The SINAMICS DCM is primarily used to control DC motors.
The universal suitability of the SINAMICS DCM as a DC drive also allows it to be used as an adjustable voltage source.
Since the integrated field supply is not required in this case, the SINAMICS DCM can be used with option L10 (without field
power unit).
Several examples of how to use the SINAMICS DCM as a voltage regulator are described below.
Perform commissioning according to Chapter 8.2 of the SINAMICS DCM DC Converter operating instructions.
