Speed controller adaptation

Function description
With the speed controller adaptation, vibrations that can occur in the speed controller are
suppressed.
Speed-dependent K
automatically calculated when commissioning and for the rotating measurement. If, in spite of
the automatic calculation, speed oscillations do occur, then in addition the K
be tuned using the free K
signal source at p1455. The factor calculated from this is multiplied by the K
speed-dependent adaptation. The range of action of the free K
parameters p1456 to p1459.
In addition using p1400.6 = 1, the T
tuned. The T
adaptation.
The K
reduction of the speed controller is deactivated.
