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.

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 Product Information
2.1 Ratings
The Unidrive SP 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, and full torque at low
speeds is not required (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
2
t software
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
For constant torque applications or applications which require a high
overload capability, or full torque is required at low speeds (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

2.1.1 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 Advanced User Guide.
Typical values are shown in the table below for closed loop vector (VT) and open loop (OL) modes:
Table 2-5 Typical overload limits for size 0 to 5
Operating mode Closed loop from cold Closed loop from 100% Open loop from cold Open loop from 100%
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 175% for 40s 175% for 5s 150% for 60s 150% for 8s
Heavy Duty overload with a typical 4 pole motor 200% for 28s 200% for 3s 175% for 40s 175% for 5s
Table 2-6 Typical overload limits for size 6
Operating mode Closed loop from cold Closed loop from 100% Open loop from cold Open loop from 100%
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
Generally the drive rated current is higher than the matching motor rated current allowing a higher level of overload than the default setting as
illustrated by the example of a typical 4 pole motor.
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.
2.2 Model number
The way in which the model numbers for the Unidrive SP range are
formed is illustrated below.
2.3 Operating modes
The Unidrive SP is designed to operate in any of the following modes:
1. Open loop mode
Open loop vector mode
Fixed V/F mode (V/Hz)
Quadratic V/F mode (V/Hz)
2. RFC mode
3. Closed loop vector
4. Servo
5. Regen
2.3.1 Open loop mode
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.
For further details refer to section 8.1.1 Open loop motor control on
page 130.
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.
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.
2.3.2 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 8.1.2 RFC mode on page 132.
2.3.3 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.
2.3.4 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.

2.3.5 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 Mechanical Installation
This chapter describes how to use all mechanical details to install the
drive. The drive is intended to be installed in an enclosure. Key features
of this chapter include:
• Through-hole mounting
• IP54 as standard or through-panel mounting
• Enclosure sizing and layout
• Solutions Module fitting
• Terminal location and torque settings
3.1 Safety information
Follow the instructions
The mechanical and electrical installation instructions must
be adhered to. Any questions or doubt should be referred to
the supplier of the equipment. It is the responsibility of the
owner or user to ensure that the installation of the drive and
any external option unit, and the way in which they are
operated and maintained, comply with the requirements of
the Health and Safety at Work Act in the United Kingdom or
applicable legislation and regulations and codes of practice in
the country in which the equipment is used.
Competence of the installer
The drive must be installed by professional assemblers who
are familiar with the requirements for safety and EMC. The
assembler is responsible for ensuring that the end product or
system complies with all the relevant laws in the country
where it is to be used.
Many of the drives in this product range weigh in excess of
15kg (33lb). Use appropriate safeguards when lifting these
models.
A full list of drive weights can be found in section
12.1.19 Weights on page 266
Enclosure
The drive is intended to be mounted in an enclosure which
prevents access except by trained and authorized
personnel, and which prevents the ingress of contamination.
It is designed for use in an environment classified as
pollution degree 2 in accordance with IEC 60664-1. This
means that only dry, non-conducting contamination is
acceptable.
3.2 Planning the installation
The following considerations must be made when planning the installation:
3.2.1 Access
Access must be restricted to authorized personnel only. Safety
regulations which apply at the place of use must be complied with.
The IP (Ingress Protection) rating of the drive is installation dependent.
For further information, please refer to section 3.9 Enclosing standard
drive for high environmental protection on page 44.
3.2.2 Environmental protection
The drive must be protected from:
• moisture, including dripping water or spraying water and
condensation. An anti-condensation heater may be required, which
must be switched off when the drive is running.
• contamination with electrically conductive material
• contamination with any form of dust which may restrict the fan, or
impair airflow over various components
• temperature beyond the specified operating and storage ranges
• corrosive gasses
During installation it is recommended that the vents on the drive are
covered to prevent debris (e.g. wire off-cuts) from entering the drive.
3.2.3 Cooling
The heat produced by the drive must be removed without its specified
operating temperature being exceeded. Note that a sealed enclosure
gives much reduced cooling compared with a ventilated one, and may
need to be larger and/or use internal air circulating fans.
For further information, refer to section 3.6.2 Enclosure sizing on
page 42.
3.2.4 Electrical safety
The installation must be safe under normal and fault conditions.
Electrical installation instructions are given in Chapter 4 Electrical
Installation on page 61.
3.2.5 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire
enclosure must be provided.
3.2.6 Electromagnetic compatibility
Variable speed drives are powerful electronic circuits which can cause
electromagnetic interference if not installed correctly with careful
attention to the layout of the wiring.
Some simple routine precautions can prevent disturbance to typical
industrial control equipment.
If it is necessary to meet strict emission limits, or if it is known that
electromagnetically sensitive equipment is located nearby, then full
precautions must be observed. In-built into the drive, is an internal EMC
filter, which reduces emissions under certain conditions. If these
conditions are exceeded, then the use of an external EMC filter may be
required at the drive inputs, which must be located very close to the
drives. Space must be made available for the filters and allowance made
for carefully segregated wiring. Both levels of precautions are covered in
section 4.11 EMC (Electromagnetic compatibility) on page 75.
3.2.7 Hazardous areas
The drive must not be located in a classified hazardous area unless it is
installed in an approved enclosure and the installation is certified.
3.3 Terminal cover removal
Isolation device
The AC supply must be disconnected from the drive using an
approved isolation device before any cover is removed 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 energized, the AC
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 authorized distributor.
3.3.1 Removing the terminal covers
Size 0 is not fitted with any terminal covers.
Size 1 is fitted with two terminal covers:
Size 2 is fitted with three terminal covers: Control, High current DC /
Braking and low voltage DC terminal covers.
Size 3 is fitted with four terminal covers: Control, High current DC /
Braking, low voltage DC and AC terminal covers.
Size 4, 5 and 6 are fitted with three terminal covers: Control, input and
output terminal covers.
