Introduction - Siemens SINAMICS G120 Hardware Installation Manual

Introduction

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
● CU with 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
● 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.
