1 Safety information

1.1 Warnings, Cautions and Notes

1.2 Electrical safety - general warning

The voltages used in the drive can cause severe electrical shock and/or burns, and could be lethal.

Extreme care is necessary at all times when working with or adjacent to the drive. Specific warnings

are given at the relevant places in this guide.

1.3 System design and safety of personnel

The drive is intended as a component for professional incorporation into complete equipment or a

system. If installed incorrectly, the drive may present a safety hazard.

The drive uses high voltages and currents, carries a high level of stored electrical energy, and is used

to control equipment which can cause injury.

Close attention is required to the electrical installation and the system design to avoid hazards either

in normal operation or in the event of equipment malfunction. System design, installation,

commissioning/start-up and maintenance must be carried out by personnel who have the necessary

training and experience. They must read this safety information and this User Guide carefully.

The STOP and SAFE TORQUE OFF functions of the drive do not isolate dangerous voltages from

the output of the drive or from any external option unit. The supply must be disconnected by an

approved electrical isolation device before gaining access to the electrical connections.

With the sole exception of the SAFE TORQUE OFF function, none of the drive functions must

be used to ensure safety of personnel, i.e. they must not be used for safety-related functions.

Careful consideration must be given to the functions of the drive which might result in a hazard,

either through their intended behavior or through incorrect operation due to a fault. In any application

where a malfunction of the drive or its control system could lead to or allow damage, loss or injury, a

risk analysis must be carried out, and where necessary, further measures taken to reduce the risk -

for example, an over-speed protection device in case of failure of the speed control, or a fail-safe

mechanical brake in case of loss of motor braking.

The SAFE TORQUE OFF function may be used in a safety-related application. The system designer

is responsible for ensuring that the complete system is safe and designed correctly according to the

relevant safety standards.

1.4 Environmental limits

Instructions in this guide regarding transport, storage, installation and use of the drive must be

complied with, including the specified environmental limits. Drives must not be subjected to

excessive physical force.

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.

1.5 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 the Drive User Guide.

1.7 Compliance with regulations

The installer is responsible for complying with all relevant regulations, such as national wiring

regulations, accident prevention regulations and electromagnetic compatibility (EMC) regulations.

Particular attention must be given to the cross-sectional areas of conductors, the selection of fuses

or other protection, and protective ground (earth) connections.

This guide contains instruction for achieving compliance with specific EMC standards.

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

following directives:

2006/42/EC: Safety of machinery.

2004/108/EC: Electromagnetic Compatibility.

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.

2.1 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

With position feedback sensor

Without position feedback sensor (Sensorless)

3. RFC - S

With position feedback sensor

Without position feedback sensor (Sensorless)

2.1.1 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.

Introduction

Control connections Getting started Basic parameters

(Menu 0) Running the motor Further information

2.1.2 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.

2.1.3 RFC- S

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.

Without position feedback

For use with permanent magnet brushless motors without a feedback device installed.

Flux control is not required because the motor is self excited by the permanent magnets which form

part of the rotor.

Full torque is available all the way down to zero speed, with salient motors.
