Speed controller adaptation

Fundamentals
With the speed controller adaptation, any speed controller oscillation can be suppressed.
The speed-dependent Kp_n/Tn_n adaptation is activated in the factory setting. The required
values are automatically calculated when commissioning and for the rotating measurement.
If, in spite of this, speed oscillations do occur, then in addition the Kp_n component can be
optimized using the free Kp_n adaptation. The free Kp_n adaptation is activated by
connecting a signal source at p1455. The factor calculated from this is multiplied by the Kp_n
value of the speed-dependent adaptation. The range of action of the free Kp_n adaptation is
set using parameters p1456 to p1459
In addition, using p1400.6 = 1, the Tn_n component of the speed-dependent adaptation can
be optimized. The Tn_n value of the speed-dependent adaptation is divided by the factor of
the free adaptation.
