Overview of the SINAMICS G120 family of inverters
Thanks to their modular design, SINAMICS G120 inverters can be used in a wide range of
applications with respect to functionality and power.
Each SINAMICS G120 inverter comprises a Control Unit and a Power Module. The power
range extends from 0.37 kW to 250 kW.
The Basic Operator Panel (BOP) and the STARTER commissioning tool are available for
commissioning.
A range of additional, application-specific components are also available (e.g. filters,
reactors, braking resistors).
2.1 Modularity of the converter system
Main components of the inverter
Each SINAMICS G120 inverter comprises a Control
Unit and Power Module. In the SINAMICS G120 range,
the Control Units can be combined with any Power
Module.
The Control Unit controls and monitors the Power
Module and the connected motor in various control
modes (which can be selected as required). It
supports communication with local or central control
as well as with monitoring devices.
The Power Modules are available for motors with a
power range of between 0.37 kW and 250 kW. IGBT
technology and pulse-width modulation are used to
ensure reliable and flexible motor operation.
