Product overview
ACS580-04 is a drive module for controlling AC induction motors, synchronous
reluctance (SynRM) motors and synchronous permanent magnet motors in open loop
control.
The figure below shows the simplified main circuit diagram of the drive module.

Rectifier. Converts alternating current and voltage to direct current and voltage.2
DC link. DC circuit between rectifier and inverter.3
Inverter. Converts direct current and voltage to alternating current and voltage.4
Brake chopper (option +D150). Conducts the surplus energy from the intermediate circuit of the
drive to the brake resistor when necessary. The chopper operates when the DC link voltage exceeds
a certain maximum limit. The voltage rise is typically caused by deceleration (braking) of a high
inertia motor.
