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.

1Safety information
WARNING
CAUTION
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.

1.6Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided.
For further information, refer to section 3.2.5 Fire protection on page 17.
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.
2014/30/EU: Electromagnetic Compatibility Directive.
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 00.006 motor rated current. This affects the
thermal protection of the motor.
1.9Mechanical 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.
1.10Adjusting 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.

2.3.1Typical 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 Parameter Reference Guide.
Typical values are shown in the table below for RFC-A and open loop (OL) modes:

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.

3.1Safety information
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:
•High IP as standard
•Enclosure sizing and layout
•Terminal location and torque settings
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 Planning the installation
The following considerations must be made when planning the installation:
3.2.1Access
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.
16
Unidrive M100 to M400 Frame 1 to 4 Power Installation Guide
Issue Number: 1
3.2.2Environmental protection
NOTE
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.
3.2.3Cooling
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 3.5.1
Enclosure sizing
on page 24.
3.2.4Electrical safety
The installation must be safe under normal and fault conditions. Electrical installation instructions are
given in Chapter 4
Electrical installation on page 37
.
3.2.5Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided.
For installation in the USA, a NEMA 12 enclosure is suitable.
For installation outside the USA, the following (based on IEC 62109-1, standard for PV inverters) is
recommended.
Enclosure can be metal and/or polymeric, polymer must meet requirements which can be
summarized for larger enclosures as using materials meeting at least UL 94 class 5VB at the point of
minimum thickness.
Air filter assemblies to be at least class V-2.
The location and size of the bottom shall cover the area shown in Figure 3-1. Any part of the side
which is within the area traced out by the 5° angle is also considered to be part of the bottom of the
fire enclosure.

The bottom, including the part of the side considered to be part of the bottom, must be designed to
prevent escape of burning material - either by having no openings or by having a baffle construction.
This means that openings for cables etc. must be sealed with materials meeting the 5VB
requirement, or else have a baffle above. See Figure 3-2 for acceptable baffle construction. This
does not apply for mounting in an enclosed electrical operating area (restricted access) with concrete
floor.

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 4.7
(Electromagnetic compatibility) on page 61
.
EMC
3.2.7Hazardous 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.

NOTE
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.
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 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.

A minimum clearance of 100 mm above and below Frame 01 to 04 products is required
for applications where the product is subjected to rated load and rated ambient
temperature.
* A minimum clearance of 50 mm above and below Frame 01 to 04 products is permissible
in applications where either the ambient operating temperature is 35 °C or less or the
average output current is derated by 20 %.
Derating for reduced clearances is to be applied in addition to the derating for increased
switching frequency if operating above 3 kHz.
We recommend that cables are routed carefully to ensure that the airflow in and out of the
product is not impeded, when using the reduced clearances.
If DIN rail mounting is used in an installation where the drive is to be subjected to shock
or vibration, it is recommended that the bottom mounting screws are used to secure the
drive to the back-plate. If the installation is going to be subjected to heavy shock or
vibration, then it is recommended that the drive is surface mounted rather than DIN rail
mounted.

The DIN rail mounting mechanism has been designed so no tools are required to install
and remove the drive from a DIN rail. Please ensure the top mounting lugs are located
correctly on the DIN rail before installation is initiated. The DIN rail used should conform

2. If an external EMC filter is to be used with each drive, add the dissipation figures from section
5.2.1

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.

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 from the supplier of the material). If in any doubt, allow for a greater margin in the
temperature rise.

3.5.2Enclosure 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.
The ambient temperature for the four different combinations is defined below:
1. Totally enclosed with no air flow (<2 m/s) over the drive T

3.6 Heatsink fan operation
The drive is ventilated by an internal heatsink fan. The fan channels air through the heatsink
chamber.
Ensure the minimum clearances around the drive are maintained to allow air to flow freely.
The heatsink fan on all drive sizes is a variable speed fan (except for size 1 which has a single 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
06.045
. This could incur an output current derating.

Many cable management features have been incorporated into the product and accessories, this
chapter shows how to optimize them. Key features include:
•Internal EMC filter
•EMC compliance with shielding / grounding accessories
•Product rating, fusing and cabling information
•Brake resistor details (selection / ratings)
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.
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.
Equipment supplied by plug and socket
Special attention must be given if the drive is installed in equipment which is connected to
the AC supply by a plug and socket. The AC supply terminals of the drive are 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).

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 i.e. removed, or additional independent motor ground fault protection must be
provided.
For instructions on removal, refer toFigure 4-13
filter
on page 64 to Figure 4-16
details of ground fault protection contact the supplier of the drive.
A ground fault in the supply has no effect in any case. If the motor must continue to run with a ground
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

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.

Model sizes 04200133 to 04400170 have an internal DC choke so they do not require AC line
reactors except for cases of excessive phase unbalance or extreme supply conditions.

4.4.2High-capacitance / reduced diameter cables
The maximum cable length is reduced from that shown in section 4.4.1
page 52, 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
tables, (Figure 4-8 shows how to identify the two types).
Figure 4-8 Cable construction influencing the capacitance
The maximum motor cable lengths specified in section 4.4.1
Cable types and lengths
on page 52 is
shielded and contains four cores. Typical capacitance for this type of cable is 130 pF/m (i.e. from one
core to all others and the shield connected together).
4.4.3 Motor 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:
•AC supply voltage exceeds 500 V
•DC supply voltage exceeds 670 V (i.e. Regenerative / AFE supply)
•Operation of 400 V drive with continuous or very frequent sustained braking

For multiple motors, the precautions given in section 4.4.4
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.
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
should be followed.
4.4.4Multiple motors

If the drive is to control more than one motor, one of the fixed V/F modes should be selected

= Fixed or Squared). Make the motor connections as shown in Figure 4-9 and Figure 4-
10. The maximum cable lengths in Table 4-11 to Table 4-13 apply to the sum of the total cable
lengths from the drive to each motor.
It is recommended that each motor is connected through a protection relay since the drive cannot
protect each motor individually. For connection, a sinusoidal filter or an output inductor must be
connected as shown in Figure 4-10, even when the cable lengths are less than the maximum
permissible. For high DC voltages or when supplied by a regen system, a sinusoidal filter is
recommended. For details of filter or inductor sizes refer to the supplier of the drive.

The voltage rating for and ∆ connections of the motor should always be checked before
attempting to run the motor.
The default setting of the motor rated voltage parameter is the same as the drive rated voltage, i.e.
400 V drive 400 V rated voltage
230 V drive 230 V rated voltage
A typical 3 phase motor would be connected in for 400 V operation or ∆ for 230 V operation,
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

WARNING
WARNING
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 (Unidrive M300/M400
only). This can in many cases replace output contactors.
For further information see the
Control User Guide

4.5Braking
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 4-14 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

WARNING
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 Figure 4-11 on page 59
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

Compliance with generic emission standards
Internal connection does not require the cable to be armored or shielded.

* Resistor tolerance: ±10 %
For high-inertia loads or under continuous braking, the
resistor may be as high as the power rating of the drive. The total
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.
Thermal protection circuit for the braking resistor
The thermal protection circuit must disconnect the AC supply from the drive if the resistor becomes
overloaded due to a fault. Figure 4-11 shows a typical circuit arrangement.

The above leakage currents are just the leakage currents of the drive with the internal
EMC filter connected and do not take into account any leakage currents of the motor or

When the internal filter is installed the leakage current is high. In this case a permanent
fixed ground connection must be provided, or other suitable measures taken to prevent a
safety hazard occurring if the connection is lost.

provided using two independent conductors each with a cross-section equal to or
exceeding that of the supply conductors. The drive is provided with two ground
connections to facilitate this. Both ground connections are necessary to meet EN 618005-1: 2007.
4.6.1Use of residual current device (RCD)
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 with an ELCB / RCD, 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.

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.
4.7.1Grounding hardware
The drive is supplied with a grounding bracket / clamp to facilitate EMC compliance. This provides 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.

A suitable clamp is the Phoenix DIN rail mounted SK14 cable clamp (for cables with a maximum
outer diameter of 14 mm).
See Figure 4-12 for details regarding the installation of the grounding bracket.

4.7.2Internal EMC filter and line to ground varistors (MOVs)
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 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+A1:2012 to be met for the
second environment - see section 4.7.4
standard for Power Drive Systems)
(EMC)
on page 93. For 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 is unacceptable. As shown in Figure 4-13 to Figure 4-16, the internal EMC filter is
removed by removing the screw (1).
Compliance with IEC 61800-3 (EN 61800-3:2004+A1:2012
The supply must be disconnected before removing the internal EMC filter.
The line to ground varistors should only be removed in special circumstances such as
ungrounded supplies with more than one source, for example on ships. Where the line to
ground varistors are removed, ensure that line to ground transients are limited to values
of category II. This is to ensure that line to ground transients do not exceed 4 kV as the
drive insulation system from power to ground is designed to category II.Contact the
supplier of the drive for more information.

CAUTION
Power Drive 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 4.7.5
page 69. An external EMC filter will always be required.
This is a product of the restricted distribution class according to EN 618003:2004+A1:2012
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 4.7.5
Compliance with generic emission standards
Where a filter is not required, follow the guidelines given in section 4.7.3
EMC
on page 65.
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 4.7.5

Connect the shield of the motor cable to the ground terminal of the motor frame using a
link that is as short as possible and not exceeding 50 mm (2 in) long.
A complete 360° termination of the shield to the terminal housing of the motor is
beneficial.
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.

4.7.6Variations in the EMC wiring
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 4-25 Connecting the motor cable to a terminal block in the enclosure
Using a motor isolator / disconnect-switch
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.

Surge immunity of control circuits - long cables and connections outside a building
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 4-27 and Figure 4-28.
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

to 5.

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.

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: Size 1 to 3
Model sizes 04200133 to 04400170 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
The recommended AC line reactors are shown in section 4.2.4

5.1.6 Temperature, humidity and cooling method
Size 1 to 4:
Ambient temperature operating range:
- 20 °C to 60 °C (- 4 °F to 140 °F).
Output current derating must be applied at ambient temperatures >40 °C (104 °F).
Cooling method: Forced convection
Maximum humidity: 95 % non-condensing at 40 °C (104 °F)
5.1.7Storage
Size 1 to 4:
-40 °C (-40 °F) to +60 °C (140 °F) for long 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.
5.1.8 Altitude
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 %.
5.1.9 IP / UL Rating
The drive is rated to IP20 pollution degree 2 (non-conductive contamination only).
In addition to this, drives are rated to IP21 standard (without an Adaptor Interface module installed).
The IP rating of a product is a measure of protection against ingress and contact to foreign bodies
and water. It is stated as IP XX, where the two digits (XX) indicate the degree of protection provided
as shown in Table 5-5.

Unidrive HS30 models:
In open loop mode only, the maximum achievable output frequency is 3,000 Hz.
5.1.16Accuracy and resolution
Frequency:
The absolute frequency accuracy depends on the accuracy of the oscillator used with the drive
microprocessor. The accuracy of the oscillator is ± 0.02 %, and so the absolute frequency accuracy
is ± 0.02 % of the reference, when a preset frequency 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.
Open & closed loop resolution:
Preset frequency reference: 0.01 Hz
Analog input 1: 11 bit plus sign
Analog input 2: 11 bit

The resolution of the current feedback is 10 bit plus sign.
Accuracy: typical 2 %

5.1.17Acoustic noise
The heatsink fan generates the majority of the sound produced by the drive. The heatsink fan on all
drives is a variable speed fan (except size 1, which is a single 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 5-7 gives the sound pressure level at 1 m produced by the drive for the heatsink fan running at
the maximum and minimum speeds.

* Resistor tolerance: ±10 %
For high-inertia loads or under continuous braking, the
resistor may be as high as the power rating of the drive. The total
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.

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.
Residential generic standard EN 61000-6-3:2007+A1:2011
EN 61800-3:2004+A1:2012 first environment unrestricted distribution
EN 61800-3:2004+A1:2012 defines the following:
•The first environment is one that includes residential premises. It also includes establishments
directly connected without intermediate transformers to a low-voltage power supply network
which supplies buildings used for residential purposes. The second environment is one that
includes all establishments other than those directly connected to a low-voltage power supply
network which supplies buildings used for residential purposes.
•Restricted distribution is defined as a mode of sales distribution in which the manufacturer
restricts the supply of equipment to suppliers, customers or users who separately or jointly have
technical competence in the EMC requirements of the application of drives.
IEC 61800-3:2004 and EN 61800-3:2004+A1:2012
The 2004 revision of the standard uses different terminology to align the requirements of the
standard better with the EC EMC Directive.

6.6Electrical Installation
TERMINAL TORQUE
Terminals must be tightened to the rated torque as specified in the Installation Instructions. Refer to
section 3.8.1 Terminal sizes and torque settings on page 34 for further information.
WIRING TERMINALS
Drives must be installed using cables rated for 75 °C operation, copper wire only.
UL Listed closed-loop connectors sized according to the field wiring shall be used for all field wiring
connections. Refer to section 4.1.2 Ground connections on page 42 for further information.
BRANCH CIRCUIT PROTECTION
The fuses and circuit breakers required for branch circuit protection are contained in the Installation
Instructions. Refer to section 4.3 Ratings on page 47 for further information.
OPENING OF BRANCH CIRCUIT
Opening of the branch-circuit protective device may be an indication that a fault has been
interrupted. To reduce the risk of fire or electric shock, the equipment should be examined and
replaced if damaged. If burnout of the current element of an overload relay occurs, the complete
overload relay must be replaced.
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit
protection must be provided in accordance with the National Electrical Code and any additional local
"codes".
DYNAMIC BRAKING
Drives with model numbers beginning M100, M101, M200, M201, M300 or M400 have been
evaluated for dynamic braking applications.
6.7Motor overload protection and thermal memory retention
All drives incorporate internal overload protection for the motor load that does not require the use of
an external or remote overload protection device.
The protection level is adjustable and the method of adjustment is provided in the Control User Guide. Maximum current overload is dependent on the values entered into the current limit
parameters (motoring current limit, regenerative current limit and symmetrical current limit entered as
percentage) and the motor rated current parameter (entered in amperes).
The duration of the overload is dependent on motor thermal time constant. The time constant is
programmable. The default overload protection is typically set to 150 % of the motor rated current for
120 seconds.
The drives are provided with user terminals that can be connected to a motor thermistor to protect
the motor from high temperature, in the event of a motor cooling fan failure.
The method of adjustment of the overload protection is provided in the Installation Instructions
shipped with the product.
All models are provided with thermal memory retention.
