Variable speed motor or geared motor

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 VARMECA 30 motor must be connected to an approved earth ( terminal). If accidentally starting the installation is likely to cause a risk to p ersonnel or the machines being driven, it is essential to supply the equipment via a circuit-breaking device (power contactor) which can be controlled via an external safety system (emergency stop, detection of errors on the installation).

The VARMECA 30 motor is fitted with safety devices which, in the event of a fault, control stopping and thus stop the motor. The motor itself can become jammed for mechanical reasons. Voltage fluctuations, and in particular power cuts, may al so 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 danger resulting from their mechanical deterioration. It is important that the user checks that the installation can withstand it, before programming a high speed. 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 th e above recommendations not being observed.

Variable speed motor or geared motor

SAFETY AND OPERATING INSTRUCTIONS FOR ELECTRICAL ACTUATORS (In accordance with the low voltage directive 73/23/EEC modified by 93/68/EEC)

• Throughout the manual, this symbol warns of

consequences which may arise from inappropriate use of the VARMECA 30, since electrical risks may lead to material or physical damage as well as constituting a fire hazard.

1 - General

Depending on their degree of protection, VARMECA 30 motors may contain moving parts, as well as hot surfaces, during operation. Unjustified removal of protection devices, incorrect use, faulty installation or inappropriate operation could represent a serious risk to personnel and equipment. For further information, consult the manual. All work relating to transportation, installation, commissioning and maintenance must be performed by experienced, qualified personnel (see IEC 364 or CENELEC HD 384, or DIN VDE 0100 and national specifications for installation and accident prevention). In these basic safety instructions, qualified personnel means persons competent to install, mount, commission and operate the product and possessing the relevant qualifications.

2 - Use

VARMECA 30 motors are components designed for integration in installations or electrical machines. When integrated in a machine, commissioning must not take place until it has been verified that the machine conforms with directive 89/392/EEC (Machinery Directive). It is also necessary to comply with standard EN 60204, which stipulates in particular that electrical actuators (which include VARMECA 30) cannot be regarded as circuit-breaking devices and certainly not as isolating switches. Commissioning can take place only if the requirements of the Electromagnetic Compatibility Directive (89/336/EEC, modified by 92/31/EEC) are met. VARMECA 30 motors meet the requirements of the Low Voltage Directive 73/23/EEC, modified by 93/68/EEC. The harmonised standard 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 the connection conditions specified on the nameplate and in the documentation provided must be observed without fail.

4 - Installation

The installation and cooling of equipment must comply with the specifications in the manual supplied with the product. VARMECA 30 motors must be protected against excessive stress. In particular, there must be no damage to parts and/or modification of the clearance between components during transportation and handling. Avoid touching the electronic components and contact parts. VARMECA 30 motors contain parts which are sensitive to electrostatic stress 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 VARMECA 30 motors which are powered up, national accident prevention specifications must be respected. The electrical installation must comply with the relevant specifications (for example conductor cross-sections, protection via fused circuit-breaker, connection of protective conductor). More detailed information is given in the manual. Instructions for an installation which meets the requirements for electromagnetic compatibility, such as screening, earthing, presence of filters and correct insertion of cabl es and conductors, are given in the documentation supplied with the VARMECA 30. These instructions must be followed in all cases, even if the VARMECA 30 carries the CE mark. Adherence to the limits given in the EMC legisl ation is the responsibility of the manufacturer of the installation or the machine.

6 - Operation

Installations incorporating VARMECA 30 motors must be fitted with additional protection and monitoring devices as laid down in the current relevant safety regulations: law on technical equipment, accident prevention regulations, etc. Modification of VARMECA 30 motors using control software is permitted. Active parts of the device and live power connections must not be touched immediately after the VARMECA 30 is powered down, as the capacitors may still be charged. In view of this, the warnings fixed to VARMECA 30 motors must be observed. During operation, all protective covers must remain closed.

3 - Transportation, storage

All instructions concerning transportation, storage and correct handling must be observed. The climatic conditions sp ecified in the technica l manual must be observed.

7 - Servicing and maintenance

Refer to the manufacturer’s documentation.

1.5 - Radio-frequency interference

1.5.1 - General

Variable speed drives use high-speed switches (transistors, semi-conductors) which switch high voltages (around 550VDC for 3-phase drives) at high frequencies (several kHz). This provides better efficiency and a low level of motor noise.

As a result, they generate radio-frequency signals which may disturb operation of other equipment or distort measurements taken by sensors:

- due to high-frequency leakage currents which escape to earth via the stray capacity of the drive/motor cable and that of the motor via the metal structures which support the motor

- by conduction or feedback of R.F. signals on the power supply cable: conducted emissions

- by direct radiation near to the mains supply power cabl e or the drive/motor cable: radiated emissions These phenomena are of direct interest to the user. The frequency range concerned (radio frequency) does not affect the energy distribution company.

Conformity of the drive is only assured when the mechanical and electrical installation instructions

described in this manual are adhered to.

1.5.4 - Earth leakage current

Earth leakage currents may depend on the type of EMC filter used. The VARMECA 30 can be supplied with its filter integrated and wired-up. The levels of leakage current also depend on the voltage and/or the power supply frequency and the size of the motor. In all cases, for conformity with immunity standards, a voltage limiting device is connected to earth. The shunt current is negligible in normal circumstances.

1.5.4.1 - use of earth leakage detector (residual current device)

1- Type AC: which detects AC faults. Not to be used with variable speed drives. 2- Type A: which detects AC faults and pulsed DC faults (provided that the DC is cancelled out at least once per cycle). Only for use with single-phase drives. 3 - Type B: which detects AC faults, pulsed DC faults and smoothed DC faults. Only this type is suitable for use with

all variable speed drives.

Note: If an external EMC filter is being used, a delay of 50 ms should be incorporated to avoid spurious faults being taken into account.

1.5.5 - Control cable immunity

Control cable immunity can be increased outside the VARMECA 30 by one of the following 2 methods:

• Use of shielded twisted pair cable, with shielding connected to earth around its circumference within 100 mm of the VARMECA 30.

• Passing the cable through a ferrite ring at 100 mm maximum distance from the VARMECA 30.

Note: Several control cables can pass through a single ferrite.

1.5.6 - Control circuit immunity when overvoltage occurs

Immunity to overvoltages in control circuits or in long cables connected to the outside of a building. The various drive input and output circuits conform to standard EN61000-6-2 (1 kV) relating to overvoltages.

There are some exceptions, where the installation may be exposed to overvoltage peaks which exceed the levels determined by the standard. This may be the case in the event of lightning strikes or earth faults associated with long cable lengths (>30 m). To limit the risks of damage to the drive, the following precautions could be taken:

- Galvanic isolation of the I/O.

- Duplication of the cable shielding with an earth wire of

10 mm must be linked at both ends and connected to earth with the shortest possible connection. This stratagem enables high currents to pass into the earth wire, rather than into the shielding

- Reinforcement of the logic and analogue I/O protection by adding a zener diode or a peak limiter.

Elimination of uni-directional logic and analogue I/O overvoltages

minimum. The cable shielding and the earth wire

These circuits are available in modules (DIN rail mounting). These circuits are not suitable for encoder signals or for highspeed logic data networks, because the diodes may affect the signal. The majority of encoders have galvanic isolation between the motor casing and the encoder circuit, and in this case, no precautions are necessary. For data networks, follow the specific network recommendations.

If a logic output is subjected to significant overvoltages, the drive trips on an "Old1" fault.

1.6 - Description of cables and protection devices

• It is the responsibility of the user to connect and provide protection for the VARMECA 30 in accordance with the

legislation and regulations in force in the country of use. This is particularly important as regards the size of cables, the type and rating of fuses, the earth or ground connection, powering down, acknowledging faults, insulation and protection against overcurrents.

• These tables are given for information only, and must under no circumstances be used in place of the current standards.

• When using a circuit-breaker, it must be a motor circuit-brea ker (D curve).

• The residual current device must be type B. Too many devices connected to a single residual current device can cause it to trip. Check that the circuit-breaker is only protecting the VARMECA.

• Comply with the size of protection fuses.

2 - INSTALLATION

• It is the responsibility of the owner or user to

ensure that the installation, operation and maintenance of the drive and its options comply with legislation relating to the safety of people and equipment and with the regulations in force in the country of use.

• Before carrying out any work, disconnect and lock the drive power supply. For the single-phase range, wait 2 minutes to make sure that the capacitors have discharged.

• After connection, ensure that the seals are firmly in place, and that the screws and cable glands are watertight to ensure IP 65 protection.

• Holes are provided at the lowest points of the enclosure, depending on the operating position, to drain off any moisture that may have accumulated inside during cooling of the machine. In conditions which encourage the formation of con de nsation, it is advisable to leave the drain holes permanently open.

3 - CONNECTIONS

• All connection work must be performed in

accordance with the laws in force in the country where the drive is installed. This includes earthing to ensure that no directly accessible part of the drive can be at the mains voltage or any other v oltage which may be dangerous.

• The voltages on the cables or connections of the mains supply, the motor, the braking resistor or the filter may cause fatal electric shocks. Contact must be avoided in all circumstances.

• The drive must be supplied via a circuit-breaking device so that it can be powered down safely.

• The drive contains capacitors which remain charged at a fatal voltage even after the power supply has be en cut off.

• Wait 2 minutes after powering down the drive before removing the protection devices.

• The drive power supply must be protected against overloads and short-circuits.

• It is vital to respect the rating of protection devices.

• Connection with copper conductor only.

• Check that the voltage and current of the drive, the motor and the mains supply are compa t ible.

• After the drive has been operating, the hea tsink or the braking resistors may be very hot (avoid touching them).

• When the cover is open, the VARMECA 30 degree of protection is IP10. Any work should only be carried out by experienced, qualified personnel.

2.1 - General

The VARMECA 30 motor is fitted to the machine like a standard motor, with flange or foot mounting. The motor ventilation cools the whole assembly. Make sure that the ventilation air inlet is free of obstruction. The positions of the potentiometer/cable gland supports are specified at the time of ordering. However they may be reversed if necessary.

• Check that the different earth points are actually at the same voltage.

• Incorporate a bend where the cables enter the cable glands so that water cannot penetrate the terminal box.

• Tighten the cable gland firmly.

• The VARMECA 30 has a positive logic

configuration. Using a drive with a control system which has a different control logic may cause unwanted starting of the motor.

• The control circuits in the drive are isolated from the power circuits by single insulation (IEC 664-1). The installer must ensure that the external control circuits are isolated against 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 classification.

3.1 - Wiring precautions

• When the VARMECA 30 is controlled remotely, avoid parallel routing of power cables and control cables.

• All remote control cables must be shielded and have a cross-section between 0.22 mm should be connected to earth at both ends.

3.5.2 - Connection diagram with safety input

3.5.2.1 - Safety input

This input, when opened, causes the drive to lock. Independent of the microprocessor, it acts on several levels of control from the power bridge. It is designed in such a way that even if one or more circuit components were to fail, the absence of torque on the motor shaft is guaranteed with a very high level of integrity.

This input is used to create a safety function using the principles of category 1 or 3 of standard EN954-1, depending on the application diagram.

The design of the "freewheel stop" function using input SDI2 has been evaluated by CETIM.

The results of this examination are recorded in report no. 732773/47A.

This built-in functionality enables the drive to act as substitute for a contactor in order to stop the motor in freewheel mode.

By using this safety input redundantly with another drive logic input, a diagram can be used which is ca pable of resisting a single fault. The drive will stop the motor in freewhee l mode using two different control channels.

For correct use, the power connection diagrams described in the following paragraphs must be adhered to.

To unlock the drive and provide the safety function , safety input ENA (VMA 31/32) or SDI2 (VMA 33/34) must be connected to the +24V source (SDI1 for VMA 33/34).

This +24V source should be reserved exclusively for the safety input function (VMA33/34).

• The safety input is a safety component which

must be incorporated into the complete system dedicated to machine safety. As for any installation, the complete machine must be the subject of a risk analysis by the integrator which will determine the safety category with which the installation must comply.

• The safety input, when open, locks the drive, mean ing the dynamic braking function i s no longer avai lable. If a braking function is required before the drive safety lock is applied, a time-delayed safety relay should be installed to activate locking automatically after the end of braking. If braking needs to be a machine safety function, it should be provided by an electromechanical solution since the dynamic braking by the drive function is not considered to be a safety function.

• The safety input does not provide the electrical isolation function. Before any work is carried out, the power supply must be cut by an approved isolating device (isolator, switch, etc).

• The safety function is not enabled when the drive is controlled via the keypad or via a fieldbus.

Using the safety input means the motor can be stopped in freewheel mode without using a l ine contactor. The drive’s internal principles are sufficiently safe to perform a stop using the safety input directly (category 1 of EN954-1).

COMMISSIONING

3776 en - 07.2007 / h

4 - COMMISSIONING

• Before switching on the VARMECA 30, check that the electrical connections are correct, and that any

moving parts are mechanically protected.

• For the safety of personnel, the VARMECA 30 must not be switched on with the protective cover removed.

4.1 - Starting with the power supply

Since the run command has been factory-enabled via a jumper, the motor starts as soon as it is switched on. The speed is adjusted with the local control knob (B 31/32 or B 33/34 option) or a remote reference (0-10 V or 4-20 mA). Power-up: the green indicator lamp is lit continuously. The control terminals SDI1 and SDI2 (VMA 33/34) or 1 1 and 12 (VMA 31/32) are linked (unlocking).

4.1.1 - Automatic starting

By leaving the wire between control terminals 8 and 11 (VMA 31/32) or DI2 and +24V (VMA 33/34), the motor starts running forward.

4.2 - Starting with remote volt-free contact

Once it has been switched on, the motor starts in accordance with the run command given by the closing of the vol t-free contact corresponding to the desired direction of rotation. The speed is adjusted with the local control knob (B 31/32 or B 33/34 option) or a remote reference (0-10 V or 4-20 mA).

4.3 - Starting with local run/stop control (BMA 31/32, BMA 33/34 or BMAVAR 31/32, BMAVAR 33/34 option)

Once it has been switched on, the motor starts after the control knob corresponding to the desired direction of rotation has been pressed for one second. The speed is only adjusted with the local control knob.

4.4 - Setting the speed

4.4.1 - External reference

Adjust the speed reference using the chosen reference (0/10 V or 4/20 mA).

4.4.2 - Control knob options (B 31/32 or B 33/34) and remote potentiometer option

Adjust the speed reference using the control knob or the 10 kΩ remote potentiometer.

4.4.3 - Internal speed control option (CVI VMA 31/32 or CVI BMA 33/34)

Adjust the speed reference using the Int. Spd. potentiometer. Adjust the Max. Spd. or Min. Spd. potentiometers if it is not possible to reach the desired speed.

No trip Mains present

IGBT temperature alarm Motor overload Braking resistor option overload

• Check that the motor is not overloaded or stalled

• Check that air is able to circulate around the motor fins and VARMECA casing

• The motor is overloaded: check the motor current using a clamp ammeter

• Check that the deceleration ramp is long enough for applications with high inertia

• Short-circuit of a motor winding

• Locked motor rotor

• Faulty insulation of a winding

Steady red

The fault is cleared by switching off the VARMECA 30 or by opening/closing the co nnection between terminals 12: ENA and 11: +24 V (VMA 31/32) or SDI1 and SDI2 (VMA 33/34).

6 - MAINTENANCE

• All work relating to installation, commissioning and maintenance must be carried out by

experienced, qualified person nel.

• Before carrying out any work, disconnect an d lock the VARMECA 30 power supply circuit and wait 2 minutes for the capacitors to discharge.

6.1 - Care

No special care is required on the VARMECA 30, apart from the regular removal of dust from the fan grille and the cooling fins located at the bottom of the casing. Do not dismantle the VARMECA 30 while it is still under guarantee, as this would then imme diately become null and void.

CAUTION:

Certain components which are sensitive to electrostatic discharge may be destroyed simply by touching them. Do not leave any metal object in the connection area, as this could cause a short-circuit.

• I

t overheating

• Internal fault

• Undervoltage

• Overvoltage

The motor current IS NOT MEASURED ON THE VARMECA 30 POWER SUPPLY (L1, L2, L3). It is measured using an ordinary clamp ammeter on one of the wires which goes into the motor terminal block.

6.2.2 - Procedure for measuring the motor current on VMA 31/32 (if the motor wire loop is inaccessible)

- Open the VARMECA 30 power supply circuit and lock it.

- Wait 2 minutes for the capacitors to discharge (for the single-phase range).

- Open the cover of the VARMECA 30.

- Open the connection between terminals SDI1 and SDI2 (VMA 33/34) or 11 and 12 (VMA 31/32).

- Remove the TORX + slot type screws from the protection plate above the motor terminals.

- Pass the longest motor wire along the side of the protection circuit.

- Replace the protection plate and fasten it.

- Pass the clamp ammeter through the motor wire loop.

- Remake the connection between terminals SDI1 and SDI2 (VMA 33/34) or 11 and 12 (VMA 31/32).

• Check that no incident has occurred

• Switch off and then on again to clear the fault.

• Check the mains voltage

• Check that the deceleration ramp is long enough for applications with high inertia

• If the fault remains, consult LEROYSOMER
