Siemens SINAMICS DCM Operating Instructions Manual page 541

The following diagram shows the step response of the speed controller if the same controller
parameters are set as shown previously, however, with the reference model activated.

Note
See Chapter "Commissioning", Section "Manual optimization" for the procedure to manually
optimize the speed controller.
Use of the speed controller for other applications
If the SINAMICS DCM is not used for the speed control of a motor, but rather for the voltage
control of a capacitor load, it may be advantageous to support the speed controller working
as a voltage controller with a load connection. The "Load connection" function block is
available for this purpose. This function block is shown in function diagram 6851. It provides
an additional current setpoint that is preferably fed in at p50601[3] (see function diagram
6840).
