Operation principle and hardware description
What this chapter contains
This chapter describes the operating principle and construction of the drive module
in short.
Product overview
The ACS850-04 is a drive module for controlling asynchronous AC induction motors,
permanent magnet motors and ABB synchronous reluctance motors (SynRM
motors).
The main circuit of the drive module is shown below.
1
AC choke
2
Rectifier. Converts alternating current and voltage to direct current and voltage.
3
DC link. DC circuit between rectifier and inverter
4
Inverter. Converts direct current and voltage to alternating current and voltage.
5
Brake chopper (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 certain maximum limit. The voltage rise is typically caused by deceleration
(braking) of a high inertia motor.
