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 Automation’s 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.
The model number may be followed by additional characters that do not affect the ratings.

NOTE
1.1Warnings, 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.
1.2Electrical 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 guide.
1.3System 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 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.
1.4Environmental 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.

For further information, refer to section 3.2.5 Fire protection on page 18.
1.7Compliance 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.
This 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:
2006/42/EC: Safety of machinery.
2004/108/EC: Electromagnetic Compatibility.
1.8Motor
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 00.046 motor rated current. This affects the
thermal protection of the motor.

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. Typical values are shown in the table below:
Table 2-4 Typical overload limits
Operating modeRFC from cold RFC from 100 %

200 % for 28 s200 % for 3 s150 % for 60 s150 % for 7 s
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.
Output current
The continuous output current ratings given on the rating label are for maximum 40 °C (104 °F), 1000
m altitude and 3 kHz switching frequency. Derating is required for higher switching frequencies,
ambient temperatures >40 °C (104 °F) and higher altitude. For derating information, refer to the
Chapter 5 Technical data on page 76.
Input current
The input current is affected by the supply voltage and impedance. The input current given on the
rating label is the typical input current and is stated for a balanced supply.

3.1Safety 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.
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 Emerson Industrial Automation or their
authorized distributor.
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.
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.

3.2.6Electromagnetic 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 4.12
(Electromagnetic compatibility) on page 63
.

For EMC compliance:
1. When using an external EMC filter, one filter is required for each drive.
2. Power cabling must be at least 100 mm (4 in) from the drive in all directions
3.5.2Enclosure sizing
1. Add the dissipation figures from section 5.1.3
to be installed in the enclosure.
2. If an external EMC filter is to be used with each drive, add the dissipation figures from section
5.2.1
EMC filter ratings
on page 96 for each external EMC filter that is to be installed in the
enclosure.
3. If the braking resistor is to be mounted inside the enclosure, add the average power figures from
for each braking resistor that is to be installed in the enclosure.
4. Calculate the total heat dissipation (in Watts) of any other equipment to be installed in the
enclosure.
5. Add the heat dissipation figures obtained above. This gives a figure in Watts for the total heat that
will be dissipated inside the enclosure.
Calculating the size of a sealed enclosure
The enclosure transfers internally generated heat into the surrounding air by natural convection (or
external forced air flow); the greater the surface area of the enclosure walls, the better is the
dissipation capability. Only the surfaces of the enclosure that are unobstructed (not in contact with a
wall or floor) can dissipate heat.

Power dissipation for the drives and the external EMC filters can be obtained from
The enclosure is to be made from painted 2 mm (0.079 in) sheet steel having a heat
transmission coefficient of 5.5 W/m2/oC. Only the top, front, and two sides of the
enclosure are free to dissipate heat.
The value of 5.5 W/m2/ºC can generally be used with a sheet steel enclosure (exact
values can be obtained by the supplier of the material). If in any doubt, allow for a greater
margin in the temperature rise.

width (W) from:
Inserting H = 2m and D = 0.6 m, obtain the minimum width:

If the enclosure is too large for the space available, it can be made smaller only by attending to one
or all of the following:
•Using a lower PWM switching frequency to reduce the dissipation in the drives
•Reducing the ambient temperature outside the enclosure, and/or applying forced-air cooling to
the outside of the enclosure
•Reducing the number of drives in the enclosure
•Removing other heat-generating equipment

3.6Enclosure design and drive ambient temperature
Drive derating is required for operation in high ambient temperatures
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 (T
) which should be used for any
rate
necessary derating to ensure sufficient cooling for the whole of the drive.

3.7 Heatsink fan operation
The drive is ventilated by an internal heatsink mounted fan. The fan housing forms a baffle plate,
channelling the air through the heatsink chamber. Thus, regardless of mounting method (surface
mounting or through-panel mounting), the installing of additional baffle plates is not required.
Ensure the minimum clearances around the drive are maintained to allow air to flow freely.
The heatsink fan on all sizes is a variable speed fan. The drive controls the speed at which the fan
runs based on the temperature of the heatsink and the drive's thermal model system. The maximum
speed at which the fan operates can be limited in Pr
derating. Refer to section 3.13.1
Fan removal procedure

. This could incur an output current
on page 44 for information on fan removal.
3.8Enclosing standard drive for high environmental protection
An explanation of environmental protection rating is provided in section 5.1.10
page 85.
The standard drive is rated to IP20 pollution degree 2 (dry, non-conductive contamination only)
(NEMA 1). However, it is possible to configure the drive to achieve IP65 rating (sizes 3 to 4) (NEMA
12) at the rear of the heatsink for through-panel mounting (some current derating is required). Refer
to Chapter 5
Technical data
on page 76.
This allows the front of the drive, along with various switchgear, to be housed in a high IP enclosure
with the heatsink protruding through the panel to the external environment. Thus, the majority of the
heat generated by the drive is dissipated outside the enclosure maintaining a reduced temperature
inside the enclosure. This also relies on a good seal being made between the heatsink and the rear
of the enclosure using the gaskets provided.

Safety informationProduct information
The main gasket should be installed as shown in Figure 3-16.
On drive sizes 3 and 4, in order to achieve the high IP rating at the rear of the heatsink it is necessary
to seal a heatsink vent by installing the high IP insert as shown in Figure 3-18 and Figure 3-19 on
page 36.
The heatsink fans have conformal coated PCBs and have sealant at cable entry points.
This means that the electronics of the fan are rated to IP54. Dripping, splashing or sprayed
water can impede the operation of the fan, therefore if the environment is such that the fan
may be subjected to more than occasional dripping or sprayed water while operational,
then suitable drip protection covers should be employed.
Figure 3-16 Installing the gasket
To seal the space between the drive and the backplate, use two sealing brackets as shown in Figure
3-17.

NOTE
The drive should be installed in a cool, clean, well ventilated location. Contact of moisture and dust
with the drive should be prevented. Regular checks of the following should be carried out to ensure
drive / installation reliability are maximized:
Environment
Ambient temperature Ensure the enclosure temperature remains at or below maximum specified
Dust
MoistureEnsure the drive enclosure shows no signs of condensation
Enclosure
Enclosure door filters Ensure filters are not blocked and that air is free to flow
Electrical
Screw connectionsEnsure all screw terminals remain tight
Crimp terminals
Cables Check all cables for signs of damage
3.13.1Fan removal procedure
Figure 3-28 Removal of the size 3 and 4 heatsink fan (size 3 shown)
Ensure the drive remains dust free – check that the heatsink and drive fan
are not gathering dust. The lifetime of the fan is reduced in dusty
environments.
Ensure all crimp terminals remains tight – check for any discoloration which
could indicate overheating
Ensure the fan cable is disconnected from the drive prior to attempting fan removal.
1. Press the two tabs inwards to release the fan from the drive frame.
2. Using the central fan tab, withdraw the fan assembly from the drive housing.
Replace the fan by reversing the above instructions.
If the drive is surface mounted using the outer holes on the mounting bracket, then the
heatsink fan can be replaced without removing the drive from the backplate.

Electric shock risk
The voltages present in the following locations can cause severe electric shock and may be
lethal:
AC supply cables and connections
DC and brake 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.
Isolation device
The AC and / or DC power 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.
STOP function
The STOP function does not remove dangerous voltages from the drive, the motor or any
external option units.
Safe Torque Off function
The Safe Torque Off function does not remove dangerous voltages from the drive, the
motor or any external option units.
Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the
AC and / or DC power supply has been disconnected. If the drive has been energized,
the AC and / or DC power 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 Emerson Industrial Automation or
their authorized distributor.
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 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).
Permanent magnet motors
Permanent magnet motors generate electrical power if they are rotated, even when the
supply to the drive is disconnected. If that happens then the drive will become energized
through its motor terminals. If the motor load is capable of rotating the motor when the
supply is disconnected, then the motor must be isolated from the drive before gaining
access to any live parts.

WARNING
Electrochemical corrosion of grounding terminals
Ensure that grounding terminals are protected against corrosion i.e. as could be caused

The drive must be connected to the system ground of the AC supply. The ground wiring must
conform to local regulations and codes of practice.
For further information on ground cable sizes, refer to Table 2-3
ratings
on page 14.
Protective ground cable
On size 3 and 4, the supply and motor ground connections are made using the M4 studs located
either side of the drive near the plug-in power connectors. See Figure 4-1 and Figure 4-2 for details.
The ground loop impedance must conform to the requirements of local safety regulations.
The drive must be grounded by a connection capable of carrying the prospective fault
current until the protective device (fuse, etc.) disconnects the AC supply.
The ground connections must be inspected and tested at appropriate intervals.
4.2AC Supply requirements
AC supply voltage:
200 V drive: 200 V to 240 V ±10 %
400 V drive: 380 V to 480 V ±10 %
Number of phases: 3
Maximum supply imbalance: 2 % negative phase sequence (equivalent to 3 % voltage imbalance
between phases).
Frequency range: 45 to 66 Hz
For UL compliance only, the maximum supply symmetrical fault current must be limited to 100 kA

4.2.1Supply types
All drives are suitable for use on any supply type i.e TN-S, TN-C-S, TT and IT. 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.
Operation with IT (ungrounded) supplies:
Special attention is required when using internal or external EMC filters with ungrounded
supplies, because in the event of a ground (earth) fault in the motor circuit the drive may
not trip and the filter could be over-stressed. In this case, either the filter must not be
used (removed) or additional independent motor ground fault protection must be
provided. For instructions on removal, refer to Figure 4-11 and Figure 4-12 on page 66.
For details of ground fault protection contact the supplier of the drive.

fault in its own circuit then an input isolating transformer must be provided and if an EMC filter is
required it must be located in the primary circuit. Unusual hazards can occur on ungrounded supplies
with more than one source, for example on ships. Contact the supplier of the drive for more
information.
If an SI-Applications Plus module is installed in the drive, then the drive must not be used
on a corner-grounded or centre-grounded delta supply if the supply voltage is above 300
V. If this is required, please contact the supplier of the drive for more information.
4.2.2Supplies requiring line reactors
Input line reactors reduce the risk of damage to the drive resulting from poor phase balance or
severe disturbances on the supply network.
Where line reactors are to be used, reactance values of approximately 2 % are recommended.
Higher values may be used if necessary, but may result in a loss of drive output (reduced torque at
high speed) because of the voltage drop.
For all drive ratings, 2 % line reactors permit drives to be used with a supply unbalance of up to 3.5 %
negative phase sequence (equivalent to 5% voltage imbalance between phases).
Severe disturbances may be caused by the following factors, for example:
•Power factor correction equipment connected close to the drive.
•Large DC drives having no or inadequate line reactors connected to the supply.
•Across the line (DOL) started motor(s) connected to the supply such that when any of these
motors are started, the voltage dip exceeds 20 %.
Such disturbances may cause excessive peak currents to flow in the input power circuit of the drive.
This may cause nuisance tripping, or in extreme cases, failure of the drive.
Drives of low power rating may also be susceptible to disturbance when connected to supplies with a
high rated capacity.
Line reactors are particularly recommended for use with the following drive models when one of the
above factors exists, or when the supply capacity exceeds 175 kVA:
03200050, 03200066, 03200080, 03200106,
03400025, 03400031, 03400045, 03400062
Model sizes 03400078 to 04400172 have an internal DC choke so they do not require AC line
reactors except for cases of excessive phase unbalance or extreme supply conditions.
When required, each drive must have its own reactor(s). Three individual reactors or a single threephase reactor should be used.
Reactor current ratings
The current rating of the line reactors should be as follows:
Continuous current rating:
Not less than the continuous input current rating of the drive
Repetitive peak current rating:
Not less than twice the continuous input current rating of the drive

4.4DC bus paralleling
DC bus paralleling using standard cable / busbars is supported by all frame sizes.
On frame sizes 3 and 4, terminal and enclosure design enables the DC bus of a number of drives to
be connected together using pre-made busbars. The diagram below shows how the busbar links
connect the DC bus of several drives together.
The connecting of the DC bus between several drives is typically used to:
1. Return energy from a drive which is being overhauled by the load to a second motoring drive.
2. Allow the use of one braking resistor to dissipate regenerative energy from several drives.
There are limitations to the combinations of drives which can be used in this configuration.

The 24 Vdc supply connected to control terminals 1 & 2* provides the following functions:
•It can be used to supplement the drive's own internal 24 V supply when multiple option modules
are being used and the current drawn by these module is greater than the drive can supply.
•It can be used as a back-up power supply to keep the control circuits of the drive powered up
when the line power supply is removed. This allows any fieldbus modules, application modules,
encoders or serial communications to continue to operate.
•It can be used to commission the drive when the line power supply is not available, as the display
operates correctly. However, the drive will be in the Under voltage trip state unless either line
power supply or low voltage DC operation is enabled, therefore diagnostics may not be possible.
(Power down save parameters are not saved when using the 24 V back-up power supply input).
•If the DC bus voltage is too low to run the main SMPS in the drive, then the 24 V supply can be
used to supply all the low voltage power requirements of the drive.

4.6 Low voltage operation
NOTE
WARNING
With the addition of a 24 Vdc power supply to supply the control circuits, the drive is able to operate
from a low voltage DC supply with a range from 24 Vdc to the maximum DC volts.It is possible for
the drive to go from operating on a normal line power supply voltage to operating on a much lower
supply voltage without interruption.
Going from low voltage operation to normal mains operation requires the inrush current to be
controlled. This may be provided externally. If not, the drive supply can be interrupted to utilise the
normal soft starting method in the drive.
To fully exploit the new low voltage mode of operation, the under voltage trip level is now user
programmable. For application data, contact the supplier of the drive.
The working voltage range of the low voltage DC power supply is as follows:

Since capacitance in the motor cable causes loading on the output of the drive, ensure the cable
length does not exceed the values given in Table 5-21 and Table 5-22.
Use 105 °C (221 °F) (UL 60/75 °C temp rise) PVC-insulated cable with copper conductors having a
suitable voltage rating, for the following power connections:
•AC supply to external EMC filter (when used)
•AC supply (or external EMC filter) to drive
•Drive to motor
•Drive to braking resistor
4.9.2High-capacitance / reduced diameter cables
The maximum cable length is reduced from that shown in Table 5-21 and Table 5-22 if high
capacitance or reduced diameter motor cables are used.
Most cables have an insulating jacket between the cores and the armor or shield; these cables have
a low capacitance and are recommended. Cables that do not have an insulating jacket tend to have
high capacitance; if a cable of this type is used, the maximum cable length is half that quoted in the

4.9.3Motor winding voltage
The PWM output voltage can adversely affect the inter-turn insulation in the motor. This is because of
the high rate of change of voltage, in conjunction with the impedance of the motor cable and the
distributed nature of the motor winding.
For normal operation with AC supplies up to 500 Vac and a standard motor with a good quality
insulation system, there is no need for any special precautions. In case of doubt the motor supplier
should be consulted. Special precautions are recommended under the following conditions, but only
if the motor cable length exceeds 10 m:
•Operation of 400 V drive with continuous or very frequent sustained braking
•Multiple motors connected to a single drive
For multiple motors, the precautions given in section 4.9.4
For the other cases listed, it is recommended that an inverter-rated motor be used taking into
account the voltage rating of the inverter. This has a reinforced insulation system intended by the
manufacturer for repetitive fast-rising pulsed voltage operation.
Users of 575 V NEMA rated motors should note that the specification for inverter-rated motors given
in NEMA MG1 section 31 is sufficient for motoring operation but not where the motor spends
significant periods braking. In that case an insulation peak voltage rating of 2.2 kV is recommended.
If it is not practical to use an inverter-rated motor, an output choke (inductor) should be used. The
recommended type is a simple iron-cored component with a reactance of about 2 %. The exact value
is not critical. This operates in conjunction with the capacitance of the motor cable to increase the
rise-time of the motor terminal voltage and prevent excessive electrical stress.
Multiple motors

however, variations on this are common e.g. 690 V ∆ 400 V.
Incorrect connection of the windings will cause severe under or over fluxing of the motor, leading to a
very poor output torque or motor saturation and overheating respectively.
4.9.6Output contactor
If the cable between the drive and the motor is to be interrupted by a contactor or circuit
breaker, ensure that the drive is disabled before the contactor or circuit breaker is opened
or closed. Severe arcing may occur if this circuit is interrupted with the motor running at
high current and low speed.
A contactor is sometimes required to be installed between the drive and motor for safety purposes.
The recommended motor contactor is the AC3 type.
Switching of an output contactor should only occur when the output of the drive is disabled.
Opening or closing of the contactor with the drive enabled will lead to:
1. OI ac trips (which cannot be reset for 10 seconds)
2. High levels of radio frequency noise emission
3. Increased contactor wear and tear
The Drive Enable terminal when opened provides a Safe Torque Off function. This can in many
cases replace output contactors.
For further information see the
Control User Guide
.
4.10 Braking
Braking occurs when the drive is decelerating the motor, or is preventing the motor from gaining
speed due to mechanical influences. During braking, energy is returned to the drive from the motor.
When motor braking is applied by the drive, the maximum regenerated power that the drive can
absorb is equal to the power dissipation (losses) of the drive.
When the regenerated power is likely to exceed these losses, the DC bus voltage of the drive
increases. Under default conditions, the drive brakes the motor under PI control, which extends the
deceleration time as necessary in order to prevent the DC bus voltage from rising above a user
defined set-point.
If the drive is expected to rapidly decelerate a load, or to hold back an overhauling load, a braking
resistor must be installed.
Table 4-5 shows the default DC voltage level at which the drive turns on the braking transistor.
However the braking resistor turn on and the turn off voltages are programmable with

Overload protection
When an external braking resistor is used, it is essential that an overload protection device
is incorporated in the braking resistor circuit; this is described in
When a braking resistor is to be mounted outside the enclosure, ensure that it is mounted in a
ventilated metal housing that will perform the following functions:
•Prevent inadvertent contact with the resistor
•Allow adequate ventilation for the resistor
When compliance with EMC emission standards is required, external connection requires the cable
to be armored or shielded, since it is not fully contained in a metal enclosure. See section
4.12.5
Compliance with generic emission standards
on page 70 for further details.
Internal connection does not require the cable to be armored or shielded.

For high-inertia loads or under continuous braking, the continuous power dissipated in the braking
resistor may be as high as the power rating of the drive. The total energy dissipated in the braking
resistor is dependent on the amount of energy to be extracted from the load.
The instantaneous power rating refers to the short-term maximum power dissipated during the on
intervals of the pulse width modulated braking control cycle. The braking resistor must be able to
withstand this dissipation for short intervals (milliseconds). Higher resistance values require
proportionately lower instantaneous power ratings.
In most applications, braking occurs only occasionally. This allows the continuous power rating of the
braking resistor to be much lower than the power rating of the drive. It is therefore essential that the
instantaneous power rating and energy rating of the braking resistor are sufficient for the most
extreme braking duty that is likely to be encountered.
Optimization of the braking resistor requires careful consideration of the braking duty.
Select a value of resistance for the braking resistor that is not less than the specified minimum
resistance. Larger resistance values may give a cost saving, as well as a safety benefit in the event
of a fault in the braking system. Braking capability will then be reduced, which could cause the drive
to trip during braking if the value chosen is too large.
The following external brake resistors are available from the supplier of the drive for sizes 3 and 4.

4.11.1Use of residual current device (RCD)
WARNING
There are three common types of ELCB / RCD:
1. AC - detects AC fault currents
2. A - detects AC and pulsating DC fault currents (provided the DC current reaches zero at least
once every half cycle)
3. B - detects AC, pulsating DC and smooth DC fault currents
•Type AC should never be used with drives.
•Type A can only be used with single phase drives
•Type B must be used with three phase drives
Only type B ELCB / RCD are suitable for use with 3 phase inverter drives.
If an external EMC filter is used, a delay of at least 50 ms should be incorporated to ensure spurious
trips are not seen. The leakage current is likely to exceed the trip level if all of the phases are not
energized simultaneously.
4.12EMC (Electromagnetic compatibility)
The requirements for EMC are divided into three levels in the following three sections:
•section 4.12.3, General requirements for EMC, this is for all applications, to ensure reliable
operation of the drive and minimise the risk of disturbing nearby equipment. The immunity
standards specified in Chapter 5.1.25
met, but no specific emission standards are applied.
•section 4.12.4, Requirements for meeting the EMC standard for power drive systems, IEC618003 (EN 61800-3:2004).
•section 4.12.5, Requirements for meeting the generic emission standards for the industrial
environment, IEC61000-6-4, EN 61000-6-4:2007.
The recommendations of section 4.12.3 will usually be sufficient to avoid causing disturbance to
adjacent equipment of industrial quality. If particularly sensitive equipment is to be used nearby, or in
a non-industrial environment, then the recommendations of section 4.12.4 or section 4.12.5 should
be followed to give reduced radio-frequency emission.
In order to ensure the installation meets the various emission standards described in:
•The EMC data sheet available from the supplier of the drive
•The Declaration of Conformity at the front of this manual

High ground leakage current
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 EMC
filter.
The installer of the drive is responsible for ensuring compliance with the EMC regulations
that apply in the country in which the drive is to be used.
4.12.1Grounding hardware
The drive is supplied with a grounding bracket and grounding clamp to facilitate EMC compliance.
They provide a convenient method for direct grounding of cable shields without the use of "pig-tails”.
Cable shields can be bared and clamped to the grounding bracket using metal clips or clamps1 (not
supplied) or cable ties. Note that the shield must in all cases be continued through the clamp to the
intended terminal on the drive, in accordance with the connection details for the specific signal.
1
A suitable clamp is the Phoenix DIN rail mounted SK14 cable clamp (for cables with a maximum
outer diameter of 14 mm).
•See Figure 4-9 for details on installing the grounding clamp.
•See Figure 4-10 for details on installing the grounding bracket.
Figure 4-9 Installation of grounding clamp (size 3 and 4)
Loosen the ground connection nuts and slide the grounding clamp in the direction shown. Once in
place, the ground connection nuts should be tightened with a maximum torque of 2 N m (1.47 lb ft).

Unidrive M/HS Frame 3 and 4 Power Installation Guide
Loosen the ground connection nuts and slide the grounding bracket in the direction shown. Once in

On size 3 and 4 the grounding bracket is secured using the power ground terminal of the
drive. Ensure that the supply ground connection is secure after installing / removing the
grounding bracket. Failure to do so will result in the drive not being grounded.
A faston tab is located on the grounding bracket for the purpose of connecting the drive 0 V to ground
should the user require to do so.
4.12.2 Internal EMC filter
It is recommended that the internal EMC filter be kept in place unless there is a specific reason for
removing it.
If the drive is used with ungrounded (IT) supplies, the internal EMC filter must be
removed unless additional motor ground fault protection is installed.
For instructions on removal refer to section 4.12.2. For details of ground fault protection
contact the supplier of the drive.
If the drive is used as a motoring drive as part of a regen system, then the internal EMC filter must be
removed.
The internal EMC filter reduces radio-frequency emission into the line power supply. Where the
motor cable is short, it permits the requirements of EN 61800-3:2004 to be met for the second
environment - see section 4.12.4

longer motor cables the filter continues to provide a useful reduction in emission levels, and when
used with any length of shielded motor cable up to the limit for the drive, it is unlikely that nearby
industrial equipment will be disturbed. It is recommended that the filter be used in all applications
unless the instructions given above require it to be removed, or where the ground leakage current of
28 mA for size 3 is unacceptable. See section 4.12.2 for details of removing and installing the internal
EMC filter.

CAUTION

Systems)
Meeting the requirements of this standard depends on the environment that the drive is intended to
operate in, as follows:
Operation in the first environment
Observe the guidelines given in section 4.12.5
page 70. An external EMC filter will always be required.
This is a product of the restricted distribution class according to IEC 61800-3
In a residential environment this product may cause radio interference in which case the
user may be required to take adequate measures.
Operation in the second environment
In all cases a shielded motor cable must be used, and an EMC filter is required for all drives with a
rated input current of less than 100 A.
The drive contains an in-built filter for basic emission control. In some cases feeding the motor cables
(U, V and W) once through a ferrite ring can maintain compliance for longer cable lengths.
For longer motor cables, an external filter is required. Where a filter is required, follow the guidelines
in section 4.12.5
Compliance with generic emission standards
Where a filter is not required, follow the guidelines given in section 4.12.3
EMC Ground (earth) connections
on page 67.
The second environment typically includes an industrial low-voltage power supply network
which does not supply buildings used for residential purposes. Operating the drive in this
environment without an external EMC filter may cause interference to nearby electronic
equipment whose sensitivity has not been appreciated. The user must take remedial
measures if this situation arises. If the consequences of unexpected disturbances are
severe, it is recommended that the guidelines in section 4.12.5
compliance with EMC standards and definitions of environments.

From an EMC consideration it is irrelevant whether the motor cable contains an internal (safety)
ground core, or if there is a separate external ground conductor, or where grounding is through the
shield alone. An internal ground core will carry a high noise current and therefore it must be
terminated as close as possible to the shield termination.
Unshielded wiring to the optional braking resistor(s) may be used provided the wiring runs internally to
the enclosure. Ensure a minimum spacing of 300 mm (12 in) from the signal wiring and the AC supply

Interruptions to the motor cable
The motor cable should ideally be a single length of shielded or armored cable having no
interruptions. In some situations it may be necessary to interrupt the cable, as in the following
examples:
•Connecting the motor cable to a terminal block in the drive enclosure
•Installing a motor isolator / disconnect switch for safety when work is done on the motor
In these cases the following guidelines should be followed.
Terminal block in the enclosure
The motor cable shields should be bonded to the back-plate using uninsulated metal cable-clamps
which should be positioned as close as possible to the terminal block. Keep the length of power
conductors to a minimum and ensure that all sensitive equipment and circuits are at least 0.3 m (12
in) away from the terminal block.
Figure 4-21 Connecting the motor cable to a terminal block in the enclosure
The motor cable shields should be connected by a very short conductor having a low inductance.
The use of a flat metal coupling-bar is recommended; conventional wire is not suitable.
The shields should be bonded directly to the coupling-bar using uninsulated metal cable-clamps.
Keep the length of the exposed power conductors to a minimum and ensure that all sensitive
equipment and circuits are at least 0.3 m (12 in) away.
The coupling-bar may be grounded to a known low-impedance ground nearby, for example a large
metallic structure which is connected closely to the drive ground.

The input/output ports for the control circuits are designed for general use within machines and small
systems without any special precautions.
These circuits meet the requirements of EN 61000-6-2:2005 (1 kV surge) provided the 0 V
connection is not grounded.
In applications where they may be exposed to high-energy voltage surges, some special measures
may be required to prevent malfunction or damage. Surges may be caused by lightning or severe
power faults in association with grounding arrangements which permit high transient voltages
between nominally grounded points. This is a particular risk where the circuits extend outside the
protection of a building.
As a general rule, if the circuits are to pass outside the building where the drive is located, or if cable
runs within a building exceed 30 m, some additional precautions are advisable. One of the following
techniques should be used:
1. Galvanic isolation, i.e. do not connect the control 0 V terminal to ground. Avoid loops in the
control wiring, i.e. ensure every control wire is accompanied by its return (0 V) wire.
2. Shielded cable with additional power ground bonding. The cable shield may be connected to
ground at both ends, but in addition the ground conductors at both ends of the cable must be
bonded together by a power ground cable (equipotential bonding cable) with cross-sectional
area of at least 10 mm2, or 10 times the area of the signal cable shield, or to suit the electrical
safety requirements of the plant. This ensures that fault or surge current passes mainly through
the ground cable and not in the signal cable shield. If the building or plant has a well-designed
common bonded network this precaution is not necessary.
3. Additional over-voltage suppression - for the analog and digital inputs and outputs, a zener diode
network or a commercially available surge suppressor may be connected in parallel with the
input circuit as shown in Figure 4-23 and Figure 4-24.
If a digital port experiences a severe surge its protective trip may operate (I/O Overload trip). For
continued operation after such an event, the trip can be reset automatically by setting Pr
10.034
to 5.

Surge suppression devices are available as rail-mounting modules, e.g. from Phoenix Contact:
Unipolar TT-UKK5-D/24 DC

These devices are not suitable for encoder signals or fast digital data networks because the
capacitance of the diodes adversely affects the signal. Most encoders have galvanic isolation of the
signal circuit from the motor frame, in which case no precautions are required. For data networks,
follow the specific recommendations for the particular network.

400 V drive: 380 V to 480 V ±10 %
Number of phases: 3
Maximum supply imbalance: 2 % negative phase sequence (equivalent to 3 % voltage imbalance
between phases).
Frequency range: 45 to 66 Hz
For UL compliance only, the maximum supply symmetrical fault current must be limited to 100 kA
5.1.6Line reactors
Input line reactors reduce the risk of damage to the drive resulting from poor phase balance or
severe disturbances on the supply network.
Where line reactors are to be used, reactance values of approximately 2 % are recommended.
Higher values may be used if necessary, but may result in a loss of drive output (reduced torque at
high speed) because of the voltage drop.
For all drive ratings, 2 % line reactors permit drives to be used with a supply unbalance of up to 3.5 %
negative phase sequence (equivalent to 5% voltage imbalance between phases).
Severe disturbances may be caused by the following factors, for example:
•Power factor correction equipment connected close to the drive.
•Large DC drives having no or inadequate line reactors connected to the supply.
•Across the line (DOL) started motor(s) connected to the supply such that when any of these
motors are started, the voltage dip exceeds 20 %.
Such disturbances may cause excessive peak currents to flow in the input power circuit of the drive.
This may cause nuisance tripping, or in extreme cases, failure of the drive.
Drives of low power rating may also be susceptible to disturbance when connected to supplies with a
high rated capacity.
Line reactors are particularly recommended for use with the following drive models when one of the
above factors exists, or when the supply capacity exceeds 175 kVA:
03200050, 03200066, 03200080, 03200106,
03400025, 03400031, 03400045, 03400062
Model sizes 03400078 to 04400172 have an internal DC choke so they do not require AC line
reactors except for cases of excessive phase unbalance or extreme supply conditions.
When required, each drive must have its own reactor(s). Three individual reactors or a single threephase reactor should be used.
Reactor current ratings
The current rating of the line reactors should be as follows:
Continuous current rating:
Not less than the continuous input current rating of the drive
Repetitive peak current rating:
Not less than twice the continuous input current rating of the drive

5.1.8Storage
-40 °C (-40 °F) to +55 °C (131 °F) for long term storage, or to +70 °C (158 °F) for short term
storage.
Storage time is 2 years.
Electrolytic capacitors in any electronic product have a storage period after which they require
reforming or replacing.
The DC bus capacitors have a storage period of 10 years.
The low voltage capacitors on the control supplies typically have a storage period of 2 years and are
thus the limiting factor.
Low voltage capacitors cannot be reformed due to their location in the circuit and thus may require
replacing if the drive is stored for a period of 2 years or greater without power being applied.
It is therefore recommended that drives are powered up for a minimum of 1 hour after every 2 years
of storage. This process allows the drive to be stored for a further 2 years.
5.1.9Altitude
Altitude range: 0 to 3,000 m (9,900 ft), subject to the following conditions:
1,000 m to 3,000 m (3,300 ft to 9,900 ft) above sea level: de-rate the maximum output current from
the specified figure by 1% per 100 m (330 ft) above 1,000 m (3,300 ft)
For example at 3,000 m (9,900 ft) the output current of the drive would have to be de-rated by 20 %.

Unidrive Mxxx models:
In all operating modes (Open loop, RFC-A, RFC-S) the maximum output frequency is limited to 550
Hz.
Unidrive HSxx models:
In open loop mode the maximum achievable output frequency is 3,000 Hz.
In RFC-A and RFC-S modes, the maximum achievable output frequency is 1,250Hz.
In RFC-S mode the speed is also limited by the voltage constant (Ke) of the motor unless field
weakening operation is enabled. Ke is a specific constant for the servo motor being used. It can
normally be found on the motor data sheet in V/k rpm (volts per 1,000 rpm).
It is recommended that a minimum ratio of 12:1 is maintained between the switching frequency and
the maximum output frequency to maintain the quality of the output waveform. If this minimum ratio is
exceeded, extra motor losses will result due to the increased harmonic content of the output
waveform.
5.1.17
Speed:
The absolute frequency and speed accuracy depends on the accuracy of the crystal used with the
drive microprocessor. The accuracy of the crystal is 100 ppm, and so the absolute frequency/speed
accuracy is 100 ppm (0.01 %) of the reference, when a preset speed is used. If an analog input is
used the absolute accuracy is further limited by the absolute accuracy of the analog input.
The following data applies to the drive only; it does not include the performance of the source of the
control signals.

The heatsink fan generates the majority of the sound pressure level at 1 m produced by the drive. The
heatsink fan is a variable speed fan. The drive controls the speed at which the fan runs based on the
temperature of the heatsink and the drive's thermal model system.
Table 5-13 gives the sound pressure level at 1 m produced by the drive when running at maximum
normal and heavy duty current and when the heatsink fan is running at minimum speed.

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 fault current given in Table 5-16.
