The SINAMICS G120 range
The SINAMICS G120 inverter has been designed for the accurate and efficient control of the
speed and torque for three-phase motors. The SINAMICS G120 system comprises two basic
modules, the Control Unit (CU) and the Power Module (PM).
The Control Units are divided into the following:
● Standard CUs (CUs without fail-safe functions)
– CU240S
– CU240S DP like CU 240S plus PROFIBUS DP interface
● CUs with fail-safe functions
– CU240S DP-F like CU240S DP plus integrated fail-safe functions
The Power Modules are divided as follows:
● PM240 Power module with dc braking functions, supply voltage 3 AC 400 V
● PM250 Power module with regenerative mode supply voltage
– 3 AC 400 V
– 3 AC 690 V
Control Units and Power modules are allowed to be combined in any possible configuration.
See the respective manual for specific functions and features.
