6.11.2 Speed Control
The integrated speed controller is used at cS.0 = „2“ for the slip compensation. Slip
compensation compensates the speed changes caused through load changes by
increasing/decreasing the output frequency (ru.3). With that a higher speed stability is
achieved.
If one determines during operation that the drive constantly overcompensates, it can
be balanced by a slight increase of the rated speed.

6.11.2 Drehzahlregler
Parameter uF.16 defines the basic controller structure.
Dec. Meaning
0 Torque compensation off
1 Torque compensation acts motoric and generatoric
2 Torque compensation works only in the motoric operation; resulting in a smoother
run in the generatoric operation.
3 Torque compensation in motoric operation; overcompensation in the generatoric
operation; resulting in a higher maximum torque and increased current in the
generatoric operation compared to 1 and 2; because of the higher motor-own
losses a braking resistor is only necessary at higher energy recovery compared
to 0, 1 and 2.
