No speed setpoint smoothing is active.
Smoothing of the speed setpoint as requested by the PLC using IS DB31, ...
DBX20.3
("Speed setpoint smoothing") takes effect because speed setpoint filter 1 is
configured as the low pass.
The integrator of the speed controller is enabled. The speed controller
functions as a PI controller.
Deactivation of the speed-controller integrator as requested by the PLC using
IS DB 31, ... DBX 21.6
("Integrator disable speed controller") is active for the drive module. The
speed controller has therefore switched from a PI to a P controller.
