Motor Modules are available for the following voltages and power ratings:
Line voltage
380 ... 480 V 3 AC
500 ... 690 V AC, 3-phase
The available shaft output can be increased by connecting up to 4 Motor Modules in parallel.
These modules are operated on one Control Unit and feed one motor.
Note
Note that the Motor Modules connected in parallel are operated on a common CU320
Control Unit.
