The chapter briefly describes the operation principle, layout, type designation label and type designation information. 

It also shows a general diagram of power connections and control interfaces .

Operation Principle

The ACS320 is a wall or cabinet mountable drive for controlling 

AC motors .
The 

Figure 1

 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 .
