Environmental statement
Control Techniques is committed to minimising the environmental impacts of its manufacturing operations and of its
products throughout their life cycle. To this end, we operate an Environmental Management System (EMS) which is
certified to the International Standard ISO 14001. Further information on the EMS, our Environmental Policy and other
relevant information is available on request, or can be found at www.greendrives.com.
The electronic variable-speed drives manufactured by Control Techniques have the potential to save energy and
(through increased machine/process efficiency) reduce raw material consumption and scrap throughout their long
working lifetime. In typical applications, these positive environmental effects far outweigh the negative impacts of product
manufacture and end-of-life disposal.
Nevertheless, when the products eventually reach the end of their useful life, they can very easily be dismantled into their
major component parts for efficient recycling. Many parts snap together and can be separated without the use of tools,
while other parts are secured with conventional screws. Virtually all parts of the product are suitable for recycling.
Product packaging is of good quality and can be re-used. Large products are packed in wooden crates, while smaller
products come in strong cardboard cartons which themselves have a high recycled fibre content. If not re-used, these
containers can be recycled. Polythene, used on the protective film and bags for wrapping product, can be recycled in the
same way. Control Techniques' packaging strategy favours easily-recyclable materials of low environmental impact, and
regular reviews identify opportunities for improvement.
When preparing to recycle or dispose of any product or packaging, please observe local legislation and best practice.

1.3 System design and safety of

personnel
The drive is intended as a component for professional incorporation into
complete equipment or a system. If installed incorrectly, the drive may
present a safety hazard.
The drive uses high voltages and currents, carries a high level of stored
electrical energy, and is used to control equipment which can cause
injury.
Close attention is required to the electrical installation and the system
design to avoid hazards either in normal operation or in the event of
equipment malfunction. System design, installation, commissioning and
maintenance must be carried out by personnel who have the necessary
training and experience. They must read this safety information and this
guide carefully.
The STOP and SECURE DISABLE functions of the drive do not isolate
dangerous voltages from the output of the drive or from any external
option unit. The supply must be disconnected by an approved electrical
isolation device before gaining access to the electrical connections.
None of the drive functions must be used to ensure safety of
personnel, i.e. they must not be used for safety-related functions.
Careful consideration must be given to the functions of the drive which
might result in a hazard, either through their intended behaviour or
through incorrect operation due to a fault. In any application where a
malfunction of the drive or its control system could lead to or allow
damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk - for example, an
over-speed protection device in case of failure of the speed control, or a
fail-safe mechanical brake in case of loss of motor braking.

1.4 Environmental limits

Instructions in this guide regarding transport, storage, installation and
use of the drive must be complied with, including the specified
environmental limits. Drives must not be subjected to excessive physical
force.

1.5 Compliance with regulations

The installer is responsible for complying with all relevant regulations,
such as national wiring regulations, accident prevention regulations and
electromagnetic compatibility (EMC) regulations. Particular attention
must be given to the cross-sectional areas of conductors, the selection

2.1 Regen operation

For use as a regenerative front end for four quadrant operation.
Regen operation allows bi-directional power flow to and from the AC
supply. This provides far greater efficiency levels in applications which
would otherwise dissipate large amounts of energy in the form of heat in
a braking resistor.
The harmonic content of the input current is negligible due to the
sinusoidal nature of the waveform when compared to a conventional
bridge rectifier or thyristor front end.

2.2 Advantages of Unidrive SP operating

in regen mode
The main advantages of an AC Regen system are:
• Energy saving
• The input current waveform is sinusoidal
• The input current has a near unity power factor
• Power factor correction can be implemented using Pr 4.08
• The output voltage for the motor can be higher than the available AC
mains supply.
• The Regen drive will synchronise to any frequency between 30 and
100Hz, provided the supply voltage is within the supply requirements
(operating frequency range of 48Hz to 65Hz)
• Under conditions of AC mains instability, a Unidrive SP Regen
system can continue to operate down to approximately 75Vac (200V
product) 150Vac (400V product) 225Vac (575V and 690V product)
supply voltage without any effect on the DC bus voltage and hence
on the operation of the motoring drives (increased current will be
taken from the AC supply during this condition to compensate up to
the current limit of the Regen drive)

2.8 Regen drive system types

2.8.1 Single Regen, single motoring system
Figure 2-2 shows a typical layout for a standard regen system consisting of a single Regen drive and single motoring drive. In this configuration the
Regen drive is supplying the motoring drive and passing the regenerative energy back to the mains supply.
NOTE
The power up connections to L1, L2, L3 of the Regen drive are only made during power-up. Once both drives are powered up, this is switched out
and the main regen supply switched in. The auxiliary on the charging circuit to the Regen drive’s L1, L2, L3 connections for power up must be closed
(charging supply removed) before the Regen drive can be enabled.

2.8.3 Multiple Regen, multiple motoring system

Figure 2-5 shows a multiple regen drive system with multiple motoring drives. For this configuration the regen drives are sized to the total power
requirement of all motoring drives.
NOTE
For the multiple regen and multiple motoring drives arrangement there are two possible options for the required start-up circuit. This can either consist
of a Unidrive SPMC rectifier module (for example an SPMC 1402 is capable of charging a maximum DC Bus capacitance of 66mF) or an external
charging resistor as detailed in Chapter 4 System design on page 30.
Special care should be taken when designing a multiple regen and multiple motoring drive system ensuring that all the required fusing is in place on
both the common DC Bus connections and the AC supply to all regen drives.

The inductors are standard three phase inductors (rated at Unidrive SP
Regen drive rated current). They carry only 50/60Hz current with a SPMD1402
negligible amount of high frequency current. The above switching SP6402
frequency filter inductors are calculated at 4% of the regen drives rating SPMA1402 SPMA1402
using the following formula. A tolerance can be applied to the calculated SPMD1402 1665-8774 77 26

3.10.3 Varistors
AC line voltage transients can typically be caused by the switching of large items of plant or by lightning strikes on another part of the supply system.
If these transients are not suppressed they can cause damage to the insulation of the regen input inductors, or to the Regen drive electronics.
The following varistors should therefore be fitted as shown in section 4.2 Power connections .

Drive losses
2 x Unidrive SP 2403 = 626W
When the motoring drive is supplying rated current to the motor, the
Regen drive needs to provide 13.5kW, plus drive losses = 14.126kW.
The Regen drive can supply 15.9kW at rated current, which is ample, in
this case.
Conversely, in some cases, a Regen drive of the same rating as the
motoring drive, may not be able to supply enough power, as the
following example shows:
Example
In the case of a 96A (Heavy Duty), SP4403 operating in regen mode,
and a SP4403 driving a 75kW, 400V, 0.95pf motor:
If the motoring drive is supplying 175% maximum current, and the
Regen drive has its 380V supply at the lower limits of -10% (342Vac),
then, with a regen current limit of 150%:

The Regen drive maximum available power is:

3 × 150% × Rated current × Supply voltage
= 1.73 x 1.5 x 96 x 342
= 85.1kW
The motoring drives maximum. power is:
3 × 175% × Rated current × Motor voltage × Power factor
= 1.73 x 1.75 x 96 x 400 x 0.95
= 110.4kW
Drive losses
2 x Unidrive SP 4403 = 1.952kW
The Regen drive is also required to supply the Regen and motoring drive
losses in this example 1.952kW which brings the total power

See Chapter 10 Technical data on page 183 for fuse rating information.
Unidrive SPMC
For a regen system, the SPMC can be used to charge the common DC
bus when the power is first applied, however this will once the regen
system is powered up no longer be required.
The Unidrive SPMC must be supplied with 24Vdc to feed both the fans
and control circuits. This 24Vdc can also be used as a means of starting
and stopping the SPMC rectifier as the SPMC will only fire its thyristors
when the 24Vdc is present.
Fitting a 5A relay interlocked (or a normally closed auxiliary contact) to
the Regen drives main contactor to switch the 24V supply will allow the
SPMC to charge the common DC bus then be disabled (optional).
The total amount of capacitance on the common DC bus that the SPMC
can drive is limited due to the inrush current (produced during power up
and during brownouts).
See the following Table for the capacitance limit.
Unidrive SP drive DC bus capacitance levels are available in Table 11-
1 on page 203.

4.6 Exceeding maximum cable length

If the total maximum length specified is exceeded, the increased
circulating currents caused by the extra cable capacitance will have an
effect on the other parts of the system. This will necessitate additional
components to be added to the standard arrangement.
4.6.1 Regen inductor
If the maximum cable length specified is exceeded this will introduce
increased heating of the regen inductor. To overcome the additional
heating forced cooling should be introduced into the system as specified
in the following table.
The forced cooling should be positioned as shown below to provide the
specified airflow directly onto the regen inductor windings.

4.6.3 EMC filter
When an EMC filter is used the capacitors to ground carry common
mode current.
When the maximum cable length without additional ventilation specified
is exceeded, extra circulating currents can result in heating and
saturation of the EMC filter. To prevent this, some capacitance line to
ground should be provided as an additional path for this current, as
shown in Figure 4-8. See also section 4.4.3 Motor connection on
page 41.

also be used to protect the EMC filter from overload.
CAUTION

4.6.4 Line to ground capacitors for multi-drive

systems
Selection of line to ground capacitors for regen systems with long
cables.
In order to select the appropriate capacitors, the rms value of the current
line to ground, the AC supply voltage and minimum capacitance values
are required.
A minimum capacitance value of 1µF per phase should be used with the
final capacitance value being determined by the level of current line to
ground. In practice, to carry the required level of current the capacitor
will generally have a higher capacitive value. The current rating of the
capacitors should be at a high frequency such as 100kHz at the relevant
supply voltage. Polypropylene type capacitors (x type) are the most
suitable because of their low loss at high frequency.
The rms value of the current can be estimated from the following
formula:

I RMS = 2.8 × 10
–4
× K × V DC Σ lfs
Where:
k is 1 for simple rectifier-input systems, √2 for regen systems
VDC is DC bus voltage
∑lfs is the sum of the products of motor cable lengths and switching
frequencies of all drives in the system, including in the case of
regenerative systems the Regen drive with the total DC cable length
l is total cable length in m
fs is switching frequency in kHz
If all drives operate at 3kHz, the expression can be simplified to:
IRMS = 4.85 x 10-4 x K x VDC x √l

Example
A regen system operating with a supply of 400Vac giving a DC bus
voltage of 620V at 3kHz switching frequency and a cable length of 1km
(motors + DC) has an IRMSof:

IRMS = 4.85 x 10-4 x K x VDC x √l

IRMS = 4.85 x 10-4 x √2 x 620 x √1.000
IRMS= 13.4A

Cautions and warnings

In case of dents of more than 2 mm depth or any other mechanical
damage, capacitors must not be used at all.
To ensure the full functionality of the overpressure disconnector, elastic
elements must not be hindered and a minimum space of 5 cm has to be
kept above each capacitor.
Protection should be provided to prevent over current and short circuit.

Discharging
Capacitors must be discharged to a maximum of 10% of rated voltage
before they are switched in again.
The capacitor must be discharged to 75 V or less within 3 minutes.
There must be not any switch, fuse or any other disconnecting device in
the circuit between the power capacitor and the discharging device.

Over current and short circuit protection

Use HRC fuses or MCCBs for short circuit protection. Short circuit
protection and connecting cables should be selected so that 1.5 times
the rated capacitor current can be permanently handled.
HRC fuses do not protect a capacitor against overload - they are only for
short circuit protection.
The HRC fuse rating should be 1.6 to 1.8 times rated capacitor current.

5.6 Cubicle design and drive ambient

temperature
Drive derating is required for operation in high ambient temperatures
(derating information is provided in the Unidrive SP User Guide).
Totally enclosing or through panel mounting the drive in either a sealed
cabinet (no airflow) or in a well ventilated cabinet makes a significant
difference on drive cooling.
The chosen method affects the ambient temperature value (Trate) which
should be used for any necessary derating to ensure sufficient cooling
for the whole of the drive.
The ambient temperature for the four different combinations is defined
below:
1. Totally enclosed with no air flow (<2 m/s) over the drive
Trate = Tint + 5°C
2. Totally enclosed with air flow (>2 m/s) over the drive
Trate = Tint
3. Through panel mounted with no airflow (<2 m/s) over the drive
Trate = the greater of Text +5°C, or Tint
4. Through panel mounted with air flow (>2 m/s) over the drive
Trate = the greater of Text or Tint
Where:
Text = Temperature outside the cabinet
Tint = Temperature inside the cabinet
Trate = Temperature used to select current rating from tables in
Chapter 10 Technical data on page 183.

Regen inductors can produce significant losses with a normal

operating temperature in the region of 150°C dependant
upon the ambient temperature. Location of the regen
inductors should be considered to prevent damage to heat
CAUTION sensitive components or create a fire risk.

6 Electrical Installation
Electric shock risk
The voltages present in the following locations can cause
severe electric shock and may be lethal:

WARNING
• AC supply cables and connections
• DC connections
• Output cables and connections
• Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single
insulated and must not be touched.

Isolation device
The AC supply must be disconnected from the drive using
an approved isolation device before any cover is removed
WARNING
from the drive or before any servicing work is performed.

Stored charge
The drive contains capacitors that remain charged to a
potentially lethal voltage after the AC supply has been
disconnected. If the drive has been energised, the AC
WARNING supply must be isolated at least ten minutes before work
may continue.
Normally, the capacitors are discharged by an internal
resistor. Under certain, unusual fault conditions, it is possible
that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output
terminals. If the drive has failed in a manner that causes the
display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult Control
Techniques or their authorised distributor.

Equipment supplied by plug and socket

Special attention must be given if the drive is installed in
equipment which is connected to the AC supply by a plug
and socket. The AC supply terminals of the drive are
WARNING connected to the internal capacitors through rectifier diodes
which are not intended to give safety isolation. If the plug
terminals can be touched when the plug is disconnected
from the socket, a means of automatically isolating the plug
from the drive must be used (e.g. a latching relay).

6.1.2 Ground connections Figure 6-8 Unidrive SP size 2 ground connections

Size 1
On a Unidrive SP size 1, the supply and motor ground connections are
made using the studs located either side of the drive near the plug-in
power connector. Refer to Figure 6-1 on page 66.
Size 2
On a Unidrive SP size 2, the supply and motor ground connections are
made using the grounding bridge that locates at the bottom of the drive.
See Figure 6-8 for details.
Size 3
On a Unidrive SP size 3, the supply and motor ground connections are
made using an M6 nut and bolt that locates in the fork protruding from
the heatsink between the AC supply and motor output terminals. See
Figure 6-9 for details.
Size 4, 5, 6, SPMA and SPMD
On a Unidrive SP size 4, 5, 6, SPMA and SPMD the supply and motor
ground connections are made using an M10 bolt at the top (supply) and
bottom (motor) of the drive. See Figure 6-10.
The supply ground and motor ground connections to the drive are
connected internally by a copper conductor with a cross-sectional area
given below:
Size 4: 19.2mm2 (0.03in2, or slightly bigger than 6 AWG)
Size 5: 60mm2 (0.09in2, or slightly bigger than 1 AWG)
Size 6: 75mm2 (0.12in2, or slightly bigger than 2/0 AWG)
SPMA: 75mm2 (0.12in2, or slightly bigger than 2/0 AWG)
Figure 6-9 Unidrive SP size 3 ground connections
SPMD: 120mm2 (0.18in2, or slightly bigger than 2 AWG)
This connection is sufficient to provide the ground (equipotential
bonding) connection for the motor circuit under the following conditions:
Table 6-1 Cables and standards
Standard Conditions
Supply phase conductors having cross-sectional area
not exceeding:
Size 4: 38.4mm2

EN 60204-1
Size 6: 150mm2
SPMA: 150mm2
SPMD: 240mm2
If the necessary conditions are not met, an additional ground connection
must be provided to link the motor circuit ground and the supply ground.

The ground loop impedance must conform to the

requirements of local safety regulations.
The drive must be grounded by a connection capable of

NOTE N
Supply Drives rated for supply voltages up to 690V are suitable for use with
ground supply types with neutral or centre grounding i.e. TN-S, TN-C-S, TT
The following supplies are not permitted with Unidrive SP Regen
1. Corner grounded supplies (grounded Delta)
2. Ungrounded supplies (IT) > 575V
6.2.1 Supply types
Drives are suitable for use on supplies of installation category III and
lower, according to IEC60664-1. This means they may be connected
permanently to the supply at its origin in a building, but for outdoor
installation additional over-voltage suppression (transient voltage surge
suppression) must be provided to reduce category IV to category III.
6.2.2 Dedicated supplies
The nature of the mains supply has an important effect on the EMC
arrangements. For a dedicated supply, i.e. one which has no other
electrical equipment fed from the secondary of its distribution
transformer, normally neither an EMC filter or a switching frequency filter
are required. Refer to section 4.3.1 Omitting the switching frequency
filter on page 40.

Motor
6.2.3 Other supplies
ground Wherever other equipment shares the same low voltage supply, i.e.
400Vac, careful consideration must be given to the likely need for both
switching frequency and EMC filters, as explained in section

emission for advice on switching frequency emission.

6.2.5 Supply harmonics

When operated from a balanced sinusoidal three-phase supply, the
regenerative Unidrive SP generates minimal harmonic current.
Imbalance between phase voltages will cause the drive to generate
some harmonic current. Existing voltage harmonics on the power
system will cause some harmonic current to flow from the supply into the
drive. Note that this latter effect is not an emission, but it may be difficult
to distinguish between incoming and outgoing harmonic current in a site
measurement unless accurate phase angle data is available for the
harmonics. No general rule can be given for these effects, but the
generated harmonic current levels will always be small compared with
those caused by a conventional drive with rectifier input.

6.3 Cable and fuse ratings

The input current is affected by the supply voltage and impedance.
Typical input current
The values of typical input current are given to aid calculations for power
flow and power loss.
The values of typical input current are stated for a balanced supply.
Maximum continuous input current
The values of maximum continuous input current are given to aid the
selection of cables and fuses. These values are stated for the worst case
condition with the unusual combination of stiff supply with bad balance.
The value stated for the maximum continuous input current would only
be seen in one of the input phases. The current in the other two phases
would be significantly lower.
The values of maximum input current are stated for a supply with a 2%
negative phase-sequence imbalance and rated at the maximum supply

6.5 External EMC filter

In order to provide our customers with a degree of flexibility, external
EMC filters have been sourced from two manufacturers: Schaffner and
Epcos. The external EMC Filter ratings and dimensions information are
available in the Unidrive SP User Guide.
For currents exceeding 300A up to 2500A, suitable filters are also
available from both Epcos and Schaffner as detailed.
Loosen screws (1). Remove EMC filter in the direction shown (2).
• Epcos B84143-B250-5xx (range up to 2500A)
• Schaffner FN3359-300-99 (range up to 2400A)
These filters may not give strict conformity with EN6000-6-4 but in
conjunction with EMC installation guidelines they will reduce emissions
to sufficiently low levels to minimise the risk of disturbance.
When a EMC filter is used, the switching frequency filter
detailed must also be used. Failure to observe this may result
in the EMC filter becoming ineffective and being damaged.
Refer to section 6.4 EMC (Electromagnetic compatibility) on
CAUTION page 77.

When an EMC filter is used, a permanent fixed ground

connection must be provided which does not pass through a
connector or flexible power cord. This includes the internal
WARNING
EMC filter.

The installer of the drive is responsible for ensuring

compliance with the EMC regulations that apply where the
drive is to be used.

6.5.12 Conducted RF emission

Radio frequency emission in the frequency range from 150kHz to
30MHz is mainly conducted out of the equipment through electrical
wiring. It is essential for compliance with all emission standards, except
for IEC61800-3 second environment, that the recommended EMC filter
and a shielded (screened) motor cable are used. Most types of cable
can be used provided it has an overall screen. For example, the screen
formed by the armouring of steel wired armoured cable is acceptable.
The capacitance of the cable forms a load on the drive and should be
kept to a minimum. The same considerations apply to any cables
connecting the DC bus between drives, except that short direct wiring
within the same enclosure need not be screened.

When an EMC filter is used the switching frequency filter

discussed above must also be used. Failure to observe this
may result in the EMC filter becoming ineffective and being

When used with the recommended filters, the Regen drive system
complies with the requirements for conducted emission in the following

7.4.1 Motoring drive enable
When the Regen drive has been successfully synchronised, Pr 3.09 on
the Regen drive will become active and digital output F1 on terminal 24
also becomes active allowing the motoring drive(s) to be enabled. If the
Regen drive trips or attempts to re-synchronise to the supply, Pr 3.09
becomes zero and the enable signal for the motoring drive(s) is
removed.
The setting of certain parameters in the motoring drive must be given
special consideration when used in a regen system.
7.4.2 Ramp Mode - Pr 2.04 (Pr 0.15)
When a motoring drive is used in a regen system, the ramp mode should
be set to FAST. The default setting of standard control will result in
incorrect operation.
7.4.3 Voltage Control Mode - Open loop only Pr 5.14
(Pr 0.07)
The default setting of UR_I does not function correctly in the motoring
drive when used in a regen system. When the system is powered up, the
motoring drive is disabled while the Regen drive synchronises to the AC
supply. The resultant delay before the motoring drive is enabled means
that the stator resistance test cannot be completed. When open loop
vector operation is required the voltage mode should be set to UR_S.
7.4.4 AC Supply Loss Mode - Pr 6.03
The motoring drive will not operate correctly if the AC supply loss mode
is set to STOP. If the AC supply is lost, the Regen drive disables the
motoring drive and prevents a controlled stop from being completed.

8 Optimisation
The following section covers optimisation of the regen system which can
be carried out by the user.

Feature Detail
Power feed-forward can be used to reduce fast transient DC Bus voltage effects produced by transient load conditions on
Power feed-forward motoring drives mainly in Dynamic applications
where spurious over-voltage and/or over-current trips are experienced.
The voltage controller gain can be implemented to overcome instability in the DC voltage on the common DC Bus in the
following conditions,
• A brake resistor replacement system where the ratio between regen brake drive and motoring drive(s) DC Bus
capacitance is large
Voltage controller gain
• With multiple motoring drive(s) where the ratio between the regen drive(s) and motor drive(s) DC Bus capacitance is
large.
Ensure the voltage controller gain is not increased to high as this can also introduce excessive ripple and instability on
the DC Bus.
The current loop gains can be optimised to overcome spurious over-current trips during either synchronisation to the
power supply, or during operation.
Current loop gains
The default gain settings are sufficient for most applications however these can be modified with the proportional (Kp)
being the most critical for stability.
This does not optimize the regen system but improves the power factor of the supply that is connected to the regen
system.
• Will introduce cost saving (electricity bill), compensate for inductive loads on the same supply, and overcome voltage
Power factor correction drops due to “soft supplies”.
• A separate power factor correction unit may not be required.
• The symmetrical current limit must be below its maximum in order for power factor correction to work (therefore may
be limited due to regen drive size).

The Regen drive uses a DC bus voltage controller with inner current Only one analogue output from the motoring drive and one analogue input

8.5 Current trimming

From software V1.10 for Unidrive SP the current trimming can be user
configurable. The default setting for the current trimming in software
V1.10 is as with previous software versions.
The current trimming mode parameter (Pr 3.11) defines the strategy
used for trimming the current feedback when operating in regen mode
with Unidrive SP.
The two modes that can be selected are as detailed following
Mode 1 - At power up only [Pr 3.11 = 0]
Current trimming is only carried out once after power-up, as
previously available (pre software V1.10) with Unidrive SP Regen.
Mode 2 - At power up and on each enable [Pr 3.11 = 1]
Current trimming is carried out as previously available, once after
power-up, and now in addition it is also carried out before the drive
runs each time it is enabled (software V1.10 onwards) with Unidrive
SP Regen.

9 Parameters
9.1 Parameter ranges and variable maximums:
The two values provided define the minimum and maximum values for the given parameter. In some cases the parameter range is variable and
dependant on either:
• other parameters
• the drive rating
• drive mode
• or a combination of these
The values given in Table 9-1 are the variable maximums used in the drive.
Table 9-1 Definition of parameter ranges & variable maximums

Maximum Definition
Maximum motor rated current
RATED_CURRENT_MAX = 1.36 x Rated drive current.
RATED_CURRENT_MAX
The rated current can be increased above the Regen drive rated current up to a level not exceeding 1.36 x
[9999.99A]
Regen drive rated current. (Maximum rated current is the maximum Normal Duty current rating.)
The actual level varies from one drive size to another, refer to Table 3-2 on page 14.
Maximum drive current
DRIVE_CURRENT_MAX
The maximum drive current is the current at the over current trip level and is given by:
[9999.99A]
DRIVE_CURRENT_MAX = Regen drive rated current / 0.45
Unidrive SP in regen mode operates in a reference frame that is aligned to the voltage at the drive terminals. As
the phase shift across the input inductors is small, the reference frame is approximately aligned with the supply
voltage. The maximum normal operating current is controlled by the current limits.
DRIVE_CURRENT_MAX is used in calculating the maximum of some parameters and is fixed at 1.75 x rated
drive current. The drive can operate up to this level under normal conditions.
CURRENT_LIMIT_MAX is used as the maximum for some parameters such as the user current limits. The
maximum current limit is defined as follows (with a maximum of 1000%):
Maximum current
CURRENT_LIMIT_MAX = ⎛ -------------------------------------------------------------------------⎞ × 100%
⎝ Regen drive rated current⎠

Where:
The Regen drive rated current is give by Pr 5.07
CURRENT_LIMIT_MAX
The maximum current is either 1.75 x rated drive current when the rated current set by Pr 5.07 is ≤maximum
[1000.0%]
Heavy Duty current rating, otherwise it is 1.1 x maximum rated current.
The rated active and rated magnetising currents are calculated from regen mode rated current (Pr 5.07) as:
Rated active current = Regen mode rated current
Rated magnetising current = 0
In this mode, the drive only requires the regen mode rated current to set the maximum current limit correctly
and scale the current limits, and so no user autotuning is required to set these accurately.
It is possible to set a level of reactive current with Pr 4.08 in regen mode. This parameter has a limit defined as
REGEN_REACTIVE_MAX that is provided to limit the total current to DRIVE_CURRENT_MAX.

[9999.99kW]
Software V01.07.01 and earlier: POWER_MAX = √3 x AC_VOLTAGE_MAX x RATED_CURRENT x 1.75
Software V01.08.00 and later: POWER_MAX = √3 x AC_VOLTAGE_MAX x DRIVE_CURRENT_MAX

The values given in square brackets indicate the absolute maximum value allowed for the variable maximum.

In regen mode the drive assumes the mains is lost, it does not close the input, and does not attempt synchronisation if the DC bus voltage is below
the levels given in the table below.
If the unit is synchronised and the DC bus voltage falls below this level the unit is disabled and the Regen drive main contactor is opened.
The Regen drive also monitors the voltage at it's AC terminals (U, V and W) for mains loss and if this falls below the levels given in the table the unit

value given is only approximate, but will give an indication as whether the input inductance is correct for the sinusoidal rectifier unit size. The

The Regen drive will attempt to hold the DC bus at the level specified by this parameter. The DC bus voltage must always be higher than the peak of

The gains of the voltage and current controllers affect the stability of the regen unit control system and incorrect gain settings can result in over-
voltage or over-current trips. In many applications the default gains given for the current controllers (Pr 4.13 and Pr 4.14) will be suitable, however, it
may be necessary for the user to change these if the inductance or resistance of the supply plus the regen inductors varies significantly from the
expected values.
Setting the current controller gains
The most critical parameter for stability is the current controller proportional gain (Pr 4.13). The required value for this is dependent on the Regen unit
input inductance. If the inductance of the supply is a significant proportion of the recommended regen inductor (i.e. 60/IDR mH per phase, where IDR
is equivalent to Kc), then the proportional gain may need to be increased. The supply inductance is likely to be negligible compared to the regen
inductor value with small drives, but is likely to be significant with larger drives.
The proportional gain Pr 4.13 should be adjusted as described below using the total inductance per phase. The current controller integral gain Pr 4.14
is not so critical, and in a majority of cases the default value is suitable. However, if it is necessary to adjust this parameter it should be set up as
described below using the supply resistance for one phase.
The proportional gain Kp (Pr 4.13) is the most critical value in controlling the performance of the current controllers. The value can be set by the user
so that
Kp = (L / T) x (Ifs / Vfs) x (256 / 5)
Where:
T is the sample time of the current controllers. The drive compensates for any change of sample time, and so it should be assumed that the sample
time is equivalent to the lowest sample rate of 167µs.
L is the total inductance per phase
Ifs is the peak full scale current feedback = Kc x √2 / 0.45. Where Kc is the current scaling for each size of drive.
Vfs is the maximum DC link voltage.

Therefore:
Kp = (L / 167µs) x (Kc x √2 / 0.45 / Vfs) x (256 / 5) = K x L x Kc
Where:
K = [√2 / (0.45 x Vfs x 167µs)] x (256 / 5)

There is one value of the scaling factor K for each drive voltage rating as shown in the table below.

Drive voltage rating Vfs K

200V 415V 2322
400V 830V 1161
575V 990V 973
690V 1190V 809

The integral gain Ki (Pr 4.14) is less critical and should be set so that

Ki = Kp x 256 x T / τm
where
τm is the time constant (L / R).
R is the resistance of the supply for one phase.

Therefore
Ki = (K x L x Kc) x 256 x 167µs x R / L = 0.0427 x K x R x Kc

The above equations give the gain values that should give the best response at all switching frequencies with minimal overshoot. If required the gains
can be adjusted to improve performance as follows:
1. The integral gain (Ki) can be used to improve the performance of the current controllers by reducing the effects of inverter non-linearity. These
effects become more significant with higher switching frequency. These effects will more significant for drives with higher current ratings and
higher voltage ratings. If Ki is increased by a factor of 4 it is possible to get up to 10% overshoot in response to a step change of current
reference. For high performance applications, it is recommended that Ki is increased by a factor of 4 from the auto-tuned values. As the inverter
non-linearity is worse with higher switching frequencies it is may be necessary to increase Ki by a factor of 8 for operation with 16kHz switching
frequency.
2. It is possible to increase the proportional gain (Kp) to reduce the response time of the current controllers. If Kp is increased by a factor of 1.5 then
the response to a step change of reference will give 12.5% overshoot. It is recommended that Ki is increased in preference to Kp.
Setting the voltage controller gain
Even when the gains are set correctly there will be a transient change of DC Bus voltage when there is a change in the load on any drive connected
to the Regen unit. This can be reduced substantially by using an analogue input for power feed forward compensation (see Pr 3.10). The following
discussion relates to a system without power feed-forward compensation.
If the power flow from the supply is increased (i.e. more power is taken from the supply or less power is fed back into the supply) the DC Bus voltage
will fall, but the minimum level will be limited to just below the peak rectified level of the supply provided the maximum rating of the unit is not
exceeded. If the power flow from the supply is reduced (i.e. less power is taken from the supply or more power is fed back into the supply) the DC Bus
voltage will rise. During a rapid transient the bus will rise and then fall as shown below.

The example shown is for a very rapid load change where the torque reference of the motor drive has been changed instantly from one value to
another. The proportional gain of the voltage controller defines the voltage transient because the integral term is too slow to have an effect. (In
applications where the motor drive is operating under speed control, the speed controller may only require a limited rate of change of torque demand,
and so the transient voltage may be less than covered in the discussion below.) If the set point voltage (Pr 3.05) plus the transient rise exceed the
over-voltage trip level the Regen unit will trip.
When a 400V motor is operated above base speed from a drive in vector mode, fed from the Regen unit with the same rating supplying a DC voltage
of 700V, and an instantaneous change of torque is demanded (i.e. -100% to +100%) the peak of the voltage transient (∆V) is approximately 80V if the
current controllers are set up correctly and the voltage controller uses the default gain. (Operating with maximum voltage on the motor, i.e. above
base speed, gives the biggest transient of power and hence the biggest value of ∆V.)

If the load change, drive voltage rating, motor voltage or DC Bus set-point are different then ∆V is calculated from:
∆V = 80V x KL X KRAT x KMV X KSP
Where:
KL = load change / 200%
KRAT = Drive voltage rating / 400
KMV = motor voltage / 400
KSP = 700 / DC Bus voltage set point
In some applications, particularly with a high d.c. bus voltage set point and low switching frequency it may be necessary to limit the rate of change of
power flow to prevent over voltage trips. A first order filter on the torque reference of the motor drive (i.e. using Pr 4.12) is the most effective method
to reduce the transient further. (A fixed limit of the rate of change of torque demand is less effective.) The following table gives an approximate
indication of the reduction in ∆V for different time constants. (As already mentioned the value of ∆V given if for an instantaneous change of torque
representing the worst case. In applications where a speed controller is used in the motor drive the transient will already include an inherent filter).

Time constant Change in ∆V

20mS x 0.75
40mS x 0.5

The transient produced is approximately proportional to the voltage controller gain. The default voltage controller gain is set to give a value that is
suitable for most applications. The gain may need to be increased if the DC Bus capacitance is high compared to two drives of similar rating coupled
together. However, care must be taken to ensure that the gain is not too high as this can cause excessive ripple in the DC Bus voltage.

Power feed-forward compensation can be used to reduce the transient DC bus voltage produced when a fast load transient occurs on drives
connected to the Regen drive. 100.0% power feed-forward is equivalent to an active current of Rated drive current / 0.45 (i.e. over current trip level)
and an AC terminal peak phase voltage equal to DC_VOLTAGE_MAX / 2. This scaling is the same as the power output from Pr 5.03 when high speed
output mode is used (see section 9.7 Menu 7: Analogue I/O ). Therefore an analogue output of the drive supplying the load and analogue input 2 or 3
of the drive acting as the supply Regen drive can be connected together to give power feed-forward compensation without further scaling if the two
drives are of equal rating. If the ratings are different the analogue input scaling must be used to give the correct power feed-forwards, where the
scaling is given by:

This parameter defines the strategy used for current trimming in regen mode. If Pr 3.11=0 then current trimming is only carried out once after power-
up. If Pr 3.11=1 current trimming is carried out after power-up and then before the drive runs each time it is enabled.

9.4 Menu 4: Current control

In Regen mode the drive operates in a reference frame that is aligned to the voltage at the drive terminals. Because the phase shift across the input
inductors is small, the reference frame is approximately aligned with the supply voltage. The maximum normal operating current is controlled by the
current limits.
DRIVE_CURRENT_MAX is used in calculating the maximum of some parameters and is fixed at 1.75 x rated drive current. The drive can operate up
to this level under normal conditions.
The relationship between the voltage and current for Regen mode operation is shown in the following vector diagram.

The Maximum current is either (1.75 x Rated drive current) when the rated current set by Pr 5.07 (or Pr 21.07 if motor map 2 is selected) is less
than or equal to the maximum Heavy Duty current rating, otherwise it is (1.1 x Maximum rated current).
The rated active and rated magnetising currents are calculated from regen mode rated current (Pr 5.07) as:
rated active current = regen mode rated current
rated magnetising current = 0
In this mode the drive only requires the regen mode rated current to set the maximum current limit correctly and scale the current limits, and so no
auto-tuning is required to set these accurately.
It is possible to set a level of reactive current with Pr 4.08 in regen mode. This parameter has a limit defined as REGEN_REACTIVE_MAX that is
provided to limit the total current to DRIVE_CURRENT_MAX.

Current limits are provided in regen mode, however, if the current limits are active the DC link voltage can no longer be controlled. The motoring
current limit applies with either phase rotation at the input when power is being taken from the supply. Similarly the regen current limit applies with
either phase rotation at the input when power is being fed back into the supply. The symmetrical current limit can override either motoring or
regenerating current limit if it is set at a lower value than either limit.

In regen mode it is possible to produce some current in the x axis of the reference frame so that the Regen drive can be made to produce or consume
reactive power. This parameter defines the level of reactive current as a percentage of the regen mode rated current (Pr 5.07). Positive reactive
current produces a component of current flowing from the supply to the drive at the Regen drive terminals that lags the respective phase voltage, and
negative reactive current produces a component of current that leads the respective voltage. It should be noted that the maximum current in regen
mode is limited to DRIVE_CURRENT_MAX, and so the drive applies a limit to this parameter (REGEN_REACTIVE_MAX) to limit the current
magnitude. Therefore the symmetrical current limit (Pr 4.07) must be reduced below its maximum value before this parameter can be increased from
zero.

The defaults Kp and Ki gains should be suitable for the standard regen inductors.
Setting the current controller gains
The most critical parameter for stability is the current controller proportional gain (Pr 4.13). The required value for this is dependent on the Regen unit
input inductance. If the inductance of the supply is a significant proportion of the recommended regen inductor (i.e. 60/IDR mH per phase, where IDR
is equivalent to Kc), then the proportional gain may need to be increased. The supply inductance is likely to be negligible compared to the regen
inductor value with small drives, but is likely to be significant with larger drives.
The proportional gain Pr 4.13 should be adjusted as described below using the total inductance per phase. The current controller integral gain Pr 4.14
is not so critical, and in a majority of cases the default value is suitable. However, if it is necessary to adjust this parameter it should be set up as
described below using the supply resistance for one phase.
The proportional gain Kp (Pr 4.13) is the most critical value in controlling the performance of the current controllers. The value can be set by the user
so that :
Kp = (L / T) x (Ifs / Vfs) x (256 / 5)
Where:
T is the sample time of the current controllers. The drive compensates for any change of sample time, and so it should be assumed that the sample
time is equivalent to the lowest sample rate of 167µs.
L is the total inductance per phase.
Ifs is the peak full scale current feedback = Kc x √2 / 0.45. Where Kc is the current scaling for each size of drive.
Vfs is the maximum DC link voltage.

Therefore:
Kp = (L / 167µs) x (Kc x √2 / 0.45 / Vfs) x (256 / 5) = K x L x Kc
Where:
K = [√2 / (0.45 x Vfs x 167µs)] x (256 / 5)

There is one value of the scaling factor K for each drive voltage rating as shown in the table below.

Drive voltage rating Vfs K

200V 415V 2322
400V 830V 1161
575V 990V 973
690V 1190V 809
The integral gain Ki (Pr 4.14) is less critical and should be set so that:
Ki = Kp x 256 x T / τm
Where:
τm is the time constant (L / R).
R is the resistance of the supply for one phase.

Therefore:
Ki = (K x L x Kc) x 256 x 167µs x R / L = 0.0427 x K x R x Kc

The above equations give the gain values that should give the best response at all switching frequencies with minimal overshoot. If required the gains
can be adjusted to improve performance as follows:
1. The integral gain (Ki) can be used to improve the performance of the current controllers by reducing the effects of inverter non-linearity. These
effects become more significant with higher switching frequency. These effects will more significant for drives with higher current ratings and
higher voltage ratings. If Ki is increased by a factor of 4 it is possible to get up to 10% overshoot in response to a step change of current
reference. For high performance applications, it is recommended that Ki is increased by a factor of 4 from the auto-tuned values. As the inverter
non-linearity is worse with higher switching frequencies it is may be necessary to increase Ki by a factor of 8 for operation with 16kHz switching
frequency.
2. It is possible to increase the proportional gain (Kp) to reduce the response time of the current controllers. If Kp is increased by a factor of 1.5 then
the response to a step change of reference will give 12.5% overshoot. It is recommended that Ki is increased in preference to Kp.

Pr 4.25 for the standard drive is used to select the Low Speed Thermal Protection Mode. This is not applicable for Regen drive because operation
below 30Hz is not possible as synchronisation to the AC supply is lost. Therefore Pr 4.25 should be left at the default 0.
If the rated current (Pr 5.07) is less or equal to the maximum Heavy Duty rating then the maximum value for K is 1.05, so the regen inductor can
operate continuously up to 105% current across the whole operating frequency range (48Hz to 65Hz).
If the rated current (Pr 5.07) is above the maximum Heavy Duty rating the maximum value for K is 1.01, so the regen inductor can operate
continuously up to 101% current across the whole operating frequency range (48Hz to 65Hz).
When the estimated temperature reaches 100% the drive takes some action depending on the setting of Pr 4.16. If Pr 4.16 is 0, the drive trips when
the threshold is reached. If Pr 4.16 is 1, the current limit is reduced to (K - 0.05) x 100% when the temperature is 100%. The current limit is set back
to the user defined level when the temperature falls below 95%. In servo and regen modes the current magnitude and the active current controlled by
the current limits should be similar, and so this system should ensure that the regen inductor operates just below its thermal limit.
The time for some action to be taken by the drive from cold with constant current is given by:
Ttrip = -(Pr 4.15) x ln(1 - (K x Pr 5.07 / Pr 4.01)2)
Alternatively the thermal time constant can be calculated from the trip time with a given current from
Pr 4.15 = -Ttrip / ln(1 - (K / Overload)2)
For example, if the drive should trip after supplying 150% overload for 60seconds with K = 1.05 then
Pr 4.15 = -60 / ln(1 - (1.05 / 1.50)2) = 89
The thermal protection system can be used in regen mode to protect the regen inductors. The rated current (Pr 5.07) should be set to the rated
current for the inductors.
The thermal model temperature accumulator is reset to zero at power-up and accumulates the temperature of the regen inductor whilst the drive
remains powered-up. Each time Pr 11.45 is changed, or the rated current defined by Pr 5.07 is altered, the accumulator is reset to zero.

This parameter defines the required switching frequency. The drive may automatically reduce the actual switching frequency (without changing this
parameter) if the power stage becomes too hot. The switching frequency can reduce from 12kHz to 6kHz to 3kHz, or 16kHz to 8kHz to 4kHz. An
estimate of the IGBT junction temperature is made based on the heatsink temperature and an instantaneous temperature drop using the drive output
current and switching frequency. The estimated IGBT junction temperature is displayed in Pr 7.34. If the temperature exceeds 135°C the switching
frequency is reduced if this is possible (i.e >4kHz) and this mode is enabled (see Pr 5.35 on page 109). Reducing the switching frequency reduces the
drive losses and the junction temperature displayed in Pr 7.34 also reduces. If the load condition persists the junction temperature may continue to
rise. If the temperature exceeds 145°C and the switching frequency cannot be reduced the drive will initiate an O.ht1 trip. Every 20ms the drive will
attempt to restore the switching frequency if the higher switching frequency will not take the IGBT temperature above 135°C. The following table gives
the sampling rate for different sections of the control system for different switching frequencies.

This bit is a duplicate of Pr 8.09 and reflects the state of the enable input. If the destination of one of the drive digital I/O (Pr 8.21 to Pr 8.26) is set to
Pr 6.29 and the I/O is set as an input the state of the input does not affect the value of this parameter as it is protected, however, it does provide a fast
disable function. The secure disable input to the drive (T31) disables the drive in hardware by removing the gate drive signals from the inverter IGBT's
and also disables the drive via the software system. When the drive is disabled by de-activating the secure disable input there can be a delay of up to
20ms. However, if a digital I/O is set up to provide the fast disable function it is possible to disable the drive within 600µs of de-activating the input. To
do this the enable signal should be connected to both the secure disable (T31) and to the digital I/O selected for the fast disable function. The state of
the digital I/O including the effect of its associated invert parameter is ANDed with the secure disable to enable the drive.
If the safety function of the Secure Disable input is required then there must not be a direct connection between the Secure Disable input (T31) and
any other digital I/O on the drive. If the safety function of the Secure Disable input and the fast disable function is required then the drive should be
given two separate independent enable signals. A safety related enable from a safe source connected to the Secure Disable input on the drive. A
second enable connected to the digital I/O on the drive selected for the fast disable function. The circuit must be arranged so that a fault which causes
the fast input to be forced high cannot cause the Secure Disable input to be forced high, including the case where a component such as a blocking
diode has failed.

The drive sets bit 0 when defaults have been loaded and the associated parameter save has been completed. The drive does not reset this flag
except at power-up. This flag is intended to be used by SM-Applications option module programs to determine when the default loading process is
complete. For example an application may require defaults that are different from the standard drive defaults. These may be loaded and another
parameter save initiated by the SM-Applications module when this flag is set. The flag should then be cleared so that the next event can be detected.
Drive mode changed (Bit 1)
The drive sets bit 1 when the drive mode has changed and the associated parameter save has been completed. The drive does not reset this flag
except at power-up. This flag is intended to be used in a similar way as bit 0.

When the control word is enabled (Pr 6.43 = 1), and the Auto/manual bit (bit7) are both one, bits 0 to 6 and bit 9 of the control word become active.
The equivalent parameters are not modified by these bits, but become inactive when the equivalent bits in the control word are active. When the bits
are active they replace the functions of the equivalent parameters. For example, if Pr 6.43 = 1 and bit 7 of Pr 6.42 = 1 the drive enable is no longer
controlled by Pr 6.15, but by bit 0 of the control word. If either Pr 6.43 = 0, or bit 7 of Pr 6.42 = 0, the drive enable is controlled by Pr 6.15.
Bit 8: Analogue/preset reference
When the control word is enabled (Pr 6.43) bit 8 of the control word becomes active. (Bit 7 of the control word has no effect on this function.) The state
of bit 8 is written to Pr 1.42. With default drive settings this selects analogue reference 1 (bit8 = 0) or preset reference 1 (bit8 = 1). If any other drive

When the control word is enabled (Pr 6.43) bit 12 of the control word becomes active. (Bit 7 of the control word has no effect on this function.) When
bit 12 is set to one a CL.bit trip is initiated. The trip cannot be cleared until the bit is set to zero
Bit 13: Reset drive
When the control word is enabled (Pr 6.43) bit 13 of the control word becomes active. (Bit 7 of the control word has no effect on this function.) When
bit 13 is changed from 0 to 1 the drive is reset. This bit does not modify the equivalent parameter (Pr 10.33).
Bit 14: Keypad watchdog
When the control word is enabled (Pr 6.43) bit 14 of the control word becomes active. (Bit 7 of the control word has no effect on this function.) A
watchdog is provided for an external keypad or other device where a break in the communication link must be detected. The watchdog system can be
enabled and/or serviced if bit 14 of the control word is changed from zero to one with the control word enabled. Once the watchdog is enabled it must
be serviced at least once every second or an “SCL” trip occurs. The watchdog is disabled when an “SCL” trip occurs, and so it must be re-enabled
when the trip is reset.

Coding

Update rate Background

The drive can operate from either a high voltage supply or a low voltage supply, usually from a battery. Different methods are used to connect the low
voltage battery supply depending on the frame size of the drive. This parameter, which indicates which supply is active, is set up to the correct value
just as the UU trip is reset. A low voltage battery supply should not be used without first consulting the appropriate documentation on the power and
control connections required for this mode.
0: Normal high voltage supply
The drive is operating in normal high voltage supply mode.
SP1xxx, SP2xxx, SP3xxx:
The drive is using the main power terminals to derive its control supplies. The drive will operate normally. Parameters that are saved at power-down
are saved when the supply is removed and a UU trip occurs.
SP4xxx, SP5xxx, SP6xxx, SPMxxxx:
The drive is using the main power terminals to derive its control supplies and the battery mode enable power supply input has no supply connected.
The drive will operate normally. Parameters that are saved at power-down are saved when the supply is removed and a UU trip occurs
1: Low voltage battery supply
The drive is operating in low voltage battery supply mode.
SP1xxx, SP2xxx, SP3xxx:
The drive is using the low voltage auxiliary power input to derive the power circuit supplies (i.e. gate drives, fans, etc.). The main power terminals can
be connected to a different supply of any voltage up to the maximum normal supply level. All parameters voltage based parameters are calculated
from the auxiliary supply level and not the supply from the main power terminals. If the auxiliary supply and the main supply are different then these
parameters will not be correct. Parameters that are saved at power-down are not saved when the power is removed in this mode.
SP4xxx and larger:
The drive is using the battery mode enable input to derive the power circuit supplies (i.e. gate drives, fans, etc.) A low voltage DC supply is connected
to the DC power terminals. All parameters that are calculated based on voltage are derived from the voltage connected to the power terminals.
Parameters that are saved at power-down are not saved when the power is removed in this mode.
For all sizes of drive in low voltage battery mode, 24V must also be supplied via the 24V control board power supply input. The drive will operate
normally except that mains loss detection is disabled, the braking IGBT will only operate when the drive is enabled, and the voltage levels contained
in the following table are used instead of the normal high voltage levels whatever the voltage rating of the drive.

Voltage level
DC_VOLTAGE_MAX Pr 6.46 x 1.45
Braking IGBT threshold voltage Pr 6.46 x 1.325
Under voltage trip level 36V
Restart voltage level after UU trip 40V
Full scale voltage measurement and the over voltage trip level are defined by DC_VOLTAGE_MAX. However, the maximum level of the low voltage
battery supply voltage should not normally exceed 90% of this value to avoid spurious over voltage trips.

This parameter defines the nominal supply voltage when operating in low voltage mode. The actual value of the parameter is not used directly by the

Update rate Background

When power modules are connected in parallel various trips can be initiated from the power modules themselves. To aid identification of the source of
the trip the module number of the source can be stored in the module number and trip time log (Pr 10.41 to Pr 10.51). If the drive is a single module
drive the module number that is stored is normally zero. However, a UNISP6xxx or UNISP7xxx drive can be fitted with the interface circuits normally
intended for parallel operation, but it is a single module drive. In this case a module number of 1 is stored.
If Pr 6.49 is zero the module number is stored in the module number and trip time log. If this parameter is one, either the powered-up clock or run time
clock is stored in the module number and trip time log as defined by Pr 6.28. It should be noted that changing this parameter clears the trip, and
module number and trip time logs.

The drive comms system 128 bytes buffer used with ANSI or Modbus rtu protocols via the 485 connector can be controlled by a Solutions Module
under certain circumstances. This parameter shows which node has control of the buffer (0 (drv) = drive, 1 (Slot1) = Solutions Module in slot 1, etc. If
a Solutions Module has control of the buffer the drive will use an alternative buffer for 485 comms and the following restrictions will apply:
1. Comms messages via the 485 port are limited to a maximum of 32 bytes
2. The 6 pin keypad port will operate correctly with an LED keypad, but it will no longer operate with an LCD keypad
3. Modbus messages using the CMP protocol can only route messages to nodes within the drive. It will not be possible for these to be routed further,
i.e. via CT Net on an SM-Applications module.

The drive has three analogue inputs (AI1 to AI3) and two analogue outputs (AO1 and AO2). Each input has a similar parameter structure and each
output has a similar parameter structure. The nominal full scale level for inputs in voltage mode is 9.8V. This ensures that when the input is driven
from a voltage produced from the drive's own 10V supply, the input can reach full scale.

The analogue inputs are sampled every 4ms except where the destinations shown in the table below are chosen, the input is in voltage mode and
other conditions necessary for short cutting are met.

Pr 4.08 - Torque reference
The window filter applied to analogue input 1 (see Pr 7.26) can be set to a time that is shorter than 4ms. There is no advantage in doing this, as it
simply reduces the resolution of the input data, which is still only sampled and routed to its destination parameter every 4ms.
Analogue outputs are updated every 4ms except when one of the following is the source and high speed update mode is selected. In high speed
mode the output operates in voltage mode, is updated every 250µs, special scaling is used as described in the table and the user scaling is ignored.
Output source Scaling
Pr 4.02 - torque prod current 10.0V = Rated drive current / 0.45
Pr 4.17 - magnetising current 10.0V = Rated drive current / 0.45
The output is the product of the active current and the voltage component in phase
with the active current (vsy x isy).
Pr 5.03 - output power 10V would be produced when:
Active current = Rated drive current / 0.45
Peak phase voltage in phase with the active current = DC_VOLTAGE_MAX / 2

For drive sizes SP1xxx to SP5xxx two temperatures are available from the power circuit, and these are displayed in Pr 7.04 and Pr 7.05. For drive
sizes SP0xxx, SP6xxx and SPMxxxx three temperatures are available from the power circuit, and these are displayed in Pr 7.04, Pr 7.05 and Pr 7.36.
If SPMxxxx drives consist of more that one parallel power module the temperatures displayed are the highest value from any of the parallel modules.
If the temperature displayed in Pr 7.04, Pr 7.05 or Pr 7.36 exceeds the trip threshold for the parameter, the drive does not have parallel power
modules and is not a single power module that uses the parallel power module hardware, an Oht2 trip is initiated. This trip can only be reset if the
parameter that has caused the trip falls below the trip reset level. If the temperature exceeds the alarm level a "hot" alarm is displayed. If the
temperature for any of these monitoring points is outside the range -20°C to 150°C it is assumed that the monitoring thermistor has failed and a
hardware fault trip is initiated (Pr 7.04 - HF27, Pr 7.05 and Pr 7.36 - HF28).

Additional monitoring is used with drives sizes SP6xxx and SPMxxxx to detect failure of the power stage cooling fan. If this fan fails the monitoring
point used to derive power stage temperature 1 that is nearest the fan will rise temperature above it s normal level, but not above the trip temperature
for power stage. This is detected and can initiate an Oht2 trip. The trip thresholds are show below.

The control board temperature is also monitored and displayed in Pr 7.06. If the temperature displayed exceeds 92°C an O.Ctl trip is initiated, and this
trip can only be reset if the temperature falls below 87°C. If the temperature exceeds 85°C a "hot" alarm is displayed. If the temperature is outside the
range from -20°C to 150°C it is assumed that the monitoring thermistor has failed and an HF29 hardware fault trip is initiated.
Drive cooling fan
The drive cooling fan is controlled by the temperature from monitoring points and other actions as follows:
1. If Pr 6.45 = 1 the fan is at full speed for at least 10s.
2. If an option module indicates that it is too hot the fan is at full speed for at least 10s.
3. For drive sizes SP0xxx to SP2xxx the fan is at full speed if the drive is enabled and the highest power circuit temperature (Pr 7.04 or Pr 7.05) or
the temperature calculated for the case of the IGBT package exceed the threshold for the drive. The fan is at its low speed if this temperature falls
to 5°C below the threshold or the drive is disabled and the temperature is below the alarm level for Pr 7.04 and Pr 7.05.
4. For drive sizes SP3xxx to SPMxxxx the fan speed is controlled above its minimum level if the drive is enabled and the highest power circuit
temperature (Pr 7.04, Pr 7.05 or Pr 7.36) or the temperature calculated for the case of the IGBT package exceed the lower threshold for the drive.
The maximum fan speed is reached when the highest of these temperatures exceeds the upper threshold. The fan is at its minimum speed if the
drive is disabled and the temperature is below the alarm level for Pr 7.04, Pr 7.05 and Pr 7.36.
The thresholds are given in Table 9-13 in °C.

In voltage mode the output range is -10V to 10V. If the scaling parameter is 1.000 then -10V and 10V are produced when the source parameter is at -

100% the output is clamped within the +/-10V range.
In current modes with a scaling parameter of 1.000 the minimum and maximum current are produced when the source parameter is at 0 and

Pr 7.23. If the result of the scaling produces an output of more than 100% the output is clamped at 20mA
If high speed update mode is selected and the source for the output is one of the parameters designated for high speed analogue output operation
(see start of this section) the output is updated at a higher rate with special scaling. If the parameter selected is not designated for this mode the
output is updated at the normal rate. If speed feedback or power is selected for high speed mode for both analogue output 1 and analogue output 2

Setting this bit will cause the drive to re-calibrate the full scale level of analogue input 1 provided the input voltage is below +1.5V or above +2.5V. This
parameter is cleared by the software automatically when the calibration is complete. If the input voltage is above +2.5V the input voltage itself is used
for calibration, and so after calibration this level will be full scale for the input. If the input voltage is below +1.5V the internal reference is used for
calibration, and so the full scale will be nominally 9.8V after calibration. The calibration level is automatically stored on power-down. It should be noted
that the Analogue input 1 offset trim is included in the input voltage when the input voltage itself is used for calibration, but this trim is not included
when the internal reference is used for calibration.

Analogue input 1 is filtered using a window filter to remove quantisation noise and adjust the resolution of this input. The length of the window can be
adjusted with this parameter. The shortest possible window is 250µs. It should be noted that if this input is not used as a speed reference (Pr 1.36,
Pr 1.37) or as a hard speed reference ({Pr 3.22) the sample time affects the resolution. The nominal resolution is given by Pr 7.26 x 500 x 103,
therefore the default setting gives approximately 11 bit resolution.

When analogue input 1 is calibrated the number of V to F converter counts is measured by the drive over 64ms and the result is stored in this
parameter. The maximum input frequency is 2.4MHz, and so the maximum for this parameter is 153600. If calibration is performed so that the drive
10V reference is used this parameter is zero. It should be noted that although the input frequency for a 10V input is nominally 2.0MHz the resolution
is not given by 2.0MHz x sample period, but due to the structure of the V to F system the resolution is 500kHz x sample period.

The drive has eight digital I/O terminals (T22, T24 to T29 and the relay) and an enable input. Each input has the same parameter structure. The digital
I/O is sampled every 4ms, except when inputs are routed to the limit switches Pr 6.35 and Pr 6.36 when the sample time is reduced to 250µs. Any
changes to the source/destination parameters only become effect after drive reset is activated.

Unidrive SP has a dedicated hardware enable input which always controls Pr 6.29. If the enable is inactive the IGBT firing signals are turned off
without software intervention. As default (Pr 8.10 = 0) the drive is in the inhibit mode when the enable is inactive. Setting this parameter to one causes
the enable to behave as an Et trip input. When the input becomes inactive an Et trip is initiated. This does not affect Pr 10.32 (Et trip parameter),
therefore an Et trip can be initiated in this mode either by making the enable inactive or setting Pr 10.32 to one.

Menu 9 contains 2 logic block functions (which can be used to produce any type of 2 input logic gate, with or without a delay), a motorised pot function
and a binary sum block. One menu 9 or one menu 12 function is executed every 4ms. Therefore the sample time of these functions is 4ms x number
of menu 9 and 12 functions active. The logic functions are active if one or both the sources are routed to a valid parameter. The other functions are
active if the output destination is routed to a valid unprotected parameter.

If the delay parameter is positive, the delay ensures that the output does not become active until an active condition has been present at the input for
the delay time as shown below.

If the delay parameter is negative, the delay holds the output active for the delay period after the active condition has been removed as shown below.
Therefore an active input that lasts for 4ms or more will produce an output that lasts at least as long as the delay time.

This parameter defines the time period which must elapse between consecutive braking periods of maximum braking power as defined by Pr 10.30.
The setting of this parameter is used in determining the thermal time constant of the resistor fitted. It is assumed that the temperature will fall by 99%
in this time, and so the time constant is Pr 10.30 / 5. If either Pr 10.30 or Pr 10.31 are set to 0 then no braking resistor protection is implemented.
The braking resistor temperature is modelled by the drive as shown below. The temperature rises in proportion to the power flowing into the resistor
and falls in proportion to the difference between the resistor temperature and ambient.

Assuming that the full power braking time is much shorter than the full power braking period (which is normally the case) the values for Pr 10.30 and
Pr 10.31 can be calculated as follows:
Power flowing into the resistor when the braking IGBT is on, Pon = Full braking volts2 / R
Where:
Full braking volts is defined in the table and R is the resistance of the braking resistor.

Full power braking time (Pr 10.30), Ton = E / Pon

Where:
E is the total energy that can be absorbed by the resistor when its initial temperature is ambient temperature.
Therefore full power braking time (Pr 10.30), Ton = E x R / Full braking volts2

If the cycle shown in the diagram above is repeated, where the resistor is heated to its maximum temperature and then cools to ambient.
The average power in the resistor, Pav = Pon x Ton / Tp
Where:
Tp is the full power braking period
Pon = E / Ton
Therefore Pav = E / Tp
Therefore full power braking period (Pr 10.31), Tp = E / Pav

The resistance and the braking resistor R, the total energy E and the average power Pav can normally be obtained for the resistor and used to
calculate Pr 10.30 and Pr 10.31.
If the profile of the power flowing from the motor is know then the instantaneous temperature can be calculated at any point by simulating the braking
resistor with the model shown below.

-t/Tp
Power from motor 100% x (1-e ) Braking energy overload
PAv accumulator Pr 10.39

The temperature of the resistor is monitored by the braking energy accumulator (Pr 10.39). When this parameter reaches 100% the drive will trip if
Pr 10.37 is 0 or 1, or will disable the braking IGBT until the accumulator falls below 95% if Pr 10.37 is 2 or 3. The second option is intended for
applications with parallel connected DC buses where there are several braking resistors, each of which cannot withstand full DC bus voltage
continuously. The braking load will probably not be shared equally between the resistors because of voltage measurement tolerances within the
individual drives. However, once a resistor reaches its maximum temperature its load will be reduced, and be taken up by another resistor.

If Pr 10.34 is set to zero then no auto reset attempts are made. Any other value will cause the drive to automatically reset following a trip for the
number of times programmed. Pr 10.35 defines the time between the trip and the auto reset (this time is always at least 10s for OI.AC, OI.br trips,
etc.). The reset count is only incremented when the trip is the same as the previous trip, otherwise it is reset to 0. When the reset count reaches the
programmed value, any further trip of the same value will not cause an auto-reset. If there has been no trip for 5 minutes then the reset count is
cleared. Auto reset will not occur on a UU, Et, EEF or HFxx trips. When a manual reset occurs the auto reset counter is reset to zero.

When a trip occurs the reason for the trip is put into the top location in the trip log (Pr 10.20). At the same time either the time from the powered-up
clock (if Pr 6.28 = 0) or from the run time clock (if Pr 6.28 = 1) is put into Trip 0 time (Pr 10.41 and Pr 10.42). The times for earlier trips (Trip 1 to 9) are
moved to the next parameter in the same way that trips move down the trip log. The time for Trips 1 to 9 are stored as the time difference between
when Trip 0 occurred and the relevant trip in hours and minutes. The maximum time difference that can be stored is 600 hours. If this time is
exceeded the value stored is 600.00.
If the powered-up clock is used as the source for this function all the times in the log are reset to zero at power-up because they were related to the
time since the drive was powered-up last time. If the runtime clock is used the times are saved at power-down and then retained when the drive
powers up again. If Pr 6.28, which defines the clock source, is changed by the user the whole trip and trip time logs are cleared. It should be noted
that the powered-up time can be modified by the user at any time. If this is done the values in the trip time log remain unchanged until a trip occurs.
The new values put in the log for earlier trips (Trip 1 to 9) will become the time difference between the value of the power-up clock when the trip
occurred and the value of the powered-up clock when the latest trip occurred. It is possible that this time difference may be negative, in which case
the value will be zero.

There will always be a finite delay between the end of a message from the host (master) and the time at which the host is ready to receive the
response from the drive (slave). The drive does not respond until at least 1ms after the message has been received from the host allowing 1ms for the
host to change from transmit to receive mode. This delay can be extended using Pr 11.26 if required for both ANSI and Modbus RTU protocols.

Note that the drive holds its own transmit buffers active for up to 1ms after it has transmitted data before switching to the receive mode, and so the
host should not send any data during this time.
Modbus RTU uses a silent period detection system to detect the end of a message. This silent period is either the length of time for 3.5 characters at

Drive mode Regen
Bit SP FI DE Txt VM DP ND RA NC NV PT US RW BU PS
Coding
1 1 1
Range Regen 0 to 1,000
Default Regen 0
Update rate Background

Data blocks are stored on a SMARTCARD with header information which includes a number which identifies the block. The header information also
includes the type of data stored in the block, the drive mode if the data is parameter data, the version number and a checksum. This data can be
viewed through Pr 11.38 to Pr 11.40 by increasing or decreasing Pr 11.37. This parameter jumps between the data numbers of the data blocks
present on the card inserted into the drive. If this parameter is set to 1000 the checksum parameter shows the number of bytes left on the card. If
there is no data on the card Pr 11.37 can only have values of 0 or 1000.
The actions of erasing a card, erasing a file, changing a menu 0 parameter, or inserting a new card will effectively set Pr 11.37 to 0 or the lowest data
block number in the card.
Data transfer and erasing can be performed by entering a code in Pr x.00 and then resetting the drive as shown in the table below.

Code Action
3yyy Transfer drive EEPROM data to a SMARTCARD block number yyy
4yyy Transfer drive data as difference from defaults to SMARTCARD block number yyy
5yyy Transfer drive ladder program to SMARTCARD block number yyy
6yyy Transfer SMARTCARD data block yyy to the drive
7yyy Erase SMARTCARD data block yyy
8yyy Compare drive parameters with block yyy
9999 Erase SMARTCARD
9888 Set SMARTCARD read-only flag
9777 Clear SMARTCARD read-only flag

Data blocks with numbers from 1 to 499 can be created or erased by the user. Data block with numbers 500 and above are read only and cannot be
created or erased by the user. The whole card may be protected from writing or erasing by setting the read-only flag (i.e if the flag is set then only
codes 6yyy or 9777 are effective).
If the destination drive has a different drive mode to the parameters on the card, the drive mode will be changed by the action of transferring
parameters from the card to the drive.
After an attempt to read, write or erase a trip may occur, see Pr 10.20 on page 148 for details. If the card is removed during data transfer from the card
for a data block that was saved with code 3yyy, the drive EEPROM checksum will be set up to be incorrect and an EEF trip will be initiated. If the card
is removed during data transfer from the card for a data block that was saved with code 4yyy then no data will be saved to EEPROM and a C.Acc trip
will be initiated. It should be noted that in both cases the parameters held in drive parameter RAM are likely to be incorrect.
During SMARTCARD or EEPROM data transfer the user will not be able to exit keypad edit mode when the current parameter is in menu 0.
Parameter data block when 3yyy is used to transfer data to a card
The data blocks contain the complete data from the drive EEPROM, i.e. all user save (US) except the parameters with the NC coding bit set. Power-
down save (PS) are not saved to the SMARTCARD. A SMARTCARD can hold up to 4 data blocks of this type.
When the data is transferred back to a drive, using 6yyy in Pr x.00, it is transferred to the drive RAM and drive EEPROM. A parameter save is not
required to retain the data after power-down. (When parameters are copied to the drive RAM this action is performed twice to prevent interdependent
parameters from being copied incorrectly.) Before the data is taken from the card, defaults are loaded in the destination drive using the same default
code as was last used in the source drive.
The categories of modules fitted to the card data source drive are stored on the card. If these are different from the destination drive, the menus for
the slots where the Solutions Module categories are different, are not modified and so they will contain their default values, and the drive will produce
a C.Optn trip. If the data is transferred to a drive of a different voltage, or current rating from the source drive, all parameters with the RA coding bit set
(as given in the table below) are not modified and a C.rtg trip occurs.

A compare action on this data block type, setting 8yyy in Pr x.00, will compare the SMARTCARD data block with the data in the EEPROM. If the
compare is successful Pr x.00 is simply set to 0. If the compare fails a C.cpr trip is initiated.
Parameter data block when 4yyy is used to transfer data to a card
The only parameter data stored on the SMARTCARD is the number for the last set of defaults loaded and the differences from the last defaults
loaded. This requires six bytes for each parameter difference. The data density is not as high as when using the data format described in the previous
section, but in most cases the number of differences from default is small and the data blocks are therefore smaller. This method can be used for
creating drive macros. Parameters that are not transferred when using 3yyy are also not transferred with this method. Also parameters that do not
have a default value (attribute ND is set) cannot be transferred with this method (i.e. Pr 3.25 or Pr 21.20 which are the servo mode phasing angle
have no default value). Parameter RAM is used as the source of this information.
When the data is transferred back to a drive, using 6yyy in Pr x.00, it is transferred to the drive RAM and the drive EEPROM. A parameter save is not
required to retain the data after power-down. (When parameters are copied to the drive RAM this action is performed twice to prevent interdependent
parameters from not being set correctly.) The categories of modules fitted to the card data source drive are stored on the card. If these are different
from the destination drive, the menus for the slots where the Solutions Module categories are different are not modified and will contain their default
values, and the drive will produce a C.Optn trip if any of the parameters from the card are in the option menus. If the data is transferred to a drive of a
different voltage or current rating from the source drive then parameters with the RA coding bit set (see table above) will not be written to the drive and
these parameters will contain their default values. The drive will produce a C.rtg trip whether any of the parameters from the card are parameters with
the RA coding bit set or not if the current or voltage rating are different.
A compare action on this data block type, setting 8yyy in Pr x.00, will compare the SMARTCARD data block with the data in the drive RAM. If the
compare is successful Pr x.00 is simply set to 0. If the compare fails a C.cpr trip is initiated.
Drive Onboard PLC program data blocks
The Onboard PLC program from a drive may be transferred to/from internal flash memory from/to a SMARTCARD. If the ladder program is
transferred from a drive with no ladder program loaded the block is still created on the card, but contains no data. If this is then transferred to a drive,
the drive will then have no ladder program. A SMARTCARD has a capacity of 4K bytes and each block of this type can take up to 4K bytes.
SMARTCARD compare function
If 8yyy is entered in Pr x.00 and the drive is reset, data block yyy on the SMARTCARD is compared with the relevant parameters in the drive. If the
compare is successful Pr x.00 is simply set to 0. If the compare fails a C.cpr trip is initiated. This function can be used with all data block types except
type 18. If a compare is requested with data block type 18 the result will always be a C.cpr trip.

* Modes 1 and 2 are not US (i.e. not saved when drive parameters are saved), mode 3 and 4 are US.
Therefore this parameter can only be saved to EEPROM if it has a value of 0, 3 or 4.
Reading (1)
Setting Pr 11.42 to 1 and resetting the drive will load the parameters from the card into the drive parameter set and the drive EEPROM. All
SMARTCARD trips apply. When the action is complete this parameter is automatically reset to zero. Parameters are saved to drive EEPROM after
this action is complete.
NOTE
This operation is only performed if block 1 on the card is a complete copy of the EEPROM (i.e. types 1 to 5) and not a difference from default file. If
block 1 does not exist or the type is incorrect a C.typ trip occurs.
Programming (2)
Setting Pr 11.42 to 2 and resetting the drive will save the parameters in the drive EEPROM to a card, i.e. equivalent to writing 3001 to Pr x.00. All
SMARTCARD trips apply except C.Chg. If the data block already exists it is automatically over-written. When the action is complete this parameter is
automatically reset to zero.

Changing Pr 11.42 to 3 and resetting the drive will save the complete parameter set from the EEPROM to the card. All SMARTCARD trips apply,
except C.Chg. If the data block already exists it is automatically overwritten.
If the card is removed when Pr 11.42 is set to 3 Pr 11.42 will be set to 0. If a card with a file 1 is inserted into a drive the drive must overwrite the file to

ensure that the data is correct. The action of setting Pr 11.42 to 0 when a card is removed will force the user to change Pr 11.42 if auto mode is still
required. Therefore the user will need to set Pr 11.42 to 3 and press reset to write the complete parameter set to the new card. (When a parameter in
menu zero is changed, and a card is fitted, a save to EEPROM, is initiated. Only the new value of the modified parameter is written to the EEPROM
and card. If Pr 11.42 were not cleared automatically when a card is removed, then when a new card is inserted that contains data block 1 the modified
parameter would be written to the existing data block 1 on the new card. The rest of the parameters in this data block may not be the same as those
in the drive.)
When Pr 11.42 is equal to 3 and the parameters in the drive are saved, the card is also updated, therefore the card becomes a copy of the drives
stored configuration.
At power up, if Pr 11.42 is set to 3, the drive will save the complete parameter set to the card. This is done to ensure that if a card is inserted whilst the
drive is powered down the new card will have the correct data after the drive is powered up again.
Boot (4)
When Pr 11.42 is set 4 the drive operates in the same way as for Auto mode except when the drive is powered-up. At power up provided a card is
inserted in the drive and parameter data block 1 exists, it is type 1 to 5, with Pr 11.42 on the card set to 4, the parameters are automatically transferred
to the drive. If the drive mode is different from that on the card the drive gives a C.Typ trip and the data is not transferred. If the 'boot' mode is stored
in the cloning card this makes the cloning the master device This provides a very fast and efficient way of re-programming a number of drives. This
parameter is reset to 0 after the parameters have been transferred.
NOTE
This parameter has the NC (not clonable attribute) set, and so its value is not stored on a SMART card. Therefore the value of this parameter taken
from a card is always zero. However, when data is transferred to a card from the source drive the value of this parameter is held in the data block
header so that the destination drive can detect when boot transfer is required on power-up (i.e. the source drive had this parameter set to 4).

The threshold detector compares the modulus of the source input value (defined by Pr 12.03, Pr 12.23), converted to a percentage of its maximum
value, with the threshold level (Pr 12.04, Pr 12.24). If the value is greater or equal to the threshold plus half the hysteresis band (Pr 12.05, Pr 12.25)
the output becomes active, or if the value is less than the threshold minus half the hysteresis band the output becomes inactive. The output may be
inverted if required by setting the invert flag (Pr 12.06, Pr 12.26). The result is routed to the destination (defined by Pr 12.07, Pr 12.27).

The variable selectors allow two source values (defined by Pr 12.08, Pr 12.28 and Pr 12.09, Pr 12.29) to be combined as defined by the mode (Pr
12.10, Pr 12.30) to produce an output (Pr 12.12, Pr 12.32) which can be routed to the destination parameter (defined by Pr 12.11, Pr 12.31). The
actions of the variable selector are defined by the mode parameter as given below. If the mode parameter is changed or the variable selector is
disabled because neither source is routed to a valid parameter all the internal state variables (i.e. time constant accumulator, etc.) within the selector
are reset. When the Sectional control mode is selected the function is also reset, and the output is held at zero, when the control (Pr 12.15 or
Pr 12.35) is zero. It is active when the control has a non-zero value.

NOTE
A loss of resolution can be seen when routing parameter values through the variable selectors due to the maximum available resolution being two
decimal places. The variable select output is scaled to ensure a 100.00% output gives full scale output to the destination parameter. This results in the
destination parameter jumping in steps equivalent to 0.01% resolution if the destination parameter has a greater resolution than two decimal places.
Sectional control
The sectional control function is intended to apply scaling and a speed offset to a 16 bit position value to generate a new 16 bit position value. The
output can be used as an input to the position controller (menu 13) or to generate an encoder simulation output via the SM-Universal encoder plus
module. This function can be selected for either variable selector, but the description below relates to variable selector 1.

Position
d/dt 4.000 + 12.13
input 4.000

Position
Σ % output

Accumulator

Speed
input 12.14

The position input can be derived from any parameter, however it is intended to be used with a position value that has a range from 0 to 65535. The
input is scaled so that so that as Pr 12.13 is varied between -4.000 and 4.000 the proportion of the input position change added to the accumulator
varies from 0.000 to 2.000 (i.e. the change of position input value is added without scaling if Pr 12.13 is 0.000). The remainder from the scaling
division is stored and then added at the next sample to maintain an exact ratio between the position input and the position output, provided the speed
input is zero. The controller only takes the change of position from the input source parameter, and not the absolute value, so that when the controller
is first made active the output does not jump to the source position, but only moves with any changes of source position after that point in time.
The range of the output of the accumulator is 0.00% and 100.00%. Unlike other functions the value is not simply limited, but rolls under or over
respectively. Although the output destination can be any parameter it is intended to be used with a position value that has a range from 0 to 65535.
The speed input defines a speed offset with a resolution of 0.1rpm. Full scale of the source parameter corresponds to 1000.0rpm. Scaling may be
applied using Pr 12.14 to give a full scale value of 4000.0rpm. The speed input is added to the accumulator to move the output position forwards or
backwards with respect to the position input.
This sample time for this function is 4ms x number of menu 9 and 12 functions active. Extending the sample time does not cause any overflow errors
within the function, however, care must be taken to ensure that the input or output positions do not change by more than half a revolution within the
sample time, i.e for a sample time of 4ms the input or output speed should not exceed 7500rpm, for a sample time of 8ms the speed should not
exceed 3750rpm, etc. If the output of this function is to supply a reference to the position controller in menu 13 it must be the only user function in
menu 9 or 12 enabled. If another function is enabled the input to the position controller will only change every 8ms (i.e. every 2 samples of
the position controller) and the speed reference applied to the drive could be very noisy.

Subject to the limits the PID controller output is given by

output = error x [P + I/s + Ds/(0.064s + 1)]

Where:
error = reference - feedback
P = proportional gain = Pr 14.10
I = integral gain = Pr 14.11
D = differential gain = Pr 14.12
Therefore with an error of 100% and P = 1.000 the output produced by the proportional term is 100%. With an error of 100% and I = 1.000 the output
produced by the integral term will increase linearly by 100% every second. With an error that is increasing by 100% per second and D = 1.000 the
output produced by the D term will be 100%.

(Pr 14.09) is 00.00 or routed to a non-existent parameter the PID controller is still enabled provided Pr 10.01 = 1 and Pr 14.08 = 1. If the optional
enable source (Pr 14.09) is routed to an existing parameter the source parameter must be one before the PID controller can be enabled. If the PID
controller is disabled the output is zero and the integrator is set to zero.

It should be noted that if the parameter values saved in the drive EEPROM or on a SMARTCARD are all zero for menu 22 the drive will automatically
load defaults for this menu when the drive is powered up or the parameters are transferred from the SMARTCARD. This ensures that defaults are
used for this menu if the saved parameters are from a software version which did not include this menu.

*SP2404 Power and current ratings

All Unidrive SP models are dual rated except for the SP2404 which only has a Heavy Duty rating. However, if the current limits in Pr 4.05 to Pr 4.07
are set to a maximum of 110% and the switching frequency is greater than 3kHz, then the drive can be used at a maximum continuous current higher
than the Heavy Duty rating. See the Normal Duty ratings in Table 10-1, Table 10-2 and Table 10-3. Normal Duty ratings exist for the SP2404 above
3kHz when the overload is reduced from the default value 165% in open loop or 175% in closed loop, to 110%.
If the current limits in Pr 4.05 to Pr 4.07 are set higher than 110% then the Heavy Duty current ratings are applicable.

10.3.2 Common DC Bus Fusing

DC bus fusing is required in the following systems for both the regen and
motoring drives, and the SPMC if used as the external soft start circuit.

1. Single regen, multiple motoring drives

2. Multiple regen, multiple motoring drives
3. Unidrive SP regen brake resistor replacement
4. Regen systems using an SPMC
DC bus fuses as detailed following must be fitted in both the positive and
negative branches of DC Bus connections to each of the regen and
motoring drives, and the SPMC if used as the external soft start circuit.
NOTE
Ferraz have a range of DC fuses which could be used to provide the
required protection, types (00 and 21) may be used.
00 - Fuse with no trip indicator fitted
21 - Fuse fitted with trip indicator

NOTE
The DC Bus voltage set-point on a regen system (default) is set to
700Vdc, this can be up to a maximum 800Vdc. Therefore ensure the
selected DC Bus fusing is of the correct voltage rating with regards to
the DC Bus voltage level (Pr 3.05 DC Bus Voltage Set-point).

10.4.2 Softstart resistor - type TG series

The start-up circuit limits the amount of current flowing into the DC bus of
the Regen drive and motoring drive(s) when the supply is first switched
on.
The softstart resistors required for single regen multiple motoring
applications are as specified in the following table. Resistor energy pulse
rating and overload are non-standard and therefore important.
The following resistors can be configured to meet the required
resistance (series parallel arrangements).

10.4.3 Switching frequency filter

The AC input terminals of a Regen drive produce a PWM output voltage,
which has a sinusoidal component at line frequency, plus significant
harmonics at the switching frequency and its multiples.
Switching frequency filter inductors
The following inductors are standard 3-phase inductors, rated at drive
rated current for a single regen system. They carry only 50/60Hz current
with a negligible amount of high frequency current.
NOTE

The switching frequency filter inductors need to be rated to the total

current requirement of the system.

10.5.1 Varistors
AC line voltage transients can typically be caused by the switching of
large items of plant, or by lightening strikes on another part of the supply
network. If these transients are not suppressed, they can cause damage
to the insulation of the Regen inductors, or to the Regen drive
electronics. Varistors should be fitted after the supply fuses and before
the EMC filter as shown in the following.

Calculating current level on exponential curve
As shown in Figure 11-2, after 5 time constants the charging current is
approximately zero. In some cases, due to the characteristic of the
overload, the current may have to be calculated after 4 time constants to
ensure that the thermal trip area of the overload is not activated. Refer to
the following formula:
I at given Time Constant = Exp [-1 (Time Constants)] x Ipeak
The following example calculates the current level after 3 time constants
with a peak charging current of 100A:
Exp [-1 (3)] x 100 = 4.97A

11.3.3 Sizing of thermal overload

The thermal overload should be sized to provide protection against a
high impedance short circuit. Under this condition the current flowing
would not be high enough to result in the magnetic overload tripping, but
the power dissipated would exceed the nominal power rating resulting in
heating of the resistor.
In order to size the thermal overload correctly, the power rating and
overload characteristics of the resistor are required. The power
characteristic curve for the resistor should be converted from multiples of
power to current in order to size the thermal overload correctly.
