The parameter specifies the maximum useful motor speed and the useful motor velocity in
closed-loop speed controlled operation, and represents the setpoint for P0618.
Note:
The maximum useful motor speed, set via P1401:8, is not exceeded, independent of whether
the setpoint is entered via terminal or PROFIBUS.
