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:
● CU without fail-safe functions
– CU230P-2 HVAC for pump and fan applications with Modbus RTU interface
– CU230P-2 CAN for pump and fan applications with CANopen interface
– CU230P-2 DP for pump and fan applications with PROFIBUS DP interface
– CU240E economic version of the CU240 Control Units (e.g. less terminals, no
encoder interface)
– CU240S standard version of the CU240 Control Units
– CU240S DP like CU240S plus PROFIBUS DP interface (PROFIdrive Profile V4.1)
– CU240S PN like CU240S plus PROFINET interface (PROFIdrive Profile V4.1)
● CU with fail-safe functions
– CU240S DP-F like CU240S DP plus integrated fail-safe functions
– CU240S PN-F like CU240S PN plus integrated fail-safe functions
The Power Modules differ concerning the supply voltage and the way of realizing the motor
braking function:
● PM240 Power Module with resistor braking and dc braking functions, supply voltage
3 AC 400 V
● PM250 Power Module with regenerative braking function, supply voltage 3 AC 400 V
● PM260 Power Module with regenerative braking function, supply voltage 3 AC 690 V
Control Units and Power Modules are allowed to be combined in any possible configuration.
Exceptions:
The CU230P-2 with firmware V4.2 can not be combined with PM240 FSGX or PM260.
These combinations will be allowed with firmware V4.3.
See the respective manual for specific functions and features.
