General Information
The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or incorrect
installation or adjustment of the optional operating parameters of the equipment or from mismatching the variable speed
drive with the motor.
The contents of this guide are believed to be correct at the time of printing. In the interests of a commitment to a policy
of continuous development and improvement, the manufacturer reserves the right to change the specification of the
product or its performance, or the contents of the guide, without notice.
All rights reserved. No parts of this guide may be reproduced or transmitted in any form or by any means, electrical or
mechanical including photocopying, recording or by an information storage or retrieval system, without permission in
writing from the publisher.
Drive software version
This product is supplied with the latest version of software. If this product is to be used in a new or existing system with
other drives, there may be some differences between their software and the software in this product. These differences
may cause this product to function differently. This may also apply to drives returned from a Control Techniques Service
Centre.
The software version of the drive can be checked by looking at Pr 11.29 (or Pr 0.50) and Pr 11.34. The software version
takes the form of zz.yy.xx, where Pr 11.29 displays zz.yy and Pr 11.34 displays xx, i.e. for software version 01.01.00,
Pr 11.29 would display 1.01 and Pr 11.34 would display 0.
If there is any doubt, contact a Control Techniques Drive Centre.
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 Safety Information
1.1 Warnings, Cautions and Notes
A Warning contains information which is essential for
avoiding a safety hazard.
A Caution contains information which is necessary for
avoiding a risk of damage to the product or other equipment.
A Note contains information which helps to ensure correct operation of
the product.
1.2 Electrical safety - general warning
The voltages used in the drive can cause severe electrical shock and/or
burns, and could be lethal. Extreme care is necessary at all times when
working with or adjacent to the drive.
Specific warnings are given at the relevant places in this User Guide.
1.3 System design and safety of
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/
start-up and maintenance must be carried out by personnel who have
the necessary training and experience. They must read this safety
information and this User Guide carefully.
The STOP and SAFE TORQUE OFF (SECURE DISABLE) function
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.
With the sole exception of the SAFE TORQUE OFF (SECURE
DISABLE) function, none of the drive functions must be used to
ensure safety of personnel, i.e. they must not be used for safetyrelated 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.
The SAFE TORQUE OFF (SECURE DISABLE) function has been
approved
prevention of unexpected starting of the drive. It may be used in a
safety-related application. The system designer is responsible for
ensuring that the complete system is safe and designed correctly
according to the relevant safety standards.
personnel

as meeting the requirements of EN954-1 category 3 for the
1.4 Environmental limits
Instructions in this User 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
of fuses or other protection, and protective earth (ground) connections.
This User Guide contains instruction for achieving compliance with
specific EMC standards.
Within the European Union, all machinery in which this product is used
must comply with the following directives:
98/37/EC: Safety of machinery.
89/336/EEC: Electromagnetic Compatibility.
1.6 Motor
Ensure the motor is installed in accordance with the manufacturer’s
recommendations. Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed
operation. If it is intended to use the capability of the drive to run a motor
at speeds above its designed maximum, it is strongly recommended that
the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan
becomes less effective. The motor should be installed with a protection
thermistor. If necessary, an electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection
of the motor. The default values in the drive should not be relied upon.
It is essential that the correct value is entered in parameter 0.46 motor
rated current. This affects the thermal protection of the motor.
1.7 Adjusting parameters
Some parameters have a profound effect on the operation of the drive.
They must not be altered without careful consideration of the impact on
the controlled system. Measures must be taken to prevent unwanted
changes due to error or tampering.

2 Introduction
The Unidrive Solutions Platform Modular drive offers the possibility of
implementing many custom power systems with a wide range of power
modules. The power range is 45kW to 1.9MW and the modular design of
input and output stages enables a wide range of very compact and
efficient systems to be realized. These include:
• Parallel output stages for higher power motors:
Up to a maximum of 10 SPMA/D modules
(1 master module with up to 9 slave modules, OR
1 remote mounted control master pod controlling up to 10
slaves. This allows the user to place all circuitry in one low
voltage cabinet)
• Common DC bus multi-drive systems for:
Connection to larger existing power supplies
Energy sharing between motoring and regenerating drives
• Active front end drive systems for:
Minimising supply current harmonics
Four quadrant motor control
• Multiple controlled rectifier bridges (SPMC) for:
Minimising supply current harmonics by drawing 6, 12 or 18
pulse supply load currents
• Uncontrolled rectifier bridges (SPMU) for use in applications with
poor quality power supplies, very long motor cables and where DC
bus pre-charge is done by other means
2.1 Rectifier (SPMC/U)
There are two distinct types of rectifier available
SPMC: Controlled SCR/thyristor rectifier
SPMU: Uncontrolled diode rectifier
Different current and voltage ratings are available for both types.
2.1.1 Half controlled SCR/thyristor rectifier (SPMC)
The half controlled SCR/thyristor bridge is used as a front end to the
SPMD inverter module or as a stand alone rectifier for several smaller
drives. Control wiring is linked to the inverter for trip monitoring. Softstart is built in.
SPMC14X2 and 16X1
Figure 2-1 Single half controlled SCR/thyristor
SPMC2X0X
Figure 2-2 Dual half controlled SCR/thyristor
A separate input line reactor (INLXXX) of at least the value
shown in Table 6-2 and Table 6-3 on page 68 must be used
with the rectifiers. Failure to provide sufficient reactance could
damage or reduce the service life of the rectifier or inverter.
The Unidrive SPMC is a half controlled SCR/thyristor bridge and is used
as a front end to the SPMD inverter module or as a stand alone rectifier
for several smaller drives. Soft-start is built in.
The Unidrive SPMU is used as a front end to the SPMD inverter module
or as a stand alone rectifier for several smaller drives. Softstart must be
supplied externally using a resistor and contactor or SPMC.
An external 24V, 3A power supply is required in addition to the AC
supply to allow the rectifier to operate. See section 6.14.3 Unidrive
SPMC/U control connections on page 89 and section 14.1.4 Unidrive
SPM 24V power supply on page 267. Control wiring is required between
the rectifier and motoring drive(s) so that if the rectifier indicates a fault
the motoring drive(s) will be disabled.
The 24V supply must be protected using a 4A slow-blow fuse, one for
each supply pole.
Control connections to the Unidrive SPMC/U should be made with
2
0.5mm
cable.
The status relay contacts are rated for switching non-inductive loads at
250Vac 6A non-inductive, up to 4Adc if the voltage is limited to 40V or up
to 400mA dc if the voltage is limited to 250Vdc. Protection from
overcurrent must be provided.
2.1.2 Diode rectifier (SPMU)
The uncontrolled diode rectifier is supplied as an alternative to the half
controlled SCR/thyristor rectifier. Control wiring is limited to a thermal
trip. Soft-start is achieved by the use of an external contactor and
resistor.

2.3 SPMD inverter
The SPMD is an inverter stage only (DC in to AC out). If a rectifier is required, then an SPMC or SPMU and AC input line reactor must also be
installed. It can provide a maximum continuous output current of 350A (400V drive). DC connections can be used for regen and bus-parallel
applications. The SPMD is available with or without a braking IGBT fitted.
Figure 2-6 SPMA inverter schematic
2.4 Input line reactor
The INL line reactor must be used in conjunction with the Unidrive
SPMC/U rectifiers. See section 6.2.2 Input line reactor specifications on
page 67 for further information.
Figure 2-7 Single input line reactor (INLX0X)/force cooled (INLX0XW)

3.1 Ratings
The Unidrive SPM is dual rated.
The setting of the motor rated current determines which rating applies Heavy Duty or Normal Duty.
The two ratings are compatible with motors designed to IEC60034.
The graph aside illustrates the difference between Normal Duty and
Heavy Duty with respect to continuous current rating and short term
overload limits.

Normal Duty Heavy Duty (default)
For applications which use self ventilated (TENV/TEFC) induction
motors and require a low overload capability (e.g. fans, pumps).
Self ventilated (TENV/TEFC) induction motors require increased
protection against overload due to the reduced cooling effect of the fan
at low speed. To provide the correct level of protection the I
operates at a level which is speed dependent. This is illustrated in the
graph below.
The speed at which the low speed protection takes effect can be
changed by the setting of Pr 4.25. The protection starts when the motor
speed is below 15% of base speed when Pr 4.25 = 0 (default) and below
50% when Pr 4.25 = 1.
Operation of motor I2t protection (It.AC trip)
Motor I2t protection is fixed as shown below and is compatible with:
• Self ventilated (TENV/TEFC) induction motors
2
t software
For constant torque applications or applications which require a high
overload capability (e.g. winders, hoists).
The thermal protection is set to protect force ventilated induction motors
and permanent magnet servo motors by default.
N
If the application uses a self ventilated (TENV/TEFC) induction motor
and increased thermal protection is required for speeds below 50% base
speed, then this can be enabled by setting Pr 4.25 = 1.
Motor I2t protection defaults to be compatible with:
• Forced ventilation induction motors
• Permanent magnet servo motors

The continuous current ratings given are for maximum 40°C (104°F), 1000m altitude and 3.0 kHz switching. Derating is required for higher switching
frequencies, ambient temperature >40°C (104°F), high altitude and parallel applications. For further information, refer to section 14.1.1 Power and
current ratings (Derating for switching frequency and temperature) on page 263.

The Unidrive SPMD can be connected to its rectifier module in two ways, directly above the inverter (docked) or independently mounted in
different vertical planes (undocked). Changes in the flow of air mean that the ratings are different for the two mounting methods for SPMD12x4.
For details on docking, refer to section 5.6 Docking a Unidrive SPMC/U to an SPMD on page 39.

3.1.1 Typical short term overload limits
The maximum percentage overload limit changes depending on the selected motor. Variations in motor rated current, motor power factor and motor
leakage inductance all result in changes in the maximum possible overload. The exact value for a specific motor can be calculated using the
equations detailed in Menu 4 in the Unidrive SP Advanced User Guide.
Typical values are shown in the tables below for closed loop vector (VT) and open loop (OL) modes.
Table 3-13 Typical overload limits for all Unidrive SPM modules
Operating mode
Normal Duty overload with motor rated current = drive rated current 110% for 165s 110% for 9s 110% for 165s 110% for 9s
Heavy Duty overload with motor rated current = drive rated current 150% for 60s 150% for 8s 129% for 97s 129% for 15s
Closed loop/RFC/
Servo/Regen from cold
Closed loop/RFC/Servo/
Regen from 100%
Open loop from cold Open loop from 100%
Generally the drive rated current is higher than the matching motor rated current allowing a higher level of overload than the default setting.
The time allowed in the overload region is proportionally reduced at very low output frequency on some drive ratings.
The maximum overload level which can be attained is independent of the speed.

3.2 Operating modes
The Unidrive SPM is designed to operate in any of the following modes:
1. Open loop mode
Open loop vector
Fixed V/F mode (V/Hz)
Quadratic V/F mode (V/Hz)
2. RFC mode
3. Closed loop vector
4. Servo
5. Regen
3.2.1 Open loop mode
For use with induction motors.
The drive applies power to the motor at frequencies varied by the user.
The motor speed is a result of the output frequency of the drive and slip
due to the mechanical load. The drive can improve the speed control of
the motor by applying slip compensation. The performance at low speed
depends on whether V/F mode or open loop vector mode is selected.
Open loop vector mode
The voltage applied to the motor is directly proportional to the frequency
except at low speed where the drive uses motor parameters to apply the
correct voltage to keep the flux constant under varying load conditions.
Typically 100% torque is available down to 1Hz for a 50Hz motor.
For further details refer to section 10.1.1 Open loop motor control on
page 136.
Fixed V/F mode
The voltage applied to the motor is directly proportional to the frequency
except at low speed where a voltage boost is provided which is set by
the user. This mode can be used for multi-motor applications.
Typically 100% torque is available down to 4Hz for a 50Hz motor.
Quadratic V/F mode
The voltage applied to the motor is directly proportional to the square of
the frequency except at low speed where a voltage boost is provided
which is set by the user. This mode can be used for running fan or pump
applications with quadratic load characteristics or for multi-motor
applications. This mode is not suitable for applications requiring a high
starting torque.
3.2.2 RFC mode
Rotor flux control provides closed loop control without the need for
position feedback by using current, voltages and key motor parameters
to estimate the motor speed. It can eliminate instability traditionally
associated with open loop control such as operating large motors with
light loads at low frequencies.
For further details refer to section 10.1.2 RFC mode on page 138.
3.2.3 Closed loop vector mode
For use with induction motors with a feedback device installed.
The drive directly controls the speed of the motor using the feedback
device to ensure the rotor speed is exactly as demanded. Motor flux is
accurately controlled at all times to provide full torque all the way down
to zero speed.
For further details refer to section 10.1.3 Closed loop vector motor
control on page 141.

For further details refer to section 10.1.4 Servo motor control on

3.2.5 Regen
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 SCR/thyristor front end.
See the Unidrive SP Regen Installation Guide for more information
about operation in this mode.

3.2.4 Servo
For use with permanent magnet brushless motors with a feedback
device installed.
The drive directly controls the speed of the motor using the feedback
device to ensure the rotor speed is exactly as demanded. Flux control is
not required because the motor is self excited by the permanent
magnets which form part of the rotor.
Absolute position information is required from the feedback device to
ensure the output voltage is accurately matched to the back EMF of the
motor. Full torque is available all the way down to zero speed.

Current sharing between drives
whose motor outputs are
connected in parallel
When used from a 3 phase supply, it is
preferable not to link the DC bus
because the impedance between DC
and each inverter output is just the
impedance of the output chokes. Also,
on the input side, input current sharing
is determined only by making the
temperature of the two rectifiers similar
and by ensuring that both rectifiers see
the same impedance to the line power
supply.

Current sharing between drives
whose motor outputs are
connected in parallel
When used from a 3 phase supply, it is
preferable not to link the DC bus because
the impedance between DC and each
inverter output is just the impedance of
the output chokes. Also, on the input
side, input current sharing is determined
only by making the temperature of the
two rectifiers similar and by ensuring that
both rectifiers see the same impedance
to the line power supply.
