Warnings

CAUTION

Cables must not be connected or disconnected, nor signal tests carried out, while the power is
switched on.

The Varispeed L7 DC bus capacitor remains charged even after the power has been switched off. To
avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out
maintenance. Then wait for at least 5 minutes after all LEDs have gone out.
Do not perform a withstand voltage test on any part of the inverter. It contains semiconductors,
which are not designed for such high voltages.

Do not remove the digital operator while the mains supply is switched on. The printed circuit board
must also not be touched while the inverter is connected to the power.

Never connect general LC/RC interference suppression filters, capacitors or overvoltage protection devices to
the inverter input or output.

To avoid unnecessary over current faults, etc., being displayed, the signaling contacts of any contac-
tor or switch fitted between inverter and motor must be integrated into the inverter control logic
(e.g. baseblock).

This is absolutely imperative!

This manual must be read thoroughly before connecting and operating the inverter. All safety pre-
cautions and instructions for use must be followed.

The inverter must be operated with the appropriate line filters, following the installation instructions
in this manual and with all covers closed and terminals covered.
Only then will adequate protection be provided. Please do not connect or operate any equipment
with visible damage or missing parts. The operating company is responsible for any injuries or
equipment damage resulting from failure to heed the warnings in this manual.

 Safety Precautions and Instructions

„1. General
Please read these safety precautions and instructions for use thoroughly before installing and operating this
inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed.
Live and hot inverter components may be accessible during operation. Removal of housing components, the
digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installa-
tion or operation. The fact that frequency inverters control rotating mechanical machine components can give
rise to other dangers.
The instructions in this manual must be followed. Installation, operation and maintenance may only be carried
out by qualified personnel. For the purposes of the safety precautions, qualified personnel are defined as indi-
viduals who are familiar with the installation, starting, operation and maintenance of frequency inverters and
have the proper qualifications for this work. Safe operation of these units is only possible if they are used
properly for their intended purpose.
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power.
It is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may
still carry dangerous voltages.
Children and other unauthorized persons must not be allowed access to these inverters.
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all persons with
any form of access to the inverters.

„2. Intended Use

Frequency inverters are intended for installation in electrical systems or machines. The systems and machines
must be correspondent wiht the relevant directives and standards. Relevant guidelines like Low Voltage
Directives , Machinery Directives , Emc Directives and other s are to be kept.
The Inverters may be put into operation, when the systems and machines in whitch they are inrested to the
guidelines and laws correspondent.
CE marking is carried out to EN 50178, using the line filters specified in this manual and following the appro-
priate installation instructions.

„3. Transportation and storage

The instructions for transportation, storage and proper handling must be followed in accordance with the tech-
nical data.

„4. Installation
Install and cool the inverters as specified in the documentation. The cooling air must flow in the specified
direction. The inverter may therefore only be operated in the specified position (e.g. upright). Maintain the
specified clearances. Protect the inverters against impermissible loads. Components must not be bent nor insu-
lation clearances changed. To avoid damage being caused by static electricity, do not touch any electronic
components or contacts.

„5. Electrical Connection

Carry out any work on live equipment in compliance with the national safety and accident prevention regula-
tions. Carry out electrical installation in compliance with the relevant regulations. In particular, follow the
installation instructions ensuring electromagnetic compatibility (EMC), e.g. shielding, grounding, filter

3
 arrangement and laying of cables. This also applies to equipment with the CE mark. It is the responsibility of
the manufacturer of the system or machine to ensure conformity with EMC limits.
Contact your supplier or Yaskawa representative when using leakage current circuit breaker in conjunction
with frequency inverters.
In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the
relevant safety and accident prevention regulations. The frequency inverter hardware must not be modified.

CAUTION

If a PM motor is turned by any external force, high voltage is generated in the windings.
• During wiring, maintenance or inspection make sure, that the motor is stopped and can not turn.
• If the inverter is turned off and the motor must be turned, make sure that motor and inverter output are
electrically disconnected.

„6. Inverter Setup

This L7 inverter can drive induction motors as well as permanent magnet motors.
Always select the appropriate control mode:
• For induction motors use V/f, Open Loop Vector or Closed Loop Vector control (A1-01 = 0, 2 or 3).
• For permanent magnet motors use no other control mode than Closed Loop Vector for PM (A1-01 = 6).
A wrong control mode selection can damage the inverter and motor.

If a motor is exchanged or operated the first time, always set up the motor control relevant parameters using
the nameplate data or perform autotuning. Do not change the parameters recklessly. To ensure a safe operation
with PM motors always set the:
• correct motor data
• the PG open detection parameters
• the speed deviation detection parameters
• the over acceleration detection parameters
Wrong parameter settings can cause dangerous behavior or motor and inverter damage.

CAUTION

If a permanent magnet motor is used, the peak current capability of the motor should always be higher than
the maximum inverter output current in order to prevent a demagnetization of the motor.

Refer to page 4-2, Start Up for details about the correct start up procedure.

„7. Notes
The Varispeed L7 frequency inverters are certified to CE, UL, and c-UL.

 EMC Compatibility

„1. Introduction
This manual was compiled to help system manufacturers using Yaskawa frequency inverters to design and
install electrical switch gear. It also describes the measures necessary to comply with the EMC Directive. The
manual's installation and wiring instructions must therefore be followed.
Our products are tested by authorized bodies using the standards listed below.
EN 61800-3:2004

„2. Measures to Ensure Conformity of Yaskawa Frequency inverters to the EMC Direc-
tive
Yaskawa frequency inverters do not necessarily have to be installed in a switch cabinet.
It is not possible to give detailed instructions for all of the possible types of installation. This manual therefore
has to be limited to general guidelines.
All electrical equipment produces radio and line-borne interference at various frequencies. The cables pass
this on to the environment like an aerial.
Connecting an item of electrical equipment (e.g. drive) to a supply without a line filter can therefore allow HF
or LF interference to get into the mains.
The basic countermeasures are isolation of the wiring of control and power components, proper grounding and
shielding of cables.
A large contact area is necessary for low-impedance grounding of HF interference. The use of grounding
straps instead of cables is therefore definitely advisable.
Moreover, cable shields must be connected with purpose-made ground clips.

„3. Laying Cables

Measures Against Line-Borne Interference:
Line filter and frequency inverter must be mounted on the same metal plate. Mount the two components as
close to each other as possible, with cables kept as short as possible.
Use a power cable with well-grounded shield. Use a shielded motor cable not exceeding 20 meters in length.
Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (e.g.
metal plate).
Shielded Cable:
–Use a cable with braided shield.
–Ground the maximum possible area of the shield. It is advisable to ground the shield by connecting the cable
to the ground plate with metal clips (see following figure).

5
 Ground clip Ground plate

The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and paint.
–Ground the cable shields at both ends.
–Ground the motor of the machine.

„Installation inverters and EMC filters

For an EMC rules compliant installation consider

Installing a Moulded-Case Circuit Breaker
If a moulded case circuit breaker is used for the power supply connection (R/L1, S/L2, and T/L3) it must be
suitable for the Inverter.
• The MCCB should have a capacity of 1.5 to 2 times of the inverter's rated current.
• For the MCCB's time characteristics selection the inverter's overload protection (one minute at 150% of
the rated output current) must be considered.

Installing an Earth Leakage Breaker

An earth leakage breaker which is able to detect all kinds of current should be used in order to ensure a safe
earth leakage current detection. 2
• If a special-purpose earth leakage breaker for Inverters is used, it should have an actuating current of at
least 30 mA per Inverter.
• If a standard earth leakage breaker is used, it should have an actuating current of 200 mA or more per
Inverter and a actuating time of 0.1 s or more.

Installing a Magnetic Contactor at the Input

If the power supply for the main circuit is shut off by a control circuit, a magnetic contactor can be used.
The following things should be considered:
• The Inverter can be started and stopped by opening and closing the magnetic contactor on the primary side.
Frequently opening and closing the magnetic contactor may cause an Inverter fault. Do not exceed one
power up per hour.
• When the Inverter is operated using the Digital Operator, automatic operation cannot be performed after
recovery from a power interruption.

Connecting Input Power Supply to the Terminal Block

The input power supply can be connected in any sequence to the terminals R, S or T on the terminal block; the
input phase sequence is irrelevant to the output phase sequence.

Installing an Input AC Reactor

If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase advancing
capacitor is switched nearby, an excessive peak current could flow through the input power circuit, causing an
inverter damage. As a countermeasure an optional AC Reactor the inverter input or a DC reactor at the DC
reactor connection terminals can be installed.
In order to fulfill the EN12015 an AC reactor has to be installed. Refer to Chapter 9, AC Reactors for EN
12015 Compatibility for the available reactors. The AC reactor has to be installed between the power supply
and the EMC filter (like shown in Fig 2.5)

Fig 2.5 AC reactor installation

Installing a Surge Absorber

Always use a surge absorber or diode for inductive loads near the Inverter. Inductive loads include magnetic
contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.

2-13
 „Wiring the Output Side of the Main Circuit
The following precautions should be considered for the output circuit wiring.

Connecting the Inverter and Motor

The output terminals U/T1, V/T2 and W/T3 must be connected according to the motor lead wires U, V and W.
The motor should rotate forward with the forward run command. If not, two of the motor cable wires can be
switched.

Never Connect a Power Supply to Output Terminals

2 A power supply must never be connected to the output terminals U/T1, V/T2, and W/T3. Otherwise the inter-
nal circuits of the Inverter will be damaged.

Never Short or Ground Output Terminals

If the output terminals are touched with bare hands or the output wires come into contact with the Inverter
case, an electric shock or a short circuit may occur.

Do Not Use a Phase Advancing Capacitor

A phase advancing capacitor must never be connected to the inverter output circuit. The high-frequency com-
ponents of the Inverter output may overheat and be damaged and may cause other parts to burn.

Using a Magnetic Contactor

A magnetic contactor (MC) between the Inverter and motor must not be turned ON or OFF during inverter
operation. If the MC is turned ON during the Inverter is operation, a large inrush current will be created and
the inverter’s over current protection may operate.

„Ground Wiring
The following precautions should be considered for the ground connection.
• Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that
of the 400 V Inverter with a ground resistance of less than 10 Ω.
• Ground wires should not be shared with other devices, such as welding machines or power tools.
• A ground wire, that complies with technical standards on electrical equipment must be used. The length of
the ground wire should be as low as possible.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and
the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
• When more than one Inverter is used the ground wires should not be looped.

Wiring Control Circuit Terminals

‹ Wire Sizes
For remote operation using analog signals, the control line length between the Analog Operator or operation
signals and the Inverter should be less than 30 m. The controller wires should always be separated from main
power lines or other control circuits in order to avoid disturbances.
It is recommended to use shielded twisted-pair wires and ground the shield for the largest area of contact
between shield and ground.

wires wires

Fig 2.12 Control Circuit Terminal Connections

The base block circuit is a two channel circuit, i.e. always both channels (terminal BB and BB1) have to
be enabled to enable the inverter output.
INFO
Generally the terminals BB and BB1 can be linked directly at the terminals. However, if an EN81-1 con-
form one motor contactor solution is required, the recommended BB and BB1 terminal wiring depends on
the installation:
1. If the controller and inverter are mounted in the same cabinet the terminals BB and BB1 can be linked
directly at the inverter terminal board. Only one wire from the controller to the inverter base block
input is necessary.
2. If the inverter is mounted separated from the controller cabinet, two physically separated wires for the
BB and BB1 terminal should be used in order to keep redundancy in case of a fault of one of the signal
lines.

2-20
EN81-1 Conform Wiring with One Motor
Contactor
In order to use the L7X with one motor contactor instead of two while keeping compliance to the
EN81-1:1998, the following rules have to be followed:
• The hardware base block function using the terminals BB and BB1 must be used to enable / disable the
drive. The input logic must be PNP.
• If the elevator safety chain is opened, the inverter output must be cut. This means that the base block sig-
nals at the terminals BB and BB1 must be opened, e.g. via an interposing relay.
• The base block monitor function must be programmed for one of the multi-function outputs (H2-†† =
46/47). The regarding digital output contact must be implemented in the contactor supervision circuit of
the controller in order to prevent a restart in case of an inverter base block or motor contactor malfunction.
2
• All contactors must be conform to the EN81-1:1998, paragraph 13.2.

 ‹ Control Circuit Wiring Precautions
The following precautions for wiring the control circuits must be considered.
• Control circuit and main circuit wiring should be separated (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/
T2, W/T3, , 1, 2, and 3, PO, NO) and other high-power lines.
• The wiring for control circuit terminals MA, MB, MC, M1, M2, M3, M4, M5, and M6 (contact outputs)
should be separated from wiring to other control circuit terminals.
• If an optional external power supply is used, it should be a UL Listed Class 2 power supply.

2 • Twisted-pair or shielded twisted-pair cables should be used for control circuits to prevent operating faults.
• The cable shields should be connected to the ground with the maximum contact area.
• Cable shields have to be grounded on both cable ends.

2-22
Wiring Check

‹ Checks
Check all wiring after wiring has been completed. Do not perform continuity check on control circuits. Per-
form the following checks on the wiring.
• Is all wiring correct?
• Have no wire clippings, screws, or other foreign material been left?
• Are all screws tight?
• Are any wire ends contacting other terminals?

„Wiring Precautions
Consider the following precautions for wiring.
• Shielded twisted-pair wires must be used for signal lines. Use cables which are recommended by the
encoder manufacturer only.
• For the cable connection to the encoder connectors which are recommended by the encoder manufacturer
should be used.
• Ferrules should be used (refer to Table 2.7).
• The signal lines of the PG Speed Control Card should be separated from main power lines and other con-
trol circuits.
• The shield must be connected (green grounding cable of the option card) to the ground terminal to prevent
operational errors caused by noise.
• The wire ends should not be soldered. Doing so may cause contact faults.
• The PG cards power supply must not be used for anything other than the pulse generator (encoder). Using
it for another purpose can cause malfunctions due to noise.
• A separate power supply is required if the PG power supply consumption is higher than 200 mA. (If
momentary power loss must be handled, use a backup capacitor or other method.)
• The PG cards maximum input frequency must not be exceeded. The output frequency of the pulse genera-
tor can be calculated using the following formula.

 ‹ Autotuning Mode

Autotuning automatically measures and sets the required motor data in order to achieve the maximum perfor-
mance. Always perform autotuning before starting operation when using the vector control modes.
When V/f control has been selected, stationary autotuning for line-to-line resistance can be selected only.
When the motor cannot be operated (e.g. if the ropes cannot be removed from the traction sheave), and Open
Loop or Closed Loop Vector Control shall be used, perform stationary autotuning.

„Example of Operation for V/f control

The tuning method for V/f control is fixed to the measurement of the terminal resistance (T1-01=1). Input the
the rated output power and the rated current specified on the nameplate of the motor and then press the RUN
key. The motor data are measured automatically.
3 Always set the above items. Otherwise autotuning cannot be started, e.g. it cannot be started from the motor
rated voltage input display.
A parameter can be changed from the setting displays using the Increment, Decrement, and Shift/RESET
keys. The parameter is saved when the DATA/ENTER key is pressed.
The following flowchart shows a V/f control Autotuning example.

Power Up

‹ Before Power Up
The following points should be checked carefully before the power is switched on.
• The power supply must meet the inverter specification (refer to page 9-2, Specifications by Model).
• The power supply cables must be tightly connected to the right terminals (L1, L2, L3).
• The motor cables must be tightly connected to the right terminals on the inverter side (U, V, W) as well as
on the motor side.
• The braking unit / braking resistor must be connected correctly.
• The Inverter control circuit terminal and the control device must be wired correctly.
• All Inverter control circuit terminals should be switched OFF.
• When a PG card is used, the PG must be wired correctly.

‹ Display after Power Up

 Autotuning
The motor data autotuning function sets the V/f pattern parameters (E1-††), motor data parameters
(E2-††, E5-††) and the encoder data (F1-01) automatically. The steps which have to be performed during
the autotuning depend on the tuning mode selection. Refer to page 5-57, Motor Autotuning: T for an overview
of the autotuning parameters.

‹ Autotuning Mode Selection

The autotuning mode has to be selected according to selected control mode and the mechanical system (motor
no load rotation possible or not). Table 4.1 shows the selectable tuning mode for each control mode.

„Autotuning Modes

Autotuning with Rotating Motor (T1-01 = 0)

This autotuning mode can be used in any Vector control mode. After the motor nameplate data have been
input, the inverter will operate the motor for approximately 1~2 minutes and set the required motor parameters
automatically.

Use this tuning mode only, if the motor can rotate freely which means that the ropes must be removed
and the brake must be open. The gearbox can remain connected to the motor.
IMPORTANT

Autotuning with Not Rotating Motor (T1-01 = 1)

This autotuning mode can be used for Open Loop and Closed Loop Vector control for IM only. The inverter
supplies power to the motor for approximately 1 minute and some of the motor parameters are set automati-
cally while the motor does not turn. The motor no-load current and the rated slip value will automatically be
fine tuned during the first time operation.
Verify the rated slip value (E2-02) and the no-load current (E2-03) after the first run with nominal speed.

Autotuning for Line-to-Line Resistance (T1-01 = 2)

Non-rotating autotuning for line-to-line resistance can be used in V/f control, Open Loop Vector control and
Closed loop Vector control. The Inverter supplies power to the motor for approximately 20 seconds to mea-
sure the motor line-to-line resistance and cable resistance. The motor does not turn during this tuning proce-
dure.

4-4
 Encoder Offset Tuning (T1-01=4)
This tuning mode is available in Closed Loop Vector control for PM motors only. It automatically sets the off-
set between the magnetic pole and the encoder zero postion. It can be used to retune the offset after an encoder
change without changing the motor data settings.

‹ Auto Tuning Precautions

General Precautions:
1. Use rotating autotuning whenever high precision is required or for a motor that is not connected to a
load.
2. Use not rotating autotuning whenever the load cannot be disconnected from the motor (e.g. the ropes
IMPORTANT
can’t be removed).
3. Make sure, that the mechanical brake is not open for not rotating autotuning.
4. During autotuning the motor contactors have to be closed.
5. For autotuning the BB and BB1 signals must be ON (Inverter must not be in base block condition).
6. Confirm, that the motor is mechanically fixed and can not move.
7. Power is supplied during auto tuning, even though the motor does not turn. Do not touch the motor
until autotuning has been completed.
8. Remove the feather key from the motor shaft before performing a tuning with rotating motor with a
stand alone motor (no traction sheave or gear mounted).
9. To cancel autotuning, press the STOP key on the Digital Operator.

Precautions for rotating and encoder offset autotuning:

4
1. The load should be disconnected which means, that the ropes have to be removed and the brake
must be open.
2. If the load can’t be removed, the tuning can be done with a balanced car. The tuning result accuracy
will be lower which can result in a performance loss.
3. Make sure that the brake is open during autotuning.
4. During autotuning the motor can be started and stopped repeatedly. When the tuning is
finished, “END” will be displayed in the operator panel. Do not touch the motor until this
display is shown and the motor has completely stopped.

‹ Precautions for Induction Motor Autotuning

If the Motor Rated Voltage is Higher than the Power Supply Voltage
If the motor rated voltage is higher than the power supply voltage, lower the base voltage value like shown in
Fig 4.5 to prevent saturation of the Inverter’s output voltage. Use the following procedure to perform autotun-
ing:
1. Input the voltage of the input power supply to T1-03 (Motor rated voltage).
2. Input the results of the following formula to T1-05 (Motor base frequency):
T1-03
T1-05 = Base frequency from motor nameplate × -----------------------------------------------
Motor rated voltage

3. Perform autotuning.
After the completion of autotuning, set E1-04 (Max. output frequency) to the base frequency from the motor’s
nameplate.

Fig 4.5 Motor Base Frequency and Inverter Input Voltage Setting

If speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor rated
voltage) to the input power supply voltage × 0.9. In this case at high speeds the output current will increase as
the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter current.

If the Maximum Frequency is Higher than the Motor Base Frequency

Set the maximum output frequency in parameter E1-04 after autotuning has been performed.

 ‹ Autotuning Alarms and Faults

„Data Input Errors

The inverter will show a “Data Invalid” message and will not perform autotuning if:
• the motor speed, rated frequency and pole pair number do not correspond.
Base Frequency ⋅ 60
Motor Speed < -------------------------------------------------
2 ⋅ Motor pole

• the rated current does not correspond to the rated power value
The inverter calculates the motor power using the input current value and data from the internal motor data
table. The calculated value must be between 50% and 150% of the input value for the rated power.

 Carrier Frequency Derating and
Current Limitation

‹ Carrier Frequency Setting

The carrier frequency selection has a direct influence on the motor noise. The higher the carrier frequency the
lower is the motor noise. On the other hand the overload capability of the inverter is reduced with a higher car-
rier frequency. Both have to be considered when the setting is changed.

„Carrier Frequency Selection

The factory setting is 8 kHz for units from 3.7 to 22 kW and 5 kHz for units from 30 to 55 kW. Usually the
value has not to be changed. However, if it necessary to change it, observe the following precautions:
• If speed and torque oscillate at low speeds: Lower the carrier frequency.
• If inverter noise affects peripheral devices: Lower the carrier frequency.
• If leakage current from the Inverter too is large: Lower the carrier frequency.
• If metallic noise from the motor is large: Increase the carrier frequency.

„Carrier Frequency and Inverter Overload Capability

6 If the carrier frequency is increased the rated current is decreased and vice versa (refer to page 9-6, Carrier
Frequency Derating). The overload capability is always 150% of the derated inverter current for 30 sec. If this
over load limit is exceeded the inverter trips with an inverter overload fault (OL2).

‹ Current limitation level at low speeds

The Varispeed L7 limits the output current at low frequencies. This current limitation does not change with the
carrier frequency selection. The current limitation in the low frequency range is as follows.

Fig 6.1 Low frequency current limitation

• If the torque at low frequencies is too low, check whether the current runs into the limitation explained
above. If so, check the motor data settings (E2-††) and the V/f pattern (E1-††).
• If the current still runs into the limit it might be necessary to install a one size bigger inverter.
IMPORTANT • For selecting an inverter please consider the low frequency current limit as described above and select
an inverter with an appropriate current margin.

‹ Up and Down Commands

„Travel start in Up or Down direction

UP and Down commands are the travel direction information.
To start in the elevator in Up or Down direction the following conditions have to be fulfilled:
• At least one speed reference must be selected if digital inputs are used for speed reference selection.
• The hardware base block signal must be set (not base block condition).
• When a digital input is set as contactor confirmation input, the contactor confirmation signal must be
present before the travel starts.
• To start in the Up direction the Up signal must be set. To start in the Down direction the Down signal must
be set.

„Travel stop
The inverter can be stopped as follows:
• The direction command (UP or Down) signal is removed.
• The speed reference selection signal is removed if digital inputs are used for speed reference selection.
• If d1-18 is set to 3 and all speed inputs are removed

„Up / Down Command Source Selection

The input source for the Up and Down signal can be selected in parameter b1-02.

„Inspection Run Selection by Digital Input

The inspection run digital input must be set before the Up/Down signal is set. During the start of the inspec-
6
tion RUN, the normal brake sequence is used and the inverter accelerates to the inspection speed (d1-14). The
stop method depends on the setting of parameter S3-03.

„Inspection Speed Selection by Comparison Value

Using this function the inverter can detect the inspection speed by the selected speed reference. The speed
must be selected before the Up/Down signal is set. If S3-04 < selected speed O S3-19 the selected speed is
regarded as inspection speed. The normal start sequence is used, the stop method depends on the setting of
parameter S3-03.

„Inspection Run Stop Behavior

S3-03 = 0.0 sec., Stop without deceleration ramp

The inverter stops when the Inspection Speed command or the Up/Down command is removed. In this case:
• The inverter output is cut by baseblock immediately
• The brake open signal is removed immediately
• The contactor control output is removed immediately

• the AI-14B Ch2 and Ch3 input functions must not be set to 14. (H3-05/09 ≠ 14, torque reference not
selected)

The timing chart above is divided in time zones. The following table explains the sequence in each time zone.
Timing Description
The inverter gets the direction signal (UP/DOWN)
The inverter gets the hardware base block disable signal (Not BB condition).
The inverter receives the speed reference signal.
t1
The inverter sets the contactor closed signal.
The inverter waits for the contactor confirmation signal. If no digital input is set to contactor confirmation
signal (H1-††=86), the sequence is proceeded after exceeding the operation start delay time (S1-16).
When the RUN delay time (S1-16) has elapsed, DC injection (Open Loop) or zero servo operation (position lock in
t2 Closed Loop) is started.
When the brake open delay time (S1-06) has elapsed, the inverter sets the brake open command.
The inverter keeps DC injection/zero speed operation until
t3 * the time S1-04 – S1-06 has elapsed if S1-06 < S1-04 or
* the time S1-06 has elapsed if S1-06 > S1-04 (try to avoid this setting since the motor could be driven against the brake)
t4 The speed is increased to the selected speed and is kept constant until the leveling speed is selected.
The speed is decreased to the leveling speed and is kept constant until the stop signal is given (depending on d1-18 either
t5 by removing the direction signal, by removing the leveling signal or by deleting the speed inputs, see page 6-5, Speed
Selection Sequence Using Digital Inputs)
t6 The speed is decreased to the zero speed level.
When the zero speed level is reached (S1-01), the DC injection (Open Loop) or zero servo operation (position lock in
t7 Closed Loop) is applied for the time set in S1-05.
When the brake close delay time (S1-07) has elapsed, the brake open command is removed.
The inverter continues DC Injection (Open Loop) or zero speed operation (Closed Loop) until the time S1-06 – S1-07 has
t8
elapsed. After that the inverter output is shut down and the hardware base block signal must be set.
t9 After the output contactor open delay time (S1-19) has elapsed, the output contactor close signal is removed.

„Brake Sequence with Torque Compensation at Start
(Closed Loop Vector for IM and PM only)

Torque Compensation function

If a load measuring device is installed in the elevator, an analog input can be used to input a torque compensa-
tion value to the inverter. This function requires Closed Loop Vector control for IM or PM.
The input torque compensation value is latched when the direction command is given. At the start it is
increased from zero to the latched value using the torque increase time set in parameter S1-22. The torque
compensation value fades out to 0 using the time constant S1-30 after the speed has reached the torque com-
pensation fade out level.
The torque compensation function can be adjusted using the parameters shown in the block diagram below.
Adjust the parameter so that the torque compensation value is zero when the elevator is balanced.

The torque compensation input source can be selected as follows:

• the channel Ch1 of an AI-14B option card can be used, if b1-01 is not set to 1 (speed reference source is
6
not the A1 input) and the A1 function is selected for torque compensation (H3-15=1)
• one of the input channels Ch2 or Ch3 of an AI-14B option card can be used when the input function for is
set to “Torque Compensation” (H3-05 or H3-09=14). The setting of b1-01 has no influence here.

Timing Description
The inverter gets the direction signal (UP/DOWN)
The inverter gets the hardware base block signal disable signal (Not BB condition).
The inverter receives the speed reference signal.
t1
The inverter sets the contactor close signal.
The inverter waits for the contactor confirmation signal. If no digital input is set to contactor confirmation
signal (H1-††=86), the sequence is proceeded after exceeding the operation start delay time (S1-16).
The zero speed control operation is started.
The analog torque compensation input is latched and the torque compensation value is increased from zero to the latch
t2
value using the time constant set in parameter S1-22.
After reaching the torque compensation level at start, the inverter sets the brake open command.
t3 The brake opens and the zero speed operation (no position lock) is continued until S1-04 has elapsed.
The speed is increased to the selected speed and is kept constant until the leveling speed is selected.
t4 During acceleration, when the torque fade out speed level S1-29 is reached, the torque compensation value is fade out to 0
using the time constant set in S1-22.
The speed is decreased to the leveling speed and is kept constant until the stop signal is given (depending on d1-18 either by
t5 removing the direction signal, by removing the leveling signal or by deleting the speed inputs, see page 6-5, Speed Selection
Sequence Using Digital Inputs).
t6 The speed is decreased to the zero speed level.
When the Zero Speed Level (S1-01) is reached, zero servo operation (position lock in Closed Loop) is applied for the time
t7
set in S1-05. When the brake close delay time (S1-07) has elapsed, the brake open command is removed.
The inverter continues the zero speed operation until the time S1-06 – S1-07 has elapsed. After that the inverter output is
t8
shut down and the hardware base block signal must be set.
t9 After the output contactor open delay time (S1-19) has elapsed, the output contactor close signal is removed.

Torque Limit Fade Out Function (Closed Loop Vector for PM)
The torque limit fade out function smoothly reduced the torque limit to 0 after the zero speed time at stop has

6 elapsed. It thereby can help to prevent shocks or vibrations when the motor stops and the brake is closed. The
used time constant can be set in parameter S1-31. The function can be used in Closed Loop Vector control for
PM motors only (A1-02 = 6).

„Zero Speed Control / Zero Servo (position lock)

In Closed Loop Vector control the inverter uses zero speed or zero servo control during the brake open or
close procedure.

Zero Speed Control:

The inverter keeps the motor speed at zero, a roll-back is not compensated. This method is used for the start
with a torque compensation value by analog input. The strength of the control can be tuned using the ASR
parameters C5-††. Refer to page 6-33, Automatic Speed Regulator (ASR) (Closed Loop Vector only) for tun-
ing details.

Zero Servo Control:

The inverter tries to keep the rotor position, i.e. a roll back is compensated. This method is used for the start
when no torque compensation is used and always for during stop (without and with torque compensation).
Additionally to the ASR parameters C5-†† the zero servo control can be tuned using the parameter S1-20
(Zero servo gain).
• Increase S1-20 if there is a rollback when the brake opens.
• Decrease S1-20 if vibrations occur when the zero servo function is active.
If a digital output is set to “Zero Servo End” (H2-††=33), this output can be used to signalize, that the rotor
position is within a certain bandwidth around the zero position which can be set in parameter S1-21 (the band-
width is set in PG pulses and must be set 4 times of the allowable actual PG pulses).

6-16
„SE4 Detection
A Brake Answer Fault (SE4 Fault) will be detected when one of the digital multi-function outputs is pro-
grammed to Brake Release command (H2-xx = 40) and one of the digital multi-function inputs is programmed
to Brake Release Check (H1-xx = 79) and both signals do not match for a longer time than set in S1-34 (SE4
Detection Time).
The Brake Asnwer Fault is not detected when:
• the second motor is selected
• S1-34 is set to 0.0 sec
• none of the digital multi-function inputs is set to 79 (Brake Release Check)

6-17
 ‹ Short Floor Operation
The short floor operation is activated if the leveling speed command is set before the nominal speed was
reached. The L7 inverter supports 2 methods of short floor operation:
• Simple short floor operation which can be enabled by setting S3-01 = 1.
When the leveling speed input is set and the reached speed is higher than 40% of the nominal speed, the
inverter decelerates to 40% and keeps this speed for a calculated time before it decelerates to the leveling
speed and finally stops. If the reached speed is below 40% of the nominal speed, the inverter accelerates to
40% speed and keeps it for a calculated time before it decelerates to the leveling speed.
If the leveling input is set during constant speed run and the speed reference is lower than 40% of the nom-
inal speed, the speed is hold for a calculated time in order to minimize the leveling distance. If the speed
reference is higher than 40% but lower than the nominal speed, the speed is decreased to t 40% first, is
hold for a calculated time an then decreased to the leveling speed.
• Advanced short floor operation which can be enabled by setting S3-01 = 2.
If the leveling speed command is set the inverter calculates the optimal speed using the speed reference,
two gain factors (S3-21/22) and a time constant (S3-20). If the leveling input is set before the optimal
speed has been reached, the inverter accelerates to the optimal speed and keeps it for the time constant S3-
20. If the leveling input is set when the optimal speed was exceeded, the inverter keeps the reached speed
for a certain time before it decelerates to the leveling speed.
The table below shows the behavior of the short floor functions under different conditions.

„Simple Short Floor Operation Setup

• The short floor function can be activated by setting parameter S3-01 to 1.
• If parameter d1-18 is set to 0 or 3 (multispeed input), the set value of parameter S3-05 is taken as nominal
speed reference for the short floor calculation. Additionally it is required to use the nominal/leveling speed
detection (refer to page 6-6, Nominal / Leveling Speed Detection with Multi Speed Inputs).
• If parameter d1-18 is set to 1 or 2 (dedicated speed inputs), the value of parameter d1-09 is taken as nomi-
nal speed. The set value of S3-05 has no meaning. The nominal/leveling speed detection must not be used.

„Advanced Short Floor Operation Setup

• The advanced short floor operation can be activated by setting parameter S3-01 to 2.
• If parameter d1-18 is set to 0 or 3 (multispeed input), the speed reference value, which was selected at the
start, is taken as nominal speed for the speed pattern calculation. Parameter S3-04 is used for the leveling
speed detection (refer to page -6).
• If parameter d1-18 is set to 1 or 2 (dedicated speed input), the value of parameter d1-09 is taken as nominal
speed for the speed pattern calculation.

6-19
 Setup the Acceleration and Deceleration Gain (S3-21, S3-22)
These parameters are used for the optimal speed calculation to compensate the S-curves (S-curves are not con-
sidered in the optimal speed calculation).
• Increase the gains S3-21 and S3-22 if the leveling time is too short or the calculated optimal speed is too
high.
• Decreases the gains S3-21 and S3-22 if the leveling time is too short of the calculated optimal speed is too
low.

1. S-Curves are not considered in the optimal speed calculation and have to be compensated by the
gains S3-21 and S3-22.
2. A too low gain setting can result in a too high optimal speed and too short leveling time. Very low
settings can lead to an overrun. Do not set the values lower than 100% (100% means, that the S-
IMPORTANT
curve is not compensated.
3. If parameter d1-18 is set to 0 or 3 and the leveling speed input is released during short floor oper-
ation, the inverter accelerates or decelerates to the selected reference speed.
4. If the Dwell function (b6-†† parameters) is activated, the dwell function is performed during short
floor operation but it is not considered in the optimal speed calculation. The influence of the Dwell
function must be compensated using the gains S3-21 and S3-22.
5. The advanced short floor function does not work during rescue operation and inspection run.
6. If the speed reference is input using an analog input the advanced short floor function should not
be used.
7. If the advanced short floor function is used, the following parameter settings should be in given
range:
9.6 Hz O E1-04 O 100 Hz
4.8 Hz O d1-08 O 100Hz

Acceleration and Deceleration Characteristics

‹ Setting Acceleration and Deceleration Times

The acceleration time indicates the time to increase the speed from 0% to 100% of the maximum speed set in
E1-04. The deceleration time indicates the time to decrease the speed from 100% to 0% of E1-04.
Four separate acceleration and deceleration times can be set. They can be switched over between using:
• digital input signals
• the automatic accel./decel. time switch over function with a changeable switching speed level
The display unit and the setting range for the times can be selected between 0.0 sec. or 0.00 sec.

„Dwell at Start Function (Closed Loop Vector only)

The Dwell function can be used to reduce a staring jerk caused by high static friction.
After a start command, the output frequency is increased up to the Dwell speed set in parameter S1-26 using
the acceleration time C1-07. As soon as the motor starts turning and the motor speed (PG feedback) reaches
the acceleration time switching level C1-11, the acceleration is continued using the selected acceleration time

‹ Stall Prevention During Acceleration

The Stall Prevention During Acceleration function prevents the motor from stalling if the load is too heavy.
If L3-01 is set to 1 (enabled) and the Inverter output current reaches 85% of the set value in L3-02, the accel-
eration rate will begin to slow down. When L3-02 is exceeded, the acceleration will stop.
If L3-01 is set to 2 (optimal adjustment), the motor accelerates so that the current is held at the level set in L3-
02. With this setting, the acceleration time setting is ignored.

• Set the parameters as a percentage taking the inverter rated current to be 100%.
• Do not increase the stall prevention level unnecessarily. An extremely high setting can reduce the inverter
lifetime. Also do not disable the function.
• If the motor stalls with the factory settings check the V/f pattern settings (E1-††) and the motor setup
(E2-††).

„Adjusting Analog Input Signals

The frequency reference can be input from the control circuit terminals using analog voltage. The voltage
level at terminal A1 is 0 to +10V. The analog input channels of the AI-14B option card can be used with 0 to
+10V or -10 to +10V.
The input signal levels can be selected using,
• H3-01 for AI-14B CH1
• H3-04 for AI-14B CH3
• H3-08 for AI-14B CH2

The signals can be adjusted using the parameters:

• H3-02 (Gain) and H3-03 (Bias) for Channel 1 of the AI-14B option card
• H3-06 (Gain) and H3-07 (Bias) for Channel 3 of the AI-14B option card
• H3-10 (Gain) and H3-11 (Bias) for Channel 2 of the AI-14B option card
• H3-16 (Gain) and H3-17 (Bias) for analog input A1
The gain sets the level of the selected input value if 10V is input, the bias sets the level of the selected input
value if 0V is input.

 Improving the Operation Performance

‹ Reducing the Motor Speed Fluctuation (Slip Compensation Function)

When the load is large, the motor slip also increases and the motor speed decreases. The slip compensation
function keeps the motor speed constant, regardless of changes in load. When the motor is operating at the
rated load, parameter E2-02 (Motor Rated Slip) × the slip compensation gain value in parameter C3-01 is
added to the output frequency. The function can be used in V/f control or Open Loop Vector control.

„Adjusting Slip Compensation Gain (C3-01)

If C3-01 is set to 1.0, the slip compensation value at 100% load is equal to the rated slip set in parameter
E2-02.
If necessary (motor speed is too high or too low) adjust the slip compensation gain as follows:
1. With Open Loop Vector control set E2-02 (Motor Rated Slip) and E2-03 (Motor No-load Current). The
motor rated slip can be calculated using the values on the motor nameplate and the following formula:
Rated motor speed (rpm) × Number of motor poles
6 slip (Hz) = Motor rated frequency (Hz) – ----------------------------------------------------------------------------------------------------------------------------

The motor data can be set automatically using the autotuning function.
120

2. With V/f control set C3-01 to 1.0.

3. Apply a load and compare the speed reference and the actual motor speed during run with constant speed.
Adjust the slip compensation gain by 0.1 at a time. If the speed is less than the target value, increase the
slip compensation gain, if the speed is higher than the target value, reduce the slip compensation gain.
4. Setting C3-01 to 0.0 disables the slip compensation function.

„Adjusting Slip Compensation Primary Delay Time Constant (C3-02)

The slip compensation delay time constant is set in ms. The setting value of C3-02 is 2000ms. Normally, there
is no need to change these settings. When the slip compensation responsiveness is low, lower the set value.
When the speed is unstable, increase the set value.

6-30
 „Adjusting Slip Compensation Limit (C3-03)
Using parameter C3-03 the upper limit for the slip compensation can be set as a percentage, taking the motor
rated slip as 100%.
If the speed is lower than the target value but does not change even after adjusting the slip compensation gain,
the slip compensation limit may have been reached. Increase the limit, and check the speed again. Always
make sure that the value of the slip compensation limit and reference frequency does not exceed the tolerance
of the machine.
The following diagram shows the slip compensation limit for the constant torque range and fixed output range.

„Enable the Slip Compensation Function During Regeneration (C3-04)

Enables or disables the slip compensation function during regenerative operation. The factory setting is
enabled.

„Operation Selection when the Output Voltage is Saturated (C3-05)

Generally the Inverter cannot output a voltage that is higher than the input voltage. If in the high-speed range
the output voltage reference for the motor (monitor parameter U1-06) exceeds the input voltage, the output
voltage becomes saturated, and inverter cannot respond to speed or load changes. This function automatically
6
reduces the output voltage to avoid voltage saturation.
Thereby the speed control accuracy can be maintained even at high speeds (around the rated speed of the
motor). By the lowered voltage the current can be around 10% higher compared to the operation without volt-
age limiter.

‹ Torque Compensation Function Adjustments

The torque compensation function detects a rising motor load, and increases the output torque.
In V/f control the inverter calculates the motor primary loss voltage using the terminal resistance value (E2-
05) and adjusts the output voltage (V) to compensate insufficient torque at startup and during low-speed oper-
ation.
The compensation voltage is calculated by the calculated Motor primary voltage loss × parameter C4-01.
In Open Loop Vector control the motor excitation current and the torque producing current are calculated and
controlled separately. The torque compensation affects the torque producing current only.
The torque producing current is calculated by the calculated torque reference × C4-01.

Normally, there is no need to change this setting. If adjustments are necessary do the following:

Open Loop Vector control

• If the torque response is slow increase the set value.
• If vibrations occur decrease the set value.

V/f control
• If the cable is very long, increase the set value.
• If the motor capacity is smaller than the Inverter capacity (max. applicable motor capacity), increase the
set value.
• If the motor vibrates, reduce the set value.

Setting precautions
• Adjust this parameter so that the output current during low-speed rotation does not exceed the Inverter
rated output current range.
• Adjust the value in steps of 0.05 only.

6 „Adjusting the Torque Compensation Delay Time Constant (C4-02)

The factory setting depends on the control mode. The factory settings are:
• V/f control: 200 ms
• Open loop vector control: 20 ms
Normally, there is no need to change this setting. If adjustments are necessary do the following:
• If the motor vibrates or if overshooting occurs, increase the set value.
• If the torque response is slow, decrease the set value.

• The compensation works for motoring operation only. It can not be used for regenerative operation.
• If the starting torque compensation is used and a large shock is generated at the start, increase the starting

‹ Automatic Speed Regulator (ASR) (Closed Loop Vector only)

In Closed Loop Vector control the automatic speed regulator (ASR) adjusts the torque reference in order to
eliminate the deviation between the speed reference and the measured speed (PG feedback). The ASR settings

„ASR Gain and Integral Time Adjustments

There are three sets of ASR gain and integral times, one for the maximum speed (C5-01/02), one for the mini-
mum speed at acceleration (C5-03/04) and one for the minimum speed at deceleration (C5-09/10) (see the fig-
ure below).

During Acceleretion During Deceleretion

When the ride starts with the nominal speed selected, the ASR P gain and I time change from C5-03/04 to C1-
01/02 at nominal speed. When the speed selection changes to leveling speed, the P gain and I time are changed
from C1-01/02 to C1-09/10.
If parameter d1-18 is set to 0 or 3, the nominal/leveling speed detection function must be enabled (refer to
page 6-6, Nominal / Leveling Speed Detection with Multi Speed Inputs) in order to use the ASR 3 settings.

Adjusting ASR Proportional Gains (C5-01/03/09)

The gain settings determine how much the ASR input (= speed deviation) is amplified in order to eliminate the
speed deviation. The responsiveness of the ASR is increased when the gain setting is increased but oscillations
can occur when this setting is too high.
• Increase C5-03 if the ASR is too slow at start or very low frequencies, decrease it if vibrations occur.
• Increase C5-01 if the ASR is too slow at high speed or if overshooting occurs at speed changes in the high
speed area, decrease it if vibrations occur

6-34
 • Increase C5-09 if ASR is slow in the low speed area or if undershooting occurs at leveling speed. If vibra-
tions occur in the low speed area during deceleration decrease the value.

Adjusting ASR Integral Times (C5-02/04/10)

The integral time determines how fast the ASR input is integrated in order to eliminate the speed deviation.
Lengthening the integral time lowers the responsiveness of the ASR and the speed accuracy when the load
changes suddenly. Oscillations can occur if the setting of this value is too low.
• Decrease C5-02 if a speed deviation is compensated too slow at high speeds or if overshooting occurs at
speed changes in the high speed area. Increase it if vibrations occur.
• Decrease C5-04 if a speed deviation is compensated too slow at start or at very low frequencies. Increase it
if vibrations occur.
• Decrease C5-10 if a speed deviation is compensated too slow in the low speed area at leveling or if under-
shooting occurs at leveling speed. If vibrations occur in the low speed area during deceleration increase the
value.

Adjusting the ASR Gain for Encoder Offset Tuning (C5-11)

During the encoder offset tuning for Hiperfacey or EnDat uses the value of parameter C5-11 as ASR gain.
• Decrease C5-11 if vibrations occur during the tuning and repeat the tuning.
• Increase C5-11 if the accuracy of the tuning is low and repeat the tuning.

‹ Stabilizing Speed (Automatic Frequency Regulator) (Open Loop Vector)

The speed feedback detection control (AFR) function controls the stability of the speed when a load is sud-
denly applied or removed. It calculates the amount of speed fluctuation using the torque current (Iq) feedback
value and compensates the output frequency with the amount of fluctuation. 6

6 Motor acceleration time (n5-02)

The motor acceleration time n5-02 is the time, which is needed to accelerate the to the rated speed with the
rated torque of the motor. The time can be estimated like follows:
• Make the general setup (V/f pattern, Motor Setup, etc.)
• Balance the elevator (car in middle position, Car weight = Counter weight)
• Set the torque limits to 100% using the L7-†† parameters.
• Set the acceleration time very short (the inverter must reach the torque limit very fast).
• Start in any direction and measure the time from zero speed to top speed.
• Set this time in n5-02.

Feed Forward Gain (n5-03)

This value usually has not to be changed.
• Increase the gain to improve the responsiveness to the speed reference.
• Decrease the gain if vibrations occur.

„Motor Acceleration Time Auto Tuning (n5-05)

The motor acceleration time n5-02 can be calculated by an auto tuning function. It sets the internal accelera-
tion time to 0.1 sec., disabled the S-curve and sets the torque limit to 100%. After that a start in each direction
must be performed. The measured acceleration times are used to calculate the n5-03 value.
Before the n5-02 auto tuning is performed, the motor data autotuning and the general setup should have been
finished. Do the tuning with the factory settings for the n5-†† parameters.

6-36
 Use the following procedure:
1. Set n5-05 to “1” to enable the auto tuning and go back to the speed reference display.
2. Set the base block input.
3. Enable the inspection speed input. “FFCAL” will blink in the display to signalize that the calculation is
active.
4. Set an UP command. The inverter will accelerate the motor up to the nominal speed. Release the UP com-
mand a few seconds after the top speed has been reached.
5. When the motor has stopped, apply a DOWN command. The inverter will accelerate the motor in the
opposite direction to the nominal speed. Release the DOWN command a few seconds after the nominal
speed has been reached.
To abort the tuning set parameter n5-05 to “0”.

1. The order of giving the UP or DOWN command has no influence.

2. n5-01 should not be changed from the factory value for the tuning.
3. After the run in both directions is finished, parameter n5-05 is automatically set back to “0”.
IMPORTANT 4. The autotuning will be performed only if the inspection speed input is set.
5. Do not change the mechanical constants (load, inertia) between the runs.

‹ Automatic Current Regulator (ACR) Tuning

„Adjustments
Normally there is no need to change these values. However, if short cycle vibrations occur which can’t be
eliminated by the ASR controller setup, it might help to adjust ACR values like follows:
• If the motor generates very strange high frequency noise (not carrier frequency related), reduce both ACR
gains (n8-29 and n8-32) for the same value. If the gain is reduced too much, the performance will be
reduced.
• If vibrations occur, reduce both integral times (n9-30 and n9-33) for the same value.

‹ Improving the Leveling Accuracy by Leveling Speed Slip Compensation

This function can be used in V/f and Open Loop Vector control to improve the leveling accuracy by compen-
sating the motor slip influence at leveling speed.
The inverter measures the current level or torque reference S2-05 sec. after the speed-agree condition (acceler-
ation finished) for the time set in S2-06 and calculates the average value to estimate the load. This value is
used for the calculation of slip which is added to the speed reference at leveling speed (see Fig 6.14).

„Adjustments
The Slip compensation values can be set separately for motoring and regenerative operation. Before adjusting
this function the general setup should have been done (Motor Setup, V/f pattern, Speeds, ASR settings etc.).
To adjust the Slip compensation function do the following in motoring and regenerative mode:
• Set the motor speed in S2-01 if V/f control is used.
• Try to measure the actual motor speed during leveling.
• If the motor speed is lower than the leveling speed reference increase S2-02 in motoring mode or decrease
S2-03 in regenerative mode.
• If the motor speed is higher than the leveling speed reference decrease S2-02 in motoring mode or increase
S2-03 in regenerative mode.
• S2-05 and S2-06 should not be modified, except if the stop accuracy is poor and the constant speed time
after the speed agree is shorter than S2-05 + S2-06.

‹ Field Forcing 6
The field forcing function controls the motor flux and compensates the flux establishment delay of the motor.
Thereby it improves the motor responsiveness to changes in the speed reference or the load.
Field forcing is applied during all operation conditions except DC Injection.
Using parameter d6-06 a field forcing limit can be applied. A setting of 100% is equal to the no-load current
set in parameter E2-03.

• Increase the corresponding set value when the holding torque during brake open or brake close is too low.
• Decrease the corresponding set value when the holding torque is enough but e.g. the DC injection noise is
too loud.

Adjusting the DC Injection Gains for Stop (S1-17/18)

In Open Loop Vector control two different DC injection current gains for motoring and regenerative operation
6 can be adjusted in order to improve the stopping behavior. The gains are related to the S1-03 set value. The
function can be used to equalize jerk effects if the DC injection is too low with motoring load and too high
with regenerative load. The load condition (regenerative or motoring) is detected when the inverter is running
at another speed than the leveling speed.
• If the DC injection is ok with motoring load but not with regenerative load adjust parameter S1-17.
• If the DC injection is ok with regenerative load but not with motoring load adjust parameter S1-18.

Protective Functions

‹ Preventing Motor Stalling During Operation

Stall prevention during operation prevents the motor from stalling by automatically lowering the inverter out-
put frequency when a transient overload occurs while the motor is operating at a constant speed.
Stall prevention during operation can be enabled in V/f control only. If the Inverter output current continues to
exceed the setting in parameter L3-06 for 100 ms or longer, the motor speed is reduced. Enable or disable the
stall prevention using parameter L3-05. Set the according deceleration times using C1-02 (Deceleration time
1) or C1-04 (Deceleration Time 2).
If the Inverter output current reaches the set value in L3-06 – 2%, the motor will accelerate again to the set fre-
quency.

„Precautions
If the motor capacity is smaller than the Inverter capacity or the motor stalls when operating at the factory set-
tings, lower the stall prevention level during operation.

„Setting Precautions
• Set the parameters as a percentage taking the inverter rated current to be 100%.
6
• Do not increase the stall prevention level unnecessarily. An extremely high setting can reduce the inverter
lifetime. Also do not disable the function.
• If the motor stalls with the factory settings check the V/f pattern (E1-††) and the motor setup (E2-††).
• If the stall level has to be increased very much to get the elevator running, check the mechanical system or
consider using a one size bigger inverter.

‹ Motor Torque Detection / Car Stuck Detection

The inverter provides a torque detection function to detect overtorque (Car stuck) or undertorque. An alarm
signal can be output to the digital output terminals M1-M2, M3-M4, or M5-M6.
To use the overtorque/undertorque detection function, set B, 17, 18, 19 (overtorque/undertorque detection
NO/NC) in one of the parameter H2-01 to H2-03 (digital output terminals M1 to M6 function selection).
Overtorque/undertorque is detected by:
• observing the output current in V/f control (the inverter rated output current is equal to 100%).
• observing the torque reference value in Open Loop and Closed Loop Vector control (the motor rated
torque is equal to 100%).

„Car Stuck Detection (OL3, Using the Overtorque detection)

The Over torque detection function can be used to detect a stuck car. The torque detection function 1 can be
used for this. Therefore a digital output has to be set to “Over torque detection 1” (H2-†† = B or 17). Using
this with the factory settings a car stuck is detected (output is switched) when the torque/current is higher than
150% for 10 sec. The level can be adjusted in L6-02, the time in L6-03. The output is switched of and an OL3
fault will be indicated (see Fig 6.17)

„Using a Digital Output to Signalize Operation at the Torque Limit

If a multifunction output is set to this function (H2-01 to H2-03 is set to “30”), the output is switched ON
when the motor output torque reaches one of the torque limits.

6-44
 „Adjusting the Torque Limit Integral Time (L7-06)
In Open Loop Vector control, during constant speed the limit function works with an integral control part
(during acceleration and deceleration just a P-control is used). Normally there is no need to change this set-
ting.
• Increase the setting if vibrations or short cycle oscillations occur when the motor is running at the set
torque limit
• Decrease the setting if long cycle oscillations occur when the motor is running at the set torque limit.

„ Enabling the Torque Limit Integral Operation during Accel./Decel. (L7-07)

In Open Loop Vector control an integral operation can be applied to the torque limit function (P-control is
standard). This improves the torque limit responsiveness and smoothes the torque limit operation. To enable
the integral operation set parameter L7-07 to 1. The integral time set in parameter L7-07 is used.

„Setting Precautions
• When the output torque reaches the torque limit, control and compensation of the motor speed is disabled
to prevent the output torque from exceeding the torque limit. The torque limit has the priority.
• The torque limit accuracy is ±5% at an output frequency of 10 Hz or above. When output frequency is
lower than 10 Hz, the accuracy is lower.

Set the rated current value on the motor nameplate in parameters E2-01 (for motor 1), E4-01 (for motor 2) or
E5-02 (PM motor). This set value is the base current for the internal thermal overload calculation.

6-45
 „Setting Motor Overload Protection Characteristics (L1-01)
Set the overload protection function in L1-01 according to the used motor.
As the motors thermal behavior depends on the motor type, the thermal motor protection characteristics must
be properly selected.
Set L1-01 to:
0: to disable the thermal motor protection function.
1: to enable the thermal motor protection for a fan cooled general purpose motor (self-cooled).
2: to enable the thermal motor protection for an inverter motor (externally cooled).
3: to enable the thermal motor protection for a special vector motor (externally cooled).
5: to enable the thermal motor protection for a permanent magnet motor

„Setting Motor Protection Operation Time (L1-02)

The motor protection operation time is the time for that the motor can handle a 150% overload when it was
running with the rated load before (i.e. operating temperature was reached before applying the 150% over-
load). Set the motor protection operation time in L1-02. The factory setting is 60 sec.
Fig 6.19 shows an example of the characteristics of the electronic thermal protection operation time (L1-02 =
1.0 min., operation at 50 Hz, general-purpose motor characteristics, when L1-01 is set to 1)

H2-03 (output terminals M1-M2, M3-M4, and M5-M6 function selection) to 1F (motor overload OL1 pre-
alarm), the motor overload pre-alarm will be output at the selected terminals. If the electronic thermal value
reaches minimum 90% of the overload detection level, the output terminal that has been set will be turned ON.

SE2 fault (SE2, Current observation at start)

The current is measured for the time S1-06 + S1-14 (Brake open delay plus SE2 detection time) after the Up/

S1-06 + S1-14 must be smaller than S1-04 (DC injection at start).

SE3 fault (SE3, Current observation during Run)

When the acceleration is started (DC injection/Zero Speed time S1-04 after the Up/Down command input), the
inverter observes the output current continuously. If it falls below 25% of the motor no-load current (E2-03) a
SE3 fault is output.

‹ Over Acceleration Detection (“DV6” Fault Detection)

Using this function an over acceleration of the car caused by too high load or wrong settings can be detected.
6
The function works in Closed Loop Vector for PM motors only (A1-02 = 6). If an over acceleration is
detected, the inverter stops and a “DV6” fault is displayed.

„Adjusting the Over Acceleration Detection

Over acceleration is detected when the acceleration of the car exceeds the value set in S3-16 for longer than
the time set in S3-17. The setting of parameter S3-18 decides the over acceleration is always activate if the
power supply is on (S3-16 = 0) or only during run (S3-16 = 1).
Setting parameter S3-16 to 0.0 m/s² disables the over acceleration detection.

It is imperative to set up the parameters S3-13, S3-14 and S3-15 (traction sheave diameter, roping and
gear ratio) in order to make this function working properly!

 Inverter Protection

‹ Inverter Overheat Protection

The Inverter is protected against overheating using a thermistor that detects the heatsink temperature.
When the overheat temperature level is reached the inverter output is switched off.
To prevent a sudden and unexpected stop of the inverter due to an over temperature, an overheat pre-alarm can
be output. The temperature level for that pre-alarm can be set in parameter L8-02. Using parameter L8-03 the
inverter operation when an over temperature occurs can be selected.
If a multifunction output is set to this function the output is switched ON when the heatsink temperature
exceeds the overheat pre-alarm level set in L8-02.

This function detects an open output phase by comparing the output current value of each phase with the out-
put open phase detection level (5% of inverter rated current). The detection does not work when the output fre-
quency is below 2% of the base frequency.
Three settings are available:
• L8-07=0, no output open phase detection
• L8-07=1, the loss of one phase is detected only
• L8-07=2, the loss of 2 or 3 phases is detected as well
The detection delay time can be set in parameter L8-20.

„Hardware Baseblock
When hardware baseblock is activated, the power supply of the IGBT driver circuit is cut off and the motor
starts to coast. To use this baseblock function the digital input S8 must be used. The input is a NC input, i.e. if
terminal S8 is open, the inverter is base block condition.

„Software Baseblock
When software baseblock is used, the inverter output is cut by a software function. To use this baseblock func-
tion one of the digital inputs must be set to baseblock, i.e. one of the parameters H1-01 to H1-05 (digital input
terminal S3 to S7 function selection) must be set to 8 or 9 (Baseblock command NO/NC). The input can be
used with a NC as well as with a NO contact.

„Baseblock Restart Behavior

If baseblock is activated, the inverter output is immediately stopped. Using parameter S1-12 it can be selected,
whether the Up/Down command input has to be cycled to restart when the baseblock is disabled or not.

‹ Stopping the Inverter on External Device Errors (External Fault Function)

The external fault function activates the fault contact output and stops the Inverter operation. Using this func-
tion the inverter operation can be stopped by the break down of peripheral devices or other external errors. The
6
digital operator will display EFx (External fault [input terminal Sx]). The x in EFx shows the number of the
terminal at which the external fault signal is input. For example, if an external fault signal is input to terminal
S3, EF3 will be displayed.
To use the external fault function, set one of the values 20 to 2F in one of the parameters H1-01 to H1-05 (dig-
ital input terminal S3 to S7 function selection).
Select the set value for H1-01 to H1-05 by a combination of any of the following three conditions.
• Signal input level from peripheral devices
• External fault detection method
• Operation after external fault detection

If motor 2 is selected, the speed set in d1-19 will be the speed reference. d1-19 has priority over all speed
inputs except the service speed input.
The output signal sequence (brake control, contactor etc.) is the same as for motor 1.
This function is not available for Closed Loop Vector for PM motors.

 Motor and V/f Pattern Setup

The L7 inverter supports 2 motor settings (main motor and door motor, E2/E4-†† parameters) for V/f con-
trol, Open Loop Vector and Closed Loop Vector for IM. The active motor setup can be selected by a digital
input.
Closed Loop Vector Control for PM supports 1 motor setting (main motor, E5-†† parameters) only.

‹ Setting Motor Parameters for Induction Motors (Motor 1 and 2)

In order to achieve the maximum performance the V/f pattern and the motor data must be set correctly.
The number of motor parameters which can be set, depend on the selected control mode.
In the vector control methods the motor parameters can be set automatically by using the autotuning function
(refer to page 4-4, Autotuning).
However, if autotuning does not complete normally, the parameters must be set manually like described
below.

„Monitor Selection (o1-01)

Using parameter o1-01 the third monitor item that is displayed in drive mode can be selected. This function
has no effect on the LCD-operator (JVOP-160-OY).

„Monitor Display when the Power Supply is Turned ON (o1-02)

The parameter o1-02 selects the monitor item (U1-††), which is to be displayed in the first line on the Digi-
tal Operator when the power supply is turned ON.

Changing Frequency Reference and Display Units (o1-03)

Parameter o1-03 sets the display units of some frequency/speed related parameters on the Digital Operator.
The setting in o1-03 affects the display units of the following monitor items:
• U1-01 (Frequency Reference)
• U1-02 (Output Frequency)
• U1-05 (Motor Speed)

6-67
 • U1-20 (Output Frequency after Soft Start)
• d1-01 to d1-17 (Frequency references)

Display in Hz
Set o1-03 to “0” to change the display unit of the above mentioned parameters to Hz.

Display in%
Set o1-03 to “1” to change the display unit for the above mentioned parameters to % related to the maximal
frequency/speed set in parameter E1-04.

Display in rpm
Set o1-03 to the number of poles of the used motor to display the mentioned parameters in rpm.

Display in m/s
Set o1-03 to 3 to enable the display in m/s. The inverter uses the parameters S3-13 (traction sheave diameter),
S3-14 (roping ratio) and S3-15 (gear ratio) to calculate the m/s display. To achieve an accurate display value
these parameters must be set accurately.

„Changing the Units for Frequency Parameters Related to V/f settings (o1-04)
Using parameter o1-04 the unit of the frequency parameters for the V/f setting can be set. If o1-04 is set to 0
the unit is “Hz”. If o1-04 is set to 1 it is “rpm”. The parameter is available in Closed Loop Vector control only.

„Changing the Display Contrast (o1-05)

Using o1-05 the contrast of the LCD display on the digital operator can be raised or lowered. Lowering the
o1-05 value decreases the contrast and vice versa.
6 „Enable/Disable the LOCAL/REMOTE Key (o2-01)
Set o2-01 to 1 to enable the LOCAL/REMOTE Key on the Digital Operator.
If the key is enabled, the frequency reference source and the RUN command source can be switched over
between LOCAL (Operator) and REMOTE (b1-01/02 setting).

„Disabling the STOP Key (o2-02)

This parameter is used to set if the STOP key on the operator is active during remote control (b1-02 ≠ 0) or
not.
If o2-02 is set to 1, a STOP command from the operators STOP key is accepted. If o2-02 is set to 0 it is disre-
garded.

„Saving User Parameters (o2-03)

The Inverter parameter setting values can be saved as user-set parameter initial values by setting parameter
o2-03 to 1.
To initialize the inverter using the user-set initial values, set parameter A1-03 to 1110. To clear the user-set
initial values set o2-03 to 2.

„Changing the Inverter Capacity Setting (o2-04)

The inverter capacity setting can be set using parameter o2-04. Refer to page 5-67, Factory Settings Changing
with Inverter Capacity (o2-04) to see parameters that depend on this setting.
Normally it is not necessary to change this setting, unless the control card has been changed.

6-68
 „Setting the Frequency Reference using the UP and DOWN Keys without Using the
Enter Key (o2-05)
This function is active when frequency references are input from the Digital Operator. When o2-05 is set to 1,
the selected frequency reference can be incremented and decremented the UP and DOWN keys without using
the Enter key. The function work only if parameter b1-01 is set to 0.

„Operation Selection when the Digital Operator/LED Monitor is Disconnected (o2-06)

This function selects the operation when the digital operator/LED Monitor gets disconnected when a RUN
command is active.
If o2-06 is set to 0 the operation is continued.
If o2-06 is set to 1 the output is switched off and the motor coasts to stop. The fault contact is operated. When
the operator is reconnected an OPR (Operator disconnected) is shown.

„Cumulative Operation Time (o2-07 and o2-08)

The inverter has a function that counts the operation time of the inverter cumulatively.
Using parameter o2-07 the accumulated operation time can be changed, e.g. after a replacement of the control
board. If parameter o2-08 is set to 0, the inverter accumulates the time, whenever the power supply is switched
ON. If o2-08 is set to 1, the time when a RUN command is active is counted only. The factory setting is 0.

„Cooling Fan Operation Time (o2-10)

This function counts the operating time of the inverter mounted fan cumulatively.
Using parameter o2-10 the counter can be reset, e.g. when the fan has been replaced.

„Fault Trace Initialize (o2-12)

This function can be used to initialize the fault trace by setting parameter o2-12 to 1.
6
„“Number of Travels” counter Initialize (o2-15)
Using this parameter the lift operation counter monitor (U1-55) can be initialized.

‹ Copying Parameters (JVOP-160-OY only)

The following three digital operator functions can be used in order to copy/verify parameter settings:
• Store Inverter parameter set values in the Digital Operator by setting o3-01 to 1 (READ)
• Write parameter set values stored in the Digital Operator to the Inverter by setting o3-01 to 2 (COPY)
• Compare parameter set values stored in the Digital Operator with Inverter parameters settings by setting
o3-01 to 3 (VERIFY)
The data saved in the operator can be protected from overwriting by setting parameter o3-02 to 0. In this case
a READ command can not be executed. If it is nevertheless still done, “PrE” will be displayed at the operator.

PG Option Cards

To have a more precise speed control the inverter can be equipped with a PG option card for the connection of
a pulse generator. Three different PG cards can be used, the PG-B2, the PG-X2 and the PG-F2 card. Refer to
page 2-24, Option Card Models and Specifications to see details.

„Using PG Speed Control Card

There are three types of PG Speed Control Card that can be used in Closed Loop Vector control:
• PG-B2: A/B-phase pulse input, compatible with open collector outputs. 6
• PG-X2: A/B/Z-phase pulse input, compatible with line drivers (RS-422).

• PG-F2: Hiperfacey / EnDat encoder feedback.

For the mounting instructions, specifications and connection diagrams refer to page 2-24, Installing and Wir-
ing Option Cards.

If Open Loop Vector control for IM is used and a PG-B2/X2 card is installed, the speed detected by the
PG card is displayed in the monitor parameter U1-05. Therefore the PG constant has to be set in parame-
ter F1-01. The direction of the speed detection can be changed by parameter F1-05.
IMPORTANT
To change the U1-05 value to the internally calculated speed value remove the PG card.

„Setting Number of PG Pulses (F1-01)

Set the number of PG (Pulse Generator/Encoder) pulses in pulses per revolution.
If a PG-F2 card is installed, the encoder type must be set in parameter n8-35 before the PG constant is set. The
possible set values for F1-01 depend on the n8-35 setting. The following resolutions can be set:
• for Hiperfacey: 1024
• for EnDat: 512, 1024, 2048

6-75
 „Suit the PG Rotation Direction and Motor Rotation Direction (F1-05)
Parameter F1-05 can be used to change the encoder signal direction if it is wrong.
• If F1-05 is set to 0 the inverter expects channel A to lead 90° before channel B (Sin-channel leads 90°
before Cos-channel on PG-F2 card) if a forward command is applied (FWD means counterclockwise rota-
tion seen from the shaft side).
• If F1-05 is set to 1 the inverter expects channel B to lead 90° before channel B (Cos-channel leads 90°
before Sin-channel on PG-F2 card) if a forward command is applied.

If Closed Loop Vector Control for PM motors is used, an encoder offset autotuning must be per-
formed if parameter F1-05 is changed.
IMPORTANT

„Setting PG Pulse Monitor Output Division Ratio (F1-06)

This function is enabled only when a PG-B2 speed feedback card is used. Set the division ratio for the PG
pulse monitor output. The set value is expressed as n for the higher place digit, and m for the two lower place
digits. The dividing ratio is calculated as follows:
Dividing ratio = (1 + n)/m (Setting range) n: 0 or 1, m: 1 to 32
† ††
F1-06 = n m

The division ratio can be set within the following range: 1/32 ≤ F1-06 ≤ 1. For example, if the division ratio is
1/2 (set value 2), half of the number of pulses from the PG are output at the pulse monitor.

„Setting Number of Gear Teeth Between PG and Motor (F1-12 and F1-13)
6 If there are gears between the motor and PG, the gear ratio can be set using F1-12 and F1-13.
When the number of gear teeth has been set, the number of motor rotations within the Inverter is calculated
using the following formula.
No. of motor rotations (r/min.) = No. of input pulses from PG × 60 / F1-01 × F1-13 (No. of gear teeth on PG
side) / F1-12 (No. of gear teeth on motor side)

„Setting the Absolute Encoder Resolution (F1-21)

If a Hiperfacey encoder is used, the serial line resolution must be selected by parameter F1-21 according to
the encoder data sheet. The possible resolution setting depends on the encoder selection (n8-35=5):
• Hiperfacey: 0, 1 or 2 (16384, 32768, 8192)
• EnDat: 2 (fixed to 8192)

„Setting the Magnet Position Offset (F1-22)

Parameter F1-22 can be used to set the offset between the magnet and the encoder zero position. The value is
automatically set during the PM motor autotuning or encoder offset auto tuning (refer to page 4-8, PM Motor
Encoder Offset Tuning).

„Detecting PG Open Circuit During Run (F1-02 and F1-14)

Parameter F1-02 selects the stopping method when a PG disconnection is detected.
PG open (PGO) is detected only when the inverter is running at least with a frequency reference higher than
1% of the maximum output frequency or above the minimum frequency (E1-09) and the PG feedback signal is
missing for the time set in F1-14 or longer.
6
„Detecting Motor Overspeed (F1-03, F1-08 and F1-09)
An overspeed (OS) is detected when the motor speed continues to exceed the set frequency value in F1-08 for
a time longer than set in F1-09. After detecting an overspeed (OS), the Inverter stops according to the setting
in F1-03.

„Detecting a Speed Deviation between the Motor and Speed Reference (F1-04, F1-10
and F1-11)
A speed deviation fault is detected when the speed deviation (i.e., the difference between the speed reference
and the actual motor speed) is too large. Speed deviation (DEV) is detected only after a speed agreement
(speed reference and actual motor speed are within the setting range of L4-02) and if a speed deviation higher
than the set value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected,
the Inverter stops according to the setting in F1-04.

„Detecting a Wrong Rotation Direction DV3 (F1-18, Closed Loop Vector for PM only)
A DV3 fault indicates a wrong motor rotation direction. It is detected if
• the speed deviation is higher than 30% and
• the internal torque reference value and the acceleration have opposite signs
The fault is detected after the time F1-18 x 5 ms.

6-77
 „Detecting a Wrong Rotation Direction DV4 (F1-19, Closed Loop Vector for PM only)
A DV4 fault indicates a wrong motor rotation direction. It is detected if
• the reference direction and the motor rotation direction have opposite signs and
• the deviation is higher than the value of parameter F1-19 (set in encoder pulses).

‹ Machine Data Copy Function

If a Hiperfacey or an EnDat encoder is used, the motor and encoder data can be saved in the encoder memory
and can be read out later, e.g. if a motor has been replaced to an equal type or if the inverter is replaced.

„Saving Parameters Into the Encoder Memory

To save parameters in the encoder memory, the Encoder write protection must be off (F1-26 = 1) and the
parameter F1-25 has to be set to 1 (“ERED, INViENC WRITING” is displayed during the save process).
The display of F1-25 automatically returns to 0 when the operation is finished (“ERED, WRITE COM-
PLETE” is displayed). If any fault occurs the fault code will be displayed (refer to page 7-17, Machine Data
Copy Function Faults).
Parameters which had been stored in the encoder before will be overwritten.

„Read Parameters From the Encoder Memory

To read parameters form the encoder memory the parameter F1-25 must be set to 2. Before reading the param-
eters make sure, that the correct control mode and encoder type are selected in the parameters A1-02 and
n8-35. If parameter n8-35 has to be changed, cycle the power supply after changing it and set parameter F1-25
to 2 afterwards (“ECPY, ENCiINV COPIYING” is displayed during the read process). The display of F1-25
automatically returns to 0 when the operation is finished (“ECPY, COPY COMPLETE” is displayed). If any
fault occurs the fault code will be displayed (refer to page 7-17, Machine Data Copy Function Faults).

6-78
„Verify Saved Parameters
To compare the parameters stored in the inverter and encoder the parameter F1-23 must be set to 3 (“EVRFY,
DATA VERIFYING” is displayed during the verify process).
If the data are identically, the display will show “EVRFY, VERIFY COMPLETE”.
If the data do not match, “EVRFY, VERIFY ERROR” will be displayed.

In order to perform the WRITE/COPY function:

• The motor must not turn and the drive must be in baseblock condition
• for EnDat the OEM1 area1 of the EEPROM must be available (address 64 to 255)
IMPORTANT • for Hiperfacey the data field DF#0 must be available.
• A CPF03/24 must not be active.

 Rescue System

Using rescue operation the car can be moved to the next floor if the power supply fails. In this case the inverter
must be supplied by a UPS or a battery and the rescue operation must be enabled by a digital input (H1-†† =
85). The DC bus voltage during rescue operation has to be set in parameter L2-11. A light load detection func-
tion can be used to detect the light load direction for the car evacuation.

„Rescue Operation Speed

During rescue operation the speed is limited by the battery voltage using the following formula:
DC Bus Voltage L2-11 × Base frequency E1-04
• for the 200 V class: Rescue Operation Speed Limit = ---------------------------------------------------------------------------------------------------------------------
300 V × 2

DC Bus Voltage L2-11 × Base frequency E1-04

• for the 400 V class: Rescue Operation Speed Limit = ----------------------------------------------------------------------------------------------------------------------
600 V × 2
If the rescue speed reference (d1-15) is higher than the rescue operation speed limit, the output frequency is
automatically limited to the calculated limit. It prevents a voltage saturation and a possible motor stalling.

„Precautions
Because of the possibly low DC bus voltage during rescue operation, the heatsink cooling fans may not work.
A continuous operation under this condition can result in over heat faults and inverter damage.

6-82
„Torque Limits during Rescue Operation
Depending on the rescue system it might be useful to apply a torque limit. The torque limit for rescue opera-
tion can be set in parameter S3-11. It is active only if the rescue operation digital input is set an has no effect
to the normal operation.

„Light Load Direction Detection

If the light load detection function is enabled (S3-06 is set to 1), the inverter can detect the light load direction
for rescue operation. Therefore the elevator is driven with the light load detection speed (S3-10) sequentially
in forward and reverse direction for the time set in parameter S3-07. The current/torque is measured in each
direction and the values are compared to each other.
• If the detected light direction is forward, the inverter stops and restarts in the forward direction with the set
rescue operation speed. At the restart the light load detection status output (H2-††=45) and the light load
direction output (H2-††=44) are set.

currents value in both directions are compared.

„Working Principle
Whenever a fault occurs, the inverter output is cut and the brake is closed. A fault is output. When the auto-
matic fault reset is enabled, the fault is reset 2 seconds after the Up/Down signal has been removed. The
inverter can be restarted. This can be repeated for the number of times set in L5-02. The restart counter is reset
when the power supply is switched off.

„Fault Relay Operation

Parameter L5-02 can be used to enable or disable the fault relay (terminal MA-MB-MC) during the fault retry.
Even if the fault relay is deactivated during the retries (L5-02=0), it is operated after the number of retries set
in L5-01 has been reached.
• L5-02 = 1 enabled the fault relay.
• L5-02 = 0 disables the fault relay.

6-84
„Fault Restart Indication
When the fault retry function is used, the inverter tries to reset the fault every 5 ms. If a digital output is pro-
grammed for the “Restart enable” function (H2-††=1E), the output is set as long as the inverter tries to reset
the fault. After a successful fault reset the output is cleared.

„UV1 Fault Restart Selection

Using parameter L5-05 the auto reset method for a UV1 (DC bus under voltage) fault can be selected.
• If L5-05 = 0 the UV1 fault is treated like set in parameter L5-01, i.e. the inverter tries to reset UV1 for the
number of times set in L5-01 like described above.
• If L5-05 = 1 the UV1 fault is always automatically reset, regardless to the L5-01 setting.

08H Loop back test 8 8 8 8
10H Write multiple memory registers 11 41 8 8

Data
Configure consecutive data by combining the memory register address (test code for a loop back address) and
the data the register contains. The data length changes depending on the command details.

Error Check
Errors during communications are detected using CRC-16 (cyclic redundancy check, checksum method).
The result of the checksum calculation is stored in a data-word (16 bit), which starting value is FFFH. The
value of this word is manipulated using Exclusive OR- and SHIFT operations together with the data package
that should be sent (slave address, function code, data) and the fixed value A001H. At the end of the calcula-
tion the data-word contains the checksum value.
The checksum is calculated in the following way:
1. The starting value of the 16 Bit data-word, that is used for the calculation, has to be set to FFFFH.
2. An Exclusive OR operation has to be performed with the starting value and the slave address.
3. The result has to be shifted to the right until the overflow bit becomes 1.
4. When this bit becomes 1, an Exclusive OR operation with the result of step 3 and the fix value A001H has
to be performed.
5. After 8 shift operations (every time when the overflow bit becomes 1, an Exclusive OR like in step 4 has to 6
be done), perform an Exclusive OR operation with the result of the former operations and the next data
package (8 bit function code). Again the result of this operation has to be shifted 8 times and if needed it
has to be interconnected with the fix value A001H using an Exclusive OR operation.
6. The same steps have to be performed with the data, first with the higher byte and then with the lower byte
until all data are proceeded.
7. The result of these operations is the checksum. It consists of a high and a low byte.

6-87
 The following example clarifies the calculation method. It shows the calculation of a CRC-16 code with the
slave address 02H (0000 0010) and the function code 03H (0000 0011). The resulting CRC-16 code is D1H
for the lower and 40H for the higher byte. The example calculation in this example is not done completely
(normally data would follow the function code).

„MEMOBUS Message Example
An example of MEMOBUS command/response messages is given below.

Reading Inverter Memory Register Contents

The content of maximum 16 inverter memory registers can be read out at a time.
Among other things the command message must contain the start address of the first register to read out and
the quantity of registers. The response message will contain the content of the first and the consecutive num-
ber of registers that has been set for the quantity.
The contents of the memory register are separated into higher 8 bits and lower 8 bits.
The following tables show message examples when reading status signals, error details, data link status, and
frequency references from the slave 2 Inverter.

 Writing to Multiple Inverter Memory Registers
The writing of inverter memory registers works similar to the reading process, i.e. the address of the first reg-
ister that has to be written and the number of registers must be set in the command message.
The data registers which shall be written must be consecutive, starting from the specified address in the com-
mand message. The data order must be higher 8 bits, then lower 8 bits. The data must be in memory register
address order.
The following table shows an example of a message where a forward operation has been set with a frequency
reference of 60.0 Hz for the inverter with the slave address 01H.

‹ ENTER Command
When parameters are written in the Inverter from a PC/PLC using MEMOBUS communications, the parame-
ters are temporarily stored in the parameter data area of the Inverter. To enable these parameters in the param-
eter data area, an ENTER command must be used.
There are two types of ENTER commands:
• ENTER commands that enable parameter data in RAM only (changes will be lost after power loss)
• ENTER commands that write data into the EEPROM (non-volatile memory) of the Inverter and enable the
data in RAM at the same time.
Register Address. Contents
0900H Write parameter data to EEPROM, RAM is refreshed
0910H Parameter data are not written to EEPROM, but refreshed in RAM only.

An ENTER command is performed by writing 0 to register number 0900H or 0910H.

• The EEPROM can be written up to 100,000 times only. Do not frequently execute ENTER commands (0900H)
which write into the EEPROM.
• The ENTER command registers are write-only registers. Consequently, if these registers are read out, error code
IMPORTANT 02H is returned.
• An ENTER command is not required if reference or broadcast data are sent to the inverter.

 Protective and Diagnostic Functions

This section describes the fault and alarm functions of the Inverter. These functions include fault detection,
alarm detection, programming error detection and auto-tuning error detection.

‹ Fault Detection
When the Inverter detects a fault, the fault contact output is operated and the Inverter output is switched OFF
and the motor coasts to stop. (The stopping method can be selected for some faults.) A fault code is displayed
on the Digital Operator/LED Monitor.
The faults can be categorized in two groups:
• Faults that can be reset without cycling the power using an input or the reset key at the Digital Operator
(resetable faults)
• Faults that require to cycle the power (non-resetable faults)
When a fault has occurred refer to the following to identify the fault and to correct the causes.
To reset a fault it is necessary to remove the RUN signal and correct the fault reason. Otherwise a Reset is not
accepted or the Inverter trips with the same fault again.
The following tables shows a list of faults and corrective actions.

‹ Alarm Detection
Alarms are Inverter protection functions that indicate unusual conditions without switching off the drive and
operating the fault output contact. The alarm automatically disappears when its cause is eliminated.
During an alarm condition, the Digital Operator/LED Monitor alarm display flashes and an alarm output is
generated at the multi-function outputs (H2-01 to H2-03) if programmed.
When an alarm occurs, take appropriate countermeasures according to the table below.

 Troubleshooting

Due to parameter setting errors, faulty wiring etc., the Inverter and motor may not operate as expected when
the system is started. If that occurs, use this section as a reference and perform the appropriate countermea-
sures.
If a fault code is displayed, refer to page 7-2, Protective and Diagnostic Functions.

‹ If A Parameter Cannot Be Set

Use the following information if a parameter cannot be set.

„The display does not change when the Increment and Decrement keys are pressed.
The following causes are possible:

The Inverter is operating (drive mode).

There are some parameters that cannot be set during operation. Turn off the RUN command and then set the
parameters.

Passwords do not match. (Only when a password is set.)

If the parameter A1-04 (Password) and A1-05 (Password Setting) settings are different, the parameters for the
initialize mode cannot be changed. Enter the correct password in A1-04.
If the password got lost, check parameter A1-05 (Password Setting) by pressing the Shift/RESET key and the
MENU key simultaneously in the A1-04 display. Read the password and set it in parameter A1-04.

„OPE01 through OPE11 is displayed.

The set value for the parameter is wrong. Refer to Table 7.4 in this chapter and correct the settings.

„CPF00 or CPF01 is displayed.

7 This is a Digital Operator/LED Monitor communication error. The connection between the Digital Operator/
LED Monitor and the Inverter may be faulty. Remove the Digital Operator/LED Monitor and then re-install it.

7-18
‹ If the Motor Does Not Operate Properly
The following causes are possible:

„The motor does not operate when an external operation signal is input.
The frequency reference is 0.00 Hz or a no speed is selected by the digital inputs. Check the input signals and
the frequency reference settings.
Also make sure to set the Baseblock signal. The inverter does not accept any input if it is base blocked.

„The load is too heavy

Check the motor current. If it is at the limit of the inverter rated current the load might be too high. Check the
inverter size and the mechanical system. Check also if the brake is working or not to make sure, that the motor
is not running against the closed brake.

‹ If the Direction of the Motor Rotation is Reversed

If the motor rotates in the wrong direction, the motor output wiring may be incorrect.
The direction of the motor rotation can be reversed by switching two wires among U, V, and W. If an encoder
is used, the polarity has to be switched over as well. If the Inverter is operated in V/f mode parameter b1-04
can be used to change the rotation direction.

‹ If the Motor Stalls or Acceleration is Slow

„The torque limit has been reached.

When a torque limit has been set in parameters L7-01 to L7-04, the output torque will be limited according to
these settings. Therefore the motor may not develop enough torque to accelerate or the acceleration time might
be very long. 7
„The stall prevention level during acceleration is too low.
If the value set in L3-02 (Stall Prevention Level during Acceleration) is too low, the acceleration time will be
increased. Check that the set value is suitable and that the load is not too large for the motor.

„The stall prevention level during running is too low.

If the value set in L3-06 (Stall Prevention Level during Running) is too low, the motor speed and torque will
be limited. Check that the set value is suitable and that the load is not too large for the motor.

„Auto-tuning has not been performed for vector control

Vector control does not work properly, if auto-tuning has not been performed. Perform auto-tuning, or set the
motor parameters manually.

7-19
 ‹ If Motor Deceleration is Slow
The following causes are possible:

„The deceleration time is too long

The following causes are possible:

The deceleration time setting is too long.

Check the deceleration time setting (parameters C1-02, C1-04, C1-06, and C1-08).

‹ Motor torque is insufficient.

If the parameters are correct and there is no fault but the torque is insufficient, consider increasing the motor
and inverter capacity.

The torque limit has been reached.

When a torque limit is reached (L7-01 to L7-04), the motor torque will be limited. This can lengthen the decel-
eration time. Check the L7-†† parameters to be sure that the torque limit values are suitable.

‹ If the Motor Overheats

The following causes are possible:

„The load is too large.

If the motor load is too large and the torque exceeds the motor’s rated torque, the motor may overheat. Either
reduce the load or increase the acceleration/deceleration times. Also consider increasing the motor size.

7 „The ambient temperature is too high.

The motor rating is determined by a particular ambient operating temperature range. The motor will overheat
if it is run continuously at the rated torque in an environment where the maximum ambient operating tempera-
ture is exceeded. Lower the motor's ambient temperature to an acceptable value.

„Auto-tuning has not been performed for vector control

The Vector control performance may not be optimal, if auto-tuning has not been performed. Perform auto-tun-
ing, or set the motor parameters manually.
For induction motors alternatively the V/f control mode can be used.

7-20
‹ If Peripheral Devices are Influenced by the Starting or Running Inverter
The following solutions are possible:
• Change the Inverter's Carrier Frequency Selection (C6-02) to lower the carrier frequency. This will help to
reduce the amount of transistor switching noise.
• Install an Input Noise Filter at the Inverter's input power terminals.
• Install an Output Noise Filter at the Inverter's motor terminals.
• Use shielded motor cables or a conduit. Metal shields electrical noise.
• Check the grounding of the Inverter and motor.
• Separate main circuit wires from control circuit wires.

‹ If the Earth Leakage Breaker Operates When the Inverter is Running

The Inverter’s output is pulse modulated, i.e. the output voltage consists of high frequency pulses (PWM).
This high frequency signal causes a certain amount of leakage current which may cause the earth leakage
breaker to operate and cut off the power supply. Change to a ground fault interrupter with a high leakage
detection level (i.e., a sensitivity current of 200 mA or higher, with an operating time of 0.1 s or more), and
one, which incorporates high frequencies countermeasures (i.e., one designed for use with Inverters). Lower-
ing the Inverter's Carrier Frequency Selection (C6-02) can also help, since the leakage current increases with
the cable length.

‹ If There is Mechanical Oscillation

Use the following information when there is mechanical vibration:

„Oscillation and hunting occur with V/f control

The torque compensation parameter settings may be incorrect for the machine. Adjust parameters C4-01
(Torque Compensation Gain) and C4-02 (Torque Compensation Delay Time). Decrease C4-01 carefully in
7
steps of 0.05 and/or increase C4-02.
Furthermore the Slip Compensation Delay Time (C3-02) can be increased or decreased.

„Oscillation and hunting occur with Open Loop Vector control.

The torque compensation parameter settings may be incorrect for the machine. Adjust parameters C4-01
(Torque Compensation Gain), C4-02 (Torque Compensation Delay Time Parameter) and C3-02 (Slip Com-
pensation Delay Time) in order. Lower the gain parameters and raise the delay time parameters.
If auto-tuning has not been performed, proper performance may not be achieved for Vector Control. Perform
auto-tuning or set the motor parameters manually.

„Oscillation and hunting occur with Closed Loop Vector control for IM and PM
The gain adjustment may be insufficient. Adjust the speed control loop (Automatic Speed Regulator, ASR) by
changing the C5-†† parameters. If the oscillation points overlap with those of the machine and cannot be
eliminated, increase the ASR Delay Time, and then readjust the ASR gains.
If auto-tuning has not been performed, proper performance may not be achieved for Closed Loop Vector Con-
trol. Perform auto-tuning or set the motor parameters manually.

Maintenance and Inspection ...............................................8-2

 Maintenance and Inspection

‹ Periodic Inspection
Check the following items during periodic maintenance.
• The motor should not vibrate or make unusual noises.
• There should be no abnormal heat generation from the Inverter or motor.
• The ambient temperature should be within the Inverter’s specifications.
• The output current value shown in U1-03 should not be higher than the motor or the Inverter rated current
for extended period of time.
• The cooling fan in the Inverter should be operating normally.

Before attempting any maintenance checks, make sure that the three-phase power is disconnected. With power
removed from the unit, the DC bus capacitors will stay charged for several minutes. The charge LED in the
Inverter will light red until the DC bus voltage is below 10VDC. To ensure that the DC bus is completely dis-
charged, measure between the positive and negative bus with a DC voltmeter. Be sure not to touch terminals
immediately after the power has been turned off. Doing so can result in electric shock.

Altitude Input Voltage Output Current Max. Ambient Temperature
1000 m or less 100% 100% 100%
1000 to 2000 m 90% of standard spec. 90% of standard spec. 95% of standard spec.
2000 to 3000 m 80% of standard spec. 80% of standard spec. 90% of standard spec.

The maximum altitude is 3000m above sea level.

 Inverter Application Precautions

‹ Selection
Observe the following precautions when selecting an Inverter.

„Installing Reactors
A large peak current can flow in the power input circuit when the Inverter is connected to a large-capacity
power transformer (600 kVA or higher) or when switching a phase shifting capacitor. Excessive peak current
can destroy the converter section. To prevent this, install a DC or AC reactor to improve the power supply
power factor.
If a thyristor converter, such as a DC drive, is connected in the same power supply system, connect a DC or
AC reactor regardless of the power supply conditions shown in the following diagram.

Inverter capacity (kVA)

‹ Installation
Observe the following precautions when installing an Inverter.

„Installation in Enclosures
Install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, or
install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that
the temperature surrounding the Inverter does not exceed the allowable temperature. Do not install the Inverter
on wood or other combustible materials.

„Installation Direction
Mount the Inverter vertically to a wall or other vertical surface.

‹ Settings
Observe the following precautions when making settings for an Inverter.

„Upper Limits
The maximum output frequency can be set up to 120Hz. Setting the output frequency too high can damage the
10 machine. So pay attention to the mechanical system and observe required limits for the output frequency.

„DC Injection Braking

If the DC Injection Braking Current or the Braking Time are set too high the motor can overheat what can
damage the motor

10-2
 „Acceleration/Deceleration Times
The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load
torque, and the load's inertial moment (GD2/4). If the stall prevention functions are activated during accelera-
tion or deceleration, it might be necessary to increase the acceleration or deceleration time.
To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.

‹ Handling
Observe the following precautions during wiring or maintenance of an Inverter.

„Wiring Check
The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.
Check wiring for any mistakes before supplying power. Check all wiring and control sequences carefully.

„Magnetic Contactor Installation

If a magnetic contactor is installed in the power supply line, do not exceed one start per hour. Switching more
often can damage the inrush current prevention circuit.

„Maintenance and Inspections

After turning OFF the main circuit power supply it can take several minutes before the DC bus is discharged
completely. The CHARGE LED, indicating if the DC bus is charged, glows above a voltage of 10VDC.

10-3
 Motor Application Precautions

‹ Using the Inverter for an Existing Standard Motor

Observe the following precautions when using an Inverter for an existing standard motor.

„Low Speed Ranges

If a standard cooled motor is used at low speed the cooling effects are diminished. If the motor is used in con-
stant torque applications in low speed area the motor may overheat. If full torque is required at low speed con-
tinuously an externally cooled motor must be used.

„Installation Withstand Voltage

If the inverter is used with an input voltage of 440 V or higher and long motor cables, voltage spikes at the
motor terminals may occur which can damage the motor windings. Please ensure that the motor insulation
class is sufficient.

„Noise
The noise generated in the motor depends on the carrier frequency. The higher the setting, the less is the gen-
erated noise.

‹ Using the Inverter for Special Motors

Observe the following precautions when using a special motor.

„Pole-changing Motor
The rated input current of pole-changing motors differs from that of standard motors. Select an appropriate
Inverter according to the maximum current of the motor.

„Single-phase Motor
Do not use an Inverter for a single-phase motor. These motors are often equipped with capacitors Any capaci-
tor directly connected to the inverter output may damage the Inverter.
