Operation principle

The ACS310 is a wall or cabinet mountable drive for controlling AC induction motors.
The figure below shows the simplified main circuit diagram of the drive. The rectifier
converts three-phase AC voltage to DC voltage. The capacitor bank of the
intermediate circuit stabilizes the DC voltage. The inverter converts the DC voltage
back to AC voltage for the AC motor.
