command is active.
A motion command should be understood to comprise all motions (including jog, setup etc.).
Contrary to the status signal "setpoint static", the status signal remains active - e.g. if a
traversing command was stopped by a velocity override or intermediate stop.

SW limit switch + reached (r2683.7)

SW limit switch - reached (r2683.6)
These status signals indicate that the parameterized negative p2578/p2580 or positive
p2579/p2581 traversing range limit was reached or passed. If both status signals are 0, the
drive is located within the traversing limits.

Function Manual
Function Manual, 11/2009, 6SL3097-4AB10-0BP1 267
Drive functions
7.3 Function modules

Stop cam minus active (r2684.13)

Stop cam plus active (r2684.14)
These status signals indicate that the STOP cam minus p2569 or STOP cam plus p2570 has
been reached or passed. The signals are reset if the cams are left in a directly opposing the
approach direction.

Axis moves forwards (r2683.4)

Axis moves backwards (r2683.5)
Axis accelerates (r2684.4)
Drive decelerates (r2684.5)
Drive stationary (zero speed) (r2199.0)
These signals display the current motion status. If the actual absolute speed is less or equal
to p2161, then the status signal "drive stationary" is set - otherwise it is deleted. The signals
are appropriately set if jog mode, reference point approach or a traversing task is active.

Cam switching signal 1 (r2683.8)

Cam switching signal 2 (r2683.9)
The electronic cam function can be implemented using these signals. Cam switching signal 1
is 0 if the actual position is greater than p2547 - otherwise 1. Cam switching signal 2 is 0 if
the actual position is greater than p2548 - otherwise 1. This means that the signal is deleted
if the drive is located behind (after) the cam switching position. The position controller
initiates these signals.

Direct output 1 (r2683.10)

Direct output 2 (r2683.11)
If a digital output is parameterized, the function "direct output 1" or "direct output 2", then it
can be set by a corresponding command in the traversing task (SET_O) or reset
(RESET_O).

Following error in tolerance (r2684.8)

When the axis is traversed, closed-loop position controlled, using a model, the permissible
following error is determined from the instantaneous velocity and the selected Kv factor.
Parameter p2546 defines a dynamic following error window that defines the permissible
deviation from the calculated value. The status signal indicates as to whether the following
error is within the window (status 1).

Function Manual
268 Function Manual, 11/2009, 6SL3097-4AB10-0BP1
 Drive functions
7.3 Function modules

Target position reached (r2684.10)

The status signal "target position reached" indicates that the drive has reached its target
position at the end of a traversing command. This signal is set as soon as the actual drive
position is within the positioning window p2544 and is reset, if it leaves this window.
The status signal is not set, if
● Signal level 1 at binector input p2554 "signal traversing command active".
● Signal level 0 at binector input p2551 "signal setpoint static".
The status signal remains set, until
● Signal level 1 at binector input p2551 "signal setpoint static".

Reference point set (r2684.11)

The signal is set as soon as referencing has been successfully completed. It is deleted as
soon as no reference is there or at the start of the reference point approach.

Acknowledgement, traversing block activated (r2684.12)

A positive edge is used to acknowledge that in the mode "traversing blocks" a new traversing
task or setpoint was transferred (the same signal level as binector input p2631 activate
traversing task). In the mode "direct setpoint input / MDI for setting-up/positioning" a positive
edge is used to acknowledge that a new traversing task or setpoint was transferred (the
same signal level as binector input p2650 "edge setpoint transfer", if the transfer type was
selected using a signal edge (binector input p2649 "0" signal)).

Velocity limiting active (r2683.1)

If the actual setpoint velocity exceeds the maximum velocity p2571 - taking into account the
velocity override - it is limited and the control signal is set.

7.3.7 Extended setpoint channel

Description
In the servo operating mode, the extended setpoint channel is deactivated by default. If an
extended setpoint channel is required, it has to be activated. The extended setpoint channel
is always activated in the vector operating mode.

Properties of servo mode without the "extended setpoint channel" function module
● The setpoint is directly interconnected to p1155[D] (e.g. from a higher-level control or
technology controller)
● Dynamic Servo Control (DSC) only
When using DSC, the "extended setpoint channel" is not used. This unnecessarily uses
the computation time of the Control Unit and, for servo, can be deactivated.
● Deceleration ramp OFF1 via p1121[D]
● Deceleration ramp OFF3 via p1135[D]
● For PROFIdrive telegrams 2 to 103 and 999 only (free assignment)
● STW 1 bit 5 (freeze ramp-function generator), no function

7.3.7.1 Activation of the "extended setpoint channel" function module

The "extended setpoint channel" function module can be activated via the commissioning
Wizard or the drive configuration (configure DDS).
You can check the current configuration in parameter r0108.8. Once you have set the
configuration, you must download it to the Control Unit where it is stored in a non-volatile
memory.

Setpoint sources
The closed-loop control setpoint can be interconnected from various sources using BICO
technology (e.g. to p1070 CI: main setpoint (see function diagram 3030)).
There are various options for setpoint input:
● Fixed speed setpoints
● Motorized potentiometer
● Jog
● Field bus

● About the analog input AI of the CU 305

7.3.7.3 Jog

Description
This function can be selected via digital inputs or via a field bus (e.g. PROFIBUS).
The setpoint is, therefore, predefined via p1058[D] and p1059[D].
When a jog signal is present, the motor is accelerated to the jog setpoint with the
acceleration ramp of the ramp-function generator (referred to the maximum speed p1082;
see diagram "Function chart: jog 1 and jog 2"). After the jog signal has been deselected, the
motor is decelerated via the set ramp of the ramp-function generator.

The "Jog" function is not PROFIdrive-compliant!

● Jog setpoints are approached and exited via the ramp-function generator.
● The jog function can be activated from the "ready for switching on" status and from the

● If ON/OFF1 = "1" and jog are selected simultaneously, ON/OFF1 has priority.
● OFF2 and OFF3 have priority over jog.
● In jog mode, the main speed setpoints (r1078) and the supplementary setpoints 1 and 2

● In jog mode, ZSWA.02 (operation enabled) is set to "0" because the speed setpoint has
not been enabled for control.
● The ramp-function generator cannot be frozen (via p1141) in jog mode (r0046.31 = 1).

7.3.7.4 Fixed speed setpoints

Description
This function can be used to specify preset speed setpoints. The fixed setpoints are defined
in parameters and selected via binector inputs. Both the individual fixed setpoints and the
effective fixed setpoint are available for further interconnection via a connector output (e.g. to
connector input p1070 - CI: main setpoint).

Properties
● Number of fixed setpoints: Fixed setpoint 1 to 15
● Selection of fixed setpoints: Binector input bits 0 to 3
– Binector input bits 0, 1, 2, and 3 = 0 → setpoint = 0 active
– Unused binector inputs have the same effect as a "0" signal

7.3.7.5 Motorized potentiometer

Description
This function is used to simulate an electromechanical potentiometer for setpoint input.
You can switch between manual and automatic mode for setpoint input. The specified
setpoint is routed to an internal ramp-function generator. Setting values, start values and
braking with OFF1 do not require the ramp-function generator of the motorized
potentiometer.
The output of the ramp-function generator for the motorized potentiometer is available for
further interconnection via a connector output (e.g. interconnection to connector input p1070
- CI: main setpoint, an additional ramp-function generator is then active).

Properties for manual mode (p1041 = "0")

● Separate binector inputs for Raise and Lower are used to adjust the input setpoint:
– p1035 BI: Motorized potentiometer, setpoint, raise
– p1036 BI: Motorized potentiometer, setpoint, lower
● Invert setpoint (p1039)
● Configurable ramp-function generator, e.g.:
– Ramp-up/ramp-down time (p1047/p1048) referred to p1082
– Setting value (p1043/p1044)
– Initial rounding active/not active (p1030.2)
● Non-volatile storage via p1030.3
● Configurable setpoint for Power ON (p1030.0)
– Starting value is the value in p1040 (p1030.0 = 0)
– Starting value is the stored value (p1030.0 = 1)

7.3.7.6 Main/supplementary setpoint and setpoint modification

Description
The supplementary setpoint can be used to incorporate correction values from lower-level
controllers. This can be easily carried out using the addition point for the main/supplementary
setpoint in the setpoint channel. Both variables are imported simultaneously via two separate
or one setpoint source and added in the setpoint channel.

Description
A reverse operation involves a direction reversal. Selecting setpoint inversion p1113[C] can
reverse the direction in the setpoint channel.
Parameter p1110[C] or p1111[C] can be set respectively to prevent input of a negative or
positive setpoint via the setpoint channel. However, the following settings for minimum speed
(p1080) in the setpoint channel are still operative. With the minimum speed, the motor can
turn in a negative direction, although p1110 = 1 is set.

7.3.7.8 Suppression bandwidths and setpoint limits

Description
In the range 0 U/min to setpoint speed, a drive train (e.g. motor, coupling, shaft, machine)
can have one or more points of resonance, which can result in vibrations. The suppression
bandwidths can be used to prevent operation in the resonance frequency range.
The limit speeds can be set via p1080[D] and p1082[D]. These limits can also be changed
during operation with the connectors p1085[C] and p1088[C].

7.3.7.9 Ramp-function generator

Description
The ramp-function generator is used to limit acceleration in the event of abrupt setpoint
changes, which helps prevent load surges throughout the drive train. The ramp-up time
p1120[D] and ramp-down time p1121[D] can be used to set mutually independent
acceleration and deceleration ramps. This allows a controlled transition to be made in the
event of setpoint changes.
The maximum speed p1082[D] is used as a reference value for calculating the ramps from
the ramp-up and ramp-down times. A special adjustable ramp can be set via p1135 for quick
stop (OFF3), e.g. for rapid controlled deceleration when an emergency OFF button is
pressed.
There are two types of ramp-function generator:
● Basic ramp-function generator with
– Acceleration and deceleration ramps
– Ramp for quick stop (OFF3)
– Tracking can be selected via a binector input
– Setting values for the ramp-function generator
● Extended ramp-function generator also has
– Initial and final rounding off

Note
The ramp-function generator cannot be frozen (via p1141) in jog mode (r0046.31 = 1).

● Select ramp-function generator rounding type p1134[D]

– p1134 = "0": continuous smoothing rounding is always active. Overshoots may occur.
If the setpoint changes, final rounding is carried out and then the direction of the new
setpoint is adopted.
– p1134 = "1": non-continuous smoothing changes immediately to the direction of the
new setpoint when the setpoint is changed.
● Configure ramp-function generator, deactivate rounding at zero crossing p1151[D]
● Freezing of the ramp-function generator using p1141 (not in jog mode r0046.31 = 0)

Ramp-function generator tracking

If the drive is in the area of the torque limits, the actual speed value is removed from the
speed setpoint. The ramp-function generator tracking updates the speed setpoint in line with
the actual speed value and so levels the ramp. p1145 can be used to deactivate ramp-
function generator tracking (p1145 = 0) or set the permissible following error (p1145 > 1). If
the permissible following error is reached, then the speed setpoint at the ramp-function
generator output will only be further increased in the same proportion as the actual speed
value.
Ramp-function generator tracking can be activated for the basic and the extended ramp-
function generators.

7.3.8 Free function blocks

7.3.8.1 Overview

Application, properties
A logic operation, which connects several states (e.g. access control, plant status) to a
control signal (e.g. ON command), is required for controlling the drive system in a wide
variety of applications.
Along with logic operations, a number of mathematical functions and storing elements are
becoming increasingly important in drive systems.
This functionality is only available as a "free function blocks" function module (FBLOCKS) on
the SERVO drive object type of SINAMICS S110.
In the free function blocks, analog signals are treated as dimensionless per unit variables
(see the "Connection to the drive" chapter).

Note
This additional functionality increases the calculation time load. This means that the
maximum possible configuration with a Control Unit may be restricted (see the "Calculation
time load" chapter).

Configuration and operation

The free function blocks are configured at the parameter level. The following parameters are
required for this:
● Input parameters (e.g. inputs I0 ... I3 for the AND function block).
● Output parameters (e.g. output Y for numeric change-over switch NSW).
● Adjustable parameters (e.g. pulse duration for pulse generator MFP).
● Runtime group (this includes the sampling time; the free function blocks are not
computed in the factory setting).
● Run sequence within the runtime group.
A parameter is assigned to each input, output, and adjustable variable. These can be
accessed with the STARTER commissioning software or via the BOP. The "free function
blocks" can all be interconnected at BICO level.
The "free function blocks" do not support data set dependency.

7.3 Function modules

Runtime group, sampling time, and run sequence

Runtime groups
Runtime groups are groups of free function blocks within the system that are computed in
the same sampling time and at a specific time.
A total of 10+1 "runtime groups" (runtime group 0 to 9 and runtime group 9999 (= runtime
group is not computed)) are available for which the sampling time can be set in specific
intervals.
Each function block is assigned one runtime group via a parameter. In the factory setting, the
value 9999 (i.e. the function block is not computed) is assigned to each function block.
Example:
For function block ADD 0 (see the SINAMICS S110 List Manual, function diagram 7220), the
runtime group is set in p20096.
The runtime groups are divided into one "fixed runtime group" and several "free runtime
groups".
● The "fixed runtime group" is called at a defined point in the system runtime. The sole fixed
runtime group (p20000[x] = 9003) is arranged before the setpoint channel and calculated
in the sampling time of the setpoint channel (4 ms). This set value is only available for the
SERVO drive object type.
● The "free runtime groups" are only defined via their sampling time.

Note
If the same sampling time is assigned to two or more runtime groups (the same fixed or
free runtime group), the runtime groups are processed in numerical order.

Example
p20000[0] = p20000[3] = p20000[9] = 9003
The computing sequence is:
runtime group 0 first, then runtime group 3, then runtime group 9, and then the setpoint
channel.
The minimum sampling time is 1 ms.
The actual sampling time in ms is displayed for each runtime group in parameter
r20001[0...9].

Function Manual
290 Function Manual, 11/2009, 6SL3097-4AB10-0BP1
 Drive functions
7.3 Function modules

In the factory setting, none of the runtime groups is called (p20000[x] = 0).

Note
The assignment of a runtime group can only be changed if closed loop control is disabled.
When changing, the runtime group involved is first logged off from the sampling time
management and then logged on again with the new assignment. The runtime group is not
calculated during this operation.
Logon and logoff are performed in a background process of the drive unit. This is the reason
that duration is not defined and depends on the actual calculation time load. This influences
the output signal characteristic in the case of time-dependent blocks (e.g. DIF derivative
action element). Prior to the first computation cycle after logging back on, internal status
variables of the blocks are partially reset.
For both of these reasons, this can result in jumps in the output signal of blocks, which for
example can influence the torque/force setpoint and, for axes in operation, the torque/force
actual value as well. Logic signals can also assume an unexpected state at this instant.

Sampling times
Two types of sampling times are available for runtime groups:
● Sampling times generated in the hardware:
Every integer multiple of the basic sampling time (r20002) can be generated as a
sampling time in p20000[0...9] in the range from 1 x r20002 to 256 x r20002, subject to
the following limits:
– Min. sampling time = 1 ms
– Max. sampling time = r20003
Sampling times of 1 ms ... r20003 - r20002 are generated in the hardware from these.

Note
As regards offline configuration using STARTER commissioning software, values
0 ... 256 can be entered in p20000[x], even if this violates the limits stated above for the
hardware sampling times from 1 ms ... r20003 - r20002 and r20003.
This will only be detected after the Control Unit has been downloaded and generates fault
F01042 (parameter error during project download).

The basic sampling time for the SERVO drive object type in SINAMICS S110 is as
follows:
r20002 = 0.25 ms (current controller sampling time)
● Sampling times generated in the software:
These sampling times are generated as integer multiples of the basic value for software
sampling times and must be read in parameter r20003 when the "free function blocks"
function module is active.
For the possible set values for the software sampling times, refer to the parameter
description for p20000 (see SINAMICS S110 List Manual).

Note
When p20000[k] = 0, the corresponding runtime group (and, in turn, all the associated
function blocks) is not computed.

The sampling time of runtime group k is displayed in r20001[k] in ms.

Example for the adjustable sampling times in SINAMICS S110:

The basic sampling time (r20002) on the SERVO drive object is 250 µs, which means that
the following sampling times are possible:
● Hardware sampling times:
p20000[x] = 0 (runtime group not computed)
p20000[x] = 1 x 250 µs = 250 µs (not permitted because less than 1 ms)
p20000[x] = 2 x 250 µs = 500 µs (not permitted because less than 1 ms)
p20000[x] = 3 x 250 µs = 750 µs (not permitted because less than 1 ms)
p20000[x] = 4 x 250 µs = 1000 µs
p20000[x] = 5 x 250 µs = 1250 µs
...
p20000[x] = 31 x 250 µs = 7750 µs (longest hardware sampling time)
p20000[x] = 32 x 250 µs = 8000 µs (can be selected as a multiple of r20002 - but is a
software sampling time)
p20000[x] = 33 x 250 µs = 8250 µs (rejected because greater than r20003!)
The settings below are no longer possible because the sampling times would exceed 8 ms.
The basic value of the software sampling time is: r20003 = 8 ms.
● Software sampling times:
p20000[x] = 1001: Sampling time = 1 x 8 ms = 8 ms
p20000[x] = 1002: Sampling time = 2 x 8 ms = 16 ms
p20000[x] = 1003: Sampling time = 3 x 8 ms = 24 ms
p20000[x] = 1004: Sampling time = 4 x 8 ms = 32 ms
p20000[x] = 1005: Sampling time = 5 x 8 ms = 40 ms
p20000[x] = 1006: Sampling time = 6 x 8 ms = 48 ms
p20000[x] = 1008: Sampling time = 8 x 8 ms = 64 ms
p20000[x] = 1010: Sampling time = 10 x 8 ms = 80 ms
p20000[x] = 1012: Sampling time = 12 x 8 ms = 96 ms
p20000[x] = 1016: Sampling time = 16 x 8 ms = 128 ms
p20000[x] = 1020: Sampling time = 20 x 8 ms = 160 ms
p20000[x] = 1024: Sampling time = 24 x 8 ms = 192 ms
p20000[x] = 1032: Sampling time = 32 x 8 ms = 256 ms
p20000[x] = 1040: Sampling time = 40 x 8 ms = 320 ms
p20000[x] = 1048: Sampling time = 48 x 8 ms = 384 ms
p20000[x] = 1064: Sampling time = 64 x 8 ms = 512 ms
p20000[x] = 1096: Sampling time = 96 x 8 ms = 768 ms

Run sequence
In the factory setting, each free function block is assigned a default setting for the run
sequence. The run sequence of consecutive free function blocks within a runtime group can
be optimized by changing these values accordingly.
A run sequence value can be used on a drive object once only. If the same run sequence
value is assigned twice in online mode for a drive object, the second value is rejected and
the first value retained.
The run sequence can be set to between 0 and 32000. A function block with a lower run
sequence value is computed within a runtime group before one with a higher value.

Note
If configuration is carried out OFFLINE, you can set each run sequence value at the outset
(e.g. a value can also be assigned to more than one function block simultaneously). The
system does not check this until the configuration has been downloaded to the Control Unit.

Once downloaded, the parameter values are checked in the order of the parameter
numbers. If the system detects that the run sequence value for one function block is already
being used by a different function block, the value is not applied and fault F01042 (message
in STARTER: Error occurred when downloading) is output. You are informed of this in the
"Target system output" window.

Note
In the factory setting, value range 10 ... 750 is already assigned the run sequence values of
the function blocks.
In user configurations, for example, the only run sequence values outside this range which
should be used are those above 1000. This will avoid conflicts during the download process
with the run sequence values that have already been assigned.

If at all possible, the process signals for a drive object should only be processed by the
function blocks on this drive object.

Connection to the drive

Connector inputs (CI) and connector outputs (CO) on the free function blocks (p20094 ...
p20286) have the properties of per unit variables. This means that calculations in the free
function blocks are only carried out with per unit signal values (1.0 = 100%). Conversion to
the connectors of the drive with units is performed automatically.

Note
The following manual contains function diagrams for "free function blocks" and all the
product-dependent function diagrams available for SINAMICS S110 (e.g. function diagram

It is also to be called with the sampling time 2 x r20003. The runtime group number is
chosen here at random.

7.3.8.2 Commissioning

Activating the "free function blocks" function module

STARTER commissioning software

Activation with the STARTER commissioning software is only possible offline and is
performed via the "Properties" dialog box for the drive objects. The "free function blocks" can
be selected on the "Function modules" tab.
Open the relevant project with STARTER and left-click the plus sign in the project navigator
once to open the sub-elements.
Right-click once to display the shortcut menu for the selected drive object. In each case, left-
click once to select "Properties" and "Function modules". Scroll to "Free function blocks".
Select this function module (set the checkbox) and confirm with "OK". The properties dialog
is then closed automatically.
In its factory setting, the "Free function blocks" checkbox is not selected. If you select the
checkbox and confirm with "OK", the "free function blocks" function module is activated once
the project has been downloaded.

Activating the individual function blocks

Each individual function block is assigned to a runtime group via two parameters:
● The first parameter defines the runtime group.
● The second parameter defines the run sequence within the runtime group.
Within a runtime group, a function block with a lower value for the run sequence is computed
before a function block with a higher value.

Note
In the factory setting, each function block is assigned to runtime group 9999. This means
that the function block is not computed.

You also have to ensure that runtime group x is called cyclically. This can be done by setting
parameter p20000[x] to a value > 0.
Example:
On the "SERVO" drive object type, the basic software sampling time r20003 is 8 ms.
Runtime group 0 is to be called every 16 ms.
This means:
Set p20000[0] = 1002 (sampling time 2 x r20003).
Check via r20001[0] = 16.0 ms (sampling time of runtime group 0).

Calculation time load for firmware version 4.1

Processing of free function blocks requires calculation time. If calculation time is becoming
short, you will need to check whether all the activated function modules are required and
whether all the function blocks used need to be calculated within the same sampling time.
The calculation time load can be reduced by either deactivating function modules or
assigning used function blocks to a runtime group with a longer sampling time.

Dependency
The resulting calculation time load depends on the following:
● Number of activated runtime groups (p20000[x] > 0)
● Number of calculated function blocks
● Sampling time

Calculation time online

The calculation time load shown in r9976[0...7] does not include the additional load caused
by the free function blocks.

Note
For the basic SINAMICS system as of firmware version 4.1, the following applies:
As of this version, the process of determining the calculation time load is different. For this
reason, r9976[0...7] no longer contains the calculation time load generated by the "free
function blocks".

Calculation time offline

When the system is in offline mode, SIZER offers an approximate statement regarding
whether a configuration can be computed on SINAMICS S110. The additional calculation
time load is not taken into account when the "free function blocks" function module is
activated.

7.3 Function modules

Calculation time load for firmware version 4.3 and higher

For firmware version 4.3 and higher, after a download or a parameter change (e.g. where the
sampling time of a runtime group is changed) using the configuration data, the Control Unit
(CU) determines the calculation time load to be expected (including the load associated with
FBLOCKS). This value is displayed in r9976 (system utilization) for the system as a whole.
If the calculated average calculation time load for the system as a whole r9976[1] or the
maximum utilization (including the interruption as a result of time slices with a shorter
sampling time) in a sampling time r9976[5] exceeds 100.00%, this generates fault F01054
(CU: System limit exceeded) to be output with fault reaction OFF2.
The utilization is calculated on the Control Unit, i.e. the utilization values are displayed in
STARTER/SCOUT in online mode only.
The resulting calculation time load caused by FBLOCKS depends on the following:
● Number of calculated runtime groups
● Sampling time of the runtime groups
● Number of calculated blocks
● Calculated block types
The proportion of the calculation time load associated with FBLOCKS is displayed in
r20005[0…9] for runtime groups 0 to 9 (as of firmware version 4.3). Note that the calculation
time load for a runtime group k can only be calculated if this has been logged on for cyclic
processing (p20000[k-1] ≠ 0).
For firmware version 4.3 and higher, and unlike with version 4.1, if a parameter is changed
(in the STARTER online mode) that has an influence on the calculation time load (e.g.
changes the sampling time of a runtime group in FBLOCKS), the drive unit immediately
recalculates r9976 (and r20005). For parameters which can only be changed in the device
states C1 (commissioning device) or C2 (commissioning drive object), i.e. only when
STARTER/SCOUT is in the offline mode, r9976 is only updated after the project has been
downloaded and the Control Unit has powered up.
For firmware version 4.3, the calculation time load displayed in r9976 can be up to 100.00%
without triggering a fault.

Number of possible hardware sampling times

The sampling times for the runtime groups can be selected in p20000[x] as a multiple of
r20002 (basic sampling time of hardware time slices), a multiple of r20003 (basic sampling
time of software time slices), or on the basis of the sampling time of a basic SINAMICS
system function (e.g. when p20000[x] = 9003 == "before setpoint channel" from the sampling
time of the setpoint channel).
Only sampling times to which the following applies can be set as hardware sampling times:
1 ms ≤ T_sampling ≤ r20003 - r20002 in p20000[x]
Sampling time r20003 is always a software sampling time regardless of whether it is set as
p20000[x] = 1001 (== 1 x r20003) or as a multiple of r20002 (p20000[x] ≤ 256).

Hardware sampling times, number, and assignment

During configuration, note that the number of hardware sampling times (1 ms ≤ time period
T_sampling < r20003 - r20002) used by the basic SINAMICS system and "free function
blocks" is restricted as follows:
● SINAMICS S110 → no. of hardware sampling times = 11
The assignment of the available hardware sampling times is displayed in r20008[0...12] as
follows (STARTER/SCOUT: in online mode only):
● Value = 0.0 → sampling time not assigned
● Value ≠ 0.0 (not equal to 0.0) → sampling time in ms
● Value = 9999900.00000 → sampling time not supported

Note
Note that a long-term trace registers a sampling time of 2 ms and the trace registers
sampling times in accordance with the selected trace clock cycle. If these sampling times
have not already been registered by the basic SINAMICS system or "free function blocks"
(FBLOCKS), these functions require additional free hardware sampling times.
The registered hardware sampling times can be read (if the FBLOCKS are activated) in
r20008[0...12]. The current number of free hardware sampling times can be read in
r7903.

Hardware sampling times, usage

A sampling time can be used simultaneously by more than one runtime group of "free
function blocks" and the basic SINAMICS system.
For this reason, the runtime groups should ideally be registered to existing sampling times or
- if it makes more sense due to the function - the fixed runtime group "Calculate before
setpoint channel" should be used.
For internal purposes, the drive unit always requires at least two free hardware sampling
times, This is why the current number of free hardware sampling times can be read in r7903.

Project download, fault message, and procedure

If too many different hardware sampling times are configured offline, a fault message is not
output until the project is downloaded.
In this case, proceed as follows:
1. When the project is in offline mode, switch the free runtime groups assigned hardware
sampling times to software sampling times.
– Hardware sampling times (p20000 < 256)
– Software sampling times (p20000 ≥ 1001)
The assignment of fixed runtime groups (p20000 = 9003) does not need to be
changed because the fixed runtime group uses the same sampling time as the
assigned basic SINAMICS system function.
2. Download the project again.
3. Once the project has been downloaded and the Control Unit has booted, check:
– r7903: Number of hardware sampling times still available
– r20008: Number of hardware sampling times already registered by the basic
SINAMICS system
4. Adapt the parameterization of the runtime groups accordingly.

Note
The number of different hardware sampling times possible on a Control Unit is restricted.
For this reason, preference should be given to software sampling times (multiple of
r20003) or, where applicable, the fixed runtime group "Calculate before setpoint channel"
(p20000[0...9] = 9003).

Brief description
REAL-type divider with two inputs

Mode of operation
This function block divides the value entered at input X0 by the value entered at input X1.
The result is output at the outputs as follows:
● Y output: Quotient with places before and after the decimal point
● YIN output: Integer quotient
● MOD output: Division remainder (absolute remainder value, MOD = (Y - YIN) × X0)
The Y output is limited to a range of approx. -3.4E38 to +3.4E38.

If output value Y exceeds the permissible value range of approx. -3.4E38 to 3.4E38
(because divisor X1 is very small or zero), the limit value of the output range with the correct
sign is output at the Y output. At the same time, digital output QF is set to 1.
With a division of 0/0, block output Y remains unchanged. Digital output QF is set to 1.

7.3.8.22 PT1 (smoothing element)

Brief description
● First-order delay element with setting function
● Used as smoothing element

Mode of operation
Setting function not active (S = 0)
Input variable X, dynamically delayed by smoothing time constant T, is switched to output Y.
T determines the steepness of the rise of the output variable. It specifies the time at which
the transfer function has risen to 63% of its full-scale value.
When t = 3T, the transfer function reaches approximately 95% of its full-scale value.
The internally fixed proportional gain is 1 and cannot be changed.
If T/TA is sufficiently large (T/TA > 10), the transfer function has the following characteristic:
Y (t) = X · (1 - e-t/T)
Constraint: t = n · TA
The discrete values are calculated according to the following algorithm:
Yn = Yn-1 + (TA/T) (Xn - Yn-1)

Yn Value of Y in sampling time n

Yn-1 Value of Y in sampling time n-1
Xn Value of X in sampling time n
Setting function active (S = 1)
When the setting function is active, the current setting value SVn is accepted at the output
variable:
Yn = SVn

Note
The larger T/TA is, the smaller the amplitude change at Y from one sampling time to the
next. TA is the configured sampling time of the function block.

Brief description
● Function block with integrating action
● Integrator functions:
– Set initial value
– Adjustable integral time constant
– Adjustable limits
– For normal integrator operation, a positive limit value must be specified for LU and a
negative limit value for LL.

Mode of operation
The change in output variable Y is proportional to input variable X and inversely proportional
to the integral time constant TI.
Output Y of the integrator can be limited via the inputs LU and LL. If the output reaches one
of the two limits, a signal is sent via the outputs QU or QL. If LL ≥ LU, then output Y = LU.
The discrete values (TA is the configured sampling time of the function block) are calculated
according to the following algorithm:
Yn = Yn-1 + (TA/TI) Xn

Yn Value of Y in sampling time n

Yn-1 Value of Y in sampling time n-1
Xn Value of X in sampling time n
When S = 1, the output variable Y is set to the setting value SV. Two functions can be
performed via S:
● Track integrator (Y = SV)
The digital input is S = 1 and the setting value SV is changed. If applicable, the output
makes a jump to the setting value immediately after the setting operation.
● Set integrator to initial value SV.
S is switched to 1. S is then set to 0, and the integrator starts from SV in the direction
specified by the polarity of input variable X.

8.1 Standards and regulations

8.1.1 General information

8.1.1.1 Aims
Manufacturers and operating companies of equipment, machines, and products are
responsible for ensuring the required level of safety. This means that plants, machines, and
other equipment must be designed to be as safe as possible in accordance with the current
state of the art. To ensure this, companies describe in the various standards the current
state of the art covering all aspects relevant to safety. When the relevant Standards are
observed, this ensures that state-of-the-art technology has been utilized and, in turn, the
erector/builder of a plant or a manufacturer of a machine or a piece of equipment has fulfilled
his appropriate responsibility.
Safety systems are designed to minimize potential hazards for both people and the
environment by means of suitable technical equipment, without restricting industrial
production and the use of machines more than is necessary. The protection of man and
environment must be assigned equal importance in all countries, which is it is important that
rules and regulations that have been internationally harmonized are applied. This is also
designed to avoid distortions in the competition due to different safety requirements in
different countries.
There are different concepts and requirements in the various regions and countries of the
world when it comes to ensuring the appropriate degree of safety. The legislation and the
requirements of how and when proof is to be given and whether there is an adequate level of
safety are just as different as the assignment of responsibilities.
The most important thing for manufacturers of machines and companies that set up plants
and systems is that the legislation and regulations in the country where the machine or plant
is being operated apply. For example, the control system for a machine that is to be used in
the US must fulfill local US requirements even if the machinery construction company (OEM)
is based in the European Economic Area (EEA).

8.1 Standards and regulations

8.1.1.2 Functional safety

Safety, from the perspective of the object to be protected, cannot be split-up. The causes of
hazards and, in turn, the technical measures to avoid them can vary significantly. This is why
a differentiation is made between different types of safety (e.g. by specifying the cause of
possible hazards). "Functional safety" is involved if safety depends on the correct function.
To ensure the functional safety of a machine or plant, the safety-related parts of the
protection and control devices must function correctly. In addition, the systems must behave
in such a way that either the plant remains in a safe state or it is brought into a safe state if a
fault occurs. In this case, it is necessary to use specially qualified technology that fulfills the
requirements described in the associated Standards. The requirements to achieve functional
safety are based on the following basic goals:
● Avoiding systematic faults
● Controlling systematic faults
● Controlling random faults or failures
Benchmarks for establishing whether or not a sufficient level of functional safety has been
achieved include the probability of hazardous failures, the fault tolerance, and the quality that
is to be ensured by minimizing systematic faults. This is expressed in the Standards using
different terms. In IEC/EN 61508, IEC/EN 62061, IEC/EN 61800-5-2: "Safety Integrity Level"
(SIL) and
EN ISO 13849-1:2006: "Categories" and "Performance Level" (PL).

8.1.2 Safety of machinery in Europe

The EU Directives that apply to the implementation of products are based on Article 95 of the
EU contract, which regulates the free exchange of goods. These are based on a new global
concept ("new approach", "global approach"):
● EU Directives only specify general safety goals and define basic safety requirements.
● Technical details can be defined by means of standards by Standards Associations that
have the appropriate mandate from the commission of the European Parliament and
Council (CEN, CENELEC). These standards are harmonized in line with a specific
directive and listed in the official journal of the commission of the European Parliament
and Council. Legislation does not specify that certain standards have to be observed.
When the harmonized Standards are observed, it can be assumed that the safety
requirements and specifications of the Directives involved have been fulfilled.
● EU Directives specify that the Member States must mutually recognize domestic
regulations.
The EU Directives are equal. This means that if several Directives apply for a specific piece
of equipment or device, the requirements of all of the relevant Directives apply (e.g. for a
machine with electrical equipment, the Machinery Directive and the Low-Voltage Directive
apply).

8.1 Standards and regulations

8.1.2.1 Machinery Directive

The basic safety and health requirements specified in Annex I of the Directive must be
fulfilled for the safety of machines.
The protective goals must be implemented responsibly to ensure compliance with the
Directive.
Manufacturers of a machine must verify that their machine complies with the basic
requirements. This verification is facilitated by means of harmonized standards.

8.1.2.2 Harmonized European Standards

The two Standards Organizations CEN (Comité Européen de Normalisation) and CENELEC
(Comité Européen de Normalisation Électrotechnique), mandated by the EU Commission,
drew-up harmonized European standards in order to precisely specify the requirements of
the EC directives for a specific product. These standards (EN standards) are published in the
official journal of the commission of the European Parliament and Council and must be
included without revision in domestic standards. They are designed to fulfill basic health and
safety requirements as well as the protective goals specified in Annex I of the Machinery
Directive.
When the harmonized standards are observed, it is "automatically assumed" that the
Directive is fulfilled. As such, manufacturers can assume that they have observed the safety
aspects of the Directive under the assumption that these are also covered in this standard.
However, not every European Standard is harmonized in this sense. Key here is the listing in
the official journal of the commission of the European Parliament and Council.
The European standards regarding the safety of machines are structured in a hierarchical
manner as follows:
● A standards (basic standards)
● B standards (group standards)
● C standards (product standards)

Type A standards/basic standards

A standards include basic terminology and definitions relating to all types of machine. This
includes EN ISO 12100 (previously EN 292) "Safety of Machines, Basic Terminology,
General Design Principles."
A standards are aimed primarily at the bodies responsible for setting the B and C standards.
The measures specified here for minimizing risk, however, may also be useful for
manufacturers if no applicable C standards have been defined.
Type B standards/group standards
B standards cover all safety-related standards for various different machine types. B
standards are aimed primarily at the bodies responsible for setting C standards. They can
also be useful for manufacturers during the machine design and construction phases,
however, if no applicable C standards have been defined.

Safety Integrated Functions
8.1 Standards and regulations

A further sub-division has been made for B standards:

● Type B1 standards for higher-level safety aspects (e.g. ergonomic principles, safety
clearances from sources of danger, minimum clearances to prevent parts of the body
from being crushed).
● Type B2 standards for protective safety devices are defined for different machine types
(e.g. EMERGENCY STOP devices, two-hand operating circuits, interlocking elements,
contactless protective devices, safety-related parts of controls).

Type C standards/product standards

C standards are product-specific standards (e.g. for machine tools, woodworking machines,
elevators, packaging machines, printing machines, etc.). Product standards list requirements
for specific machines. The requirements can, under certain circumstances, deviate from the
basic and group standards. Type C/product standards have the highest priority for machine
manufacturers who can assume that it fulfills the basic requirements of Annex I of the
Machinery Directive (automatic presumption of compliance). If no product standard has been
defined for a particular machine, type B standards can be applied when the machine is
constructed.
A complete list of the standards specified and the mandated draft standards are available on
the Internet at the following address:
http://www.newapproach.org/
Recommendation: Due to the rapid pace of technical development and the associated
changes in machine concepts, the standards (and C standards in particular) should be
checked to ensure that they are up to date. Please note that the application of a particular
standard may not be mandatory provided that all the safety requirements of the applicable
EU directives are fulfilled.

8.1.2.3 Standards for implementing safety-related controllers

If the functional safety of a machine depends on various control functions, the controller must
be implemented in such a way that the probability of the safety functions failing is sufficiently
minimized. The standards EN ISO 13849-1:2006 (previously EN 954-1) and EN 62061
define principles for implementing safety-related machine controllers which, when properly
applied, ensure that all the safety requirements of the EC Machinery Directive are fulfilled.
These standards ensure that the relevant safety requirements of the Machinery Directive are
fulfilled.

8.1.2.4 EN ISO 13849-1:2006 (previously EN 954-1)

A qualitative analysis (to EN 954-1) is not sufficient for modern controllers due to their
technology. Among other things, EN 954-1 does not take into account time behavior (e.g.
test interval and/or cyclic test, lifetime). This led to the probability-based approach of EN ISO
13849-1:2006 (probability of failure per time unit).
EN ISO 13849-1:2006 is based on the familiar categories used in EN 954-1. It now also
takes into account complete safety functions and all the devices required to execute these.
In addition to the qualitative approach of EN 954-1, EN ISO 13849-1:2006 now includes a
quantitative analysis of the safety functions. Performance levels (PL), which are based on
the categories, are used. The following safety-related characteristic quantities are required
for devices/equipment:
● Category (structural requirement)
● PL: Performance level
● MTTFd: Mean time to dangerous failure
● DC: Diagnostic coverage
● CCF: Common cause failure

The standard describes how the performance level (PL) is calculated for safety-related
components of the controller on the basis of designated architectures. In the event of any
deviations from this, EN ISO 13849-1:2006 refers to EN 61508.
When combining several safety-related parts to form a complete system, the Standard
explains how to determine the resulting PL.

Note
Since May 2007, EN ISO 13849-1:2006 has been harmonized as part of the Machinery
Directive. EN 954-1 will still apply until November 30, 2009.

8.1.2.5 EN 62061
EN 62061 (identical to IEC 62061) is a sector-specific standard subordinate to IEC/EN
61508. It describes the implementation of safety-related electrical machine control systems
and looks at the complete lifecycle, from the conceptual phase to decommissioning. The
standard is based on the quantitative and qualitative analyses of safety functions, whereby it
systematically applies a top-down approach to implementing complex control systems
(known as "functional decomposition"). The safety functions derived from the risk analysis
are sub-divided into sub-safety functions, which are then assigned to real devices, sub-
systems, and sub-system elements. Both the hardware and software are covered. EN 62061
also describes requirements regarding the implementation of application programs.
A safety-related control systems comprises different sub-systems. From a safety
perspective, the sub-systems are described in terms of the SIL claim limit and PFHD
characteristic quantities.
Programmable electronic devices (e.g. PLCs or variable-speed drives) must fulfill EN 61508.
They can then be integrated in the controller as sub-systems. The following safety-related
characteristic quantities must be specified by the manufacturers of these devices.
Safety-related characteristic quantities for subsystems:
● SIL CL: SIL claim limit
● PFHD: Probability of dangerous failures per hour
● T1: Lifetime
Simple sub-systems (e.g. sensors and actuators) in electromechanical components can, in
turn, comprise sub-system elements (devices) interconnected in different ways with the
characteristic quantities required for determining the relevant PFHD value of the sub-system.
Safety-related characteristic quantities for subsystem elements (devices):
● λ: Failure rate
● B10 value: For elements that are subject to wear
● T1: Lifetime
For electromechanical devices, a manufacturer specifies a failure rate λ with reference to the
number of operating cycles. The failure rate per unit time and the lifetime must be
determined using the switching frequency for the particular application.

Parameters for the sub-system, which comprises sub-system elements, that must be defined
during the design phase:
● T2: Diagnostic test interval
● β: Susceptibility to common cause failure
● DC: Diagnostic coverage
The PFHD value of the safety-related controller is determined by adding the individual PFHD
values for subsystems.
The user has the following options when setting up a safety-related controller:
● Use devices and sub-systems that already comply with EN ISO 13849-1:2006,
IEC/EN 61508, or IEC/EN 62061. The standard provides information specifying how
qualified devices can be integrated when safety functions are implemented.
● Develop own subsystems:
– Programmable, electronic systems and complex systems: Application of EN 61508 or
EN 61800-5-2.
– Simple devices and subsystems: Application of EN 62061.

EN 62061 does not include information about non-electric systems. The standard provides
detailed information on implementing safety-related electrical, electronic, and programmable
electronic control systems. EN ISO 13849-1:2006
must be applied for non-electrical systems.

Note
Details of simple sub-systems that have been implemented and integrated are now available
as "functional examples".

Note
IEC 62061 has been ratified as EN 62061 in Europe and harmonized as part of the
Machinery Directive.

8.1.2.6 Series of standards EN 61508 (VDE 0803)

This series of standards describes the current state of the art.
EN 61508 is not harmonized in line with any EU directives, which means that an automatic
presumption of conformity for fulfilling the protective requirements of a directive is not
implied. The manufacturer of a safety-related product, however, can also use EN 61508 to
fulfill basic requirements of European directives in accordance with the latest conceptual
design, for example, in the following cases:
● If no harmonized standard exists for the application in question. In this case, the
manufacturer can use EN 61508, although no presumption of conformity exists here.
● A harmonized European standard (e.g. EN 62061, EN ISO 13849:2006, EN 60204-1)
references EN 61508. This ensures that the appropriate requirements of the directives
are fulfilled ("standard that is also applicable"). When manufacturers apply EN 61508
properly and responsibly in accordance with this reference, they can use the presumption
of conformity of the referencing standard.

EN 61508 covers all the aspects that must be taken into account when E/E/PES systems
(electrical, electronic, and programmable electronic System) are used in order to execute
safety functions and/or to ensure the appropriate level of functional safety. Other hazards
(e.g. electric shock) are, like EN ISO 13849:2006, not part of the standard.
EN 61508 has recently been declared the "International Basic Safety Publication", which
makes it a framework for other, sector-specific standards (e.g. EN 62061). As a result, this
standard is now accepted worldwide, particularly in North America and in the automotive
industry. Today, many regulatory bodies already stipulate it (e.g. as a basis for NRTL listing).
Another recent development with respect to EN 61508 is its system approach, which extends
the technical requirements to include the entire safety installation from the sensor to the
actuator, the quantification of the probability of hazardous failure due to random hardware
failures, and the creation of documentation covering all phases of the safety-related lifecycle
of the E/E/PES.

8.1.2.7 Risk analysis/assessment

Risks are intrinsic in machines due to their design and functionality. For this reason, the
Machinery Directive requires that a risk assessment be performed for each machine and, if
necessary, the level of risk reduced until the residual risk is less than the tolerable risk. To
assess these risks, the following standards must be applied:
● EN ISO 12100-1 "Safety of Machinery - basic terminology, general principles for design"
● EN ISO 13849-1:2006 (previously EN 954-1) "Safety of machinery"
● EN ISO 14121-1 (previously EN 1050, Paragraph 5) "Safety of machinery - Risk
assessment"

EN ISO 12100-1 focuses on the risks to be analyzed and the design principles for minimizing
risk. EN ISO 14121-1 describes the iterative process for assessing and minimizing risk to
achieve the required level of safety.
The risk assessment is a procedure that allows hazards resulting from machines to be
systematically investigated. Where necessary, the risk assessment is followed by a risk
reduction procedure. When the procedure is repeated, this is known as an iterative process.
This can help eliminate hazards (as far as this is possible) and can act as a basis for
implementing suitable protective measures.
The risk assessment involves the following:
● Risk analysis
– Determining the limits of the machine (EN ISO 12100-1, EN ISO 14121-1 Paragraph 5)
– Identifying the hazards (EN ISO 12100-1, EN ISO 14121-1 Paragraph 6)
– Estimating the level of risk (EN 1050 Paragraph 7)
● Risk assessment (EN ISO 14121-1 Paragraph 8)

As part of the iterative process to achieve the required level of safety, a risk assessment is
carried out after the risk estimation. A decision must be made here as to whether the
residual risk needs to be reduced. If the risk is to be further reduced, suitable protective
measures must be selected and applied. The risk assessment must then be repeated.

Risks must be reduced by designing and implementing the machine accordingly (e.g. by
means of controllers or protective measures suitable for the safety-related functions).
If the protective measures involve the use of interlocking or control functions, these must be
designed in accordance with EN ISO 13849-1:2006. For electrical and electronic controls,
EN 62061 can be used as an alternative to EN ISO 13849-1:2006. Electronic controls and
bus systems must also comply with IEC/EN 61508.

8.1.2.8 Risk reduction

Risk reduction measures for a machine can be implemented by means of safety-related
control functions in addition to structural measures. To implement these control functions,
special requirements graded according to the magnitude of the risk must be taken into
account. These are described in EN ISO 13849-1:2006 or, in the case of electrical
controllers (particularly programmable electronics), in EN 61508 or EN 62061. The
requirements regarding safety-related controller components are graded according to the
magnitude of the risk and the level to which the risk needs to be reduced.
EN ISO 13849-1:2006 defines a risk graph, which can be used instead of the categories to
create hierarchical Performance Levels (PL).
IEC/EN 62061 uses "Safety Integrity Level" (SIL) for classification purposes. This is a
quantified measure of the safety-related performance of a controller. The required SIL is also
determined in accordance with the risk assessment principle to ISO 14121 (EN 1050). Annex
A of the standard describes a method for determining the required Safety Integrity Level (SIL).
Regardless of which standard is applied, steps must be taken to ensure that all the machine
controller components required for executing the safety-related functions fulfill these
requirements.

8.1.2.9 Residual risk

In today's technologically advanced world, the concept of safety is relative. In practice, the
ability to ensure safety to the extent that risk is permanently excluded – "zero-risk guarantee" –
is impossible. The residual risk is the risk that remains once all the relevant protective
measures have been implemented in accordance with the latest state of the art.
Machine/plant documentation must always refer to the residual risk (user information to
EN ISO 12100-2).

8.1.3 Machine safety in the USA

A key difference in the legal requirements regarding safety at work between the USA and
Europe is that, in the USA, no legislation exists regarding machinery safety that is applicable
in all of the states and that defines the responsibility of the manufacturers/supplier. A general
requirement exists stating that employers must ensure a safe workplace.

Function Manual, 11/2009, 6SL3097-4AB10-0BP1 331
Safety Integrated Functions
8.1 Standards and regulations

8.1.3.1 Minimum requirements of the OSHA

The Occupational Safety and Health Act (OSHA) from 1970 regulates the requirement that
employers must offer a safe place of work. The core requirements of OSHA are specified in
Section 5 "Duties".
The requirements of the OSH Act are managed by the "Occupational Safety and Health
Administration" (also known as OSHA). OSHA employs regional inspectors who check
whether or not workplaces comply with the applicable regulations.
The OSHA regulations are described in OSHA 29 CFR 1910.xxx ("OSHA Regulations (29
CFR) PART 1910 Occupational Safety and Health"). (CFR: Code of Federal Regulations.)
http://www.osha.gov
The application of standards is regulated in 29 CFR 1910.5 "Applicability of standards".
The concept is similar to that used in Europe. Product-specific standards have priority over
general standards insofar as they cover the relevant aspects. Once the standards are
fulfilled, employers can assume that they have fulfilled the core requirements of the OSH Act
with respect to the aspects covered by the standards.
In conjunction with certain applications, OSHA requires that all electrical equipment and
devices that are used to protect workers be authorized by an OSHA-certified, "Nationally
Recognized Testing Laboratory" (NRTL) for the specific application.
In addition to the OSHA regulations, the current standards defined by organizations such as
NFPA and ANSI must be carefully observed and the extensive product liability legislation
that exists in the US taken into account. Due to the product liability legislation, it is in the
interests of manufacturing and operating companies that they carefully maintain the
applicable regulations and are "forced" to fulfill the requirement to use state-of-the-art
technology.
Third-party insurance companies generally demand that their customers fulfill the applicable
standards of the standards organizations. Self-insured companies are not initially subject to
this requirement but, in the event of an accident, they must provide verification that they
have applied generally-recognized safety principles.

8.1.3.2 NRTL listing

To protect employees, all electrical equipment used in the USA must be certified for the
planned application by a "Nationally Recognized Testing Laboratory" (NRTL) certified by the
OSHA. NRTLs are authorized to certify equipment and material by means of listing, labeling,
or similar. Domestic standards (e.g. NFPA 79) and international standards (e.g. IEC/EN
61508 for E/E/PES systems) are the basis for testing.

 Safety Integrated Functions
8.1 Standards and regulations

8.1.3.3 NFPA 79
NFPA 79 (Electrical Standard for Industrial Machinery) applies to the electrical equipment of
industrial machines with rated voltages of less than 600 V A group of machines that operate
with one another in a coordinated fashion is also considered to be a machine.
For programmable electronics and communication buses, NFPA 79 states as a basic
requirement that these must be listed if they are to be used to implement and execute safety-
related functions. If this requirement is fulfilled, electronic controls and communication buses
can also be used for emergency stop functions, Categories 0 and 1 (refer to NFPA 79
9.2.5.4.1.4). Like EN 60204-1, NFPA 79 no longer specifies that the electrical energy must
be disconnected by electromechanical means for emergency stop functions.
The core requirements regarding programmable electronics and communication buses are:
system requirements (see NFPA 79 9.4.3)
1. Control systems that contain software-based controllers must:
– In the event of a single fault
(a) cause the system to switch to a safe shutdown mode
(b) prevent the system from restarting until the fault has been rectified
(c) prevent an unexpected restart
– Offer the same level of protection as hard-wired controllers
– Be implemented in accordance with a recognized standard that defines the
requirements for such systems.
2. IEC 61508, IEC 62061, ISO 13849-1/-2:2006, and IEC 61800-5-2 are specified as
suitable standards in a note.

Underwriter Laboratories (UL) has defined a special Category for "Programmable Safety
Controllers" for implementing this requirement (code NRGF). This category covers control
devices that contain software and are designed for use in safety-related functions.
A precise description of the category and a list of devices that fulfill this requirement can be
found on the Internet at the following address:
http://www.ul.com → certifications directory → UL Category code/ Guide information → search
for category "NRGF"

TUV Rheinland of North America, Inc. is also an NRTL for these applications.

8.1.3.4 ANSI B11

ANSI B11 standards are joint standards developed by associations such as the Association
for Manufacturing Technology (AMT) and the Robotic Industries Association (RIA).
The hazards of a machine are evaluated by means of a risk analysis/assessment. Risk
analysis is an important requirement in accordance with NFPA79, ANSI/RIA 15.06, ANSI
B11.TR-3 and SEMI S10 (semiconductors). The documented findings of a risk analysis can
be used to select a suitable safety system based on the safety class of the application in
question.

8.1.4 Machine safety in Japan

The situation in Japan is different from that in Europe and the US. Legislation such as that
prescribed in Europe does not exist. Similarly, product liability does not play such an
important role as it does in the US.
Instead of legal requirements to apply standards have been defined, an administrative
recommendation to apply JIS (Japanese Industrial Standard) is in place: Japan bases its
approach on the European concept and uses basic standards as national standards (see
table).

8.1.5 Equipment regulations

In addition to the requirements of the guidelines and standards, company-specific
requirements must be taken into account. Large corporations in particular (e.g. automobile
manufacturers) make stringent demands regarding automation components, which are often
listed in their own equipment specifications.
Safety-related issues (e.g. operating modes, operator actions with access to hazardous
areas, EMERGENCY STOP concepts, etc.) should be clarified with customers early on so
that they can be integrated in the risk assessment/risk reduction process.

8.2.1 Supported functions

This chapter covers all the Safety Integrated functions available for SINAMICS S110. A
distinction is made between Safety Integrated Basic Functions and Safety Integrated
Extended Functions.
The functions mentioned here comply with IEC 61508, SIL 2 for an operating mode with high
demand and Category 3, as well as with Performance Level d (PL d) in accordance with
ISO 13849-1 (formerly EN 954-1) and IEC 61800-5-2.
The following Safety Integrated (SI) functions are available:
● Safety Integrated Basic Functions
These functions are part of the standard scope of the drive.
– Safe Torque Off (STO)
STO is a safety function that prevents the drive from restarting unexpectedly, in
accordance with EN 60204-1:2006 Section 5.4.
– Safe Stop 1 (SS1, time controlled)
Safe Stop 1 is based on the "Safe Torque Off" function. This means that a Category 1
stop in accordance with EN 60204-1:2006 can be implemented.
– Safe Brake Control (SBC)
The SBC function permits the safe control of a holding brake.
A Safe Brake Relay is needed in addition for these functions.

● Safety Integrated Extended Functions

– Safe Stop 1 (SS1, time and acceleration controlled)
The SS1 function is based on the “Safe Torque Off” function. This means that a
Category 1 stop in accordance with EN 60204-1:2006 can be implemented.
– Safe Stop 2 (SS2)
The SS2 function brakes the motor safely with a subsequent transition to "Safe
Operating Stop" (SOS). This means that a Category 2 stop in accordance with EN
60204-1:2006 can be implemented.
– Safe Operating Stop (SOS)
"Safe Operating Stop" (SOS) protects against unintentional movements. The drive is
in closed-loop control mode and is not disconnected from the power supply.
– Safely Limited Speed (SLS)
The "Safely Limited Speed" (SLS) protects against excessively high drive speeds.
– Safe Speed Monitor (SSM)
The SSM function reliably monitors the speed limit and issues a safe output signal, but
without a response function.
– Safe Acceleration Monitor (SBR)
The Safe Acceleration Monitor function provides a safe method for monitoring drive
acceleration. It is part of functions SS1 and SS2.
– Safe Brake Ramp (SBR)
The Safe Brake Ramp function provides a safe method for monitoring the brake ramp.
It is part of the encoderless SS1 and encoderless SLS functions.

8.2.2 Control of Safety Integrated functions

Safety Integrated functions can be controlled via terminals or via a PROFIsafe telegram
using PROFIBUS. It is possible to select both terminals and PROFIsafe as control methods
at the same time.

NOTICE
PROFIsafe or terminals
With a Control Unit, either PROFIsafe or terminals can be used for control purposes. Mixed
operation is not permissible.

If induction motors are being used, certain Safety Integrated functions can also be used
without an encoder. During encoderless operation, actual speed values are based on the
actual electrical values measured. This means speed monitoring is possible during
encoderless operation up to n = 0 rpm.

8.2.3 Parameter, Checksum, Version, Password

Properties of Safety Integrated parameters

The following applies to Safety Integrated parameters:
● The Safety parameters are kept separate for each monitoring channel. With SINAMICS,
two channels are used to control Safety Integrated functions via a terminal on the Power
Module and one on the Control Unit. Tests are performed on both monitoring channels to
ensure they are working correctly.
● During startup, checksum calculations (Cyclic Redundancy Check, CRC) are performed
on the Safety parameter data and checked. The display parameters are not contained in
the CRC.
● Data storage: The parameters will be saved in the non-volatile memory.
● Factory settings for Safety parameters
A reset of the Safety parameters to the factory setting on a drive-specific basis using
p0970 or p3900 and p0010 = 30 is only possible when the safety functions are not
enabled (p9301 = p9501 = p9601 = p9801 = 0).
A complete reset of all parameters to the factory settings (p0976 = 1 and p0009 = 30 on
the Control Unit) is possible even when the safety functions are enabled (p9301 = p9501
= p9601 = p9801 ≠ 0).
● They are password-protected against accidental or unauthorized changes.

NOTICE
The following Safety parameters are not protected by the Safety password:
• p9370 SI Motion acceptance test mode (CPU 2)
• p9570 SI Motion acceptance test mode (CPU 1)
• p9533 SI Motion SLS Setpoint speed limitation
• p9705 BI: SI Motion Test stop signal source

Checking the checksum

For each monitoring channel, the Safety parameters include one parameter for the actual
checksum for the Safety parameters that have undergone a checksum check.
During commissioning, the actual checksum must be transferred to the corresponding
parameter for the reference checksum. This can be done for all checksums of a drive object
at the same time with parameter p9701.

Password
The Safety password protects the Safety parameters against unintentional or unauthorized
access.
In commissioning mode for Safety Integrated (p0010 = 95), you cannot change Safety
parameters until you have entered the valid Safety password in p9761 for the drive.
● When Safety Integrated is commissioned for the first time, the following applies:
– Safety passwords = 0
– Default setting for p9761 = 0
In other words:
The Safety password does not need to be set during first commissioning.
● In the case of a series commissioning of Safety or in the case of spare part installation,
the following applies:
– The Safety password is retained on the memory card and in the STARTER project.
– No Safety password is required in the case of spare part installation.
● Change password for the drive
– p0010 = 95 Commissioning mode
– p9761 = Enter "old Safety password".
– p9762 = Enter "new password".
– p9763 = Confirm "new password".
– The new and confirmed Safety password is valid immediately.
If you need to change Safety parameters but you do not know the Safety password, proceed
as follows:
1. Resetting the drive unit to factory settings.
2. Recommission the drive unit and drive.
3. Recommission Safety Integrated.

Or contact your regional Siemens office and ask for the password to be deleted (complete
drive project must be made available).

Machines and plants can only be operated safely in conjunction with Safety Integrated,
however, when the machine manufacturer
• is familiar with and observes every aspect of this technical user documentation,
including the documented general conditions, safety information, and residual risks.
• Carefully constructs and configures the machine/plant. A careful and thorough
acceptance test must then be performed by qualified personnel and the results
documented.
• Implements and validates all the measures required in accordance with the
machine/plant risk analysis by means of the programmed and configured Safety
Integrated functions or by other means.
It should be noted that Safety Integrated does not replace the machine/plant risk
assessment carried out by the machine manufacturer as required by the EG Machinery
Directive.
In addition to Safety Integrated, further risk reduction measures must be implemented.

WARNING
The Safety Integrated functions cannot be activated until the startup is completed. System
startup is a critical operating state with increased risk. No personnel may be present in the
immediate danger zone in this phase.
The drives of vertical axes must be in torque state.
A complete forced dormant error detection cycle is required after power on (see chapter
"Forced dormant error detection").

WARNING
EN 60204-1:2006
The EMERGENCY STOP function must be used to bring the machine to a standstill in
accordance with stop category 0 or 1 (STO or SS1).
The machine must not restart automatically after EMERGENCY STOP.
When the safety functions (Basic and Extended functions) are deactivated, an automatic
restart is permitted under certain circumstances depending on the risk analysis (except
when EMERGENCY STOP is reset). An automatic start is permitted when a protective door
is closed, for example.

WARNING
After hardware and/or software components have been modified or replaced, all protective
equipment must be closed prior to system startup and drive activation. Personnel shall not
be present within the danger zone.
It may be necessary to carry out a partial or complete acceptance test (see chapter
"Acceptance test") after having made certain changes or replacements.
Before allowing anybody to re-enter the danger zone, you should test steady control
response by briefly moving the drives in forward and reverse direction (+/–).
To observe during power on:
The safety functions can only be activated once system has booted up.

WARNING
• Encoder faults within a single-encoder system are detected by means of various HW
and SW monitoring functions. It is not allowed to disable these monitoring functions and
they must be parameterized carefully. Depending on the fault type and responding
monitoring function, stop function category 0 or 1 to EN 60204-1:2006 (fault response
functions STOP A or STOP B to Safety Integrated) is activated.
• Stop function category 0 to EN 60204-1:2006 (STO or STOP A to Safety Integrated)
means that the drives are not decelerate but instead coast to a standstill (the time
required to coast to standstill depends on the kinetic energy). This must be included in
the logic of the protective door lock, for example, by means of logic operation of SSM
(n<nx).
• Safety Integrated is not capable of detecting parameterization errors made by the
machine manufacturer. The required safety level can only be reached by by means of
an elaborate acceptance test.
• Power Modules or the motor must be replaced with a device of the same type, as the
parameter settings will otherwise lead to an incorrect Safety Integrated response.
The corresponding drive must be re-commissioned after an encoder was replaced.

WARNING
If an internal or external fault occurs, none or only some of the parameterized safety
functions are available during the STOP-F response triggered by the fault. This must be
taken into account when a delay time between STOP F and STOP B is parameterized.
This applies in particular to vertical axes.

8.3.3 Probability of failure for safety functions

Probability of failure
The probabilities of safety function failure must be specified in the form of a PHF value
(Probability of Failure per Hour) to IEC 61508, IEC 62061 and ISO 13849-1. The PFH value
of a safety function depends on the safety concept of the drive unit and its hardware
configuration, as well as on the PFH values of other components used for this safety
function.
Corresponding PFH values are provided for the SINAMICS S110 drive unit, depending on
the hardware configuration (control type, ...). The various integrated safety functions are not
differentiated.
The PHF values can be requested from your local sales office.

8.3.5 Residual risk

The fault analysis enables the machine manufacturer to determine the residual risk at his
machine with regard to the drive unit. The following residual risks are known:

WARNING
Due to the intrinsic potential of hardware faults, electrical systems are subject to additional
residual risk, which can be expressed by means of the PFH value.

WARNING
• Faults in the absolute track (C-D track), cyclic interchange of the drive phases (V-W-U
instead of U-V-W) and reversal of the control direction may cause acceleration of the
drive. Due to the fault, however, Category 1 and 2 stop functions to EN 60204-1:2006
(fault response functions STOP B to D in accordance with Safety Integrated) are not
activated.
Stop function Category 0 to EN 60204-1:2006 (fault response function STOP A in
accordance with Safety Integrated) is not triggered until after the transition or delay time
set in the parameter has elapsed. These faults are detected when SBR is selected (fault
reaction functions STOP B/C) and stop function category 0 to EN 60204-1:2006 (fault
reaction function STOP A in accordance with Safety Integrated) is triggered as early as
possible regardless of this delay. Electrical faults (defective components or similar) may
also lead to the response stated above.
• Simultaneous failure of two power transistors (one in the upper and the other offset in
the lower inverter bridge) in the inverter may cause brief movement of the drive,
depending on the number of poles of the motor.
Maximum value of this movement:
Synchronous rotary motors: Max. movement = 180° / no. of pole pairs

WARNING
• Violation of limits may briefly lead to a speed higher than the speed setpoint, or the axis
may pass the defined position to a certain extent, depending on the dynamic response
of the drive and on parameter settings.
• Mechanical forces greater than the maximum drive torque may force a drive currently
operated in position control mode out of Safe Operating Stop state (SOS) and trigger
stop function category 1 to EN 60204-1:2006 (fault reaction function STOP B).

8.3 System features

WARNING
Within a single-encoder system:
a) a single electrical fault in the encoder or
b) an encoder shaft breakage (or loose encoder shaft coupling), or a loose encoder housing
will cause a static state of the encoder signals (that is, they no longer follow a movement
while still returning a correct level), and prevent fault detection while the drive is in stop
state (for example, drive in SOS state).
Generally, the drive is held by the active closed-loop control. With closed loop control, it is
conceivable that vertical (suspended) drives in particular can move without their motion
being detected.
The risk of an electrical fault in the encoder as described under a) is only given for few
encoder types with specific function principle (for example, encoders with microprocessor
controlled signal generation such as the Heidenheim EQI, Hübner HEAG 159/160, or AMO
measuring systems with sin/cos signals).
The risk analysis of the machine manufacturer must include all of the faults described
above. Additional safety measures have to be taken for drives with suspended/vertical or
dragging loads in order to exclude the faults described in a). For example:
• Use of an encoder with analog signal generation
In order to exclude the fault described in b), for example:
• An FMEA regarding encoder shaft breakage (or slip of the encoder shaft coupling), and
a solution to prevent loose encoder housings, integration of a fault exclusion process to
CDV IEC 61800-5-2

8.4.1 Safe Torque Off (STO)

General description
In conjunction with a machine function or in the event of a fault, the "Safe Torque Off" (STO)
function is used to safely disconnect the torque-generating motor power supply.
When the function is selected, the drive unit is in a "safe status". The switching on inhibited
function prevents the drive unit from being restarted.
The two-channel pulse suppression integrated in the Power Modules is the basis for this
function.

Functional features of "Safe Torque Off"

● This function is integrated in the drive; this means that a higher-level controller is not
required.
● The function is drive specific, that is, it must be commissioned individually on a drive-by-
drive basis.
● The function must be enabled via parameter.
● When the "Safe Torque Off" function is selected:
– The motor cannot be started accidentally.
– The pulse suppression safely disconnects the torque-generating motor power supply.
– The power unit and motor are not electrically isolated.
● If STO is selected/deselected (and p9307.0/p9507.0 = 1 are set), safety messages, in
addition to fault messages, are also canceled automatically.

Function Manual
Function Manual, 11/2009, 6SL3097-4AB10-0BP1 349
Safety Integrated Functions
8.4 Safety Integrated Basic Functions

● The input terminals can be debounced to prevent signal faults triggering other faults.
Parameters p9651 and p9851 are used to set filter times.

WARNING
Appropriate measures must be taken to ensure that the motor does not move once the
motor power supply has been disconnected ("coast down") (e.g. enable the "Safe Brake
Control" function with a vertical axis).

CAUTION
If two power transistors in the power unit (one in the upper and one offset in the lower
inverter bridge) break down at the same time, this can cause a limited momentary
movement.
The maximum movement for synchronous rotary motors can be = 180 ° / pole pair
number

● The status of the "Safe Torque Off" function is displayed using parameters.

Enabling the "Safe Torque Off" (STO) function

The "Safe Torque Off" function is enabled via the following parameters:

NOTICE
It is not possible to activate the control via safety terminals and PROFIsafe at the same
time.

● STO via on-board terminals (F-DI 0, Basic Functions):

– p9601.0 = 1, p9801.0 = 1

Selecting/deselecting "Safe Torque Off"

The following occurs when "Safe Torque Off" is selected:
● Each monitoring channel triggers safe pulse suppression via its switch-off signal path.
● A motor holding brake is applied (if connected and configured).
If "Safe Torque Off" is deselected, this is treated as an internal safe acknowledgment.
The following processes occur:
● Each monitoring channel cancels safe pulse suppression via its switch-off signal path.
● The safety prompt "Apply motor holding brake" is canceled.
● Any pending STOP F or STOP A commands are canceled (see r9772/r9872).
● The cause of the fault must be remedied.
● The messages in the fault memory also need to be reset using the general
acknowledgment mechanism.

Note
If "Safe Torque Off" is selected and deselected again through one channel within the time
in p9650/p9850, the pulses are canceled but no message is output.
If you want a message to be displayed in this case, however, you have to reconfigure
N01620/N30620 via p2118 and p2119 as an alarm or fault.

Restart after the "Safe Torque Off" function has been selected
1. Deselect the function in each monitoring channel via the input terminals.
2. Set drive enables.
3. Cancel the "switching on inhibited" and switch the drive back on.
– 1/0 edge at input signal "ON/OFF1" (cancel "switching on inhibited")
– 0/1 edge at input signal "ON/OFF1" (switch on drive)
4. Run the drives again.

Status for "Safe Torque Off"

The status of the "Safe Torque Off" (STO) function is displayed via parameters r9772, r9872,
r9773, and r9774.
As an alternative, the status of the function can be displayed using the configurable
messages N01620 and N30620 (configured using p2118 and p2119).

8.4.2 Safe Stop 1 (SS1, time controlled)

General description
A Category 1 stop in accordance with EN 60204-1:2006 can be implemented with function
"Safe Stop 1". The drive decelerates with the OFF3 ramp (p1135) once "Safe Stop 1" is
selected and switches to "Safe Torque Off" once the delay time set in p9652/p9852 has
elapsed.

CAUTION
Once the SS1 (time-controlled) function has been selected by parameterizing a delay in
p9652/p9852, STO can no longer be selected directly via terminals.

Functional features of "Safe Stop 1"

SS1 is selected by setting p9652 and p9852 (delay time) not equal to "0"
● The settings for parameters p9652/p9852 shown below have the following effect:
– p9652/p9852 = 0: STO active
– p9652/p9852 > 0: SS1 active
● When SS1 is selected, the drive is braked along the OFF3 ramp (p1135) and STO/SBC is
automatically initiated after the delay time has expired (p9652/p9852).
As soon as the function is selected, the delay time will start to run down - even if the
function is deselected during this time. In this case, after the delay time has expired, the
STO/SBC function is selected and then again de-selected immediately.
● The selection is realized through two channels - however braking along the OFF3 ramp,
only through one channel.
● The input terminals can be debounced to prevent signal faults triggering other faults.
Parameters p9651 and p9851 are used to set filter times.

Enabling function Safe Stop 1

The "Safe Stop 1" (SS1) function is enabled via the following parameters:
● SS1 via terminals or PROFIsafe:
– By entering the delay time in p9652 and p9852

Prerequisite
The "Safe Torque Off" function must be enabled.
In order that the drive can brake down to a standstill even when selected through one
channel, the time in p9652/p9852 must be shorter than the sum of the parameters for the
data cross-check (p9650/p9850 and p9658/p9858).
The time in p9652/p9852 must be dimensioned so that after selection, the drive brakes to a
standstill.

8.4.3 Safe Brake Control (SBC)

Description
The "Safe Brake Control" function (SBC) is used to control holding brakes that function
according to the quiescent current principle (e.g. motor holding brakes).
The command for releasing or applying the brake is transmitted to the Safe Brake Relay via
the Power Module. The Safe Brake Relay then carries out the action and activates the
outputs for the brake accordingly.
Brake activation via the brake connection on the Safe Brake Relay is carried out using a
safe, two-channel method.

Note
This function can only be used for Power Modules blocksize if a Safe Brake Relay is used
(for more information, see Equipment Manual GH6).
When the Power Module is configured automatically, the Safe Brake Relay is detected and
the motor holding brake type is defaulted (p1278 = 0).

WARNING
"Safe Brake Control" does not detect faults in the brake itself, such as brake winding short-
circuit, worn brakes, etc.
If a cable breaks, this is only recognized by the "Safe Brake Control" function when the
status changes, i.e. when the brake is applied/released.

Functional features of "Safe Brake Control" (SBC)

● When "Safe Torque Off" is selected or when safety monitors are triggered, "SBC" is
performed with safe pulse suppression.
● Unlike conventional brake control, SBC is executed via p1215 through two channels.
● SBC is executed regardless of the brake control or mode set in p1215. SBC is not
recommended, however, when 1215 = 0 or 3.
● The function must be enabled via parameter.
● When SBC is enabled, the holding brake is applied immediately with forced dormant error
detection each time "Safe Torque Off" is selected.
● Electrical faults (e.g. brake winding short-circuits or wire breaks) can be detected during
status changes.
● The input terminals can be debounced to prevent signal faults triggering other faults.
Parameters p9651 and p9851 are used to set filter times.

Enabling the "Safe Brake Control (SBC)" function

The "Safe Brake Control" function is enabled via the following parameters:
● p9602 SI enable safe brake control (CPU 1)
● p9802 SI enable safe brake control (CPU 2)
The "Safe Brake Control" function is not selected until at least one safety monitoring function
has been enabled (i.e. p9601 = p9801 ≠ 0).

Two-channel brake control

The function "Safe Brake Control" is carried out using a two-channel method, in which both
the plus-potential (24 V) leading and the ground-potential leading brake connection are
connected to the Safe Brake Relay.
The brake diagnosis can only reliably detect a malfunction in either of the switches in the
Safe Brake Relay when the status changes (when the brake is released or applied).
If the Safe Brake Relay or its controller detects a fault, the brake current is switched off and a
safe status is reached.

Response time with the "Safe Brake Control" function

For the response times when the function is selected/deselected via input terminals, see the
table in "Response times".

Example
Assumption:
Safety monitoring clock cycle time CU (r9780) = 2 ms and
inputs/outputs sampling time = 4 ms
tR_typ = 4 x r9780 (2 ms) + 4 ms = 12 ms
tR_max = 8 x r9780 (2 ms) + 4 ms = 20 ms

NOTICE
When controlling the brake via a relay using "Safe Brake Control":
A relay cannot be used to apply the brake if "Safe Brake Control" is being used. This would
cause a brake fault to be fed back in error.

holding brake (not a safety brake!) with sufficient holding force.

Acknowledging the safety faults

Faults associated with Safety Integrated Basic Functions must be acknowledged as follows:
1. Remove the cause of the fault.
2. Deselect "Safe Torque Off" (STO).
3. Acknowledge the fault.
If safety commissioning mode is exited when the safety functions are switched off (p0010 ≠ 95
when p9601 = p9801 = 0), all the safety faults can be acknowledged.
Once safety commissioning mode has been selected again (p0010 = 95), all the faults that
were previously present reappear.

NOTICE
Safety faults can also be acknowledged (as with all other faults) by switching the drive unit
off and then on again (POWER ON).
If this action has not eliminated the fault cause, the fault is displayed again immediately
after power up.

Acknowledgment via PROFIsafe

The higher-level controller sets the signal "Internal Event ACK" via the PROFIsafe telegram
(STW bit 7). A falling edge in this signal resets the status "Internal Event" and so
acknowledges the fault.
Acknowledgment via F-DI
If the signal "Internal Event ACK" is connected with an F-DI, a falling edge in this signal
resets the status "Internal Event" and so acknowledges the fault. For safety reasons, the
external signal on the F-DI with the "Internal Event ACK" function must not be set
continuously to the "1" level; for acknowledgment, it must first be set from the idle state "0" to
"1" and then back to "0" again.

8.4.5 Forced dormant error detection

Forced dormant error detection or test of the switch-off signal paths for Safety Integrated Basic
Functions
The forced dormant error detection function at the switch-off signal paths is used to detect
software/hardware faults at both monitoring channels in time and is automated by means of
activation/deactivation of the "Safe Torque Off" function.
To fulfill the requirements of ISO 13849-1 (2006) regarding timely error detection, the two
switch-off signal paths must be tested at least once within a defined time to ensure that they
are functioning properly. This functionality must be implemented by means of forced dormant
error detection function, triggered either in manual mode or by the automated process.
A timer ensures that forced dormant error detection is carried out as quickly as possible.
● p9659 SI timer for the forced dormant error detection.
Forced dormant error detection must be carried out at least once during the time set in this
parameter.
Once this time has elapsed, an alarm is output and remains present until forced dormant
error detection is carried out.
The timer returns to the set value each time the STO function is deactivated.
When the appropriate safety devices are implemented (e.g. protective doors), it can be
assumed that running machinery will not pose any risk to personnel. For this reason, only an
alarm is output to inform the user that a forced dormant error detection run is due and to
request that this be carried out at the next available opportunity. This alarm does not affect
machine operation.
The user must set the time interval for carrying out forced dormant error detection to
between 0.00 and 9000.00 hours depending on the application (factory setting: 8.00 hours).
Examples of when to carry out forced dormant error detection:
● When the drives are at a standstill after the system has been switched on (POWER ON).
● When the protective door is opened.
● At defined intervals (e.g. every 8 hours).
● In automatic mode (time and event dependent).

NOTICE
The timer of the Basic Functions will be reset if the associated forced dormant error
detection is executed and the Extended Functions are used simultaneously.
The corresponding alarm of the Basic Functions is not triggered.
Discrepancy is not checked at the terminals used to select the Basic Functions as long as
STO is set by the Extended Functions. That is, the forced dormant error detection
procedure of the Basic Functions always has to be executed without simultaneous selection
of STO or SS1 by the Extended Functions. It is otherwise not possible to verify the correct
control through the terminals.

8.5.1 Parking note

Note
When a drive object for which Safety Integrated Extended Functions are enabled is switched
to "Park" mode, the Safety Integrated software responds by selecting STO without
generating a separate message. This internal STO selection is displayed in parameter
r9772.19.

8.5.2 Safe Torque Off (STO)

8.5.2.1 Safe Torque Off with encoder

As far as Safety Integrated Extended Functions are concerned, "Safe Torque Off" (STO) with
encoder is controlled in exactly the same way as it is for Safety Integrated Basic Functions.
The function involved is described in the "Safety Integrated Basic Functions" chapter.

8.5.2.2 Encoderless Safe Torque Off

Safe Torque Off without encoder

If an induction motor is being used, Safe Torque Off (STO) can also be used without an
encoder.

Function
Set p9306 = p9506 = 1 (factory setting = 0) to activate encoderless Safety Integrated
functions. You can also make this setting by selecting "Without encoder" on the safety
screen.

Difference between Safe Torque Off with and without an encoder

Depending on whether or not it has an encoder, STO demonstrates different restart behavior
in terms of SLS after STO/OFF2 (see the "Encoderless SLS Safely-Limited Speed" chapter).

Functional features of "Safe Stop 1"

● The delay time starts after the function has been selected. If SS1 is deselected again
during this time, the STO function is selected and deselected again straightaway after the
delay time has elapsed or the speed has dropped below the shutdown speed.
● The selection is realized through two channels - however braking along the OFF3 ramp,
only through one channel.
● The "Safe Acceleration Monitor" (SBR) function is selected during braking (see "Safe
Acceleration Monitor").

Function Manual
Function Manual, 11/2009, 6SL3097-4AB10-0BP1 361
Safety Integrated Functions
8.5 Safety Integrated Extended Functions

Note
Activating SS1 may cause the device (PLC, motion controller) that governs the speed
setpoint to interrupt the ramp function by triggering OFF2.
The device behaves in this way as a result of a fault reaction triggered by OFF3 activation.
This fault reaction can be avoided by carrying out appropriate parameterization or wiring
work, whereby the device will be informed when SS1 is triggered.

Note
If you are using SS1 in an EPOS application, OFF2 is not permitted as a fault reaction to a
following error.

Commissioning
The function is selected by entering the delay time in p9356 and p9556. The wait time before
the pulse is suppressed can be shortened by defining a shutdown speed in p9360 and
p9560.
To enable the drive to decelerate to standstill after selection, the time set in p9356/p9556
must be sufficient to allow the drive to decelerate to below the shutdown speed in
p9360/p9560 with the OFF3 ramp (p1135).
When setting a shutdown speed in p9360/p9560, you must be certain that the safety of
personnel or machinery will not be compromised at speeds less than or equal to this speed
or as a result of subsequent coasting caused by the pulse inhibit.

Responses
Speed limit violated (SBR):
● STOP A
● Safety message C01706/C30706
System errors:
1. STOP F with subsequent STOP A
2. Safety message C01711/C30711

Prerequisite
The time set in p9356/9556 must be dimensioned so that after selection, the drive brakes
down to a standstill.

Status for "Safe Stop 1"

The status of the "Safe Stop 1" function is displayed using the following parameters:
● r9722.1 CO/BO: SI Motion status signals, SS1 active
● r9722.0 CO/BO: SI Motion status signals, STO active (power removed)

8.5.3.2 Encoderless Safe Stop 1 (time and speed controlled)

If an induction motor is being used, the "Safe Stop 1" (SS1) Safety Integrated function can
also be activated without an encoder.

Function
The motor is immediately decelerated along the OFF3 ramp (OFF3 ramping) as soon as
SS1 is triggered. Monitoring is activated once the delay time in p9582/p9382 has elapsed
(SBR delay time). Monitoring ensures that the motor does not exceed the set braking ramp
(envelope (monitoring ramp)) during braking. As soon as the speed drops below the
shutdown speed (p9560/p9360; standstill detection), safe monitoring of the brake ramp is
deactivated and safe pulse suppression (STO) is activated.

Safety Integrated Functions
8.5 Safety Integrated Extended Functions

Difference between Safe Stop 1 with and without an encoder

The SS1 function with an encoder monitors whether motor acceleration reaches
impermissible levels during the SS1 time. If the drive complies with acceleration monitoring
limits, STO is triggered when the shutdown speed is reached. If acceleration monitoring
limits are violated, messages C01706 and C30706 are output and the drive is stopped with
STOP A. If the motor does not reach the shutdown speed within the set braking time, STO is
still triggered and the drive coasts to a standstill. No message is issued.
The SS1 function without an encoder is a monitoring facility for ensuring the motor does not
exceed the set brake ramp. STO is triggered when the speed drops below the shutdown
speed. If the set brake ramp is violated (exceeded), messages C01706 and C30706 are
output and the drive is stopped with STO (STOP A).

Parameterization of the encoderless brake ramp

p9581/p9381 and p9583/p9383 are used to set the steepness of the brake ramp.
Parameters p9581/p9381 determine the reference speed and parameters p9583/p9383
define the monitoring period. Parameters p9582/p9382 are used to set the time between the
triggering of Safe Stop 1 and the start of brake ramp monitoring.

8.5.4 Safe Stop 2 (SS2)

8.5.4.1 Safe Stop 2

Description
The "Safe Stop 2" (SS2) safety function is used to brake the motor safely on the OFF3 ramp
down (p1135) with subsequent transition to the SOS state (see the "Safe Operating Stop"
chapter) after the delay time expires (p9352/p9552). The delay time set must allow for the
drive to brake down to a standstill within this time. The standstill tolerance (p9330/p9530)
may not be violated after this time.
After the braking operation is completed, the drives remain in speed control mode with speed
setpoint n = 0.
The "Safe Stop 2" (SS2) safety function can only be used with an encoder.

WARNING
When SS2 is used, the full rated voltage (VDC link) is applied to the motor, which is
energized.

The setpoint input (e.g. from the setpoint channel, or from a higher-level control) remains
inhibited as long as SS2 is selected. The "Safe Acceleration Monitor" (SBR) function is
selected during braking.

function is triggered. When making the settings under p2573 (maximum deceleration) and
p2645 (deceleration override) for the deceleration caused by EPOS, it is essential to ensure
the drive can be stopped within the delay time for SOS activation → SOS active

8.5.5 Safe Operating Stop (SOS)

Description
This function serves for failsafe monitoring of the standstill position of a drive.
Personnel can enter the protected machine areas without having to shut down the machine
as long as SOS is active.
Drive standstill is monitored by means of an SOS tolerance window (p9330 and p9530).
The SOS function is activated after SOS is selected and when the delay time set in
p9351/p9551 expires. The drive must be braked to standstill within this delay time (e.g. by
the controller). When this function is activated, the current actual position is saved as a
comparative position until SOS is deselected again. Any delay time is cleared after SOS is
canceled and the drive can start up immediately.

● The drive remains in the closed-loop control mode.
● A programmable standstill tolerance window is available.

8.5.6 Safely Limited Speed (SLS)

The Safely Limited Speed (SLS) function is used to protect a drive against unintentionally
high speeds. This is achieved by monitoring the current drive speed up to a speed limit.
Safely Limited Speed prevents a parameterized speed limit from being exceeded. Limits
must be specified based on results of the risk analysis. Up to 4 different SLS speed limits
can be parameterized via parameter p9531[0..3].

8.5.6.1 Safely Limited Speed with encoder

Features
● A selected speed limit is activated once SLS has been selected and after the delay time
(p9351/p9551) has elapsed. When switching to a lower speed limit, the speed must be
decelerated below the new maximum limit within this delay time.
● If the actual speed is higher than the new speed limit after the delay time has elapsed, a
message is created with the parameterized stop response.
● Stop responses are parameterized via p9363/p9563.
● During changeover to a higher speed limit, the delay time does not take effect.
● 4 parameterizable speed limits p9331[0...3] and p9531[0...3]

limits on the load side.

Changeover of speed limits

The changeover is controlled by means of binary signals from two F-DIs. The speed
selection status can be checked using the r9720.9/r9720.10 parameters. Parameters
r9722.9 and r9722.10 indicate the actual speed limit, bit r9722.4 must carry a "1" signal.

Table 8- 8 Changeover of speed limits:

F-DI for bit 0 (r9720.9) F-DI for bit 1 (r9720.10) Speed limit
0 0 p9331[0]/p9531[0]
0 1 p9331[1]/p9531[1]
1 0 p9331[2]/p9531[2]
1 1 p9331[3]/p9531[3]
The changeover from a lower to a higher speed limit takes effect without any delay.
The changeover from a higher to a lower limit triggers a delay time which can be set at the
corresponding parameter (p9351 and p9551).
To ensure that the drive reaches the reduced speed below the new speed limit value once
the delay time has elapsed, it must be decelerated accordingly within the delay time by
means of the higher-level motion control/setpoint channel. However, if the actual speed is
higher than the new limit value and the time has expired, an appropriate alarm with the
configured stop response will be generated.

CAUTION
SLS level 1 must be defined as the lowest speed limit.
SLS level 1 is activated after two unacknowledged discrepancy errors; in other words, 0 is
the failsafe value for the 2 F-DIs for speed level selection. The SLS levels to be switched
between should, therefore, always be parameterized in ascending order, i.e. with SLS level
1 as the lowest speed and SLS level 4 as the highest.

● Configured subsequent stop STOP A / B / C / D by means of p9363/p9563

8.5.6.2 Encoderless Safely Limited Speed

If an induction motor is being used, Safely Limited Speed (SLS) can also be activated
without an encoder.

Features
After SLS has been triggered, measures should be taken to ensure the motor is immediately
decelerated with the OFF3 ramp from the current speed to below the selected SLS [1...4]
speed limit. Monitoring is activated after delay time p9582/p9382 (SI Motion brake ramp
delay time Control Unit/Motor Module) has elapsed. Monitoring ensures the motor does not
exceed the set brake ramp (SBR) during braking.
The new SLS speed limit is accepted as the new limit speed if either the brake ramp has
reached the new SLS speed limit or the actual speed of the drive was below the new SLS
speed limit for at least as long as p9582 (SI Motion brake ramp delay time Control Unit).
The SLS function then monitors whether the new actual speed remains below the selected
SLS speed limit. The programmed STOP response is triggered as soon as the limit speed is
exceeded.

Configuring the limits

Speed limits for encoderless SLS are configured in exactly the same way as described for
SLS with an encoder.

Differences between SLS with and without an encoder

The SLS with encoder function monitors whether the motor remains under the set limit
speed. During deceleration to a lower limit speed, SBR also monitors whether the drive has
dropped below the lower limit speed within the delay time specified. If this is not the case,
messages C01714 and C30714 are output.
The SLS without encoder function monitors whether the motor remains under the set limit
speed during operation. During deceleration to a lower limit speed, SLS acts as a monitor to
ensure the motor does not exceed the set brake ramp. If the brake ramp is violated,
messages C01707 and C30707 are output and the drive is stopped with STOP A or STOP B
(depending on the setting made).

2nd scenario:
● Switch-on status: Encoderless SLS selected, STO selected, OFF2 active
● Deselect STO.
● Unless there is a drive enable via a positive edge at OFF1 within 5 seconds, a safety fault
will be output as speed monitoring will be impossible.
3rd scenario:
● Switch-on status: Encoderless SLS selected, STO not selected, OFF2 active
● Unless there is a drive enable via a positive edge at OFF1 within 5 seconds after ramping
up is complete, a safety fault will be output as speed monitoring will be impossible.

Parameterization of the encoderless brake ramp

p9581/p9381 and p9583/p9383 are used to set the steepness of the brake ramp.
Parameters p9581/p9381 determine the reference speed and parameters p9583/p9383
define the monitoring period. Parameters p9582/p9382 are used to set the time between the
triggering of Safe Stop 1 and the start of brake ramp monitoring.

8.5.6.3 EPOS and Safely-Limited Speed

When using the EPOS positioning function, if a Safely-Limited Speed monitoring (SLS) is to
be used at the same time, then EPOS must be informed about the activated speed
monitoring limit, as otherwise this can be violated by the setpoint input from EPOS. Further,
this violation can cause the SLS monitoring to stop the drive - therefore interrupting the
intended motion sequence.
With its parameter p9733, the SLS function provides a setpoint limit value which, when taken
into account, prevents the SLS limit value from being violated.
This means that the setpoint limit value in p9733 must therefore be transferred to the input
for the maximum setpoint speed/velocity of EPOS (p2594) in order to prevent an SLS limit
value violation as a result of the EPOS setpoint input.

Overview of important parameters (see SINAMICS S110 List Manual)

● p2594 CI: EPOS maximum speed externally limited

8.5.7 Safe Speed Monitor (SSM)

Description
The "Safe Speed Monitor" (SSM) function provides a reliable method for indicating when a
speed limit has been undershot (p9346/p9546) (e.g. for standstill detection) in both
directions. A failsafe output signal is available for further processing.
The function is activated automatically as soon as the Extended Functions are enabled with
p9301.0 = p9501.0 = 1.

NOTICE
If 0 is entered for p9368/p9568, the speed limit of the SSM function (p9346/p9546) is also
used as the shutdown limit for the SBR function (safe acceleration monitoring) when the
shutdown speed for SBR is set to 0 (see also the chapter titled "Safe Brake Ramp").
This means the effects of safe acceleration monitoring are restricted if a relatively high
SSM/SBR speed limit is set when using the SS1 and SS2 stop functions.

WARNING
STOP F (indicated by fault C01711/C30711) only results in a follow-up response (STOP
B/STOP A) if at least one of the safety functions (SOS or SLS) is active or has been
selected. If only the SSM function is active, a STOP F crosswise comparison error does not
result in a follow-up response (STOP B/STOP A).
If SSM is to be used as a safety function, at least one of the SOS or SLS functions must be
active/selected (e.g. by selecting a high SLS level).

Functional features of "Safe Speed Monitor"

Parameter p9346/p9546 "SI Motion SSM (SGA n < nx) speed limit n_x (CU)" is used to set
the speed limit. The abbreviation "SGA n < nx" indicates the safety function required for
determining an output signal when a parameterizable velocity limit has been undershot.
If the velocity limit for the "Safe Speed Monitor" feedback signal (n < n_x) for detecting
standstill is undershot, the "SSM feedback signal active" signal (SGA n < n_x) is set. When
the set threshold value has been undershot, the "Safe Acceleration Monitor" (SBR) function
is also deactivated (see p9368/p9568). If p9368 = p9568 = 0, p9346/p9546 (SSM feedback
signal) is also used for safe acceleration monitoring for SBR.
The hysteresis for the SSM output signal is set in parameter p9347/p9547 "SI Motion velocity
hysteresis (crosswise)". If the maximum permissible velocity tolerance is overshot (i.e. one
channel displays a velocity less than p9546 - p9547, while the other channel displays a
velocity greater than p9546), a Stop F is issued. Parameters p9347/p9547 provide an
additional function by defining the maximum tolerance for the actual speed values between
the two channels.

376 Function Manual, 11/2009, 6SL3097-4AB10-0BP1
 Safety Integrated Functions
8.5 Safety Integrated Extended Functions

In addition, the output signal for SSM can be smoothed via a PT1 filter by setting a filter time
of p9345/9545 "SI Motion filter time nx".
During safe motion monitoring, the hysteresis and filtering functions can be activated or
deactivated jointly by means of an enabling bit (p9301.16 (Motor Modules) and p9501.16
(CU)). In the default setting, the functions are deactivated (p9301.16/p9501.16 = 0).

NOTICE
Exception
The activated "hysteresis and filtering" function is treated as an activated monitoring
function and results in the STOP B/STOP A follow-up response after a STOP F.

The following diagram shows the characteristic of the safe output signal SSM when the
hysteresis is active:

660RXWSXWVLJQDO


Q>PPPLQ@

S SS SS S

Figure 8-9 Safe output signal for SSM with hysteresis

Due to the hysteresis, the safe output signal for SSM can also lie above the parameterized
velocity limit at 1.

Note
When hysteresis and filtering is activated with output signal SSM, the axes behave in a time-
delayed manner. This is a characteristic of the filter.

8.5.8 Safe Acceleration Monitor (SBR)

Safe Acceleration Monitor with encoder

The "Safe Acceleration Monitor" (SBR) function is used for safe monitoring of drive
acceleration. This function is part of the SS1 (time and acceleration controlled) and SS2 (or
STOP B and STOP C) Safety functions.

Functional features
A STOP A is generated if any drive acceleration within the ramp-down phase exceeds the
tolerance defined in p9348/p9548. The monitoring function is activated after SS1 (or STOP
B) and SS2 (or STOP C) are set and is deactivated after the speed drops below the value
set in p9346/p9546.

NOTICE
If 0 is entered for p9368/p9568, the speed limit of the SSM function (p9346/p9546) is also
used as shutdown limit for the SBR function (safe acceleration monitoring). The SBR is
deactivated if the speed is below this limit.
This means the effects of safe acceleration monitoring are greatly restricted if a relatively
high SSM/SBR speed limit is set when using the SS1 and SS2 stop functions.

Calculating SBR tolerance of the actual speed

● The following rules are valid for the parameterization of SBR tolerance:
– The maximum speed increase after SS1 / SS2 is triggered is derived from the
effective acceleration (a) and the duration of the acceleration phase.
– The duration of the acceleration phase is equivalent to one monitoring clock cycle
(p9300/p9500) MC (delay from detecting an SS1 / SS2 until nset = 0):
● SBR tolerance
Actual speed SBR = acceleration * acceleration duration
The following setup rule is derived thereof:
– At linear axes:
SBR tolerance [mm/min] = a [m/s2] * MC [s] * 1000 [mm/m] * 60 [s/min]
– At rotary axes:
SBR tolerance [rpm] = a [rev/s2] * MC [s] * 60 [s/min]
● Recommendation:
The SBR tolerance value entered should be approx. 20% higher than the calculated
value.

Responses

8.5.9 Safe Brake Ramp (SBR)

If an induction motor is being used, the "Safe Brake Ramp" (SBR) Safety Integrated function
can be activated without an encoder. The Safe Brake Ramp (SBR) function provides a safe
method for monitoring the brake ramp. The Safe Brake Ramp function, safe brake ramp
monitoring (SBR) is always used to monitor braking when using the SS1 encoderless and
SLS encoderless functions.

Functional features of Safe Brake Ramp without encoder

The motor is immediately decelerated along the OFF3 ramp as soon as SS1 or SLS is
triggered. Monitoring of the brake ramp (envelope (monitoring ramp)) is activated after delay
time p9582/p9382 (SI Motion brake ramp delay time (SBR delay time), Control Unit/Motor
Module) has elapsed. Monitoring ensures that the motor does not exceed the set brake ramp
(SBR) when braking. As soon as the speed drops below the shutdown speed (p9560/p9360;
standstill detection), safe monitoring of the brake ramp is deactivated. Additional specific
functions (e.g. STO, new SLS speed limit, etc.) are activated at this point, depending on the
Safety Integrated function used

of tD. SOS is activated on expiration of the
time tD.
An automatic response is only
triggered if the standstill tolerance
window is violated in SOS.

Note
A delay time between STOP F and STOP B should only be set if an additional response is
initiated during this time when the "Internal Event" (p9722.7) message signal is evaluated.
A monitoring function should also always be active even in automatic mode (e.g. SLS with a
high limit speed) when the delay time is used.
An activated hysteresis for SSM should be regarded as an activated monitoring function.

priority
1) The SOS monitoring function remains active, but the fault response in the event of a fault can no longer be triggered
because it is already present.
2) Stop B is the follow-up stop of Stop F, which is activated after a parameterizable time. Stop F alone does not have any
effect; the active safety function is still present.
3) The SLS monitoring function remains active, although the fault response in the event of a fault can no longer be
triggered because it is already present.
4) SLS remains active during the braking phase, after which the system switches to SOS.

The table above specifies which stop response / safety function is set when a stop is
triggered when a safety function is active. The stops are arranged here from left to right in
descending order of priority (stop A to F).
No overall priority is assigned in the individual safety functions. SOS remains active, for
example, even if STO is requested. The safety functions that cause the drive to decelerate
(STO, SS1, SS2) are specified from top to bottom in descending order of priority.
If a field contains two entries, the stop responses and safety functions have the same
priority. Explanation:
● Stop A is equivalent to STO
● Stop B is equivalent to SS1
● Stop C is equivalent to SS2
● When the SS2 function is active, stop F results in follow-up stop B. SS2 remains active.

Examples for illustrating the information in the table:

1. Safety function SS1 has just been selected. Stop A remains active; a stop B operation
that is currently in progress is not interrupted by this. The remaining stop functions (stops
C to F) are replaced by SS1.
2. The SLS safety function is selected. This does not alter the function of stops A to D.
Stop F now triggers a stop B because a safety function has been activated.
3. Stop response C is activated. If the STO or SS1 safety functions are active, this does not
have any effect. If SS2 is active, this braking ramp is retained. If SOS is active, SOS
remains effective, which is also the end status of stop C. When SLS is selected, the drive
is decelerated with Stop C.

Acknowledging the safety faults

NOTICE
Safety faults can also be acknowledged (as with all other faults) by switching the drive unit
off and then on again (POWER ON).
If this action has not eliminated the fault cause, the fault is displayed again after power up..

Acknowledgment via PROFIsafe

The higher-level controller sets the signal "Internal Event ACK" via the PROFIsafe telegram
(STW bit 7). A falling edge in this signal resets the status "Internal Event" and so
acknowledges the fault.
Acknowledgment via F-DI
If the signal "Internal Event ACK" is connected with an F-DI, a falling edge in this signal
resets the status "Internal Event" and so acknowledges the fault. For safety reasons, the
external signal on the F-DI with the function "Internal Event ACK" may not be kept
continuously on the "1" level or for acknowledgment it must first be set from the idle state "0"
to "1" and then set back to "0" once more.

When a safety message is present, the bit 2139.5 = 1 ("Safety message present") is set.
The entry in the message buffer is delayed. For this reason, the message buffer should not
be read until a change in the buffer (r9744) has been detected after "Safety message
present" is output.
The messages must be acknowledged via the failsafe inputs F-DI or via PROFIsafe.

Properties of the message buffer:

● A new message case comprises one or more messages and is entered in the "Current
message case".
● The entries appear in the buffer according to the time at which they occurred.
● If a new message case occurs, the message buffer is reorganized accordingly.
The history is recorded in "Acknowledged message case" 1 to 7.
● If the cause of at least one message in "Current message case" is rectified and
acknowledged, the message buffer is reorganized accordingly. Messages that have not
been rectified remain in "Current message case".
● If "Current message case" contains eight messages and a new message is output, the
message in the parameters in index 7 is overwritten with the new message.
● r9744 is incremented each time the message buffer changes.
● A message value (r9749, r9753) can be output for a message. The message value is
used to diagnose the message more accurately (refer to the message description for
more details).

Deleting the message buffer:

The message buffer can be deleted as follows: p9752 = 0.
Parameter p9752 (SI message cases, counter) is also reset to 0 during POWER ON.

8.5.12 Safe actual value acquisition

Supported encoder systems

Safety functions used to monitor movements (e.g. SS2, SOS, SLS and SSM) require safe
actual value aquisition.
For safe speed/position sensing for SINAMICS S110, only a single-encoder system may be
used.

Single-encoder system
Encoders within single-encoder systems are used to generate the failsafe actual values of
the drive. This motor encoder must be appropriately qualified (see encoder types). The
safety-relevant actual values are generated either directly in the encoder or in the Sensor
Module and are transferred to the Control Unit by way of failsafe communication via DRIVE-
CLiQ.
For motors without a DRIVE-CLiQ interface, the connection is established by means of
additional Sensor Modules (SMC or SME).

NOTICE
When specifying the standstill tolerance window, observe that failsafe position monitoring
within a single-encoder system only works at a rough resolution with 4 pulses per
revolution.

Encoder types for single-encoder system

Incremental encoders or absolute encoders can be used for safe detection of the position
values on a drive.
Safe actual value acquisition relies on redundant evaluation of the incremental channels A/B
that supply sin/cos signals of 1 Vpp.
In single-encoder systems, encoders with photoelectric sampling only are permitted for safe
actual value acquisition. These optical encoders must supply sin/cos signals of 1 Vpp on the
incremental channels A/B.
The absolute position values can be transferred via the serial EnDat interface or an SSI
interface to the controller.

Note
Basic absolute encoders (e.g. ECI, EQI) that offer an EnDat interface with additional sin/cos
tracks, but operate according to an inductive measuring principle internally, are not permitted
for single-encoder systems.

Two read parameters are available for safe motion monitoring:

r9730: SI Motion maximum velocity
Displays the maximum velocity (load side) permissible due to the acquisition of actual values
for safe motion monitoring functions. The maximum velocity for actual value acquisition
depends on the actual value update clock cycle (p9311/p9511). Parameter p9311/p9511 can
be used to set the clock cycle of actual value acquisition for safe motion monitoring.
A slower clock cycle reduces the maximum permissible velocity, but also reduces the load
on the Control Unit for safe actual value acquisition.
The maximum permissible velocity which, if overshot, can trigger faults in safe actual value

8.5.13 Forced dormant error detection

Forced dormant error detection and function test through test stop
The functions and switch-off signal paths must be tested at least once within a defined
period to establish whether they are working properly in order to meet the requirements of
EN ISO 13849-1:2006 and IEC 61508 in terms of timely error detection.
The maximum permissible interval for forced dormant error detection with the Basic and
Extended Functions is 9000 hours or once a year.
This functionality must be implemented by means of test stop triggering either in cyclic
manual mode or by the automated process.
The test stop cycle is monitored. On expiration of the programmed timer, the alarm A01697:
"SI Motion: Test of motion monitoring required" is generated and a status bit is set which can
be transferred to an output or to a PZD bit via BICO. This alarm does not affect machine
operation.
The test stop must be initiated application-specific and be executed at a time which suits
application requirements. This functionality is implemented by means of a single-channel
parameter p9705 which can be wired via BICO either to an input terminal on the drive unit
(CU), or to an IO-PZD in the drive telegram.
● p9559 SI Motion forced dormant error detection timer (CPU 1)
● p9705 BI: SI Motion Test stop signal source
● r9723.0 CO/BO: SI Motion PROFIsafe diagnostics signals, dynamic response required
A test stop does not require POWER ON. The acknowledgment is set by canceling the test
stop request.
When the appropriate safety devices are implemented (e.g. protective doors), it can be
assumed that running machinery will not pose any risk to personnel. For this reason, only an
alarm is output to inform the user that a forced dormant error detection run is due and to
request that this be carried out at the next available opportunity.
Examples of when to carry out forced dormant error detection:
● When the drives are at a standstill after the system has been switched on.
● Before the protective door is opened.
● At defined intervals (e.g. every 8 hours).
● In automatic mode (time and event dependent)

Note
STO is triggered when a test stop is carried out for the Safety functions. The axis must
not be in operation.
STO must not be active before the test stop is selected.
When blocksize Power Modules are used, the test stop must be triggered under
controlled standstill conditions (speed setpoint setting 0) (OFF2 must not be active).

8.5 Safety Integrated Extended Functions

F-DI/F-DO forced dormant error detection

For forced dormant error detection of the F-DIs, the level of the F-DIs must be inverted, e.g.
by activating the appropriate switch or triggering the appropriate function in the connected
safety control. The correct reaction to the level change on the F-DIs must be observed by the
person carrying out the operation.
If the F-DO is used, it must undergo forced dormant error detection by triggering the
appropriate functions in the drive and the resulting level changes on the F-DO.
The correct function of the F-DO must be checked by whoever carries out forced dormant
error detection. The required format of the check is determined by the F-DO interconnection.
● F-DO at an F-DI of a safety switching device
(as illustrated in the section titled "Application examples/Input/output interconnections for
a safety switching device with CU305)
⇒ In the case of dormant error detection for the F-DO, its two output drivers are checked
by the F-DI of the connected safety switching device to ensure that they are functioning
correctly.
● F-DO at two contactors with positively-driven auxiliary contacts
(see the section titled Application examples/Interconnection of F-DO with redundant
contactors)
⇒ The feedback contacts of both contactors have to be monitored by a controller or
another monitoring unit to ensure that they both close when the F-DO is switched off (see
Application examples).
● When connecting other loads, remember that the correct function of the two output
drivers has to be monitored separately where forced dormant error detection is
concerned.
Please refer to the chapter titled "Commissioning safety terminals with
STARTER/SCOUT → Test stop" for more information on performing test stops.

8.6 Controlling the safety functions

8.6.1 Overview of F-DI/F-DOs and of their structure

The failsafe input and output terminals (F-DI and F-DO) act as an interface between the
internal Safety Integrated functionality and the process.
A dual channel signal applied to an F-DI (Failsafe Digital Input, safety-oriented digital input =
safe input terminal pair) controls the active monitoring of the activation/deactivation of safety
functions. This function also depends on the status of sensors (e.g. switches).
An F-DO (Failsafe Digital Output, safety-oriented digital output = safe output terminal pair)
delivers a dual channel signal representing feedback from the safety functions. It is also
suitable for the failsafe control of actuators (e.g. line contactor). See also diagram "Internal
connection of F-DI / F-DO of the CU305".

Dual-channel processing of I/O signals

A dual-channel structure is realized for data input/output and for processing failsafe I/O
signals. All requests and feedback signals for failsafe functions should be entered or tapped
using both channels.

The following options are available for controlling Safety Integrated functions:
● Control via safe input terminals on the Control Unit
● Control by way of PROFIsafe
The Basic Functions (STO, SBC, SS1 time controlled) can be controlled simultaneously
using a safe input terminal pair (F-DI0) and via PROFIsafe. For the Extended Functions,
control is only available either via the safe input terminal pairs or via PROFIsafe.

NOTICE
Control via PROFIsafe or TM54F is permitted for each Control Unit. Mixed operation is not
permitted.

Features
● Only for the STO, SS1 (time-controlled), and SBC functions
● Dual-channel structure via two input terminals as a safe input terminal pair
● Input filter for test signals with a dark period < 1 ms

Overview of the safety function terminals for SINAMICS S110

The digital input terminals DI16 and DI17 are defined as F-DI0 for the control of the Basic
Functions, if these are enabled (see diagram "Internal connection of DI/DO of the CU305
with safety function"). Both terminals are processed securely by different signal evaluators in
two channels. Both terminals must be operated simultaneously, otherwise a fault will be
issued.

Simultaneity and tolerance time of the two monitoring channels

The "Safe Torque Off" function must be selected/deselected simultaneously in both
monitoring channels using the input terminals and is only effective for the associated drive.
1 signal: Deselecting the function
0 signal: Selecting the function
"Simultaneously" means:
The changeover must be complete in both monitoring channels within the parameterized
tolerance time.
● p9650 SI SGE changeover tolerance time (CPU 1)
● p9850 SI SGE changeover tolerance time (CPU 2)
If the "Safe Torque Off" function is not selected/deselected within the tolerance time, this is
detected by the crosswise comparison and fault F01611 or F30611 (STOP F) is output. In
this case, the pulses have already been canceled as a result of the selection of "Safe Torque
Off" on one channel.

8.6.3 Control of the Safety Integrated Extended Functions using safe input terminals

General information
Control Unit CU305 has 6 digital inputs, which can be used as 3 safe input terminal pairs
(F-DI) for controlling the Extended Functions.
Furthermore, a single digital output on the CU305 can be extended as a safe output terminal
pair (F-DO) and used for the Extended Functions.
● F-DI 0 = DI16/DI17
● F-DI 1 = DI18/DI19
● F-DI 2 = DI20/DI21
● F-DO 0 = DO16+/DO16-
The signal states of the two digital inputs of the F-DI are frozen at logical 0 (safety function
selected) when different signal states are present within a failsafe F-DI until a safe
acknowledgment has been carried out by means of an F-DI via parameter p10006 (SI
acknowledgement internal event input terminal).
The monitoring time (p10002) for the discrepancy of the two digital inputs of an F-DI may
have to be increased so that switching operations do not trigger an undesired response,
thereby necessitating a safe acknowledgment. The signal states at the two related digital
inputs (F-DI) will need to have the same state within this monitoring time or fault message
C01770/C30770 will be triggered. This requires safe acknowledgment.

8.6 Controlling the safety functions

Description
Failsafe digital inputs (F-DI) consist of two digital inputs. The cathode of the optocoupler is
routed to the second digital input in order to allow the connection of an M-switching F-DO
output (the anode must be wired to 24 V DC).
Parameter p10140 is used to determine whether an F-DI is operated as NC/NC or NC/NO
contact. The status of each DI can be read at parameter r0722. The same bits of both drive
objects are logically linked by AND operation and return the status of the relevant F-DI.
Explanation of terms:
NC contact / NC contact: To select the safety function, a "zero level" must be present on
both inputs.
NC contact / NO contact: To select the safety function, a "zero level" at input 1 and a "1
level" at input 2 must be present.

The signal states at the two associated digital inputs (F-DI) must assume the same status
configured in p10140 within the monitoring time set in p10002.

F-DI features
● Failsafe configuration with two digital inputs per F-DI
● Input filter for test signals with an adjustable gating time (p9651/p9851)
● Configurable connection of NC/NC or NC/NO contacts by means of parameter p10140
● Status parameter r0722
● Adjustable time window for monitoring discrepancy at both digital inputs by means of
parameter p10002 for all F-DIs
● 2nd digital input with additional tap of the optocoupler cathode for connecting an
M-switching output of a failsafe controller.

WARNING
In contrast to mechanical switching contacts (e.g. EMERGENCY STOP switches),
leakage currents can still flow on semiconductor switches such as those usually used at
digital outputs even when they have been switched off. This can lead to false switching
states if digital inputs are not connected correctly.
The conditions for digital inputs/outputs specified in the relevant manufacturer
documentation must be observed.

WARNING
In accordance with IEC 61131 Part 2, Chapter 5.2 (2008), only outputs that have a
maximum residual current of 0.5 mA when "OFF" can be used to connect CU305 digital
inputs with digital semiconductor outputs.

The inclusion of additional load resistors makes it possible to use digital outputs with larger
residual currents to connect CU305 inputs.

Description
The failsafe digital output (F-DO) consists of two digital outputs. At the first digital output
DO16+ the 24 V potential connected to the terminal 24V1 is switched, and at the second
terminal the ground potential connected to terminal M1 is switched (see diagram below

8.6.5 Control by way of PROFIsafe

Safety Integrated functions

Safety Integrated functions can also be controlled via PROFIsafe, as opposed to control via
terminals or TM54F. PROFIsafe telegram 30 is used for communication via PROFIBUS.
The structure of the associated control and status words is described in more detail later in
this document (see the "Description of telegram 30" chapter).
SINAMICS Safety Integrated functions make a distinction between Safety Integrated Basic
Functions (STO/SS1/SBC) and Safety Integrated Extended Functions (Basic Functions plus
SS1, SS2, SLS, SOS, SSM).

Safety Integrated Basic Functions

The following options are available for controlling Safety Integrated Basic Functions:
● Terminals of the Control Unit and Power Modules (STO/SS1/SBC)
● PROFIsafe (telegram 30) via PROFIBUS
● PROFIsafe and terminals on the Control Unit and Power Modules

8.6.5.1 Setting up PROFIsafe communication

SINAMICS devices require a PROFIBUS interface for PROFIsafe communication.
Every drive with PROFIsafe configured in the drive unit is a PROFIsafe slave (F slave) with
failsafe communication to the F host via PROFIBUS and is assigned its own PROFIsafe
telegram.
In so doing, a PROFIsafe safety channel, a so-called safety-slot is created using the HW
Config tool from SIMATIC Manager Step 7. It is then possible to also control the Basic
Functions using PROFIsafe telegram 30. The structure of the associated control and status
words is described in more detail later in this document (see the "PROFIsafe STW" and
"PROFIsafe ZSW" tables). The PROFIsafe telegram 30 is placed in front of the standard
telegram for communication (e.g. telegram 2).

Note
Licensing for Safety Integrated Basic Functions via PROFIsafe
No license is required to use Safety Integrated Basic Functions. This also applies to control
via PROFIsafe.

Enabling PROFIsafe
The Basic Functions are enabled via PROFIsafe using bit 3 of parameters p9601 and p9801:
p9601.3 = p9801.3 = 1
All parameters involved in PROFIsafe communication are password protected against
undesirable changes and secured using a checksum. The telegrams are configured using a
configuration tool (e.g. HW Config + F-Configuration Pack or SCOUT) on the F host.

Safety Integrated Basic Functions via PROFIsafe and terminals

Control of the Basic Functions via terminals on the Control Unit and the Power Module
(parameters p9601.0 = p9801.0 = 1) may also be enabled. This means the STO and SS1
(time controlled) functions can be selected in parallel via both PROFIsafe telegram 30 and
the on-board terminals of the Control Unit and Power Module.

1st channel: Control Unit Terminals PROFIsafe telegram 30

2nd channel: Power Module Terminals PROFIsafe telegram 30
STO takes priority over SS1, i.e. STO is executed if SS1 and STO are triggered at the same
time.

General information
The Safety firmware on the CU305 Control Unit may have a different version number to the
overall firmware version.
The parameters listed below can be used to read the version IDs from the relevant hardware
components.
Read the overall firmware version via:
● r0018 Control Unit firmware version

The following firmware data can be read for the Basic Functions:
● r9770 SI version, drive-autonomous safety functions (Control Unit)

The following firmware data can be read for the Extended Functions:
● r9590 SI Motion Version safe movement monitoring (Control Unit)
● r9890 SI version (Sensor Module)

Basic Functions and Extended Functions

Basic or Extended Functions that have been enabled are checked to determine whether the
parameter for the automatic firmware update is set (p7826 = 1). This means the firmware
version of the connected Sensor Module (if any) or the connected motor with DRIVE-CLiQ
connection is compared to the firmware version on the Control Unit during booting, and
updated if necessary.
During the acceptance test for Safety Integrated Basic Functions, the Safety firmware
versions of the Motor Modules must be read, logged, and checked against the list below.
During the acceptance test for the Safety Integrated Extended Functions, the Sfety firmware
versions of the Control Unit and the Sensor Modules or motor with DRIVE-CLiQ connection
required for the safety functions are to be read, logged, and checked against the list below.
When Extended Functions are used, the firmware requirements for Basic Functions must
also be fulfilled at all times.
The list of permissible Sfety firmware version combinations which must be used as a
reference during the test, can be found under "Product Support" at the following address:
http://support.automation.siemens.com/WW/view/en/28554461

The password "0" is set by default.

NOTICE
For safety reasons, you can only set the safety-related parameters of the Control Unit
offline with the STARTER commissioning tool V4.1.5 and higher (or SCOUT). In order to
set safety-related parameters for the Power Module, establish an online connection to
SINAMICS S110 and use the "Copy parameters" button to copy the parameters to the

On exiting commissioning mode (p0010 = 0), most of the changed parameters become
active immediately. For some parameters, however, a POWER ON is required: If this is the
case, a STARTER message will inform you about this.
When performing an acceptance test, a POWER ON is always required.

Prerequisites for commissioning the safety functions (Basic Functions)

1. Commissioning of the drive must be complete.
2. Non-safe pulse suppression must be present (e.g. via
OFF1 = "0" or OFF2 = "0")
If the motor holding brake is connected and parameterized, the holding brake is applied.
3. The terminals for "Safe Torque Off" must be wired.
4. For operation with SBC, the following applies:
A motor with motor holding brake must be connected to the appropriate terminal of the
Power Module.

8.7.2.3 Standard commissioning of Safety Integrated functions

Standard commissioning of the safety functions

1. A commissioned project that has been uploaded to STARTER can be transferred to
another drive unit still keeping the existing Safety parameterization.
2. If the source and target devices have different software versions, the reference
checksums (p9799, p9899) may have to be adapted. This is indicated by the faults
F01650 (fault value: 1000) and F30650 (fault value: 1000).
3. Once the project has been downloaded to the target device, an acceptance must be
carried out. This is indicated by fault F01650 (fault value: 2004). Additional information on
the acceptance test is provided in the Function Manual "Safety Integrated" in Chapter
"Acceptance test and acceptance report".

8.7.2.4 Setting the sampling times

Terminology
The software functions installed in the system are executed cyclically at different sampling
times.
Safety functions are executed within the monitoring clock cycle (p9300/p9500).
Communication on PROFIBUS is handled cyclically by means of the communication clock
cycle.
During the PROFIsafe scan cycle, the PROFIsafe telegrams issued by the master are
evaluated.

Rules for setting the sampling times

● The monitoring clock cycle (p9300/p9500) can be set between 500 μs to 25 ms.
However, the calculation time required for the Extended Functions in the Control Unit
depends on the monitoring clock cycle, that is, shorter clock cycles extend the calculation
time. The availability of a specific monitoring clock cycle therefore depends on calculation
time resources of the Control Unit.
Calculation time resources on the Control Unit are affected primarily by the enabled
Extended Functions and the selected technological functions.
● The monitoring cycle (p9300/p9500) must be an integer multiple of the actual value
update clock cycle (p9311/p9511).
● If Extended Safety Functions are being used, p9311/p9511 must be set ≥ 4 * current
controller cycle and ≥ 2 ms.

Overview of important parameters (see SINAMICS S110 List Manual)

● p9300 SI Motion monitoring clock cycle (Power Module)
● p9311 SI Motion clock cycle actual value sensing (Power Module)
● p9500 SI Motion monitoring clock cycle (Control Unit)
● p9511 SI Motion clock cycle actual value sensing (Control Unit)

8.7.3.3 Configuration of the safety terminals

Configuration screen of the terminals for Safety Integrated

Figure 8-21 Configuring safety terminals

Functions of this screen:

● F-DI discrepancy time (p10002)
The signal states at the two terminals of an F-DI are monitored in order to determine
whether these have assumed the same logical state within the discrepancy time.
● F-DI input filter (p10017, p10117)
Parameterization of the debounce time for the F-DIs. A rounded debounce time (to a full
ms) is accepted. The debounce time specifies the maximum time an interference pulse
can be present at F-DIs before being interpreted as a safety-related signal.
● F-DI selection (p10006)
The Extended Functions enter a safety alarm in a special alarm buffer upon the detection
of internal errors or violation of limits. This alarm must be acknowledged safely. You can
assign an F-DI terminal pair for safe acknowledgment.
● Signal source forced dormant error detection (p10007)
Selection of an input terminal for the start of the test stop: The test stop is initiated by a
0/1 signal from the input terminal and can only be performed when the drive is not in
commissioning mode.
● F-DO dynamization test cycle (p10003)
Failsafe I/O must be tested at defined intervals in order to validate their failsafe state (test
stop or forced dormant error detection). Control Unit 305 has a function block for this
purpose. When selected via a BICO source, it executes this forced dormant error
detection (e.g. switching the sensor power supply). Each selection triggers a timer in
order to monitor the test cycle. An alarm is set on expiration of the monitored time.

8.7.3.4 Test stop

Testing failsafe I/O

Failsafe I/O must be tested at defined intervals in order to validate their failsafe state (test
stop or forced dormant error detection). CU305 has a function block for this purpose. When
selected via a BICO source, it executes this forced dormant error detection (e.g. switching
the L1+ and L2+ sensor power supply). Each selection triggers a timer in order to monitor
the test cycle. An alarm is set on expiration of the monitored time.
Three test stop modes are available for SINAMICS S110. After a certain time has elapsed,
an alarm informs the user that a test stop needs to be performed for the F-DI/DO. The
various test stop modes and the required test sequences are described below.

Preparations before performing test stops

Before carrying out parameterization and configuration work, the F-DO circuit used for the
test stop mode selected needs to be defined and parameterized accordingly.
After the period specified by the timer for the forced dormant error detection interval has
elapsed, an alarm informs the user that a test stop needs to be performed for the F-DI/DO.
The test stop should be initiated by, for example, a control signal or a switch via a BICO-
interconnectable signal.
The alarm only disappears again after the test stop has been performed.

This form of monitoring can be used to demonstrate whether the F-DO output transistors can
be switched (off), even if the actuator itself does not provide any feedback.

With circuits which have two relays with positively-driven feedback contacts (fault exclusion)
or an actuator with a separate feedback message (e.g. a solenoid valve), this sequence can

8.7.4 PROFIsafe configuration with STARTER

PROFIsafe commissioning with STARTER

The Safety Integrated Basic Functions can be commissioned using STARTER in three ways.
1. STO/SS1/SBC only via terminals
2. STO/SS1/SBC only via PROFIsafe
3. STO/SS1/SBC via PROFIsafe and terminals simultaneously
There follows a brief overview of the STARTER functionality which enables Safety Integrated
Basic Functions to be used by means of terminals, PROFIsafe, or a combination of the two.

Safety slot
In order to use Safety Integrated functions via PROFIBUS or PROFINET, a safety slot must
first be created using SIMATIC Manager Step 7 and HW Config. The procedure to do this
was described in the previous chapters.

Expert list
The Safety Integrated Basic Functions can be individually and manually set using the Expert
list – but the settings using the STARTER screen forms are more user friendly and you are
less prone to making mistakes.

Calling Safety Integrated in STARTER

● The STARTER screen form for "Safety Integrated" is called under Drives/Functions with a
double-click and can look like this (tree-type view depends on the specific project):
● To use the full functionality of STARTER screens, there must be an online connection
between the drives, the control, and STARTER.
● Select the type of control for Safety Integrated from the control list.
● Depending on the selection, different setting screens open for:
– STO/SBC/SS1 via terminals
– STO/SBC/SS1 via PROFIsafe
– STO/SBC/SS1 via PROFIsafe and terminal

Activating PROFIsafe via the expert list

In order to activate Safety Integrated Basic Functions via PROFIsafe, bit 3 of p9601 and
p9801 in the expert list must be set to "1" and bit 2 to "0". Bit 0 must be set to either "1" or
"0", depending on whether or not control via terminals is to be enabled in parallel to control
via PROFIsafe.

Saving and copying Basic Functions

After setting the specific parameters for Safety Integrated functions (e.g. the PROFIsafe
address), these must be copied from the CU to the Power Module using the "Copy
parameters" button and activated using the "Activate settings" button.

Acceptance test
An acceptance test needs to be carried out once configuration and commissioning are
complete (see relevant chapter).

Note
If F parameters of the SINAMICS drive are changed in HW Config, the global signature of
the safety program in the SIMATIC F-CPU changes. This means the global signature can be
used to identify whether safety-related settings have changed in the F-CPU (F parameters of
the SINAMICS slave). However, this global signature does not include the safety-relevant
drive parameters so that their change cannot be checked in this way.

F_Dest_Add determines the PROFIsafe destination address of the drive object.
Any value within the range is allowed, however, it must be entered once again in the safety
configuration of the drive in the SINAMICS drive unit. The F_Dest_Add value must be set in
p9610 (Control Unit) and in p9810 (Power Module). You can handle these settings quite
comfortably using the PROFIsafe STARTER screen (see the picture below). The PROFIsafe
target address must be entered in hexadecimal format.

Figure 8-31 PROFIsafe STARTER configuration

F_WD_Time: 10- 65535

A valid current safety message frame must be received from the F-CPU within the
monitoring time. The drive will otherwise go into safe state.
Select a monitoring time of sufficient length to let the communication functions tolerate
telegram delays, however, make allowances for appropriate short fault reaction times (e.g. to
interruption of communications).
For additional information on failsafe parameters, refer to the online help of the "PROFIsafe

Replacing components for Safety Integrated

WARNING
Refer to the notes regarding changes to or replacement of software components in the
"Safety instructions" chapter!

1. The faulty component was replaced in accordance with safety regulations.

2. Make sure that everybody has cleared the danger zone and then power up the machine.
3. Error F30711 is output with fault value 1031 (data transfer error after replacement of a
Sensor Module).
4. With STARTER:
– Click "Acknowledge hardware replacement" in the start screen of Safety functions.
5. Without STARTER:
– Start the copying function for Node Identifier (p9700 = 1D hex)
– Confirm the hardware CRC on the drive object (p9701 = EC hex)
6. Back up all parameters.
7. Perform a POWER ON at all components.
8. Faults F01650/F30650 (acceptance test required; see "Acceptance test and acceptance
report") are output.
9. Carry out an acceptance test and draw up an acceptance report as described in the
"Acceptance test and acceptance report" chapter and the table titled "Effect of the
acceptance test on specific measures".

WARNING
Before anyone is allowed to enter the danger zone again and before operation is resumed,
select the STO function once and briefly move the drives affected by the component
replacement in both directions (+/-) with the safety monitoring function activated (SLS, if
parameterized) in order to verify proper functionality.

8.7.7 Information pertaining to series commissioning

A commissioned project that has been uploaded to STARTER can be transferred to another
drive unit keeping the existing Safety parameterization.
1. Load the STARTER project to the drive unit.
2. Make sure that everybody has cleared the danger zone and then power up the machine.
3. The alarms F01650/F30650 (acceptance test required) are output.
These fault alarms can be acknowledged because a full acceptance test is not required if
no changes were made to safety function parameters.
4. With STARTER/SCOUT:
– Click Acknowledge hardware replacement on the start screen for the Safety functions.
5. If you are using SINAMICS with a BOP or SIMOTION with an HMI, you will need to carry
out the following steps:
– Start the copying function for the Node Identifier (p9700 = 1D hex).
– Confirm the hardware CRC on the drive object (p9701 = EC hex).
6. Save all parameters to the non-volatile memory.
7. Perform a POWER ON at all components.
8. Faults F01650/F30650 are output (acceptance test required; see the "Acceptance test
and acceptance report" chapter and the table titled "Effect of the acceptance test on
specific measures").

WARNING
Before anyone is allowed to enter the danger zone again and before operation is resumed,
select the STO function once and briefly move the drives affected by the component
replacement in both directions (+/-) with the safety monitoring function activated (SLS, if
parameterized) in order to verify proper functionality.

Safety alarm for standard commissioning with Safety Integrated Extended Functions
If third-party motors with absolute encoders are being used, a situation may arise where a
safety alarm prevents commissioning.
One possible reason may be that the serial number for the absolute encoder saved in the
memory is different to the one in the Control Unit to be commissioned. The safety alarm can
only be acknowledged once the serial number for the absolute encoder has been corrected
manually (e.g. with STARTER). For information on how to do this, see the "Information on
replacing components" chapter. You can carry on with commissioning work once you have
done this.

Interconnecting F-DI with plus-minus switching output on safety device

WARNING
In contrast to mechanical switching contacts (e.g. EMERGENCY STOP switches), leakage
currents can still flow with semiconductor switches, such as those usually used at digital
outputs, even when they have been switched off. This can lead to false switching states if
digital inputs are not connected correctly.
The conditions for digital inputs/outputs specified in the relevant manufacturer
documentation must be observed.

Note
F-DO test pulses
Some safety blocks have F-DOs which emit test pulses for self-test purposes and in order to
check the transmission path. These test pulses may trigger false alarms requiring a safe
acknowledgment. To avoid these false alarms, discrepancy time p10002 should be set at a
sufficiently high level to prevent any interference with the safety function itself. Our
experience has shown a setting of approx. 150 ms to be adequate, but it is essential to take
into account the description of functions for the F-DO test pulses of the safety control.

WARNING
In accordance with IEC 61131 Part 2, Chapter 5.2 (2008), only outputs that have a
maximum residual current of 0.5 mA when "OFF" can be used to connect CU305 digital
inputs with digital semiconductor outputs.

Debouncing
Parameter p10017 (SI digital inputs debounce time) can be used to filter out test signals from
controls. This avoids faults generated by misinterpretations.
F-DI = safety-related dual-channel digital input
F-DO = safety-related dual-channel digital output
If the digital outputs from another device (e.g. F-DOs on a safety PLC) with a residual current
greater than 0.5 mA when "OFF" are connected to the CU305 F-DIs, F-DI load resistors
should be connected in the relevant channel.
The maximum permissible voltage for a CU305 F-DI when "OFF" is 5 V (in accordance with
IEC 61131-2, 2008).
The following two figures show exactly how the protective circuits for F-DIs with additional
load resistors are wired.

Dimensioning of load resistors - example 1:

According to manufacturer documentation, the leakage current of an F-DO on a safety PLC
is 1 mA for the P and F channel; in other words, it is 0.5 mA higher than is permissible for the
F-DI.
The necessary load resistance is therefore R = 5 V/0.5 mA = 10 kΩ.
At maximum supply voltage, the power loss for this resistor is:
P = (28.8 V)²/R = 83 mW. The resistor is to be permanently dimensioned for this power loss.

Dimensioning of load resistors - example 2:

If further conditions for the digital output (e.g. a minimum load or a maximum load
resistance) are specified in the manufacturer documentation, these must also be taken into
account.
For example, a load between 12 Ω and 1 kΩ is specified for the SIMATIC ET200S 4 F-DO
I/O module (6ES7138-4FB02-0AB0).
Therefore, two additional 1 kΩ load resistors and a continuous load capacity of at least P =
(28.8 V)²/R = 830 mW are required to connect an F-DO of this kind to a CU305 F-DI.
If a controlled 24 V power supply is used (e.g. SITOP), a resistor with a significantly lower
power loss is sufficient.

Note
Open-circuit detection for pull-up resistors
If the pull-up resistor has a resistance greater than 1 kΩ, open-circuit detection is no longer
reliable and has to be switched off.

8.9 Acceptance test and acceptance report

8.9 Acceptance test and acceptance report

Requirements regarding acceptance tests are derived from the EC Machinery Directive and
ISO 13849-1. IEC 22G WG 10 is currently working on a "Functional safety" standard which
includes a detailed description of acceptance test requirements. The machine manufacturer
(OEM) is committed accordingly
● to carry out an acceptance test for safety-related functions and machine parts
● to issue an "Acceptance certificate" which describes the test results.
The acceptance test for systems with Safety Integrated Extended Functions (SI functions) is
focused on validating the functionality of Safety Integrated monitoring and stop functions
implemented in the drive system. The test objective is to verify proper implementation of the
defined safety functions and of test mechanisms (forced dormant error detection measures)
and to examine the response of specific monitoring functions to the explicit input of values
outside tolerance limits. This has to be conducted for all drive-specific Safety Integrated
motion monitoring procedures.

WARNING
A new acceptance test must be carried out if any changes were made to SI function
parameters and must be logged in the acceptance report.

Note
The acceptance test is designed to ensure that the safety functions are correctly
parameterized. The measured values (e.g. distance, time) and the system behavior identified
(e.g. initiation of a specific stop) can be used for checking the plausibility of the configured
safety functions. The objective of an acceptance test is to identify potential configuration
errors or to record the valid configuration. The measured values are typical but no worst
case values. They represent the behavior of the machine at the time of measurement. These
measurements cannot be used, for example, to derive maximum ramp-down values.

8.9 Acceptance test and acceptance report

Authorized person, acceptance report

The test of each SI function must be carried out by an authorized person and logged in the
acceptance report. The report must be signed by the person who carried out the acceptance
test. The acceptance report must be kept in the logbook of the relevant machine. Access
rights to SI parameters must be protected by password and be recorded accordingly in the
acceptance report. In this context this is a person who is authorized by the machine
manufacturer and who has adequate professional training and knowledge of the safety
functions in order to conduct the acceptance test in a proficient manner.

Note
• Observe the information in the chapter "Procedures for initial commissioning".
• The acceptance report presented below is both an example and recommendation.
• An acceptance report template in electronic format is available at your local sales office.

Necessity of an acceptance test

A complete acceptance test (as described in this chapter) is required after initial
commissioning of Safety Integrated functionality on a machine. An acceptance test, possible
with reduced scope, is always required after safety-related functions were extended, after
the transfer of commissioned objects to other series machines, after changes were made to
the hardware and after software upgrades. A summary of conditions which determine the
necessary test scope or proposals in this context is provided below.
In order to define a partial acceptance test, it is necessary in the first instance to specify the
acceptance test objects, and in the second instance to define logical groups which represent
the elements of the acceptance test. The acceptance test must be carried out separately for
each individual drive (as far as the machine allows).

Prerequisites for the acceptance test

● The machine is properly wired.
● All safety equipment such as protective door monitoring devices, light barriers or
emergency-off switches are connected and ready for operation.
● Commissioning of the open-loop and closed-loop control should be concluded, as the
ramp-down path may otherwise change as a result of changed dynamic response of the
drive controller, for example. These include, for example:
– Configuration of the setpoint channel
– Position control in the higher-level controller
– Drive control.

8.9 Acceptance test and acceptance report

Information about the acceptance tests

Note
As far as possible, the acceptance tests are to be carried out at the maximum possible
machine speed and acceleration rates to determine the maximum braking distances and
stop times that can be expected.

Information on acceptance test mode

Acceptance test mode can be activated for a definable period (p9358/p9558) by setting the
appropriate parameters (p9370/p9570). It tolerates specific limit violations during the
acceptance test. For example, speed setpoint limits no longer apply in acceptance test
mode. To prevent this state from being allowed to continue due to an oversight, acceptance
test mode terminates automatically after the time set in p9358/p9558 has elapsed.
It is only worth activating acceptance test mode during the acceptance tests for functions
SOS and SLS. It has no effect on other functions.
Normally, SOS can be selected directly or via an SS2. If you want to be able to trigger a
violation of standstill limits in the SS2 state as well when acceptance test mode is active,
acceptance test mode deactivates the SS2 brake ramp and enables the motor to move.
When an SOS violation is acknowledged in active acceptance test mode, the current position
is adopted as the new standstill position to prevent the immediate detection of another SOS
violation.

WARNING
If a speed setpoint other than zero is present, the active stop function SS2 is set, and the
motor is at a standstill (active SOS), the axis starts to move as soon as the acceptance test
is activated.

8.9.1 Safety logbook

Description
The "Safety Logbook" function is used to detect changes to Safety parameters that affect the
associated CRC sums. CRCs are only generated when p9601/p9801 (SI enable, functions
integrated in the drive, CU/Motor Module) is > 0.
Data changes are detected when the CRCs of the SI parameters change. Each SI parameter
change that is to become active requires the reference CRC to be changed so that the drive
can be operated without SI fault messages. In addition to functional safety changes, safety
changes as a result of hardware being replaced can be detected when the CRC has
changed.
The following changes are recorded by the safety logbook:
● Functional changes are recorded in the checksum r9781[0]:
– Functional CRCs of the motion monitoring functions (p9729[0]), axial (Extended
Functions).
– Functional CRCs of the basic safety functions integrated in the drive (p9799, SI
reference checksum SI parameters CU), axial.
– Enabling of functions integrated in the drive (p9601), axial (Basic and Extended
Functions).
● Hardware-dependent changes are recorded in the checksum r9781[1]:
– Hardware-dependent CRCs of the motion monitoring functions (p9729[2]), axial (ncSI,
Basic and Extended Functions)

Overview of important parameters (see SINAMICS S110 List Manual)

● r9781[0] SI checksum to check changes (Control Unit), functional
● r9781[1] SI checksum to check changes (Control Unit), hardware dependent
● r9782[0] SI time stamp to check changes (Control Unit), functional
● r9782[1] SI time stamp to check changes (Control Unit), hardware dependent
● r9728[0...2] SI Motion actual checksum, SI parameters
● r9729[0...2] SI Motion reference checksum, SI parameters

9.2.2 Application classes

Description
There are different application classes for PROFIdrive, depending on the scope and type of
the application processes. There are a total of 6 application classes in PROFIdrive, of which
4 are discussed here.

Application class 1 (standard drive)

In the most basic case, the drive is controlled via a speed setpoint by means of PROFIBUS.
In this case, speed control is fully handled in the drive controller. Typical application
examples are basic frequency converters. Pump and fan control.

9.2 Communication according to PROFIdrive

Application class 2 (standard drive with technology function)

The total process is subdivided into a number of small subprocesses and distributed among
the drives. This means that the automation functions no longer reside exclusively in the
central automation device but are also distributed in the drive controllers.
Of course, this distribution assumes that communication is possible in every direction, i.e.
also cross-communication between the technology functions of the individual drive
controllers. Specific applications include e.g. setpoint cascades, winders and speed
synchronization applications for continuous processes with a continuous web.

Application class 3 (positioning drive)

In addition to the drive control, the drive also includes a positioning control, so that the drive
operates as an autonomous basic positioning drive, while the higher-level technological
processes are executed on the controller. Positioning requests are transmitted to the drive
controller via PROFIBUS and launched. Positioning drives have a very wide range of
applications, e.g. the screwing and unscrewing of caps in a bottle filling plant or the
positioning of cutters on a film cutting machine.

Application class 4 (central motion control)

This application class defines a speed setpoint interface with execution of the speed control
on the drive and of the positioning control in the controller, such as is required for robotics
and machine tool applications with coordinated motions on multiple drives.
Motion control is primarily implemented by means of a central numerical controller (CNC).
The position control loop is closed via the bus. The synchronization of the position control
cycles in the control and in the closed-loop controllers in the drive requires a clock
synchronization of the kind provided by PROFIBUS DP.

Dynamic Servo Control (DSC)

The PFOFIdrive profile contains the "Dynamic Servo Control" control concept. This can be
used to significantly increase the dynamic stability of the position control loop in application
class 4 with simple means.
For this purpose, the deadtime that is typical for a speed setpoint interface is minimized by
an additional measure (see also chapter "Dynamic Servo Control").

9.2.3 Cyclic communication

Cyclic communication is used to exchange time-critical process data.

9.2.3.1 Telegrams and process data

General information
The selection of a telegram via p0922 determines which data on the drive unit side (Control
Unit) will be transferred.
From the perspective of the drive unit, the received process data comprises the receive
words and the process data to be sent the send words.
The receive and send words comprise the following elements:
● Receive words: Control words or setpoints
● Send words: Status words or actual values

What telegrams are available?

1. Standard telegrams
The standard telegrams are structured in accordance with the PROFIdrive Profile. The
internal process data links are set up automatically in accordance with the telegram
number setting.
The following standard telegrams can be set via p0922:
– 1 Speed setpoint, 16 bit
– 2 Speed setpoint, 32 bit
– 3 Speed setpoint, 32 bit with 1 position encoder
– 4 Speed setpoint, 32 bit with 2 position encoders
– 7 Positioning, telegram 7 (basic positioner)
– 9 Positioning, telegram 9 (basic positioner with direct input)
2. Manufacturer-specific telegrams
The manufacturer-specific telegrams are structured in accordance with internal company
specifications. The internal process data links are set up automatically in accordance with
the telegram number setting.
The following vendor-specific telegrams can be set via p0922:
– 102 Speed setpoint, 32 bit with 1 position encoder and torque reduction
– 103 Speed setpoint, 32 bit with 2 position encoders and torque reduction
– 110 Positioning, telegram 10 (basic positioner with MDI, override and XIST_A)
– 111 Positioning, telegram 11 (basic positioner in MDI mode)
– 390 Control Unit with digital inputs/outputs

1) Each PZD word can be assigned a word or a double word. Only one of the two interconnection
parameters r2050 or r2060 can have a value ≠ 0 for a PZD word.

Telegram interconnections
When you change p0922 = 999 (factory setting) to p0922 ≠ 999, the telegrams are
interconnected and blocked automatically.

Note
Telegram 111 is the exception: Here, PZD12 in the transmit telegram or PZD12 in the
receive telegram can be interconnected as required.

When you change p0922 ≠ 999 to p0922 = 999, the previous telegram interconnection is
retained and can be changed.

Note
If p0922 = 999, a telegram can be selected in p2079. A telegram interconnection is
automatically made and blocked. The telegram can also be extended.
This is an easy method of creating extended telegram interconnections on the basis of
existing telegrams.

The telegram structure

The parameter p0978 contains the sequence of DOs that use a cyclic PZD exchange. A zero
delimits the DOs that do not exchange any PZDs.
If the value 255 is written to p0978, the drive unit emulates an empty drive object that is
visible to the PROFIdrive Master. This permits cyclic communication of a PROFIdrive Master
● with unchanged configuration to drive units that have a different number of drive objects.
● with deactivated DOs without having to change the project.

Note
• The following must apply to ensure conformity with the PROFIdrive profile:
– Interconnect PZD receive word 1 as control word 1 (STW1).
– Interconnect PZD send word 1 as status word 1 (STW1).
Use WORD format for PZD1.
• One PZD = one word.
Only one of the interconnection parameters (p2051 or p2061) can have the value ≠ 0
for a PZD word.
• Physical word and double word values are inserted in the telegram as referenced
variables.
p200x are relevant as reference values (telegram contents = 4000 hex or
4000 0000 hex for double words if the input variable has a value of p200x).

Structure of the telegrams

You can find an overview of the structure of telegrams in function diagrams 2420, 2422, and
2423 in the SINAMICS S110 List Manual.
Depending on the drive object, only certain telegrams can be used:

Drive object Telegrams (p0922)

SERVO 1, 2, 3, 4, 102, 103, 999
SERVO (EPOS) 7, 9, 110, 111, 999
CU_S110 390, 391, 999
Depending on the drive object, the following maximum number of process data items can be
transmitted for user-defined telegram structures:

Drive object Max. number of PZD for sending / receiving

• SERVO Send 19, receive 16
• CU_S110 Send 15, receive 5

Interface Mode
Interface Mode is used for adjusting the assignment of the control and status words in line
with other drive systems and standardized interfaces.
The mode can be set as follows:

Value Interface Mode

p2038 = 0 SINAMICS (factory setting)
p2038 = 1 SIMODRIVE 611 universal

Procedure:
1. Set p0922 ≠ 999.
2. p2038 = set required interface mode.
If you set telegrams 102 and 103, Interface Mode is set by default (p2038 = 1) and cannot be
changed.
Interface Mode is also set by default with positioning telegrams (7, 9, 110, and 111) and
cannot be changed (p2038 = 0 set).
When a telegram that specifies the Interface Mode (e.g. p0922 = 102) is changed to a
different telegram (e.g. p0922 = 3), the setting in p2038 is retained.

This chapter describes the assignment and meaning of the process data in SINAMICS
interface mode (p2038 = 0).
The reference parameter is also specified for the relevant process data. The process data
are generally normalized in accordance with parameters p2000 to r2004.
The following scalings apply:
A temperature of 100°C = 100% and 0°C = 0%
An electrical angle of 90° = 100 % and 0° = 0%.

6 No motor overtemperature alarm 1 No motor overtemperature alarm BO: r2135.14
The temperature of the motor is within the
permissible range.
0 Alarm, motor overtemperature
The temperature of the motor is greater than the set
motor temperature threshold (p0604).
Note:
• When the motor temperature threshold is exceeded, only an alarm is output initially to warn you of this. The
alarm is canceled automatically when the temperature no longer exceeds the alarm threshold.
• If the overtemperature is present for longer than the value set via p0606, a fault is output to warn you of this.
• Motor temperature monitoring can be switched out via p0600 = 0.
Application:
The user can respond to this message by reducing the load, thereby preventing the motor from shutting down with
the "Motor temperature exceeded" fault after the set time has elapsed.

MTn_ZS_F and MTn_ZS_S

Display of the measuring time determined
The measuring time is specified as a 16-bit value with a resolution of 0.25 μs.

Features of the central probe

● The time stamps from probes in more than one drive can be transferred simultaneously in
a single telegram.
● The time in the controller and drive unit is synchronized via CU_STW1 and the
CU_ZSW1.
Note: The controller must support time synchronization!
● A higher-level controller can then use the time stamp to determine the actual position
value of more than one drive.
● The system outputs a message if the measuring time determination function in the probe
is already in use (see also p0488, p0489, and p0580).

Example: central probe

Assumptions for the example:
● Determination of the time stamp MT1_ZS_S by evaluating the rising edge of probe 1
● Determination of the time stamp MT2_ZS_S and MT2_ZS_F by evaluating the rising and
falling edge of probe 2
● Probe 1 on DI/DO 9 of the Control Unit (p0680[0] = 1)
● Probe 2 on DI/DO 10 of the Control Unit (p0680[1] = 2)
● Manufacturer-specific telegram p0922 = 391 is set.

9.2.3.6 Motion Control with PROFIdrive

Description
The "Motion Control with PROFIBUS" or "Motion Control with PROFINET" function can be
used to implement an isochronous drive link between a master and one or more slaves via
the PROFIBUS field bus or an isochronous drive link via PROFINET.

Note
The isochronous drive link is defined in the following documentation:
Reference: /P5/ PROFIdrive Profile Drive Technology

Properties
● No additional parameters need to be entered in addition to the bus configuration in order
to activate this function, the master and slave must only be preset for this function
(PROFIBUS).
● The master-side default setting is made via the hardware configuration, e.g. B. HWConfig
with SIMATIC S7. The slave-side default setting is made via the parameterization
telegram when the bus is ramping up.
● Fixed sampling times are used for all data communication.
● The Global Control (GC) clock information on PROFIBUS is transmitted before the
beginning of each cycle.
● The length of the clock cycle depends on the bus configuration. When the clock cycle is
selected, the bus configuration tool (e.g. HWConfig) supports:
– High number of drives per slave/drive unit → longer cycle
– Large number of slaves/drive units → longer cycle
● A sign-of-life counter is used to monitor user data transfer and clock pulse failures.

Overview of closed-loop control

● Sensing of the actual position value on the slave can be performed using:
– Indirect measuring system (motor encoder)
– Additional direct measuring system
● The encoder interface must be configured in the process data.
● The control loop is closed via the PROFIBUS.
● The position controller is located on the master.
● The current and speed control systems and actual value sensing (encoder interface) are
located on the slave.
● The position controller clock cycle is transmitted across the field bus to the slaves.
● The slaves synchronize their speed and/or current controller cycle with the position
controller cycle on the master.
● The speed setpoint is specified by the master.

9.2.4.1 General information about acyclic communication

Description
With acyclic communication, as opposed to cyclic communication, data transfer takes place
only when an explicit request is made (e.g. in order to read and write parameters).
The read data set/write data set services are available for acyclic communication.
The following options are available for reading and writing parameters:
● S7 protocol
This protocol uses the STARTER commissioning tool, for example, in online mode via
PROFIBUS.

9.2.4.3 Determining the drive object numbers

Further information about the drive system (e.g. drive object numbers) can be determined as
follows using parameters p0101 and r0102:
1. The value of parameter r0102 ("Number of drive objects") for drive object/axis 1 is read
via a read request.
Drive object 1 is the Control Unit (CU), which is a minimum requirement for each drive
system.
2. Depending on the result of the initial read request, further read requests for drive object 1
are used to read the indices for parameter p0101 ("Drive object numbers"), as specified
by parameter r0102.
Example:
If the number of drive objects is "5", the values for indices 0 to 4 for parameter p0101 are
read. Of course, the relevant indexes can also be read at once.

9.2.4.4 Example 1: read parameters

Requirements
1. The PROFIdrive controller has been commissioned and is fully operational.
2. PROFIdrive communication between the controller and the device is operational.
3. The controller can read and write data sets in conformance with PROFIdrive DPV1.

Task description
Following the occurrence of at least one fault (ZSW1.3 = "1") on drive 2 (also drive object
number 2), the active fault codes must be read from the fault buffer r0945[0] ... r0945[7].
The request is to be handled using a request and response data block.

Basic procedure
1. Create a request to read the parameters.
2. Invoke the request.
3. Evaluate the response.

9.3.1 General information about PROFIBUS

General information
PROFIBUS is an open international field bus standard for a wide range of production and
process automation applications.
The following standards ensure open, multi-vendor systems:
● International standard EN 50170
● International standard IEC 61158
PROFIBUS is optimized for high-speed, time-critical data communication at field level.

Note
PROFIBUS for drive technology is standardized and described in the following document:
Reference: /P5/ PROFIdrive Profile Drive Technology

CAUTION
Before synchronizing to the isochronous PROFIBUS, all of the pulses of the drive objects
must be inhibited - also for those drives that are not controlled via PROFIBUS.

CAUTION
No CAN cables must be connected to interface X126. If CAN cables are connected, the
CU305 and other CAN bus nodes could be seriously damaged.

Master and slave

● Master and slave properties

Table 9- 33 Master and slave properties

Properties Master Slave

As bus node Active Passive
Send messages Permitted without external Only possible on request by
request master
Receive messages Possible with no restrictions Only receive and acknowledge
permitted
● Master
Masters are categorized into the following classes:
– Master class 1 (DPMC1):
Central automation stations that exchange data with the slaves in cyclic and acyclic
mode. Communication between the masters is also possible.
Examples: SIMATIC S7, SIMOTION
– Master class 2 (DPMC2):
Devices for configuration, commissioning, operator control and monitoring during bus
operation. Devices that only exchange data with the slaves in acyclic mode.
Examples: Programming devices, human machine interfaces
● Slaves
With respect to PROFIBUS, the SINAMICS drive unit is a slave.

Bus access method

PROFIBUS uses the token passing method, i.e. the active stations (masters) are arranged in
a logical ring in which the authorization to send is received within a defined time frame.
Within this time frame, the master with authorization to send can communicate with other
masters or handle communication with the assigned slaves in a master/slave procedure.

PROFIBUS telegram for cyclic data transmission and acyclic services

Each drive unit that supports cyclic process data exchange uses a telegram to send and
receive all the process data. A separate telegram is sent in order to perform all the acyclic
services (read/write parameters) under a single PROFIBUS address. The acyclic data is
transmitted with a lower priority after cyclic data transmission.
The overall length of the telegram increases with the number of drive objects that are
involved in exchanging process data.

References: SINAMICS S110 Equipment Manual
● PROFIBUS diagnostic LED

Note
A teleservice adapter can be connected to the PROFIBUS interface (X126) for remote
diagnostics purposes.

Setting the PROFIBUS address

Two methods are available for setting the PROFIBUS address:
1. Via the PROFIBUS address switches on the Control Unit
– In this case, p0918 is read-only and simply displays the set address.
– A change is not effective until POWER ON.
2. Via p0918
– You can only use this method when all the PROFIBUS address switches from S1 to
S7 are set to ON or OFF.
– Address changes made via parameters must be saved in a non-volatile memory using
the "Copy from RAM to ROM" function.
– A change is not effective until POWER ON.
Example:
Setting the PROFIBUS address using the PROFIBUS address switches on the Control Unit.

 Communication
9.3 Communication via PROFIBUS DP

Note
The factory settings are "ON" or "OFF" for all switches. With these two settings, the
PROFIBUS address is set by parameterization.
Parameter p0918 is unique to the Control Unit (see Control Unit). The factory setting is 126.
Address 126 is used for commissioning. Permitted PROFIBUS addresses are 1 ... 126.
If more than one CU is connected to a PROFIBUS line, the address settings must differ from
the factory settings. Note that each address can only be assigned once on a PROFIBUS
line. This can be achieved using the address switch or by adjustable parameter p0918
accordingly. The setting can be made by connecting the 24 V supply step by step and
resetting p0918, for example.
The address setting on the switch is displayed in r2057.
Each change made to the bus address is not effective until POWER ON.

Device master file

A device master file provides a full and clear description of the features of a PROFIBUS
slave.
The GSD files can be found at the following locations:
● On the CD for the STARTER commissioning tool
Order no. 6SL3072-0AA00-0AGx

Device identification
An identification parameter for individual slaves facilitates diagnostics and provides an
overview of the nodes on the PROFIBUS.
The information for each slave is stored in the following CU-specific parameter:

Bus terminating resistor and shielding

Reliable data transmission via PROFIBUS depends, amongst other things, on the setting for
the bus terminating resistors and the shielding for the PROFIBUS cables.
● Bus terminating resistor
The bus terminating resistors in the PROFIBUS plugs must be set as follows:
– First and last nodes in the line: switch on terminating resistor
– Other nodes in the line: switch off terminating resistor
● Shielding for the PROFIBUS cables
The cable shield in the plug must be connected at both ends with the greatest possible
surface area.

9.3.2.2 Commissioning procedure

Preconditions and assumptions for commissioning

PROFIBUS slave
● The PROFIBUS address to be set for the application is known.
● The telegram type for each drive object is known by the application.
PROFIBUS master
● The communication properties of the SINAMICS S110 slave must be available in the
master (GSD file or Drive ES slave OM).

Commissioning steps (example with SIMATIC S7)

1. Set the PROFIBUS address on the slave.
2. Set the telegram type on the slave.
3. Carry out the following in HWConfig:
– Connect the drive to PROFIBUS and assign an address.
– Set the telegram type.
The same telegram type as on the slave should be set for every drive object
exchanging process data via PROFIBUS.
The master can send more process data than the slave uses. A telegram with a larger
PZD number than is assigned for the drive object STARTER can be configured on the
master. The PZDs not supplied by the drive object are filled with zeros.
The setting "without PZD" can also be defined on a node or object.
4. The I/O addresses must be assigned in accordance with the user program.

9.3.2.4 SIMATIC HMI addressing

You can use a SIMATIC HMI as a PROFIBUS master (master class 2) to access SINAMICS
directly. With respect to SIMATIC HMI, SINAMICS behaves like a SIMATIC S7. For
accessing drive parameters, the following simple rule applies:
● Parameter number = data block number
● Parameter sub-index = bit 0 ... 9 of data block offset
● Drive object number = bit 10 ... 15 of data block offset

Pro Tool and WinCC flexible

The SIMATIC HMI can be configured flexibly with "Pro Tool" or "WinCC flexible".
The following specific settings for drives must be observed when configuration is carried out
with Pro Tool or WinCC flexible.
Controllers: Protocol always "SIMATIC S7 - 300/400"

• The "variable" HMI functions can be used for drive units. Other functions cannot be used
(e.g. "messages" or "recipes").
• Individual parameter values can be accessed. Entire arrays, descriptions, or texts cannot

9.3.2.5 Monitoring: telegram failure

Description
After a telegram failure and the additional monitoring time has elapsed (p2047), bit r2043.0 is
set to "1" and alarm A01920 is output. Binector output r2043.0 can be used for an
emergency stop, for example.
After a delay time has elapsed (p2044), fault F01910 is output. Fault F01910 triggers fault
response OFF3 (quick stop) for SERVO. If no OFF response is to be triggered, the fault
response can be reparameterized accordingly.
Fault F01910 can be acknowledged immediately. The drive can then be operated even
without PROFIdrive.

Sequence of data transfer to closed-loop control system

1. Position actual value G1_XIST1 is read into the telegram image at time TI before the start
of each cycle and transferred to the master in the next cycle.
2. Closed-loop control on the master starts at time TM after each position controller cycle
and uses the current actual values read previously from the slaves.
3. In the next cycle, the master transmits the calculated setpoints to the telegram image of
the slaves. The speed setpoint command NSOLL_B is issued to the closed-loop control
system at time TO after the beginning of the cycle.

Setting criteria for times

● Cycle (TDP)
– TDP must be set to the same value for all bus nodes.
– TDP > TDX and TDP > TO
TDP is thus large enough to enable communication with all bus nodes.

NOTICE
After TDP has been changed on the PROFIBUS master, the drive system must be
switched on (POWER ON) or the parameter p0972=1 (Reset drive unit) must be set.

● TI and TO
– Setting the times in TI and TO to be as short as possible reduces the dead time in the
position control loop.
– TO > TDX + TOmin
Settings and optimization can be done via a tool (e.g. HW Config in SIMATIC S7).

User data integrity

User data integrity is verified in both transfer directions (master ↔ slave) by a sign of life
(4-bit counter).
The sign-of-life counters are incremented from 1 to 15 and then start again at 1.
● Master sign of life
– STW2.12 ... STW2.15 are used for the master sign of life.
– The master sign of life counter is incremented in each master application cycle
(TMAPC).
– The number of sign-of-life errors tolerated can be set via p0925.
– p0925 = 65535 deactivates sign-of-life monitoring on the slave.
– Monitoring
The master sign of life is monitored on the slave and any sign-of-life errors are
evaluated accordingly.
The maximum number of tolerated master sign-of-life errors with no history can be set
via p0925.
If the number of tolerated sign-of-life errors set in p0925 is exceeded, the response is
as follows:
– A corresponding message is output.
– The value zero is output as the slave sign of life.
– Synchronization with the master sign of life is started.
● Slave sign of life
– ZSW2.12 ... ZSW2.15 are used for the slave sign of life.
– The slave sign of life counter is incremented in each DP cycle (TDP).

Setting criteria for times

● Cycle (TDP)
– TDP must be set to the same value for all bus nodes.
– TDP > TDX and TDP > TO
TDP is thus large enough to enable communication with all bus nodes.

NOTICE
After TDP has been changed on the PROFIBUS master, the drive system must be
switched on (POWER ON) or parameter p0972 = 1 (reset drive unit) must be set.

● TI and TO
– Setting the times in TI and TO to be as short as possible reduces the dead time in the
position control loop.
– TO > TDX + TOmin
● A tool can be used for settings and optimization (e.g. HW Config in SIMATIC S7).

User data integrity

User data integrity is verified in both transfer directions (master ↔ slave) by a sign of life (4-
bit counter).
The sign of life counters are incremented from 1 to 15 and then start again at 1.
● Master sign of life
– STW2.12 ... STW2.15 are used for the master sign of life.
– The master sign of life counter is incremented in each master application cycle
(TMAPC).
– The number of sign-of-life errors tolerated can be set via p0925.
– p0925 = 65535 deactivates sign-of-life monitoring on the slave.
– Monitoring
The master sign of life is monitored on the slave and any sign-of-life errors are
evaluated accordingly.
The maximum number of tolerated master sign-of-life errors with no history can be set
via p0925.
If the number of tolerated sign-of-life errors set in p0925 is exceeded, the response is
as follows:
– A corresponding message is output.
– The value zero is output as the slave sign of life.
– Synchronization with the master sign of life is started.
● Slave sign of life
– ZSW2.12 ... ZSW2.15 are used for the slave sign of life.
– The slave sign of life counter is incremented in each DP cycle (TDP).

9.3.4 Slave-to-slave communication

9.3.4.1 General information

Description
With PROFIBUS DP, the master addresses all of the slaves one after the other in a DP
cycle. In this case, the master transfers its output data (setpoints) to the particular slave and
receives as response the input data (actual values). Fast, distributed data transfer between
drives (slaves) is possible using the "slave-to-slave communication" function without
involving the master.
The following terms are used for the functions described here:
● Slave-to-slave communication
● Data Exchange Broadcast (DXB.req)
● Slave-to-slave communication (is used in the following)

Figure 9-23 Slave-to-slave communication with the publisher-subscriber model

Publisher
With the "slave-to-slave communication" function, at least one slave must act as the
publisher.
The publisher is addressed by the master when the output data are transferred with a
different layer 2 function code (DXB.req). The publisher then sends its input data to the
master with a broadcast telegram to all bus nodes.

Function Manual
560 Function Manual, 11/2009, 6SL3097-4AB10-0BP1
 Communication
9.3 Communication via PROFIBUS DP

Subscriber
The subscribers evaluate the broadcast telegrams, sent from the publishers, and use the
data which has been received as setpoints. The setpoints are used, in addition to the
setpoints received from the master, corresponding to the configured telegram structure
(p0922).

Links and taps

The links configured in the subscriber (connection to publisher) contain the following
information:
● From which publishers may input data be received?
● Which input data are there?
● At which location should the input data be used as setpoints?
Several taps are possible within a link. Several input data or input data areas, which are not
associated with one another, can be used as setpoint via a tap.
Links are possible to the device itself. This means, e.g. for a Double Motor Module, data can
be transferred from drive A to B. This internal link corresponds, as far as the timing is
concerned, to a link via PROFIBUS.

Prerequisites and supplementary conditions

The following supplementary conditions should be observed for the "slave-to-slave
communication" function:
● Drive ES Basic V5.3 SP3
● Firmware version ≥ V4.3
● Number of process data, max. per drive
● Number of links to publishers
● Number of taps per link

Applications
For example, the following applications can be implemented using the "slave-to-slave
communication" function:
● Axis couplings (this is practical for isochronous mode)
● Specifying binector connections from another slave

9.3.4.2 Setpoint assignment in the subscriber

Setpoints
The following statements can be made about the setpoint:
● Number of setpoint
When bus communication is being established, the master signals the slave the number
of setpoints (process data) to be transferred using the configuring telegram (ChkCfg).
● Contents of the setpoints
The structure and contents of the data for the "SINAMICS slave" using the local process
data configuring (p0922).
● Operation as "standard" slave
The drive (slave) only receives its setpoints and output data from the master.
● Operation as subscriber
When a slave is operated as a subscriber, some of the setpoints are defined by one or
more publishers rather than by the master.
The slave is informed of the assignment via the parameterization and configuration
telegram when bus communication is being established.

9.3.4.3 Activating/parameterizing slave-to-slave communications

The "slave-to-slave communication" function must be activated both in the publishers as well
as in the subscribers, whereby only the subscriber is to be configured. The Publisher is
automatically activated by the bus system when booting.

Activation in the Publisher

The master is informed abut which slaves are to be addressed as publishers with a different
layer 2 function code (DXB request) via the configuration of the subscriber links.
The publisher then sends its input data not only to the master but also as a broadcast
telegram to all bus nodes.
These settings are automatically made by the S7 software.

Activation in the Subscriber

The slave, which is to be used as Subscriber, requires a filter table. The slave must know
which setpoints are received from the master and which are received from a publisher.
STEP7 automatically generates the filter table.
The filter table contains the following information:
● Address of the publisher
● Length of the process data
● Position (offset) of the input data
● Amount of data
● Target of the data

Configuration telegram (ChkCfg)

Using the configuration telegram, a slave knows how many setpoints are to be received from
the master and how many actual values are to be sent to the master.
For slave-to-slave communication, a special space ID is required for each tap. The
PROFIBUS configuration tool (e.g. HW Config) generates this ID and then transferred with
the ChkCfg in the drives that operate as Subscribers.

Commissioning in STARTER
Slave-to-slave communication is configured in HWConfig and is simply an extension of an
existing telegram. Telegrams can be extended in STARTER (e.g. p0922 = 999).

Figure 9-33 Configuring the slave-to-slave communication links in STARTER

In order to terminate the configuration of slave-to-slave communication for the DOs, the
telegram data of the DOs in STARTER must be matched to those in the HW Config and
must be extended. The configuration is made centrally via the configuration of the respective
CU.

Procedure
1. In the overview for the PROFIBUS telegram, you can access the telegrams of the drive
objects, here SERVO_01. Select the telegram type "Free telegram configuration" for the
configuration.
2. Enter the telegram lengths for the input data and output data according to the settings in
HW Config. For slave-to-slave communication links, the input data comprise the standard
telegram and the slave-to-slave communication data.
3. Then set the telegram in the telegram selection to the standard telegram for drive objects
(in the example: standard telegram 2), which results in a split display of the telegram
types (standard telegram + telegram extension). The telegram extension represents the
telegram portion of slave-to-slave communication.

9.3.4.6 Diagnosing the PROFIBUS slave-to-slave communication in STARTER

Diagnostics
Since the PROFIBUS slave-to-slave communication is implemented on the basis of a
broadcast telegram, only the subscriber can detect connection or data faults, e.g. via the
Publisher data length (see "Configuration telegram").
The Publisher can only detect and report an interruption of the cyclic connection to the DP
master (A01920, F01910). The broadcast telegram to the subscriber will not provide any
feedback. A fault of a subscriber must be fed back via slave-to-slave communication. In case
of a "master drive" 1:n, however, the limited quantity framework (see "Links and requests")
should be observed. It is not possible to have n subscribers report their status via slave-to-
slave communication directly to the "master drive" (Publisher)!
For diagnostic purposes, there are the diagnostic parameters r2075 ("PROFIBUS
diagnostics, receive telegram offset PZD") and r2076 ("PROFIBUS diagnostics, send
telegram offset PZD"). The parameter r2074 ("PROFIBUS diagnostics, receive bus address
PZD") displays the DP address of the setpoint source of the respective PZD.
r2074 and r2075 enable the source of a slave-to-slave communication relationship to be
verified in the Subscriber.

Note
The Subscribers do not monitor the existence of an isochronous Publisher sign of life.

Faults and alarms with PROFIBUS slave-to-slave communication

The alarm A01945 signals that a Publisher of a device (CU) is missing or has failed. Any
interruption to the Publisher is also reported by a fault F01946 at the affected DO. A failure of
the Publisher will therefore only affect the respective DOs.
You will find a description of the two messages in /LH1/ SINAMICS S120/S150 List Manual.

Note: The time between two characters must be shorter than the start delay.

STX
The STX block is a single-byte ASCII STX character (0x02) and indicates the beginning of
the message.

LGE
LGE is a single-byte block and specifies the number of bytes that follow in the telegram. It is
defined as the sum of
● User data characters (quantity n)
● Address byte (ADR)
● Block check character (BCC)
The actual overall telegram is, of course, two bytes longer because STX and LGE are not
counted in LGE.

ADR
The ADR range is a single byte which contains the address of the slave node (e.g. inverter).
The individual bits in the address byte are addressed as follows:

7 6 5 4 3 2 1 0

Special Mirror Send 5 address bits

● Bit 5 is the broadcast bit.

Note
The Broadcast function is not supported in the current software version.

● Bit 6 = 1 indicates a mirror telegram.

The node address is evaluated and the addressed slave returns the telegram to the
master unchanged.
Bit 5 = 0, bit 6 = 0 and bit 7 = 0 indicate normal data communication for devices. The node
address (bit 0 to bit 4) is evaluated.

Parameter value (PWE)

With communication over USS, the number of PWEs can vary. One PWE is required for 16-
bit values. Two PWEs are required if 32-bit values are exchanged.

Note
U8 data types are transferred as U16 with the upper byte set to zero. U8 fields therefore
require one PWE per index.

A parameter channel of 3 words represents a typical data telegram for exchanging 16-bit
data or alarms. The mode with a fixed word length of 3 is used when p2023 = 3.
A parameter channel for 4 words is a typical data telegram for exchanging 32-bit data
variables and requires p2023 = 4.
A parameter channel with a variable length is used with p2023 = 127. The telegram length
between the master and slave can vary in terms of the number of PWEs.
When the length of the parameter channel is fixed (p2023 = 3 or 4), the master must always
send either 3 or 4 words in the parameter channel accordingly. Otherwise the slave will not
respond to the telegram. The response of the slave will also comprise 3 or 4 words. For a
fixed length, 4 should be used because 3 is insufficient for many parameters (i.e. double
words). For a variable length of parameter channel (p2023 = 127), the master will only send
the number of words necessary for the task in the parameter channel. The response
telegram is also no longer than necessary.

Rules for editing requests/responses

● A request or a response can only be referred to one parameter.
● The master must constantly repeat a request until it receives a suitable response.
● The master recognizes the response to a request that it sent by:
– Evaluating the response identifier
– Evaluating the parameter number (PNU)
– Evaluating the parameter index (IND), if necessary, or
– Evaluating the parameter value PWE, if necessary.
● The complete request must be sent in a telegram. Request telegrams cannot be
subdivided. The same applies to responses.
● If response telegrams contain parameter values, the drive always returns the current
parameter value when it repeats response telegrams.

9.4.8 USS process data channel (PZD)

Description
In this area of the telegram, process data (PZD) is continuously exchanged between the
master and slave. Depending on the direction of transmission, the process data channel
contains either request data for the USS slave or response data for the USS master. The
request contains control words and setpoints for the slaves and the response contains status
words and actual values for the master.

The number of PZD words in a USS telegram is defined by parameter p2022. The first two
words are:
● Control word 1 (STW1) and main setpoint (HSW)
● Status word 1 (ZSW1) and main setpoint (HIW)
If P2022 is greater than or the same as 4, the additional control word (STW2) is transferred
as the fourth PZD word (default setting).
The sources of all other PZD are defined by parameter p2051 for an RS485 interface.

All these drive parameters can be read and changed via PROFIBUS using the mechanisms
defined in the PROFIdrive profile.

Parameter categories
The parameters of the individual drive objects are categorized into data sets as follows:
● Data-set-independent parameters
These parameters exist only once per drive object.
● Data-set-dependent parameters
These parameters can exist a multiple number of times for each drive object and can be
addressed via the parameter index for reading and writing. A distinction is made between
various types of data set:
– CDS: Command Data Set
By parameterizing several command data sets and switching between them, the drive
can be operated with different pre-configured signal sources.
– DDS: Drive Data Set
The drive data set contains the parameters for switching between different drive
control configurations.

Saving parameters in a non-volatile memory

The modified parameter values are stored in the volatile RAM. When the drive system is
switched off, this data is lost.
So that the changes can be restored, the data must be saved as follows in a non-volatile
manner in the Control Unit.
● Save parameters - device and drive
p0977 = 1; automatically reset to 0
● Save the parameters with STARTER
See "Copy RAM to ROM" function

NOTICE
The power supply to the Control Unit may first be switched off after saving has finished
(i.e. after saving has started, wait until it has finished and parameter p0977 has the
value 0 once more).

CDS: Command Data Set

The BICO parameters (binector and connector inputs) are grouped together in a command
data set. These parameters are used to interconnect the signal sources of a drive.
By parameterizing several command data sets and switching between them, the drive can
be operated with different pre-configured signal sources.
A command data set contains the following (examples):
● Binector inputs for control commands (digital signals)
– ON/OFF, enable signals (p0844, etc.)
– Jog (p1055, etc.)
● Connector inputs for setpoints (analog signals)
– CI: Speed controller speed setpoint 1 (p1155)
– Torque limits and scaling factors (p1522, p1523, p1528, p1529)
SINAMICS S110 can manage 2 command data sets.
The following parameters are available for selecting command data sets and for displaying
the currently selected command data set:
The binector input p0810 is used to select a command data set.

open and closed-loop drive control:
● Numbers of the assigned motor and encoder data sets:
– p0186: Assigned motor data set (MDS)
– p0187: Assigned encoder data set (EDS)
– p0188: Assigned encoder data set (EDS; for the external encoder)
● Various control parameters, e.g.:
– Fixed speed setpoints (p1001 to p1004)
– Speed limits min./max. (p1080, p1082)
– Characteristic data of ramp-function generator (p1120 ff)
– Characteristic data of controller (p1240 ff)
– ...
The parameters that are grouped in the drive data set are identified in the SINAMICS S110
List Manual by "Data Set DDS" and are assigned an index [0...n].
SINAMICS S110 can manage up to 2 drive data sets. The number of drive data sets is
configured with p0180. The parameters of the drive data sets are switched with an index.
This simplifies the selection between the drive configurations (control type, motor, encoder);
for example, you can switch drive data sets to change between an SMI motor and a second
motor whose encoder is connected via encoder interface X23.
The binector input p0820 is used to select a drive data set.

10.3 Working with the memory card

This chapter describes the basic functions of the memory card for SINAMICS S110.

CAUTION
Switching on the CU305 with the memory card inserted
Depending on the data on the inserted memory card and the CU305, SINAMICS S110
performs certain actions automatically when the system is switched on (see the
descriptions below). Please note the information in these descriptions, as operator errors
may lead to data loss or an incorrect drive response.
If you want to upgrade a number of differently parameterized devices, please use one card
to back up the parameters and another for the firmware update. We only recommend
saving firmware and parameters to the same memory card for the purpose of spare part
installation.

Basics
The CU305, the SINAMICS S110 Control Unit, manages three memory areas:
1. A volatile memory, the RAM, also called working memory.
2. A non-volatile memory, the ROM, also called Flash memory.
3. An optionally available portable memory card. The CU305 only accepts memory cards
which have been prepared for SINAMICS S110 by Siemens.
During operation, SINAMICS S110 uses the work memory. It is here that all project data and
application programs for operation are stored.
To save the current data from the work memory, you must copy it to non-volatile memory
before shutting down. More detailed information appears in "RAM to ROM" in the
commissioning section of this manual.
An optional memory card is used to save a variety of parameter data sets and transfer them
to other S110 systems in order to install firmware updates or carry out series commissioning.
A memory card is absolutely essential if you wish to use the Extended Functions supported
by Safety Integrated.

Parameter data sets

Parameter data sets combine all the parameters for a project, including the project itself.
Parameter data sets differ on the basis of drive configuration (power unit, motor, encoder,
etc. used) and application (e.g. function modules, type of control).
Up to two parameter data sets with the indices 0 and 10 can be saved in the ROM.
Up to 101 parameter data sets (indices 0, ..., 100) can be saved on the memory card.
Parameter data sets can be loaded or copied from the memory card to the ROM.
The parameter data set active in the RAM has the index 0.

There are several ways of copying parameter data sets from non-volatile memory to the
memory card:

Basic information about the drive system
10.3 Working with the memory card

Alternatively, you can back up parameter sets without switching the CU305 off/on as follows:
● The system is switched on:
– Insert a memory card into the CU305.
– Execute command "RAM to ROM" (p0977 = 1). The up-to-date parameter data set is
copied automatically, first to the "ROM" and then to the memory card (in the latter
case as a data set with the index 0). If the memory card already contains a parameter
data set with the index 0, this will be overwritten without a prompt appearing.
● The system is switched on:
The user starts data transmission from the ROM to the memory card with parameters
p0802, p0803 and p0804:
– p0802 = (0...100) as target (to the memory card), p0803 = (0/10/11/12) as source
(from the "ROM"), and p0804 = 1.

Note
RAM to ROM transfer will overwrite the content of an inserted memory card.
When a memory card is inserted, the RAM to ROM command (p0977[1]) will copy the
parameter data set with the index 0 from the ROM to the memory card. Any parameter
data set previously saved to index 0 will be overwritten.

Series commissioning (copying parameter sets)

There are several ways of copying parameter data sets from the memory card to non-volatile
memory:

CAUTION
The parameter data set in the "ROM" is overwritten during system start-up.
Parameters already backed up to the CU305 with the setting 0 will be overwritten during the
following process!

(to the "ROM"), and p0804 = 2.

Note
Saving/loading all parameters via p0976 and p0977:
You can save or reload all parameters via parameters p0976 and p0977. For more
details, refer to the parameter description in the SINAMICS S110 List Manual.

10.3.2 Working with firmware versions

Firmware update/downgrade
The firmware must be updated if the functional scope is extended in a more recent version
and the corresponding functions need to be used.
The firmware must be downgraded if, for example, you want to use a lower version when
installing a spare part on a CU305 already upgraded with a higher version.
A firmware update/downgrade may take a few minutes. The RDY (READY) LED on the
CU305 lights up red (without flashing) to indicate the process is running.
Once all updates/downgrades are complete, the RDY (READY) and COM LEDs on the
Control Unit flash red at a frequency of 0.5 Hz and the relevant RDY (READY) LED on the
component flashes green/red at 2 Hz. To activate the firmware, carry out a POWER ON for
all components.
For automatic updates/downgrades when switching the system off/on, proceed as follows:

CAUTION
Loss of parameters during firmware downgrades
A device's existing parameter settings are lost during a firmware downgrade!

10.3.4 Removing the memory card safely

CAUTION
The file system on the memory card may be destroyed if the card is removed without
requesting and confirming this action in advance via the "Safe removal" function. If this
happens, the memory card no longer works and has to be repaired.

If you want to remove the memory card from the device, proceed as follows:
● Set parameter p9400 = 2.
● Wait until the value of parameter p9400 changes to "3": The memory card can now be
removed safely.
● If the value of parameter p9400 changes to "100", the memory card cannot be removed
safely. Wait until the memory card is no longer being accessed and make a repeat
request for safe removal via p9400 = 2.

10.4 BICO technology: Interconnecting signals

10.4.1 Description

Description
Every drive contains a large number of interconnectable input and output variables and
internal control variables.
BICO technology (Binector Connector Technology) allows the drive to be adapted to a wide
variety of conditions.
Digital and analog signals, which can be interconnected as required by means of BICO
parameters, are identified by the prefix BI, BO, CI, or CO in their parameter name.
These parameters are identified accordingly in the parameter list or in the function diagrams.

Note
The STARTER parameterization and commissioning tool is recommended when using BICO
technology.

10.4.2 Binectors, connectors

Binectors, BI: Binector Input, BO: Binector Output

A binector is a digital (binary) signal without a unit which can assume the value 0 or 1.
Binectors are subdivided into binector inputs (signal sink) and binector outputs (signal
source).

Table 10- 2 Binectors

Abbreviation Symbol Name Description

BI Binector input Can be interconnected to a binector output as

Note
A connector input (CI) cannot be interconnected with any connector output (CO, signal
source). The same applies to the binector input (BI) and binector output (BO).
For each CI and BI parameter, the parameter list shows under "data type" the information
on the data type of the parameter and the data type of the BICO parameter.
For CO parameters and BO parameters, only the data type of the BICO parameter is
shown.
Notation:
Data types BICO input: Data type parameter / Data type BICO parameter
Example: Unsigned32 / Integer16

The possible interconnections between the BICO input (signal sink) and the BICO output
(signal source) are listed in the following documents:
References: SINAMICS S110 List Manual
Section "Explanation of list of parameters", table "Possible combinations for BICO
interconnections".

The BICO parameter interconnection can be implemented in different command data sets
(CDS). The different interconnections are activated by switching data sets. Interconnections
across drive objects are also possible.

10.6 Exchanging a SINAMICS Sensor Module Integrated

What data are saved in the SINAMICS Sensor Module Integrated?

When supplied, the motor and encoder data that are required to control a motor with the
DRIVE-CLiQ are saved on the EEPROM in the SINAMICS Sensor Module Integrated (in
short: "SMI", with DRIVE-CLiQ interface on the encoder). For encoders with DRIVE-CLiQ
interface, motor and encoder data do not have to be entered when commissioning the
system. The motor and encoder data from the SMI (in short: SMI data) are polled and saved
by the Control Unit when the system is commissioned.

DRIVE-CLiQ Internal
A DRIVE CLiQ Internal (DQI) is a SINAMICS Sensor Module Integrated, which is integrated
in the encoder housing. The encoder and the Sensor Module are combined to form a unit.
The DRIVE-CLiQ connection is used to establish a direct link to the Control Unit or a Motor
Module. Contrary to the SMI, encoder data are saved unchanged in a DQI. The motor data
can be changed.

Situation
A defective Sensor Module Integrated must be replaced.

Solution options
The simplest solution is to install a replacement SMI prepared by the motor manufacturer.
The original drive data are saved on this SMI. The drive is then immediately fully operational.
If this is not possible, then operation can still be continued temporarily with an empty
replacement SMI or an SMI with incorrect data (which must be deleted before installation)
(alarm message A01840 can be ignored). As long as the connected Control Unit is not
switched off, then the original SMI data are available in the Control Unit. The data can be
transferred to the memory card with RAM to ROM - and copied into the replacement SMI at
the next opportunity, e.g. during the next scheduled plant or system downtime.
If the drive is shut down, then all of the data in the volatile memory of the CU is lost. If the
SMI data was not first saved on the memory card, then the drive cannot resume operation
without the correct SMI data, even if the defective SMI was replaced.

NOTICE
The user is responsible for backing up the motor and encoder data of the Sensor Module
Integrated. An automatic data backup is performed for a RAM to ROM data save operation.
After each topology change, back up your latest data on the memory card. When service is
required, the latest data can then be quickly downloaded into a replacement SMI and drive
operation can be resumed.

NOTICE
Only appropriately qualified personnel may mechanically replace a defective Sensor
Module Integrated using a replacement SMI.

10.6.1 Saving the original data of the Sensor Module Integrated

Saving SMI data

SMI data can either be automatically or manually saved on the Control Unit memory card.
Either the data of all SMIs from the target topology can be saved or the data of individual
SMIs (also from the actual topology).
Automatic data save
With the "RAM to ROM" command, all SMI data of the target topology are automatically
saved on the memory card. The user does not have to do anything else. The procedure is
explained below.
Manual data save
Saving SMI data can also be manually initiated using parameters p4690 and p4691, if no
RAM to ROM is carried out. The target directory is the same as for the automatic data save.
With the manual data save, data of an individual SMI can be saved or the data of all SMI of
the connected target topology. The procedure is explained below.

Structure of the motor and encoder data on the memory card

From the file structure, it can be identified as to whether the Control Unit components have
been commissioned, or are additionally available. In the example below, the original data
from the original SMI of the Control Unit are saved with component number "7". If a
replacement SMI with the original data is connected to the same DRIVE-CLiQ port, then it
receives the same component number from the Control Unit as the original SMI previously.
If an SMI is additionally connected to a different DRIVE-CLiQ port of the Control Unit, e.g. in
order to save the original data of this SMI, then it receives a preliminary component number
greater or equal to 200 from the Control Unit, in this example, 205.
When saving with the Control Unit, the file structure located below is automatically created.
If you process the memory card using a card reader, then you must manually save the
component data in the folder "USER/SINAMICSS/SMI_DATA_MAN/C2..". The folder
structure and the names must always be maintained so that the Control Unit can find the
data:

Folder structure overview
The motor and encoder data of an SMI are saved on a memory card in two separate files.
The following properties are coded in the file names:
SMIn0Xzy.bin
n = 1 : Resolver
n = 2 : Incremental sin/cos 1Vpp or absolute encoder Endat
z = b : Last digit of the SMI order number ....0
z = e : Last digit of the SMI order number ....3
y = 1 : Motor data
y = 2 : Encoder data

Example 1:
● SMI file name with encoder data of a resolver, last digit of theSMI order number ....3:
SMI10Xe2.bin
● The associated motor data are saved in this file:
SMI10Xe1.bin
Example 2:
● Motor data of a DRIVE-CliQ internal (DQI); in this particular case, there is only the motor
file:
DQIXe1.bin

10.6 Exchanging a SINAMICS Sensor Module Integrated

Saving data of all Sensor Modules Integrated (p4692 = 1)

All SMI data of the TARGET topology are saved using CU parameter p4692 = 1, "SMI
replacement, save/download data". After the data has been successfully saved, a message
is generated to indicate that the data save was successful: p4692 is set to 10.
If the data was not successfully saved, parameter p4692 is set to a fault value. Information
about fault values, their significance and corresponding counter-measures is provided in the
SINAMICS S120/S150 List Manual.

Saving data of a specific Sensor Module Integrated

1. Determining the component number of the SMI:
If the data of a specific Sensor Module Integrated is to be saved, then you must determine
its component number from the ACTUAL topology view. The data of all SMIs can be saved,
both with component numbers <200 as well as with component numbers >200.

Figure 10-11 Determining the component number of the Sensor Module Integrated from the target topology

2. Saving data of the Sensor Module Integrated (p4690, p4691):

– The component number of the SMI of which the data is to be saved is entered into CU
parameter p4690 (SMI spare part component number). In the example, SMI20 has the
component number 7. As a consequence, p4690 must be set to 7.
– Optionally, the number of the file directory of the SMI in which the data is to be saved
can be entered into CU parameter p4693[0..1] (SMI spare part data backup directory).
– The process is started with p4691 = 1.
– After the data has been successfully saved, a message is generated to indicate that
the data save was successful: p4692 is set to 10.
– If the data was not successfully saved, parameter p4692 is set to a fault value (see
above).

● p4691 Save/download SMI spare part data
● p4692 Save SMI spare part data of all SMIs
● p4693[0...1] SMI spare part data backup directory
● r4694[0...19] SMI spare part data backup motor order number (Order No.)

10.6.2 Obtaining the SMI data

Source of the SMI data

Normally, the original SMI data is backed up on the memory card. From there, it can be
directly loaded into an SMI. However, the data on the memory card can be copied from the
memory card into a PC using a read/write device. The data can then be transferred from this
PC to other approved memory cards.
If the original data is no longer available, you can request it from the manufacturer via the
Internet or you can download it there. It can then be copied from a PC to the memory card of
the control unit using a read/write device.

Contacting the manufacturer

For repair workshops that have been authorized by MC, the Service Center EWN provides
an eMail address to request SMI data:
mailto:MMS_Mailer.nes.mc.aud@siemens.com
You must specify the precise serial number of the motor and the SMI in order to define the
data for the replacement SMI. Alternatively, you can specify the complete motor order
number. You will then receive the motor and encoder data by eMail.
There are two different SMI types in circulation, a so-called SAC module and the new DSAC
module. DSAC -SMI have a ...3 at the end of the order number. If the end digit of the order
number is different to ...3, then it involves an SAC module.

10.6 Exchanging a SINAMICS Sensor Module Integrated

10.6.3 Transferring the original data into a replacement Sensor Module Integrated
The original data of the defective SMI were backed up on a memory card.
The replacement SMI is either
● an empty, identical SMI module or
● an SMI module of the same type from a reserve motor, however, with the incorrect motor
and encoder data.

Transferring data into an empty Sensor Module Integrated

1. The motor and encoder data of the drive were saved on a memory card. Qualified
personnel replace the defective SMI by an empty replacement SMI.
2. The replacement SMI is connected to the same DRIVE-CLiQ port as the defective SMI
previously - and the Control Unit allocates it the same component number.
3. Perform a POWER ON and switch on the system again. The system resumes operation,
as the original data is still available on the Control Unit memory card. The Control Unit
outputs alarm A01840 (SMI: Component without motor data found). The component
number of the SMI that was replaced is specified in the fault value of the alarm ("7" in the
example above). Note this number to download the original data into the replacement
SMI. Initially, this alarm can be ignored. The data can be loaded into the empty SMI at the
next opportunity, e.g. at the next revision.
4. Start the download operation by entering the component number in parameter p4690, in
our example p4690 = 7.
5. Then set p4691 to 2 ("Download SMI spare part data"). The Control Unit then transfers
the data of the specified component number from the memory card into the SMI and after
a successful transfer signals:
p4691 = 9 "SMI data loaded and POWER ON required for component".
If the data transfer was not successful, parameter p4691 is set to a fault value. You can
find the fault values, their significance and the corresponding remedy in the SINAMICS
S120/S150 List Manual.
6. The SMI replacement is completed after POWER ON.

Transferring data into a Sensor Module Integrated that is not empty

Data can only be transferred into an empty SMI. If data is still on the replacement SMI, then
this data cannot be overwritten. The replacement SMI must be cleared before saving new
data. In the event that the data on the replacement SMI is still required, you must manually
save this data before clearing. The data backup is described above.

10.6 Exchanging a SINAMICS Sensor Module Integrated

Deleting Sensor Module Integrated data

The following steps are necessary to clear the SMI:
1. An SMI/DQI can only be cleared if the component number in the ACTUAL topology is
≥200
2. The SMI is inserted in the same DRIVE-CLiQ port as the defective SMI
3. p4690 = 7 (component number) and p4691 = 30 (delete SMI data)
4. The Control Unit sets p4691 to 35 (delete SMI data, confirmation is required)
5. Repeat p4691 = 30 (delete SMI data)
6. The SMI data is now deleted
7. The CU confirms the operation with p4691 = 36 (SMI data deleted and POWER ON is
required for component)
8. Parameter p4691 is set to a fault value if the data were not successfully deleted.
Information about fault values, their significance and corresponding counter-measures is
provided in the SINAMICS S120/S150 List Manual.
9. After the Power ON reset, the previously saved data can be loaded into the replacement
SMI as described above

10.7 System sampling times

10.7 System sampling times

The software functions installed in the system are executed cyclically at different sampling
times.
The sampling times of the functions are pre-assigned automatically when the drive unit is
configured.
● Current controller 250 μs
● Speed controller 250 μs
● Flux controller 250 μs
● Setpoint channel 4,000 μs
● Position controller 1,000 μs
● Positioning 4,000 μs
● Technology controller 4,000 μs
For p0092 = 1, the sampling times are pre-assigned so that isochronous operation together
with a control is possible. If isochronous operation is not possible due to incorrect sampling
time settings, then an appropriate message is output (A01223, A01224). Before the
automatic configuration, parameter p0092 must be set to "1" in order that the sampling times
are appropriately pre-set.
● p0009 Device commissioning, parameter filter
● p0092 Isochronous PROFIBUS operation, pre-assignment/check
● p0097 Selects the drive object type
● p1800 Pulse frequency
● r9780 SI monitoring clock cycle (Control Unit)
● r9880 SI monitoring clock cycle (Motor Module)

10.8 Licensing

10.8 Licensing

Description
SINAMICS S110 requires that a license purchased specifically for this purpose is assigned
to the hardware if the Extended Functions of Safety Integrated are to be used. In doing this
you will receive a license key, which links the Extended Functions of Safety Integrated with
the hardware electronically. In order to assign the license to the hardware, you must have a
memory card (this also has to be purchased separately).
The license key is an electronic license stamp declaring that one or more software licenses
have been purchased.
Actual customer verification of the license for the software that is subject to license is called
a certificate of license.

Note
Refer to the order documentation (e.g. catalogs) for information on basic functions and
functions subject to license.

System response where license is insufficient for an option

An insufficient option license is indicated via the following alarm and LED on the Control Unit:
● A13000 License not sufficient
● RDY LED flashes green/red at 0.5 Hz

NOTICE
The drive system can only be operated with an insufficient option license during
commissioning and servicing.
The drive requires a sufficient license in order for it to operate normally.

System response where license is insufficient for a function module

An insufficient function module license is indicated via the following fault and LED on the
Control Unit:
● F13010 Function module license, not licensed
● The OFF1 response brings the drive to a standstill.
● RDY LED permanently lit

NOTICE
The drive system cannot be operated if the license for a function module is insufficient.
The drive requires a sufficient license in order for it to operate normally.

Entering the license key

Note
You need to insert the memory card into the Control Unit before entering the license key.

With the STARTER commissioning software, the ASCII characters are not entered in code,
but the letters and numbers in the license key can be input directly as they appear on the
license certificate.
In this case, the ASCII coding is processed by STARTER in the background.
Example of a license key:
E1MQ-4BEA = 69 49 77 81 45 52 66 69 65 dec (ASCII characters)
Procedure for entering a license key (see example):
p9920[0] = E 1st character
...
p9920[8] = A 9th character

Note
When changing p9920[x] to the value 0, all of the following indices are also set to 0.

After the license key has been entered, it has to be activated as follows:
● p9921 = 1 Licensing, activate license key
The parameter is automatically reset to 0

Entering the license key with BOP20

If you use the BOP20 to enter the license key, you will need to use the ASCII code for the
key (see above for an example). In the table below, you can enter the characters in the
license key and the corresponding decimal numbers.
