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 optional removable control unit (BDE) or using a PC and an PC software package. 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 22 kVA to 330 kVA. In conjunction with standard asynchronous motors the drive capacities provided are therefore as follows: - At unit rated current 18.5 kW to 200 kW, 400 V 21 kW to 230 kW, 480 V - At unit basic load current 15 kW to 160 kW, 400 V 17 kW to 184 kW, 480 V Note: This operating manual applies to the following units: ALSPA MD2000 22/27-400 . 225/275-400 Software version: V3.0 Ref. No.: 029.152 730 Important! ALSPA MD2000 units are designed as standard for operating on earthed networks. 1 Brief description 2 ALSPA MD2000 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. ALSPA MD2000 units 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 ALSPA MD2000 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.
