28 Operation principle and hardware description
Operation principle
The ACS580-01 is a drive for controlling asynchronous AC induction motors and
permanent magnet synchronous motors.
The figure below shows the simplified main circuit diagram of the drive.
1
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
Built-in brake chopper (R-, R+) in frames R0…R3. Conducts the surplus energy from
the intermediate DC 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. The
user obtains and installs the brake resistor when needed.
5
DC connection (UDC+, UDC-), for an external brake chopper in frames R4…R9.
