Controlling of the motor according to the various control procedures is executed via the control unit. Apart from the control unit, further functions are available which can be adjusted by parameterization to the corresponding application. In the case of SINAMICS G120, several control units are available in various designs.
The specific control unit (CU230P-2) is ideal for the use with drives with integrated technology functions for pump, fan and compressor applications. The I/O interface, the fieldbus interfaces and the additional software functions optimally support these applications.
