NOTE: Please also refer to the Programming Manual.

When the drive is powered up, the power components and some of the control components are connected to the line supply. It is extremely dangerous to touch them. The drive cover must be kept closed.

In general, the drive power supply must be disconnected before any operation on either the electrical or mechanical parts of the installation or machine.

After the ATV has been switched off and the display has disappeared completely, wait for 10 minutes before working on the equipment. This is the time required for the capacitors to discharge.

The motor can be stopped during operation by inhibiting start commands or the speed reference while the drive remains powered up. If personnel safety requires prevention of sudden restarts, this electronic locking system is not sufficient: fit a cut-off on the power circuit..

The drive is fitted with safety devices which, in the event of a fault, can shut down the drive and consequently the motor. The motor itself may be stopped by a mechanical blockage. Finally, voltage variations, especially line supply failures, can also cause shutdowns.

If the cause of the shutdown disappears, there is a risk of restarting which may endanger certain machines or installations, especially those which must conform to safety regulations.

In this case the user must take precautions against the possibility of restarts, in particular by using a low speed detector to cut off power to the drive if the motor performs an unprogrammed shutdown.

The drive must be installed and set up in accordance with both international and national standards. Bringing the device into conformity is the responsibility of the systems integrator who must observe the EMC directive among others within the European Union.

The specifications contained in this document must be applied in order to comply with the essential requirements of the EMC directive.

The ATV 31 must be considered as a component: it is neither a machine nor a device ready for use in accordance with European directives (machinery directive and electromagnetic compatibility directive). It is the responsibility of the end user to ensure that the machine meets these standards.

The drive must not be used as a safety device for machines posing a potential risk of material damage or personal injury (lifting equipment, for example). In such applications, overspeed checks and checks to ensure that the trajectory remains under constant control must be made by separate devices which are independent of the drive.

The products and equipment described in this document may be changed or modified at any time, either from a technical point of view or in the way they are operated. Their description can in no way be considered contractual.

(1)These power ratings and currents are for a maximum ambient temperature of 50°C and a switching frequency of 4 kHz in continuous operation.The switching frequency is adjustable from 2 to 16 kHz.

Above 4 kHz, the drive will reduce the switching frequency in the event of excessive temperature rise. The temperature rise is controlled by a PTC probe in the power module. Nonetheless, the nominal drive current should be derated if operation above 4 kHz needs to be continuous.

Derating curves are shown on page 6 as a function of switching frequency, ambient temperature and mounting conditions.

Wiring recommendations

Power

The drive must be earthed to conform with the regulations concerning high leakage currents (over 3.5 mA).

When upstream protection by means of a "residual current device" is required by the installation standards, a type A device should be used for single-phase drives and type B for 3-phase drives. Choose a suitable model incorporating:

•HF current filtering

•A time delay which prevents tripping caused by the load from stray capacitance on power-up. The time delay is not possible for 30 mA

devices. In this case, choose devices with immunity against accidental tripping, for example RCDs with reinforced immunity from the s.i range (Merlin Gerin brand).

If the installation includes several drives, provide one "residual current device" per drive.

Keep the power cables separate from circuits in the installation with low-level signals (detectors, PLCs, measuring apparatus, video, telephone).

If you are using cables > 50 m between the drive and the motor, add output filters (please refer to the catalogue).

Control

Keep the control circuits away from the power cables. For control and speed reference circuits, we recommend using shielded twisted cables with a pitch of between 25 and 50 mm, connecting the shielding to ground at each end.

Wiring

Operation on an IT system

IT system: Isolated or impedance earthed neutral.

Use a permanent insulation monitor compatible with non-linear loads (a Merlin Gerin type XM200, for example).

A ATV 31pppM2 and N4 drives feature built-in RFI filters. These filters can be isolated from ground for operation on an IT system as follows:

ATV31H018M2 to U22M2 and ATV31H037N4 to U40N4:

Pull out the jumper on the left of the ground terminal as illustrated below.

Wiring

Electromagnetic compatibility

Principle

• Grounds between the drive, motor and cable shielding must have "high frequency" equipotentiality.

• Use shielded cables with shielding connected to ground throughout 360° at both ends for the motor cable 6, braking resistor (if used) 8, A and control-signalling cables 7. Metal ducting or conduit can be used for part of the shielding length provided that there is no break in continuity.

• Ensure maximum separation between the power supply cable (line supply) and the motor cable.

3Non-shielded power supply wires or cable

4Non-shielded wires for relay contacts

5Fix and ground the shielding of cables 6, 7 and 8 as close as possible to the drive:

-Strip the shielding.

-Use stainless steel cable clamps of an appropriate size on the parts from which the shielding has been stripped, to attach them to the plate 1.

The shielding must be clamped tightly enough to the metal plate to ensure correct contact.

6Shielded cable for motor connection with shielding connected to ground at both ends.

The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.

For 0.18 to 1.5 kW drives, if the switching frequency is higher than 12 kHz, use cables with low linear capacitance: max. 130 pF (picoFarads) per metre.

7Shielded cable for connecting the control/signalling wiring.

For applications requiring several conductors, use cables with a small cross-section (0.5 mm2).

The shielding must be connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.

8Shielded cable for connecting braking resistor (if fitted).

The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes.

Note:

•If using an additional input filter, it should be mounted under the drive and connected directly to the line supply via an unshielded cable. Link 3 on the drive is then via the filter output cable.

•The HF equipotential ground connection between the drive, motor and cable shielding does not remove the need to connect the PE protective conductors (green-yellow) to the appropriate terminals on each unit.

Warnings

B

When the drive is powered up, the power components and some of the control components are connected to the line supply. It is extremely dangerous to touch them. The drive cover must be kept closed.

In general, the drive power supply must be disconnected before any operation on either the electrical or mechanical parts of the installation or machine.

After the ATV has been switched off and the display has disappeared completely, wait for 10 minutes before working on the equipment. This is the time required for the capacitors to discharge.

The motor can be stopped during operation by inhibiting start commands or the speed reference while the drive remains powered up. If personnel safety requires prevention of sudden restarts, this electronic locking system is not sufficient: fit a cut-off on the power circuit.

The drive is fitted with safety devices which, in the event of a fault, can shut down the drive and consequently the motor. The motor itself may be stopped by a mechanical blockage. Finally, voltage variations, especially line supply failures, can also cause shutdowns.

If the cause of the shutdown disappears, there is a risk of restarting which may endanger certain machines or installations, especially those which must conform to safety regulations.

In this case the user must take precautions against the possibility of restarts, in particular by using a low speed detector to cut off power to the drive if the motor performs an unprogrammed shutdown.

The drive must be installed and set up in accordance with both international and national standards. Bringing the device into conformity is the responsibility of the systems integrator who must observe the EMC directive among others within the European Union.

The specifications contained in this document must be applied in order to comply with the essential requirements of the EMC directive.

The ATV 31 must be considered as a component: it is neither a machine nor a device ready for use in accordance with European directives (machinery directive and electromagnetic compatibility directive). It is the responsibility of the end user to ensure that the machine meets these standards.

The drive must not be used as a safety device for machines posing a potential risk of material damage or personal injury (lifting equipment, for example). In such applications, overspeed checks and checks to ensure that the trajectory remains under constant control must be made by separate devices which are independent of the drive.

The products and equipment described in this document may be changed or modified at any time, either from a technical point of view or in the way they are operated. Their description can in no way be considered contractual.

Steps for setting up the starter

1 - Delivery of the drive

•Check that the drive reference printed on the label is the same as that on the delivery note corresponding to the purchase order.

•Remove the ATV 31 from its packaging and check that it has not been damaged in transit.

2 - Check that the line voltage is compatible with the supply voltage range of the drive

(see the ATV 31Installation Manual).

- The drive may be damaged if the line voltage is not compatible.

3 - Fit the drive

4 - Connect the following to the drive:

•The line supply, ensuring that it is:

-compatible with the voltage range of the drive

-switched off

•The motor, ensuring that its coupling corresponds to the line voltage

•The control via the logic inputs

•The speed reference via the logic or analog inputs

B

5 - Switch on the drive, but do not give a run command 6 - Configure the following:

The nominal frequency (bFr) of the motor, if it is different from 50 Hz.

7 - Configure the following in the drCmenu:

The motor parameters, only if the factory configuration of the drive is not suitable.

8 - Configure the following in the I-O-, CtLand FUnmenus:

The application functions (only if the factory configuration of the drive is not suitable), for example the control mode: 3-wire, or 2-wire transition detection, or 2-wire level detection, or 2-wire level detection with forward direction priority, or local control for ATV31pppA.

The user must ensure that the programmed functions are compatible with the wiring diagram used.

9 - Set the following in the SEtmenu:

-The ACC (Acceleration) and dEC (Deceleration) parameters

-The LSP (Low speed when the reference is zero) and HSP (High speed when the reference is maximum) parameters

-The ItH parameter (Motor thermal protection)

10 - Start the drive

Practical recommendations

•Preparations can be made for programming the drive by filling in the configuration and settings tables (see page 76), in particular when the factory configuration has to be changed.

•It is always possible to return to the factory settings using the FCS parameter in the drC-, I-O-, CtLand FUnmenus (return to the configuration selected by the CFG parameter).

The assignment of CFG results directly in a return to the selected configuration.

•For simple applications where the factory settings are suitable, the ATV31 is configured so as to be equally robust as the ATV28 factory settings.

•To achieve optimized drive performance in terms of accuracy and response time, it is essential to:

-Enter the values given on the motor rating plate in the Motor control menu drC- (page 23).

-Perform an auto-tune operation with the motor cold and connected, using parameter tUn in the drCmenu (page 24).

(Auto-tuning measures the stator resistance of the motor in order to optimize the control algorithms).

- Adjust parameters FLG and StA in the Settings menu SEt- (page 20).

•To locate the description of a function quickly, use the index of functions on page 81.

•Before configuring a function, read the "Function compatibility" section on pages 14 and 15.

Setup - Preliminary recommendations

Prior to switching on and configuring the drive

- Check that the line voltage is compatible with the supply voltage range of the drive (see pages 3 and 4 of the ATV 31 Installation Manual). The drive may be damaged if the line voltage is not compatible.

- Ensure the logic inputs are switched off (state 0) to prevent accidental starting. Otherwise, an input assigned to the run command may cause the motor to start immediately on exiting the configuration menus.

With power switching via line contactor

- Avoid operating the contactor frequently (premature ageing of the filter capacitors). Use inputs LI1 to LI6 to control the drive. - These instructions are vital for cycles < 60 s, otherwise the load resistor may be damaged.

B User adjustment and extension of functions

If necessary, the display and buttons can be used to modify the settings and to extend the functions described in the following pages. It is very easy to return to the factory settings using the FCS parameter in the drC-, I-O-, CtLand FUnmenus (set InI to activate the function, see page 26, 30, 41 or 65).

There are three types of parameter:

-Display: Values displayed by the drive

-Setting: Can be changed during operation or when stopped

-Configuration: Can only be modified when stopped and no braking is taking place. Can be displayed during operation.

- Check that changes to the current operating settings do not present any danger. Changes should preferably be made with the drive stopped.

Start up

Important: In factory settings mode on power-up, or in a manual fault reset or after a stop command, the motor can only be powered once the "forward", "reverse" and "DC injection stop" commands have been reset. If they have not been reset, the drive will display "nSt" but will not start. If the automatic restart function is configured (parameter Atr in the FLtmenu, see page 66), these commands are taken into account without a reset being necessary.

Test on a low power motor or without a motor

•In factory settings mode, "motor phase loss" detection is active (OPL = YES). To check the drive in a test or maintenance environment without having to switch to a motor with the same rating as the drive (particularly useful in the case of high power drives), deactivate "motor phase loss" detection (OPL = NO).

•Configure the voltage/frequency ratio: UFt = L (drCmenu on page 24)

• Motor thermal protection will not be provided by the drive if the motor current is less than 0.2 times the nominal drive current.

Using motors in parallel

• Configure the voltage/frequency ratio: UFt = L (drCmenu on page 24)

• Motor thermal protection is no longer provided by the drive. Provide an alternative means of thermal protection on every motor.

Remote terminal option

This module is a local control unit which can be mounted on the door of the wall-mounted or floor-standing enclosure. It has a cable with connectors, which is connected to the drive serial link (see the manual supplied with the terminal). It has the same display and the same programming buttons as the ATV 31 with the addition of a switch to lock access to the menus and three buttons for controlling the drive:

•FWD/REV: reversal of the direction of rotation

•RUN: motor run command

•STOP/RESET: Motor stop command or fault reset

Pressing the button a first time stops the motor, and if DC injection standstill braking is configured, pressing it a second time stops this braking.

• The access locking switch on the remote terminal also prevents the drive settings being accessed via the keypad.

• When the remote terminal is disconnected, if the drive has been locked, the keypad will remain locked.

• In order for the remote terminal to be active, the tbr parameter in the COMmenu must remain in factory settings mode: 19.2 (see page 79).

Saving and loading configurations

Up to four complete configurations for ATV 31 drives can be stored on the remote terminal. These configurations can be saved, transported and transferred from one drive to another of the same rating. 4 different operations for the same device can also be stored on the terminal. See the SCS and FCS parameters in the drC-, I-O-, CtLand FUnmenus.
