Modularity of the converter system
Main components of the frequency inverter
Each SINAMICS G120 frequency 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 different
control modes (which can be selected as required).
It supports communication with a local or central
controller as well as with monitoring devices.
•
The Power Modules are available for motors with an
output range of between 0.37 kW and 132 kW. IGBT
technology and pulse-width modulation are used to
ensure reliable and flexible motor operation.
