1 Brief description

BA8230 1

1.1 General 8230 frequency inverter are processor-controlled pulse inverters with a field-orientated

control concept for continuous low-loss speed adjustment of AC motors.

The power stack consists of a diode rectifier in a 3-phase bridge circuit on the mains

side and an IGBT inverter on the motor side.

The basic inverter models are designed for standard applications. Through suitable

options (eg. bus couplers, encoder interface) the units can be integrated into

automation systems and can also fulfil highly dynamic requirements.

Operation of all units is identical throughout the entire type range. Easy familiarisation

and operation as well as maximum flexibility were the prime objectives during

development.

The inverters are operated and parameters adjusted by means of a control unit

(BDE).

Connection to automation systems is possible through conventional bus systems (see

field bus coupler options).

With a mains voltage range from 380 to 480 V build-in units cover the power range

from 144 kVA to 330 kVA.

In conjunction with standard asynchronous motors the drive capacities provided are

therefore as follows:

- At unit rated current

110 kW to 200 kW, 400 V

- At unit 1.5 x rated current

132 kW to 250 kW, 400 V

Note:

This operating manual applies to the following units:

8230 frequency inverter

Software version:

V2.0

Important!

8230 frequency inverter are designed as standard for operating on earthed networks.

1.2 Basic operation The link voltage is generated from the mains supply through the mains rectifier. A 3-

phase choke connected to the mains supply reduces harmonic currents and serves to

decouple the unit from other converters (consumers) on the same supply network.

8230 frequency inverter are connected as standard to an earthed network.

The link voltage is smoothed by high quality electrolytic capacitors. With the motor

converter these provide the magnetising reactive power required by the motor and

decouple the converter on the mains side from the inverter on the motor side.

Through optimised pulse width modulation the motor converter generates from the

link voltage a sinusoidal 3-phase system with variable frequency and voltage.

A power dump (option) in conjunction with a braking resistor allows braking energy to

be used in regenerative operation.

Control and regulation of the 8230 frequency inverter are fully digital. Different control

structures such as, frequency control, speed control with or without encoder and

torque control with or without encoder can be selected, depending on the application

requirements. The field-orientated control concept provides control dynamics directly

comparable to those of a DC drive.

In addition, various inputs and outputs can be connected individually according to the

task involved. Thus the drive system can very easily be customised for the

requirements of the specific application.
