Overview
The SINAMICS G120 frequency inverter is designed to provide
precise and cost-effective speed/torque control of three-phase
motors.
With different device versions (frame sizes FSA to FSGX) in a
power range from 0.37 kW to 250 kW (0.5 hp to 400 hp), it is
suitable for a wide variety of drive solutions.
Example: SINAMICS G120, frame sizes FSA, FSB and FSC;
each with Power Module, CU240E-2 F Control Unit and
Basic Operator Panel BOP-2
Example: SINAMICS G120, frame sizes FSD, FSE and FSF;

Operator-friendly design
SINAMICS G120 is a modular inverter 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 (0.5 hp to 400 hp). It features state-of-the-art
IGBT technology with pulse-width-modulated motor voltage and
selectable pulse frequency. Comprehensive protection func-
tions provide a high degree of protection for the Power Module
and the motor.
The Control Units can be combined with the following
Power Modules:
