G120

The SINAMICS G120 frequency converter is designed to provide precise and cost-effective speed/torque control of three-phase motors.

 

SINAMICS G120 is a modular converter system that essentially comprises two function units:

  • Control Unit (CU)
  • Power Module (PM)

The Control Unit controls and monitors the Power Module and the connected motor using several different closed-loop control types that can be selected. It supports communication with a local or central controller and monitoring devices.

The Power Module supplies the motor in the power range 0.37 kW to 250 kW. It features state-of-the-art IGBT technology with pulse-width-modulated motor voltage and selectable pulse frequency. Comprehensive protection functions provide a high degree of protection for the Power Module and the motor.

The Control Units can be combined with the following Power Modules, PM240-2 and PM250

The G120 allows for operation with a combination of control units, depending on type of application.

Control units are as follows

CU230P-2

CU240E-2

CU250S-2

CU230P-2 HVAC, CU230P-2 DP, CU230P-2 PN

CU240E-2, CU240E-2 DP, CU240E-2 PN, CU240E-2 F, CU240E-2 DP F, CU240E-2 PN F

CU250S-2, CU250S DP, CU250S-2 CAN
