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 part 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 firmware version
This product is supplied with the latest firmware version. If this drive is to be connected to an existing system or machine, all drive
firmware versions should be verified to confirm the same functionality as drives of the same model already present. This may also
apply to drives returned from an Emerson Industrial Automation Service Centre or Repair Centre. If there is any doubt please contact

Environmental statement
Emerson Industrial Automation 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
http://www.emersonindustrial.com/en-EN/controltechniques/aboutus/environment/Pages/environment.aspx
The electronic variable-speed drives manufactured by Emerson Industrial Automation 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 must not be discarded but should instead be
recycled by a specialist recycler of electronic equipment. Recyclers will find the products easy to dismantle 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 fasteners. 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. Emerson Industrial
Automations' packaging strategy prefers 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.
REACH legislation
EC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) requires the supplier
of an article to inform the recipient if it contains more than a specified proportion of any substance which is considered by the European
Chemicals Agency (ECHA) to be a Substance of Very High Concern (SVHC) and is therefore listed by them as a candidate for
compulsory authorisation.
For current information on how this requirement applies in relation to specific Emerson Industrial Automations' products, please
approach your usual contact in the first instance. Emerson Industrial Automations' position statement can be viewed at:

Issue Number: 1
1 Safety information
1.1 Warnings, Cautions and Notes
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 Control User
Guide
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/
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 Control User Guide carefully.
The STOP and Safe Torque Off 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 function, 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 behavior 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 function 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.
1.4 Environmental limits
Instructions in the Power Installation 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 Access
Drive access must be restricted to authorized personnel only. Safety
regulations which apply at the place of use must be complied with.
1.6 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire
enclosure must be provided. For further information, refer to the relevant
Power Installation Guide.
1.7 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 ground (earth) connections.
The Power Installation 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:
Safety of Machinery 2006/42/EC.
Electromagnetic Compatibility (EMC) Directive 2014/30/EU.
1.8 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 Pr 00.006 motor rated
current. This affects the thermal protection of the motor.
1.9 Mechanical brake control
The brake control functions are provided to allow well co-ordinated
operation of an external brake with the drive. While both hardware and
software are designed to high standards of quality and robustness, they
are not intended for use as safety functions, i.e. where a fault or failure
would result in a risk of injury. In any application where the incorrect
operation of the brake release mechanism could result in injury,
independent protection devices of proven integrity must also be
incorporated.
1.10 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.
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.

1.11 Electrical installation
1.11.1 Electric shock risk
The voltages present in the following locations can cause severe electric
shock and may be lethal:
AC supply cables and 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.
1.11.2 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.
1.12 Hazard
1.12.1 Falling hazard
The drive presents a falling or toppling hazard. This can cause injury to
personnel and therefore should be handled with care.
