The following sources are available for the displayed setpoint:
- setpoint at the ramp-function generator input (r1119).
- speed setpoint 1 (p1155).
- speed setpoint 2 (p1160).
- speed setpoint for the speed pre-control (p1430).
- setpoint from DSC (for DSC active).
- setpoint via PC (for master control active, p3983).
Dependency: Refer to: r1119, p1155, p1160, p1430
Description: Displays the sum of all velocity setpoints that are present.

Description: Displays the actual, smoothed actual speed for speed control.
Description: Sets the smoothing time for the actual speed of the speed controller for sensorless closed-loop speed control.
Note: The smoothing must be increased if there is gear backlash. For longer smoothing times, the integral time of the
speed controller must also be increased (e.g. using p0340 = 4).
