enINSTALLATION AND MAINTENANCE


NOTE

LEROY-SOMER reserves the right to modify the characteristics of its products at any time in order to incorporate the latest

technological developments. The information contained in this document may therefore be changed without notice.

CAUTION

For the user's own safety, this variable speed drive must be connected to an approved earth terminal).

If accidentally starting the installation is likely to cause a risk to personnel or the machines being driven, it is essential to complywith the power connection diagrams recommended in this manual.

The variable speed drive is tted with safety devices which, in the event of a problem, control stopping and thus stop the motor. The

motor itself can become jammed for mechanical reasons. Voltage uctuations, and in particular power cuts, may also cause the

motor to stop. The removal of the causes of the shutdown can lead to restarting, which may be dangerous for certain machines or

installations.In such cases, it is essential that the user takes appropriate precautions against the motor restarting after an unscheduled stop.

The variable speed drive is designed to be able to supply a motor and the driven machine above its rated speed.

If the motor or the machine are not mechanically designed to withstand such speeds, the user may be exposed to serious dangerresulting from their mechanical deterioration.

Before programming a high speed, it is important that the user checks that the installation can withstand it.

The variable speed drive which is the subject of this manual is designed to be integrated in an installation or an electrical machine,

and can under no circumstances be considered to be a safety device. It is therefore the responsibility of the machine manufacturer,

the designer of the installation or the user to take all necessary precautions to ensure that the system complies with current

standards, and to provide any devices required to ensure the safety of equipment and personnel.

LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.

........................................

This manual only describes the general features, characteristics and installation of the POWERDRIVE MD2S. For

commissioning, refer to manual ref. 4617.

SAFETY AND OPERATING INSTRUCTIONS FOR VARIABLE SPEED DRIVES

(In accordance with the low voltage directive 2006/95/EC)

Throughout the manual, this symbol warns of

consequences which may arise from inappropriate

use of the drive, since electrical risks may lead to material

or physical damage as well as constituting a re hazard.

1 - General

Depending on their degree of protection, the variable speed

drives may contain unprotected live parts, which may be moving

or rotating, as well as hot surfaces, during operation.

Unjustied removal of protection devices, incorrect use, faulty

installation or inappropriate operation could represent a seriousrisk to personnel and equipment.

For further information, consult the documentation.

All work relating to transportation, installation, commissioning

and maintenance must be performed by experienced, qualied

personnel (see IEC 364, CENELEC HD 384 or DIN VDE 0100,as well as national specications for installation and accidentprevention).

In these basic safety instructions, qualied personnel means

persons competent to install, mount, commission and operate

the product and possessing the relevant qualications.

2 - Use

Variable speed drives are components designed for integration

in installations or electrical machines.

When integrated in a machine, commissioning must not take

place until it has been veried that the machine conforms

with directive 2006/42/EC (Machinery Directive). It is alsonecessary to comply with standard EN 60204, which stipulates

in particular that electrical actuators (which include variablespeed drives) cannot be considered as circuit-breaking devices

and certainly not as isolating switches.

Commissioning can take place only if the requirements of the

Electromagnetic Compatibility Directive (EMC 2004/108/EC)are met.

The variable speed drives meet the requirements of the Low

Voltage Directive 2006/95/EC. The harmonised standards

of the DIN VDE 0160 series in connection with standard VDE

0660, part 500 and EN 60146/VDE 0558 are also applicable.

The technical characteristics and instructions concerning theconnection conditions specied on the nameplate and in the

documentation provided must be observed without fail.

3 - Transportation, storageAll instructions concerning transportation, storage and correct

handling must be observed.The climatic conditions specied in the technical manual must

be observed.

4 - Installation

The installation and cooling of equipment must comply with thespecications in the documentation supplied with the product.

The variable speed drives must be protected against any

excessive stress. In particular, there must be no damage to

parts and/or modication of the clearance between components

during transportation and handling. Avoid touching the electronic

components and contact parts.The variable speed drives contain parts which are sensitive to

electrostatic stresses and may be easily damaged if handled

incorrectly. Electrical components must not be exposed to

mechanical damage or destruction (risks to health!).

5 - Electrical connection

When work is performed on variable speed drives which arepowered up, the national accident prevention regulations must

be respected.

The electrical installation must comply with the relevant

specications (for example conductor cross-sections, protection

via fused circuit-breaker, connection of protective conductor).

More detailed information is given in the documentation.Instructions for an installation which meets the requirements

for electromagnetic compatibility, such as screening, earthing,

presence of lters and correct insertion of cables and

conductors, are given in the documentation supplied with the

variable speed drives. These instructions must be followed

in all cases, even if the variable speed drive carries the CE

mark. Adherence to the limits given in the EMC legislation isthe responsibility of the manufacturer of the installation or the

machine.

6 - Operation

Installations in which variable speed drives are to be integrated

must be tted with additional protection and monitoring

devices as laid down in the current relevant safety regulations,

such as the law on technical equipment, accident prevention

regulations, etc. Modications to the variable speed drives

using control software are permitted.Active parts of the device and the live power connections must

not be touched immediately after the variable speed drive is

powered down, as the capacitors may still be charged. In view

of this, the warnings xed to the variable speed drives must beobserved.

Permanent magnet motors generate electrical energy whilethey are rotating, even when the drive is switched off. In this

case, the drive continues to be powered by the motor terminals.

If the load is capable of turning the motor, a switching device

must be provided upstream of the motor to isolate the drive

during maintenance operations.During operation, all doors and protective covers must be kept

closed.

7 - Servicing and maintenance

Refer to the manufacturers documentation.

See the Maintenance section in this document.

This manual is to be given to the end user.

Measuring the temperature of the power bridges in

conjunction with thermal modelling of the IGBTs protects the

POWERDRIVE MD2S against overheating.

At low motor frequencies, IGBT modules are subject to tough

temperature cycling, which may reduce their life time. To

prevent this risk, the curve opposite indicates the derating for

output currents Ico and Imax when operating at low motor

frequency in continuous operation.

Variable speed driveCONNECTIONS

3 - CONNECTIONS

All connections work must be performed by

qualied electricians in accordance with the laws in

force in the country in which the drive is installed. This

includes earthing to ensure that no directly accessiblepart of the drive can be at the mains voltage or any other

voltage which may be dangerous.

The drive must be supplied through an approved

circuit-breaking device so that it can be powered down

safely.

The optional isolator supplied with the drive doesnot isolate the drive input busbars. It must without

fail be associated with a circuit-breaking device in the

switchboard.

The drive power supply must be protected against

overloads and short-circuits.

Check that the voltage and current of the drive, the

motor and the mains supply are compatible. The voltages on the connections of the mains supply,

the motor, the braking resistor or the lter may cause

fatal electric shocks. The protective plates supplied with

the drive must always be installed correctly to protect theuser against electric shocks.

Only one permanent magnet motor can be connected

to the drive output. It is recommended to install a circuit-

breaking device between the permanent magnet motor

and the drive output to eliminate the risk of hazardous

voltage feedback when performing maintenance work. See also the recommendations in section 7.

Disconnection of forced ventilation units

The fuse board described in section 3.1.1. enables the user to

switch off the power supply to the drive forced ventilation units

momentarily, if preheating resistors are used in the cabinet for

example.To disconnect the fans, remove the jumper connecting

terminals P7 and P8 and connect a normally closed contact

(230 V/7 A on resistive load). A closed contact allows the

ventilation units to operate, an open delayed contact cuts off

their power supply (delay 10 minutes for ambiant temperatureup to 40C, otherwise 30 minutes).

3.1.4 - Cables and fuses

It is the responsibility of the user to connect and provide protection for the POWERDRIVE MD2S in accordance

with the current legislation and regulations in the country of use. This is particularly important with regard to the

size of the cables, the type and rating of fuses, the earth or ground connection, powering down, acknowledging trips,

isolation and protection against overcurrents.

The installation must have a short circuit current (Isc) > 20 ILat the point of drive connection.

This table is given for information only, and must under no circumstances be used in place of the current standards.

current.

(1) gG fuse or equivalent solution (fuses connected in parallel, preferably C type circuit-breaker, etc). This protection must always

be connected in series with aR semi-conductor fuses.

(2) Semiconductor aR fuses do not ensure the protection of the drive power supply line and must always be associated with a

protection device against overload, localized at the head of the line.

(3) The recommended mains cable cross-sections have been determined for single-core cable with a maximum length of 20 m. For

longer cables, take line voltage drops into consideration due to large cable length.

(4) The motor cable cross-sections are given for information only for a current corresponding to the value of the

Ico current at 3 kHz, a maximum length of 50 m, output frequency less than 100 Hz and an ambient temperature of40C. The recommended motor cables are shielded multicore type(see section 4.5.2). The values supplied

are typical values.

Example: Cable cross-section of 3 x (3 x 185 + 95) corresponds to 3 cables each consisting of 3 phase conductors

(cross-section 185 mm) + earth conductors (cross-section 95 mm).

3.2 - Connection of the control

The POWERDRIVE MD2S inputs have a positive

logic conguration. Using a drive with a control system

which has a different control logic may cause unwantedstarting of the motor.

The POWERDRIVE MD2S control circuit is isolated from

the power circuits by single insulation. Its electronic 0V

is connected to the connection terminal on the outer

protective conductor (earth terminal). The installer must

ensure that the external control circuits are isolatedagainst any human contact.

If the control circuits need to be connected to circuits

conforming to SELV safety requirements, additional

insulation must be inserted to maintain the SELV

classication (see EN 61140).

3.3 - STO-1/STO-2 inputs: Safe Torque Off

function

The STO-1 and STO-2 inputs are safety inputs that can be

used to disable the drive output so no torque at the motorshaft is provided.

They are independent of one another. They are created bysimple hardware not connected to the microcontroller. They

acts on two different stages of the IGBT output bridge control.

To enable the drive, the STO-1 and STO-2 inputs must be

connected to the +24V source.

The opening of, at minimum, one of the inputs locks the

output bridge.

These 2 inputs can be used in conjunction to create a "Safe

Torque Off" function with a logic combining 2 separate

channels.

In this conguration, the "Safe Torque Off" function is

guaranteed with a very high level of integrity in conformitywith standards:

- EN 61800-5-2

- EN/ISO 13849-1: 2006; PLe

- IEC/EN 62061: 2005; SIL3

(CETIM approval no. CET0047520)

In a safety system, this built-in function enables the drive to

act as a substitute for a contactor so the motor can run in

freewheel mode.

The STO-1 and STO-2 inputs are compatible with self-testedlogic outputs in controllers such as PLCs, for which the test

pulse lasts for 1 ms maximum.

If the data sent by the 2 inputs is not identical, this generates

a drive trip. The RL1 relay opens and the drive indicates

a "t.r./63" trip on the drive 2-digit display or "STO input

inconsistency" trip on the parameter-setting interface.

For correct use, the power and control connection diagrams

described in the following paragraphs must be adhered to.

The STO-1/STO-2 inputs are safety components

which must be incorporated in the complete

system dedicated to machine safety. As for any

installation, the complete machine must be subject to a

risk analysis. The integrator must determine the safety

category which the installation must comply with. The STO-1 and STO-2 inputs, when open, lock the

drive, so the dynamic braking function is no longer

available. If a braking function is required before the

drive secure disable lock is applied, a time-delayed

safety relay must be installed to activate the locking

automatically after the end of braking.If braking needs to be a machine safety function, it must

be provided by an electromechanical solution since the

dynamic braking by the drive function is not considered

as a secure disable function.

The STO-1/STO-2 inputs do not provide theelectrical isolation function. Prior to any work carry out

on tre drive/installation, the power supply must therefore

be switched of an approved isolating device (isolator,switch, etc).

Variable speed driveGENERAL EMC - HARMONICS - MAINS INTERFERENCE

4.4.2 - Mains transient overvoltages

There are numerous sources of overvoltages on an electricalinstallation:

Connection/disconnection of banks of power factor

correction capacitors High-power thyristor-controlled equipment (oven, DC drive,

etc)

Results of lighning

4.4.2.1 - Connection/disconnectionofabankofpowerfactor

correction capacitors

Connecting power factor correction capacitors in parallel on

the drive power supply line when the drive is running cangenerate transient overvoltages that are likely to trip the drive

safety devices, or even damage it in extreme cases.

If banks of power factor correction capacitors are used on the

power supply line, make sure that:

The threshold between steps is low enough to avoidcausing overvoltage on the line The capacitors are not permanently connected

4.4.2.2 - Presence of commutation notches on the line

When high-power thyristor-controlled equipment is connected

on the same line as the drive, it is essential to ensure that

the harmonics generated by the commutation notches do

not excessively distort the mains voltage and do not create

voltage peaks with amplitude higher than 2 x mains Vrms. If

this is the case, it is essential to take corrective measures byinserting a choke in the line supplying the thyristor-controlled

equipment or by moving the drive power supply line to

another source.

4.4.3 - Unbalanced power supply

Similar to what is observed on an electric motor, the linecurrent imbalance of a drive operating on an unbalanced

mains supply may be several times the value of the

voltage imbalance measured on the power supply. A highly

unbalanced mains supply (>2%) associated with a low

mains impedance may result in a high level of stress on the

components at the input stage of a drive.Additional mains chokes can be installed upstream of a

POWERDRIVE MD2S supplied by an unbalanced mains

in order to reduce the current imbalance factor (see

characteristics in section 5.4).

4.4.4 - Ground connections

The equipotential earth bonding of some industrial sites

is not always observed. This lack of equipotentiality leads

to leakage currents which ow via the earth cables (green/

yellow), the machine chassis, the pipework, etc, and alsovia the electrical equipment. In some extreme cases, these

currents can trip the drive.

It is essential that the earth network is designed and

implemented by the installation supervisor so that its

impedance is as low as possible, so as to distribute the fault

currents and high-frequency currents without them passingthrough electronic equipment.

Metal grounds must be mechanically connected to each other

with the largest possible electrical contact area. Under no

circumstances can the earth connections designed to protectpeople, by linking metal grounds to earth via a cable, serve as

a substitute for the ground connections (see IEC 61000-5-2).

The immunity and radio-frequency emission level are directly

linked to the quality of the ground connections.

4.5 - Basic precautions for installation

These should be taken into account when wiring the cabinet

and the external components. In each paragraph, they are

listed in decreasing order of effect on correct operation of theinstallation.

4.5.1 - Wiring inside the cabinet

- Do not run the control cables and the power cables in the

same cable ducts.

- For control cables, use shielded twisted cables.

4.5.2 - Wiring outside the cabinet

Connect the motor earth terminal directly to that of

the drive.

It is recommended that a shielded symmetrical cable is

used: three phase conductors and three PE conductors

arranged symmetrically.

U

WV

PE

PE PE

Shielding

A separate PE protective conductor is mandatory if the

conductivity of the cable shielding is less than 50% of the

conductivity of the phase conductors.

- The shield must be connected at both ends: drive end and

motor end (connected round the whole circumference).- In the second industrial environment, the shielded motor

power supply cable can be replaced by a 3-core + earth

cable placed in a fully enclosed metal conduit (metal cable

duct for example). This metal conduit must be mechanically

connected to the electrical cabinet and the structure

supporting the motor.

If the conduit consists of several pieces, these should be

interconnected by braids to ensure earth continuity. The

cables must be positioned and held in a cloverleaf formationin the conduit.

U

WVPE

EMCbraid

Clamp

- There is no need to shield the power supply cables between

the mains supply and the drive.

- Isolate the power cables from the control cables. The powercables must intersect the other cables at an angle of 90.

- Isolate sensitive elements (probes, sensors, etc) from metal

structures which may be shared by the motor support.
