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.

Drive firmware version

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

1.1 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 Installation Guide.

1.3 System design and safety of

The drive is intended as a component for professional incorporation into complete equipment or a system. If installed incorrectly, the drive may present a safety hazard.

The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used to control equipment which can cause injury.

Close attention is required to the electrical installation and the system design to avoid hazards either in normal operation or in the event of equipment malfunction. System design, installation, commissioning/ start-up and maintenance must be carried out by personnel who have the necessary training and experience. They must read this safety information and this 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 should 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.

1.5 Access

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

1.6 Fire protection

The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided. For further information, refer to section

5.2.5 Fire protection on page 39.

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 Installation Guide contains instruction for achieving compliance with specific EMC standards.

Within the European Union, all machinery in which this product is used must comply with the following directives:

Safety of Machinery 2006/42/EC Electromagnetic Compatibility (EMC) Directive 2014/30/EU

1.8 Motor

Ensure the motor is installed in accordance with the manufacturer’s recommendations. Ensure the motor shaft is not exposed.

Standard squirrel cage induction motors are designed for single speed operation. If it is intended to use the capability of the drive to run a motor at speeds above its designed maximum, it is strongly recommended that the manufacturer is consulted first.

Low speeds may cause the motor to overheat because the cooling fan becomes less effective. The motor should be installed with a protection thermistor. If necessary, an electric forced vent fan should be used.

The values of the motor parameters set in the drive affect the protection of the motor. The default values in the drive should not be relied upon.

It is essential that the correct value is entered in Pr 00.046 motor rated current. This affects the thermal protection of the motor.

1.9 Mechanical brake control

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

1.10 Adjusting parameters

Some parameters have a profound effect on the operation of the drive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering.

1.4 Environmental limits

Instructions in this Installation Guide regarding transport, storage, installation and use of the drive must be complied with, including the specified environmental limits. Drives must not be subjected to excessive physical force.

2 Introduction

The Unidrive M / Unidrive HS modular drive offers the possibility of implementing many custom power systems with a wide range of power modules. The power range is 110 kW to 2.8 MW and the modular design of input and output stages enables a wide range of very compact and efficient systems to be realized. These include:

• Parallel output stages for higher power motors:

Size 9 and 10:

Up to a maximum of 20 modules (1 master module with up to 19 follower modules, OR 1 remote mounted control master pod controlling up to 20 followers. This allows the user to place all control circuitry in one low voltage cabinet)

Size 11:

Up to a maximum of 10 modules (1 master module with up to 9 follower modules OR 1 remote mounted control master pod controlling up to 10 followers).

• Common DC bus multi-drive systems for: Connection to larger existing power supplies Energy sharing between motoring and regenerating drives

• Active front end drive systems for: Minimizing supply current harmonics Four quadrant motor control

• Multiple controlled rectifier bridges for: Minimizing supply current harmonics by drawing 6, 12 or 18 pulse supply load currents.

2.1 Rectifier

A separate input line reactor (INLXXX) of at least the value shown in Table 6-2 Model and line reactor part numbers on page 93 must be used with the rectifiers. Failure to provide sufficient reactance could damage or reduce the service life of the rectifier or inverter.

The Unidrive M / Unidrive HS rectifier is a half controlled SCR/thyristor bridge and is used as a front end to the size 9, size 10 or size 11 inverter module. The rectifier cannot be used as a stand alone rectifier for several smaller drives.

3.1 Ratings

The drive is dual rated. The setting of the motor rated current determines which rating applies Heavy Duty or Normal Duty. The two ratings are compatible with motors designed to IEC60034. The graph aside illustrates the difference between Normal Duty and Heavy Duty with respect to continuous current rating and short term overload limits.

Technical data UL Information

Normal Duty Heavy Duty (default)

For applications which use Self ventilated (TENV/TEFC) induction motors and require a low overload capability, and full torque at low speeds is not required (e.g. fans, pumps). Self ventilated (TENV/TEFC) induction motors require increased protection against overload due to the reduced cooling effect of the fan

at low speed. To provide the correct level of protection the I operates at a level which is speed dependent. This is illustrated in the graph below.

The speed at which the low speed protection takes effect can be changed by the setting of Low Speed Thermal Protection Mode (04.025). The protection starts when the motor speed is below 15 % of base speed when Pr 04.025 = 0 (default) and below 50 % when Pr 04.025 = 1.

Operation of motor I2t protection

Motor I2t protection is fixed as shown below and is compatible with:

• Self ventilated (TENV/TEFC) induction motors

t software

For constant torque applications or applications which require a high overload capability, or full torque is required at low speeds (e.g. winders, hoists). The thermal protection is set to protect force ventilated induction motors and permanent magnet servo motors by default.

If the application uses a self ventilated (TENV/TEFC) induction motor and increased thermal protection is required for speeds below 50 % base speed, then this can be enabled by setting Low Speed Thermal Protection Mode (04.025) = 1.

Motor I2t protection defaults to be compatible with:

• Forced ventilation induction motors

• Permanent magnet servo motors

3.1.1 Typical short term overload limits

The maximum percentage overload limit changes depending on the selected motor. Variations in motor rated current, motor power factor and motor leakage inductance all result in changes in the maximum possible overload. The exact value for a specific motor can be calculated using the equations detailed in Menu 4 in the Parameter Reference Guide.

Typical values are shown in the table below for RFC (RFC-A or RFC-S) and open loop (OL) modes:

Table 3-6 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 (size 9, 10 and 11)

Open loop from

110 % for 165 s 110 % for 9 s 110 % for 165 s 110 % for 9 s

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.

3.2 Operating modes

The drive is designed to operate in any of the following modes:

1. Open loop mode Open loop vector mode Fixed V/F mode (V/Hz) Quadratic V/F mode (V/Hz)

2. RFC - A mode

With position feedback sensor Without position feedback sensor (Sensorless)

3. RFC - S mode

With position feedback sensor Without position feedback sensor (Sensorless)

4. Regen mode

3.2.1 Open loop mode

The drive applies power to the motor at frequencies varied by the user. The motor speed is a result of the output frequency of the drive and slip due to the mechanical load. The drive can improve the speed control of the motor by applying slip compensation. The performance at low speed depends on whether V/F mode or open loop vector mode is selected.

Open loop vector mode

The voltage applied to the motor is directly proportional to the frequency except at low speed where the drive uses motor parameters to apply the correct voltage to keep the flux constant under varying load conditions.

Typically 100 % torque is available down to 1 Hz for a 50 Hz motor.

Fixed V/F mode

The voltage applied to the motor is directly proportional to the frequency except at low speed where a voltage boost is provided which is set by the user. This mode can be used for multi-motor applications.

Typically 100 % torque is available down to 4 Hz for a 50 Hz motor.

Quadratic V/F mode

The voltage applied to the motor is directly proportional to the square of the frequency except at low speed where a voltage boost is provided which is set by the user. This mode can be used for running fan or pump applications with quadratic load characteristics or for multi-motor applications. This mode is not suitable for applications requiring a high starting torque.

3.2.2 RFC-A mode

Rotor Flux Control for Asynchronous (induction) motors (RFC-A) encompasses closed loop vector control with a position feedback device

With position feedback

For use with induction motors with a feedback device installed. The drive directly controls the speed of the motor using the feedback device to ensure the rotor speed exactly as demanded. Motor flux is accurately controlled at all times to provide full torque all the way down to zero speed.

Without position feedback (Sensorless)

Sensorless mode provides closed loop control without the need for position feedback by using current, voltages and key motor parameters to estimate the motor speed. It can eliminate instability traditionally associated with open loop control such as operating large motors with light loads at low frequencies.

3.2.3 RFC-S mode

Rotor Flux Control for Synchronous (permanent magnet brushless) motors (RFC-S) provides closed loop control with position feedback device.

With position feedback

For use with permanent magnet brushless motors with a feedback device installed.

The drive directly controls the speed of the motor using the feedback device to ensure the rotor speed is exactly as demanded. Flux control is not required because the motor is self excited by the permanent magnets which form part of the rotor.

Absolute position information is required from the feedback device to ensure the output voltage is accurately matched to the back EMF of the motor. Full torque is available all the way down to zero speed.

3.2.4 Regen mode

For use as a regenerative front end for four quadrant operation.

Regen operation allows bi-directional power flow to and from the AC supply. This provides far greater efficiency levels in applications which would otherwise dissipate large amounts of energy in the form of heat in a braking resistor.

The harmonic content of the input current is negligible due to the sinusoidal nature of the waveform when compared to a conventional bridge rectifier or SCR/thyristor front end.

4.1.1 DC fusing

The Unidrive M/HS modular system has undergone safety testing and proving when using the specified AC input fuses, including the case where the size 11 twin rectifier is used to supply two D type modules. A fault in any module is cleared by the AC input fuses.

If more rectifiers or inverters are connected to the DC bus then the prospective fault current and the energy delivered before a fault is cleared are increased because of the multiple sources and the increased stored energy in the inverter capacitors. It then becomes necessary to provide fuses in the DC bus. This is illustrated in Figure 4-13.

Figure 4-13 Fault current contributions

As shown in Figure 4-14 when DC fuses are required they must be placed in the rectifier output circuits as well as the inverter inputs, since they are also exposed to the total fault-current infeed. For the size 11 twin rectifier, only one fuse pair is needed for the complete module.

The only exception to this rule is where the rectifier input fuses are reduced in rating so that the total i2t let-through for all of the phases is no greater than that for the standard recommended fuses for the 6-pulse arrangement. This will be the case for some of the lower-power multi-pulse arrangements. This needs to be verified on a case-by-case basis.

All DC fuses are in pairs, i.e. one in each pole, to provide protection against earth faults.

Figure 4-14 12-pulse system using twin rectifiers and 6-phase AC distribution with odd number of inverter modules

Please see Table 6-15 DC fuse and cable ratings for Unidrive M / HS size 9, 10 and 11 inverters on page 102 for DC fuse ratings.

5 Mechanical Installation

This chapter describes all the mechanical details required to install the drive. The drive is intended to be installed in an enclosure. Key features of this chapter include:

• Surface and through-panel mounting

• Remote mounting of control master pod

• Enclosure sizing and layout

• Terminal location and torque settings

5.1 Safety information

Follow the instructions

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

Competence of the installer

The drive must be installed by professional assemblers who are familiar with the requirements for safety and EMC. The assembler is responsible for ensuring that the end product or system complies with all the relevant laws in the country where it is to be used.

Many of the drives in this product range weigh in excess of 15 kg (33 lb). Use appropriate safeguards when lifting these models.

Installation

Technical data UL Information

5.2.3 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, please refer to section 5.6.4 Enclosure sizing on page 64.

5.2.4 Electrical safety

The installation must be safe under normal and fault conditions. Electrical installation instructions are given in Chapter 6 Electrical Installation on page 85.

5.2.5 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 5-1. 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.

Figure 5-1 Fire enclosure bottom layout

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.

5.2 Planning the installation

The following considerations must be made when planning the installation:

5.2.1 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.

5.2.2 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.

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 5-2 for acceptable baffle construction. This does not apply for mounting in an enclosed electrical operating area (restricted access) with concrete floor.

5.2.6 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 6.13 EMC (Electromagnetic compatibility) on page 108.

5.2.7 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.

5.3 Terminal cover removal

Isolation device

The AC supply must be disconnected from the drive using an approved isolation device before any cover is removed from the drive or before any servicing work is performed.

Mechanical Installation

Electrical

Installation

Technical data UL Information

Stored charge

Normally, the capacitors are discharged by an internal resistor. Under certain, unusual fault conditions, it is possible that the capacitors may fail to discharge, or be prevented from being discharged by a voltage applied to the output terminals. If the drive has failed in a manner that causes the display to go blank immediately, it is possible the capacitors will not be discharged. In this case, consult Control Techniques or their authorized distributor.

5.3.1 Removing the terminal covers

Unidrive M / Unidrive HS size 9/10/11 D and E are installed with three terminal covers: Control, input and output terminal covers.

Unidrive M / Unidrive HS rectifiers are installed with two terminal covers: Input and output terminal covers. The terminal covers must be removed to gain access to all the terminals.

5.5 Dimensions and mounting methods

Unidrive M / Unidrive HS size 9, 10, 11 and rectifier 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.

Many of the drives in this product range weigh in excess of 15 kg (33 lb). Use appropriate safeguards when lifting these models. Use the appropriate lifting bracket as shown in Figure 3-7 Options available for Unidrive M/HS modular drives on page 24.

5.6.2 Enclosure 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

rate

) which

should be used for any 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

= T

rate

+ 5° C

2. Totally enclosed with air flow (>2 m/s) over the drive T

Where:

rate

5.6.3 Altitude derating

Multiply the maximum rated output current by the derate factor (Df) in Figure 5-31 and the ambient correction factor (Cf) in Figure 5-32.

Rated output current = Df x Cf x Oc

Figure 5-31 Altitude derate factor

Mechanical Installation

Electrical

Installation

Technical data UL Information

Figure 5-32 Ambient temperature correction factor

• The ambient temperature correction factor used is for altitude calculation only. If the ambient is less than 40°C the drive cannot be over rated. The maximum permissible output currents should remain the same as those given at 40 °C.

• If the drive is required to operate above 40 °C the derates at 50 °C should be applied.

• The same applies for altitude below 1000 m. There should be no over rating at lower altitude

For applications over 3000 m, contact the supplier of the drive.

5.6.4 Enclosure sizing

This section looks at a method for cooling a medium power density enclosure. By running through a worked example it brings out the issues associated with cooling the drives when they are completely mounted inside an enclosure.

This example only considers one possible method of enclosing the drives and tries to highlight and solve thermal issues created by hot air recirculating inside an enclosure. Other methods of enclosure design are also possible, such as through panel mounting, which removes many of the issues discussed in this chapter. Refer to section 5.5.2 Through- panel mounting on page 54.

The enclosure design example will use the following conditions:

• Enclosure placed in a room with a 30°C ambient and an altitude <1000 m

• Continuous output current requirement from the system = 650 A

Parts used in system model:

• 1800 mm (70.87 in) x 800 mm (31.5 in) x 500 mm (19.69 in) enclosure with input and output ventilation

• 2 x 10402700

• 2 x input line reactors (L1)

• 2 x output sharing chokes (L2)

Calculate temperature rise

Table 5-6 Air flow rates

Modules Flow rate (m3/hr)

Calculating temperature rise in enclosure

dT = 3kPr/V

Where:

V = Airflow in m

/hr (Unidrive flow rate = 305)

dT = Temperature rise Pr = Loss affecting drive temp k = 1 / Altitude de-rate

Therefore ambient temperature rise (dT):

= (3 x 1 x 3510.4) / 305

= 34.5 °C

So,

Ambient temperature inside enclosure = External ambient + temperature rise = 64.5 ° C

This shows that with the maximum allowable ambient drive temperature of 40 °C, the enclosure will overheat.

Processing results

Option 1: If the absolute temperature inside the enclosure is still less

than 50 °C, select a drive with the correct rating at 50 ° C.

Option 2: Add more venting, if possible, to reduce the recirculation and recalculate.

Option 3: Add an enclosure fan.

Option 4: Redesign the enclosure so that the drives can be through

panel mounted. This means that most of the heat can escape outside the main enclosure, and the input air into the heat sinks will remain at the external ambient and not be affected by recirculation. Refer to section

5.5.2 Through-panel mounting on page 54.

This is an approximation of the amount of air that is re-circulated within the enclosure due to inlet and outlet venting restrictions. The factor has a safety factor built in to it to ensure a safe result. The factor has been calculated using CFD software, testing the amount of heat flow back into the drive when different vent restrictions are given. The factor can also be applied to an Unidrive M / Unidrive HS size 9/10 E and separated Unidrive M / Unidrive HS size 9/10 D.

Calculate loss which affects the drive inlet air temperature

Loss affecting drive temperature (Pr) = Lower choke Loss (Pc) + (Total loss of single drive (Dp) x Recirculation factor (Rf))

= 250 + (4290 x 0.76)

= 3510 W

This is the loss from 1 drive unit only as simulations have shown that with drives mounted inline and in a symmetric system the losses are shared equally.

Heat loss through the front of the drive still needs to be considered.

Adding enclosure fan

Calculate required flow rate

• Fan needs to remove the effect of re-circulation and the added choke loss.

• Loss affecting drive temp (Pr) = 3510.4 W

• The above Loss of 3510.4 W is for one drive only, so with an enclosure of 2 units the total loss to remove = 7020.8 W

Calculate the temperature rise allowed in the enclosure:

Temperature rise (dT) = (Allowable drive ambient - 5 {safety

factor}) - External ambient

= (40 - 5) - 30

= 5 °C

Then using:

V = 3kPr/ (dT)

Flow rate required to remove loss = (3x1x7020.8) / 5

= 4212.5 m

Calculate back pressure on fan

Best practice: Size the enclosure air inlet and exit vents at least as

large as the venturi opening of the fan used. This will ensure a negligible back pressure.

With 52.5 % open area: Pressure drop = 34

Selecting fan

Considerations when selecting fan:

• Dimensions and space limitation

• Required flow rate

• Static pressure

•Noise level

• Power supply

Backward curved Blower (Centrifugal)

• Outward flow perpendicular to inward flow

• Good at high + low back pressures

• Good resistance to dust and dirt due to impeller design

• Do not need cowling

• Relatively small diameters required for high airflow

Forward curved blower (Centrifugal)

• Requires cowling

• Good at directing flow

Axial Fan

• Not good at high pressure but good for low pressure applications such as room venting and ducting

• Inward flow and outward flow is in same direction

• Good in straight line duct applications.

• Large diameters required for high air flows

Once the type of fan has been selected the next step is to match the system characteristics of your enclosure to the fan performance curve.

Final summary

1. Enclosure fans can be placed on inlet and outlet depending on

system limitations.

2. Considerations with fan on outlet:

• Higher Ambient temperature surrounding fan, can affect fan life.

• Depressurisation of enclosure which may draw in dust through any apertures.

3. Considerations with fan on inlet:

• Proximity of dust filter to fan, can create excess back pressure on fan

• Non-uniform flow across internal components

4. Dust filters: Use the largest filter possible, in order to:

a. Increase dust capacity b. Reduce pressure drop

5. Make sure Drive inlets are as close to the enclosure air inlet as possible

6. Do not block the inlet and outlets of the drive airflow. Keep to best practice spacing between drives and other parts in enclosure.

7. Beware of blocking air inlets or outlets with cable routing.

5.7 Heatsink fan operation

The Unidrive M / Unidrive HS size 9, 10, 11 and the rectifier 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 9, 10, 11 and the rectifier 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 Unidrive M / Unidrive HS size 9, 10 and 11 are also installed with variable speed fans to ventilate the capacitor bank.

5.8 Enclosing drive for high environmental 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 gaskets provided.

Figure 5-38 Example of high IP through-panel layout

The main gasket should be installed as shown in Figure 5-38. 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 5-39 on page 69, 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.

6 Electrical Installation

Many cable management features have been incorporated into the product and accessories, this chapter shows how to optimize them. Key features include:

• Safe Torque Off function

• 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 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.

Use of rectifiers other than Unidrive M / Unidrive HS rectifier

If a rectifier other than Unidrive M / Unidrive HS Rectifier is used with Unidrive M / Unidrive HS size 9D/10D/11D, then it must be installed with line to ground varistors which are capable of reducing overvoltage transients from category III to values of category II. (ref. EN61800-5-1). This is to ensure L-E transients do not exceed 4 kV because there are no varistors installed in a D module, and the insulation system from power to ground is designed to category II. Any non Control Techniques rectifier must be installed with AC line fuses that correspond to those specified for the Unidrive M / Unidrive HS rectifier. If this is not possible then DC fuses should be specified for the Unidrive M / Unidrive HS size 9D/10D/11D. This is to ensure validity of the safety testing carried out to complete the safety file and for UL certification, especially in the event of a short circuit bus cap in the DC bus.

0V control connections on both Unidrive M / Unidrive HS sizes 9, 10 and 11 drives are internally earthed and cannot be disconnected. Ensure that there is adequate equipotential bonding between parts of a system with interconnected control wiring.

The power supply to all modules in a multi-module system should be applied at the same time, to ensure the drive powers-up correctly. Otherwise the drive may power-up with a hardware fault (HF) trip code.

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

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.

6.1.3 Ground connections

The drive must be connected to the system ground of the AC supply. The ground wiring must conform to local regulations and codes of

practice.

The ground loop impedance must conform to the requirements of local safety regulations.

The drive must be grounded by a connection capable of carrying the prospective fault current until the protective device (fuse, etc.) disconnects the AC supply.

The ground connections must be inspected and tested at appropriate intervals.

Electrochemical corrosion of earthing terminals

Ensure that grounding terminals are protected against corrosion i.e. as could be caused by condensation.

On a Unidrive M/Unidrive HS size 9, 10, 11 and rectifiers, the supply and motor ground connections are made using an M10 bolt at the top (supply) and bottom (motor) of the drive. See Figure 6-9 to Figure 6-14.

Number of phases: 3

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

Frequency range: 45 to 66 Hz

The maximum supply symmetrical fault current must be limited to 100 kA (also required for UL compliance).

6.2.1 Supply types

Drives rated for supply voltage up to 575 V are suitable for use with any supply type, i.e. TN-S, TN-C-S, TT, IT, with grounding at any potential, i.e. neutral, centre or corner ("grounded-delta").

Grounded delta supplies >575 V are not permitted.

Drives are suitable for use on supplies of installation category III and lower, according to IEC60664-1. This means they may be connected permanently to the supply at its origin in a building, but for outdoor installation additional over-voltage suppression (transient voltage surge suppression) must be provided to reduce category IV to category III.

Operation with IT (ungrounded) supplies: Special attention is required when using internal or external EMC filters with ungrounded supplies, because in the event of a ground (earth) fault in the motor circuit the drive may not trip and the filter could be over-stressed. In this case, either the filter must not be used (removed) or additional independent motor ground fault protection must be provided, refer to Table 6-1. 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.

6.2.3 Supplies requiring additional line reactance

Additional line reactance reduces the risk of damage to the drive resulting from poor phase balance or severe disturbances on the supply network. It also reduces harmonic current emission.

Where additional line reactance is to be used, added reactance of approximately 2 % is 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 % additional reactance permits 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.

• Direct-on-line 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.

When required, 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

6.2.4 Additional input inductance calculation

To calculate the additional inductance required (at Y%), use the following equation:

Where:

I = drive rated input current (A)

L = inductance (H) f = supply frequency (Hz) V = voltage between lines

6.3.2 Cooling requirements for higher output frequencies

Single OTL output sharing chokes - OTLX0X

Up to output frequencies of 300 Hz, 1 m/s airflow provides adequate cooling.

Above 300 Hz, the following equation must be used to calculate the required airflow:

0.75

S = (f

Where:

Example:

Output frequency is 450 Hz

S = (450 = 1.4 m/s

Dual OTL output sharing chokes - OTLX1X

The OTLX1X dual output sharing choke core does not see the change in drive output frequency as this choke is a current cancelling choke. Only the drives switching frequency has an affect on the core loss.

Therefore motor frequency is not an issue until higher frequencies cause high copper losses due to skin effect.

Therefore with the dual OTL chokes, only 1 m/s airflow is required.

Maximum output frequency for OTL chokes

The maximum allowable output frequency for OTL output sharing chokes, singles or duals, should be limited to 1000 Hz.

6.4 Supplying the Unidrive M/Unidrive HS size 9A, 9D, 10D and 11D drives with DC / DC bus paralleling

The drive may be supplied with DC instead of 3 phase AC.

The connecting of the DC bus between several drives is typically used to:

1. Return energy from a drive which is being overhauled by the load to a second motoring drive.

2. Allow the use of one braking resistor to dissipate regenerative energy from several drives.

There are limitations to the combinations of drives which can be used in this configuration.

For further information, contact the supplier of the drive.

It is not possible to supply Unidrive M/Unidrive HS size 9E/T, 10E/T and 11E/T drives with DC due to the lack of an accessible negative DC terminal.

6.5 Heatsink fan supply

When operating on normal mains supply the heatsink fan on all drive sizes is supplied internally by the drive. When operating in low voltage mode it is necessary to connect an external 24V supply to terminal 61 and 62 if heatsink fan operation is required. Please see section 6.7 Low voltage operation on page 98 for more details.

6.6 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 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 9 and larger, 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. The location of the power 24 Vdc can be identified from Figure 6-16 Location of the 24 Vdc power supply connection on size 9 to 11 on page 97

6.7 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 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 9 to 11

Minimum continuous operating voltage: 26 V

Minimum start up voltage: 32 V

Maximum over voltage trip threshold: 230 V drives: 415 V

400 V drives: 830 V

575 V drives: 990 V

690 V drives: 1190 V

It is not possible to supply Unidrive M/Unidrive HS size 9E/T, 10E/T and 11E/T drives with DC due to the lack of an accessible negative DC terminal.

In low voltage mode only, with frame size 9 to 11, a 24 V supply needs to be provided for the heatsink fan. The fan supply should be connected to terminal 61 and 62.

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 supply fault current given in Table 6-10.

Model Symmetrical fault level (kA)

All sizes 100

Fuses

The AC supply to the drive must be installed with suitable protection against overload and short-circuits. Table 6-11 shows recommended fuse ratings. Failure to observe this requirement will cause risk of fire.
