General Information
This guide covers the basic information that is required to install the drive, in applications where a drive malfunction does not result in a mechanical hazard. When the drive is used in a safety related application, i.e. where a malfunction might result in a hazard, it is essential to refer to this guide and the Control User Guide. The Control User Guide is available for download from: http://www.emersonindustrial.com/en-EN/controltechniques/downloads/userguidesandsoftware/Pages/downloads.aspx or www.emersonindustrial.com/en-EN/leroy-somer-motors-drives/downloads/Pages/manuals.aspx The manufacturer accepts no liability for any consequences resulting from inappropriate, negligent or incorrect installation or adjustment of the optional operating parameters of the equipment or from mismatching the variable speed drive with the motor. The contents of this guide are believed to be correct at the time of printing. In the interests of a commitment to a policy of continuous development and improvement, the manufacturer reserves the right to change the specification of the product or its performance, or the contents of the guide, without notice. All rights reserved.

This product is supplied with the latest firmware version. If this drive is to be connected to an existing system or machine, all drive firmware versions should be verified to confirm the same functionality as drives of the same model already present. This may also apply to drives returned from an Emerson Industrial Automation Service Centre or Repair Centre. If there is any doubt please contact the supplier of the product. The firmware version of the drive can be checked by looking at Pr 11.029
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.
REACH legislation
EC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of Chemicals (REACH) requires the supplier of an article to inform the recipient if it contains more than a specified proportion of any substance which is considered by the European Chemicals Agency (ECHA) to be a Substance of Very High Concern (SVHC) and is therefore listed by them as a candidate for compulsory authorisation. For current information on how this requirement applies in relation to specific Emerson Industrial Automation’s products, please approach your usual contact in the first instance.

1 Safety information

WARNING
CAUT ION
NOTE

1.1 Warnings, Cautions and Notes

A Warning contains information which is essential for avoiding a safety hazard.
A Caution contains information which is necessary for avoiding a risk of damage to the product or other equipment.
A Note contains information, which helps to ensure correct operation of the product.

1.2 Electrical safety - general warning

The voltages used in the drive can cause severe electrical shock and/or burns, and could be lethal. Extreme care is necessary at all times when working with or adjacent to the drive. Specific warnings are given at the relevant places in this guide.

1.3 System design and safety of personnel

The drive is intended as a component for professional incorporation into complete equipment or a system. If installed incorrectly, the drive may present a safety hazard.
The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control equipment which can cause injury.
Close attention is required to the electrical installation and the system design to avoid hazards either in normal operation or in the event of equipment malfunction. System design, installation, commissioning/start-up and maintenance must be carried out by personnel who have the necessary training and experience. They must read this safety information and this Power Installation Guide carefully.
The STOP and Safe Torque Off functions of the drive do not isolate dangerous voltages from the output of the drive or from any external option unit. The supply must be disconnected by an approved electrical isolation device before gaining access to the electrical connections.
With the sole exception of the Safe Torque Off function, none of the drive functions must be used to ensure safety of personnel, i.e. they must not be used for safety-related functions.
Careful consideration must be given to the functions of the drive which might result in a hazard, either through their intended behavior or through incorrect operation due to a fault. In any application where a malfunction of the drive or its control system could lead to or allow damage, loss or injury, a risk analysis must be carried out, and where necessary, further measures taken to reduce the risk ­for example, an over-speed protection device in case of failure of the speed control, or a fail-safe mechanical brake in case of loss of motor braking.
The Safe Torque Off function may be used in a safety-related application. The system designer is responsible for ensuring that the complete system is safe and designed correctly according to the relevant safety standards.

1.4 Environmental limits

Instructions in 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.

1.5 Access

Drive access must be restricted to authorized personnel only. Safety regulations which apply at the place of use must be complied with.
Safety information

1.6 Fire protection

The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided. For further information, refer to the section 3.2.5 Fire protection on page 18.

1.7 Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national wiring regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations. Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses or other protection, and protective ground (earth) connections.
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:
Safety of Machinery 2006/42/EC Electromagnetic Compatibility (EMC) Directive 2014/30/EU

1.8 Motor

Ensure the motor is installed in accordance with the manufacturer’s recommendations. Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is intended to use the capability of the drive to run a motor at speeds above its designed maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less effective. The motor should be installed with a protection thermistor. If necessary, an electric forced vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor. The default values in the drive should not be relied upon.
It is essential that the correct value is entered in Pr 00.046 motor rated current. This affects the thermal protection of the motor.
Product information Mechanical installation Electrical installation Technical data UL listing information

1.9 Mechanical brake control

The brake control functions are provided to allow well co-ordinated operation of an external brake with the drive. While both hardware and software are designed to high standards of quality and robustness, they are not intended for use as safety functions, i.e. where a fault or failure would result in a risk of injury. In any application where the incorrect operation of the brake release mechanism could result in injury, independent protection devices of proven integrity must also be incorporated.

1.10 Adjusting parameters

Some parameters have a profound effect on the operation of the drive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering.
Unidrive M/HS Frame 11E Power Installation Guide 9 Issue Number: 2

1.11 Electrical installation

1.11.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may be lethal:
AC supply cables and connections
Output cables and connections
Many internal parts of the drive, and external option units Unless otherwise indicated, control terminals are single insulated and must not be touched.
1.11.2 Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the AC supply has been disconnected. If the drive has been energized, the AC supply must be isolated at least ten minutes before work may continue.

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 2-5 Typical overload limits
Operating mode RFC from cold RFC from 100 %
Normal Duty overload with motor rated current = drive rated current
Heavy Duty overload with motor rated current = drive rated current
Open loop

175 % for 42 s 175 % for 5 s 150 % for 60 s 150 % 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 2 kHz switching frequency. Derating is required for higher switching frequencies, ambient temperatures >40 °C (104 °F) and higher altitude. For further information, refer to Chapter
5.1 Drive technical data on page 73.
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.

3.1 Safety information

Follow the instructions
The mechanical and electrical installation instructions must be adhered to. Any questions or doubt should be referred to the supplier of the equipment. It is the responsibility of the owner or user to ensure that the installation of the drive and any external option unit, and the way in which they are operated and maintained, comply with the requirements of the Health and Safety at Work Act in the United Kingdom or applicable legislation and regulations and codes of practice in the country in which the equipment is used.
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

NOTE
The following considerations must be made when planning the installation:
3.2.1 Access
Access must be restricted to authorized personnel only. Safety regulations which apply at the place of use must be complied with.
The IP (Ingress Protection) rating of the drive is installation dependent. For further information, refer to section 3.9 Enclosing standard drive for high environmental protection on page 31.
3.2.2 Environmental protection
The drive must be protected from:
Moisture, including dripping water or spraying water and condensation. An anti-condensation heater may be required, which must be switched off when the drive is running.
Contamination with electrically conductive material
Contamination with any form of dust which may restrict the fan, or impair airflow over various components
Temperature beyond the specified operating and storage ranges
Corrosive gasses
During installation it is recommended that the vents on the drive are covered to prevent debris (e.g. wire off-cuts) from entering the drive.
3.2.3 Cooling
The heat produced by the drive must be removed without its specified operating temperature being exceeded. Note that a sealed enclosure gives much reduced cooling compared with a ventilated one, and may need to be larger and/or use internal air circulating fans.
For further information, refer to section 3.6 Enclosure for standard drives on page 26.
3.2.4 Electrical safety
The installation must be safe under normal and fault conditions. Electrical installation instructions are given in Chapter 4 Electrical installation on page 41.
3.2.5 Fire 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.

3.2.6 Electromagnetic compatibility
Variable speed drives are powerful electronic circuits which can cause electromagnetic interference if not installed correctly with careful attention to the layout of the wiring.
Some simple routine precautions can prevent disturbance to typical industrial control equipment.
If it is necessary to meet strict emission limits, or if it is known that electromagnetically sensitive equipment is located nearby, then full precautions must be observed. In-built into the drive, is an internal EMC filter, which reduces emissions under certain conditions. If these conditions are exceeded, then the use of an external EMC filter may be required at the drive inputs, which must be located very close to the drives. Space must be made available for the filters and allowance made for carefully segregated wiring. Both levels of precautions are covered in section 4.13 EMC (Electromagnetic compatibility) on page 58.
3.2.7 Hazardous areas
The drive must not be located in a classified hazardous area unless it is installed in an approved enclosure and the installation is certified.

3.4 Dimensions and mounting methods

The Unidrive M/HS Frame 11E can be either surface or through-panel mounted using the appropriate brackets. Surface mounting is where the drive is simply secured to the enclosure wall/backplate.
Through-panel mounting is where the drive is secured with the heatsink protruding through the enclosure panel to the external environment. This has the effect of reducing the temperature within the enclosure.
The following drawings show the dimensions of the drive and mounting holes for each method to
allow a back plate to be prepared.
If the drive has been used at high load levels for a period of time, the heatsink can reach temperatures in excess of 70 °C (158 °F). Human contact with the heatsink should be prevented.

NOTE
1. Add the dissipation figures from section 5.1.3 Power dissipation on page 76 for each drive that is 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
5.2.2 EMC filter ratings on page 89 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.

3.7 Enclosure 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.

3.8 Heatsink fan operation

The Unidrive M / Unidrive HS size 11E are ventilated by a heatsink mounted fan and an auxiliary fan to ventilate the drive box. 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 installation 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 Unidrive M / Unidrive HS size 11E is a variable speed device. 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 drive is also installed with a variable speed fan to ventilate the capacitor bank.

NOTE
protection
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 a higher IP rating at the rear of the heatsink when through-panel mounted.
This allows the front of the drive, along with various switchgear, to be housed in an IP55 (NEMA 12) 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 gasket provided in the through panel mounting kit.
Figure 3-11 Example of high IP through-panel layout
Safety information Product information
Mechanical installation
Electrical installation Technical data UL listing information
The main gasket should be installed as shown in Figure 3-11. Any screws / bolts that are used for mounting should be installed with M8 flat nylon washers to maintain a seal around the screw hole.
See Figure 3-12 on page 32, sealing clamps are supplied in the through panel mounting kit to aid compression of the gasket.
The heatsink fans have conformal coated PCBs and have sealant at cable entry points. 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.

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.
Safety information Product information Mechanical installation

Technical data UL listing information
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).
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.

Number of phases: 3
Maximum supply imbalance: 2 % negative phase sequence (equivalent to 3 % voltage imbalance between phases).

Model Symmetrical fault level (kA)
All 100
4.3.1 Supply types
All drives are suitable for use on any supply type i.e TN-S, TN-C-S, TT and IT.
Supplies with voltage up to 600 V may have grounding at any potential, i.e. neutral, centre or corner (“grounded delta”)
Supplies with voltage above 600 V may not have corner grounding
Drives are suitable for use on supplies of installation category III and lower, according to IEC 60664-1. 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, additional independent motor ground fault protection must be provided, refer to Table 4-2. For 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.

4.4 Line reactors

H
W
D
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.
Drive size 11E does not have internal input line reactor hence an external input line reactor must be used.
Each drive must have its own reactor(s). Three individual reactors or a single three-phase 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

4.5 24 Vdc supply

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. Low Under Voltage Threshold Select (06.067) must also be enabled for this to happen.
On size 11, the power 24 Vdc supply (terminals 51, 52) must be connected to enable the 24 V dc supply to be used as a backup supply, when the line power supply is removed. If the power 24 Vdc supply is not connected none of the above mentioned functions can be used, "Waiting For Power System" will be displayed on the keypad and no drive operations are possible.

4.6 Low voltage operation

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:
Size 11
Minimum continuous operating voltage: 26 V
Minimum start up voltage: 32 V
Maximum over voltage trip threshold: 230 V drives: 415 V

NOTE
WARNING
WARNING
See section 2.4 Ratings on page 13.
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 high imbalance. 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 4-5.
Table 4-5 Supply fault current used to calculate maximum input currents
Model Symmetrical fault level (kA)
All sizes 100
The nominal cable sizes given in section 2.4 Ratings are only a guide. Refer to local wiring regulations for the correct size of cables. In some cases a larger cable is required to avoid excessive voltage drop.
The nominal output cable sizes in section 2.4 Ratings on page 13 assume that the motor maximum current matches that of the drive. Where a motor of reduced rating is used the cable rating may be chosen to match that of the motor. To ensure that the motor and cable are protected against over-load, the drive must be programmed with the correct motor rated current.
Fuses
The AC supply to the drive must be installed with suitable protection against overload and short-circuits. Nominal fuse ratings are shown in section 2.4 Ratings on page 13. Failure to observe this requirement will cause risk of fire.
A fuse or other protection must be included in all live connections to the AC supply.
Fuse types
The fuse voltage rating must be suitable for the drive supply voltage.

4.10 Output circuit and motor protection

The output circuit has fast-acting electronic short-circuit protection which limits the fault current to typically no more than five times the rated output current, and interrupts the current in approximately 20 µs. No additional short-circuit protection devices are required.
The drive provides overload protection for the motor and its cable. For this to be effective, Rated
Current (00.046) must be set to suit the motor.
Rated Current (00.046) must be set correctly to avoid a risk of fire in the event of motor
overload.
There is also provision for the use of a motor thermistor to prevent over-heating of the motor, e.g. due to loss of cooling.

4.10.1 Motor cable types
Normal capacitance
Shield or armour separated from the cores
High capacitance
Shield or armour close to the cores
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 5-22 Maximum motor cable lengths on page 85
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
4.10.2 High-capacitance / reduced diameter cables
The maximum cable length is reduced from that shown in Table 5-22 Maximum motor cable lengths on page 85 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 4-6 shows how to identify the two types).
Figure 4-6 Cable construction influencing the capacitance
Safety information Product information Mechanical installation
Electrical installation
The maximum motor cable lengths specified in section 5.1.22 Maximum motor cable lengths on page 85 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).
4.10.3 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:

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.

4.11 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 4-6 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 Braking IGBT Lower Threshold (06.073) and Braking IGBT Upper Threshold (06.074).

When a braking resistor is used, Pr 00.015 should be set to Fast Ramp Mode.
High temperatures Braking resistors can reach high temperatures. Locate braking resistors so that damage cannot result. Use cable having insulation capable of withstanding high temperatures.
4.11.1 Braking resistor
Overload protection
When a braking resistor is used, it is essential that an overload protection device is incorporated in the braking resistor circuit; this is described in Figure 4-9 on page 56.
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 4­10 General EMC enclosure layout showing ground connections on page 59 for further details.
Internal connection does not require the cable to be armored or shielded.

* Resistor tolerance: ±10 %.
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.
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 4-9 shows a typical circuit arrangement.

4.11.2 Braking resistor software overload protection
The drive software contains an overload protection function for a braking resistor. In order to enable and set-up this function, it is necessary to enter three values into the drive:
Braking Resistor Rated Power (10.030)
Braking Resistor Thermal Time Constant (10.031)
Braking Resistor Resistance (10.061)
This data should be obtained from the manufacturer of the braking resistors.
Pr 10.039 gives an indication of braking resistor temperature based on a simple thermal model. Zero indicates the resistor is close to ambient and 100 % is the maximum temperature the resistor can withstand. A ‘Brake Resistor’ alarm is given if this parameter is above 75 % and the braking IGBT is active. A Brake R Too Hot trip will occur if Pr 10.039 reaches 100 %, when Pr 10.037 is set to 0 (default value) or 1.
If Pr 10.037 is equal to 2 or 3, a Brake R Too Hot trip will not occur when Pr 10.039 reaches 100 %, but instead the braking IGBT will be disabled until Pr 10.039 falls below 95 %. This option is intended for applications with parallel connected DC buses where there are several braking resistors, each of which cannot withstand full DC bus voltage continuously. With this type of application it is unlikely the braking energy will be shared equally between the resistors because of voltage measurement tolerances within the individual drives. Therefore with Pr 10.037 set to 2 or 3, then as soon as a resistor has reached its maximum temperature the drive will disable the braking IGBT, and another resistor on another drive will take up the braking energy. Once Pr 10.039 has fallen below 95 % the drive will allow the braking IGBT to operate again.
See the Parameter Reference Guide for more information on Pr 10.030, Pr 10.031, Pr 10.037 and Pr 10.039.
This software overload protection should be used in addition to an external overload protection device.

4.12 Ground leakage

WARNING
WARNING
The size 11E drive has an internal EMC capacitor installed, this capacitor is not removable. The ground leakage current is as follows:
56 mA AC at 400 V 50 Hz (proportional to supply voltage and frequency) 18 µA DC with a 600 V DC bus (33 MΩ)
Note there is an internal voltage surge protection device connected to ground. Under normal
circumstances this carries negligible current.
The ground leakage current is high. A permanent fixed ground connection must be provided, or other suitable measures taken to prevent a safety hazard occurring if the connection is lost.
4.12.1 Use 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
Safety information Product information Mechanical installation
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.

4.13 EMC (Electromagnetic compatibility)

WARNING
NOTE
WARNING
The requirements for EMC are divided into three levels in the following three sections:
Section 4.13.2, General requirements for all applications, to ensure reliable operation of the drive and minimise the risk of disturbing nearby equipment. The immunity standards specified in section 11 will be met, but no specific emission standards. Note also the special requirements given in Surge immunity of control circuits - long cables and connections outside a building on page 71 for increased surge immunity of control circuits where control wiring is extended.
Section 4.13.3, Requirements for meeting the EMC standard for power drive systems, IEC61800-3 (EN 61800-3:2004+A1:2012).
Section 4.13.4, Requirements for meeting the generic emission standards for the industrial environment, IEC61000-6-4, EN 61000-6-4:2007+A1:2011.
The recommendations of section 4.13.2 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 4.13.3 or section 4.13.4 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
The correct external EMC filter must be used, and all of the guidelines in section 4.13.2 and section
4.13.4 must be followed.
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 where the drive is to be used.
4.13.1 Internal EMC filter
The size 11E drive has an internal EMC capacitor installed, this capacitor is not removable. This (and the lack of a negative DC terminal) mean that the size 11E drive is not suitable for use as part of a
regen system.
The non removable internal EMC filter means the drive is not suitable for use with ungrounded (IT) supplies unless additional motor ground fault protection is installed. For details of ground fault protection contact the supplier of the drive.
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 4.13.3. For longer motor cables the filter continues to provide a useful reduction in emission level, 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.

Feedback device cable shielding
NOTE
NOTE
Shielding considerations are important for PWM drive installations due to the high voltages and currents present in the output (motor) circuit with a very wide frequency spectrum, typically from 0 to 20 MHz.
The following guidance is divided into two parts:
1. Ensuring correct transfer of data without disturbance from electrical noise originating either within the drive or from outside.
2. Additional measures to prevent unwanted emission of radio frequency noise. These are optional and only required where the installation is subject to specific requirements for radio frequency emission control.
To ensure correct transfer of data, observe the following:
Resolver connections:
Use a cable with an overall shield and twisted pairs for the resolver signals
Connect the cable shield to the drive 0V connection by the shortest possible link ("pigtail")
It is generally preferable not to connect the cable shield to the resolver. However in cases where there is an exceptional level of common-mode noise voltage present on the resolver body, it may be helpful to connect the shield there. If this is done then it becomes essential to ensure the absolute minimum length of "pigtails" at both shield connections, and possibly to clamp the cable shield directly to the resolver body and to the drive grounding bracket.
The cable should preferably not be interrupted. If interruptions are unavoidable, ensure the absolute minimum length of "pigtail" in the shield connections at each interruption.
Encoder connections:
Use a cable with the correct impedance
Use a cable with individually shielded twisted pairs
Connect the cable shields to 0V at both the drive and the encoder, using the shortest possible links ("pigtails")
The cable should preferably not be interrupted. If interruptions are unavoidable, ensure the absolute minimum length of "pigtail" in the shield connections at each interruption. Preferably, use a connection method which provides substantial metallic clamps for the cable shield terminations.
The above applies where the encoder body is isolated from the motor and where the encoder circuit is isolated from the encoder body. Where there is no isolation between the encoder circuits and the motor body, and in case of doubt, the following additional requirement must be observed. This gives the best possible noise immunity.
The shields must be directly clamped to the encoder body (no pigtail) and to the drive grounding bracket. This may be achieved by clamping of the individual shields or by providing an additional overall shield which is clamped.
The recommendations of the encoder manufacturer must also be adhered to for the encoder connections.
Safety information Product information Mechanical installation
Electrical installation
Technical data UL listing information
In order to guarantee maximum noise immunity for any application double shielded cable as shown should be used.
In some cases single shielding of each pair of differential signals cables, or a single overall shield with individual shield on the thermistor connections is sufficient. In these cases all the shields should be connected to ground and 0V at both ends.
If the 0V is required to be left floating, a cable with individual shields and an overall shield must be used.

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 4.13.4 Compliance with generic emission standards on
page 64. 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 Unidrive M / Unidrive HS 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. The requirements of operating in the second environment are met, depending on the motor cable length for 3 kHz switching frequency as stated in Table 4-8.
The table summarizes the performance of in-built filters when used with Unidrive M / Unidrive HS size 11 drives and single pairs of Unidrive M / Unidrive HS size 11 drives and Unidrive M / Unidrive HS rectifiers, assembled in the standard recommended configuration.

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 0.3m (12 in) away from the terminal block.
Figure 4-20 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.
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.

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 0V 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 0V terminal to ground. Avoid loops in the control wiring, i.e. ensure every control wire is accompanied by its return (0V) 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 mm 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 4-22 and Figure 4-23.
If a digital port experiences a severe surge its protective trip may operate (O.Ld1 trip code 26). 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 Bipolar TT-UKK5-D/24 AC
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.

5.1.8 Storage
-40 °C (-40 °F) to +55 °C (122 °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.

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 %.
5.1.10 IP / UL Rating
The 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 IP55 rating (NEMA 12) at the rear of the heatsink for through-panel mounting (some current derating is required).
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 5-10.

5.1.16 Output frequency / speed range
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 Accuracy and resolution
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.
Open loop resolution:
Preset frequency reference: 0.1 Hz Precision frequency reference: 0.001 Hz
Closed loop resolution
Preset speed reference: 0.1 rpm Precision speed reference: 0.001 rpm Analog input 1: 11 bit plus sign Analog input 2: 11 bit plus sign
Current:
The resolution of the current feedback is 10 bit plus sign.
Accuracy: typical 2 %

5.1.21 Input current, fuse and cable size ratings
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 5-15.

IEC 61800-3 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.
Power drive systems are categorized C1 to C4:
Category Definition
C1 Intended for use in the first or second environments
C2
Not a plug-in or movable device, and intended for use in the first environment only when installed by a professional, or in the second environment
C3 Intended for use in the second environment, not the first environment
C4
Intended for use in the second environment in a system rated at over 400 A, or in a complex system
Note that category 4 is more restrictive than E2R, since the rated current of the PDS must exceed 400 A or the supply voltage exceed 1000 V, for the complete PDS.
