SINAMICS G120 compact variable frequency drive

The SINAMICS G120 is a modular frequency converter that is assembled from a Control Unit and a Power Module. The Control Unit is chosen for the required interface, for example PROFINET, PROFIBUS, EtherNet/IP, USS/Modbus RTU or CANopen, and for safety features such as Safe Torque Off. The Power Module covers input voltages of 200 to 240 V and 380 to 480 V, and its power range is about 0.37 kW to 250 kW depending on the frame size. Vector or U/f control, braking functions, and a commissioning tool in the form of an Intelligent Operator Panel are provided. The compact member of the family, the G120C, combines both parts in one housing. Typical applications are conveyors, pumps, fans, compressors and general machine drives.
