Optimising the control mode

The V/f characteristic control (VFCplus) is generally ready for operation. It can be adapted
subsequently by adapting the characteristic and/or the drive behaviour.
Adapting characteristic
For the linear and quadratic characteristic, it is also possible to match its curve to different
load profiles or motors by adapting the V/f base frequency (C00015) and the V
(C00016).

quadratic characteristics are not suitable.

 Limitation of the maximum current by a current limitation controller (e.g. to prevent
the motor from stalling or to limit to the maximally permissible motor
current).
 Adaptation of the field frequency by a load-dependent slip compensation (improved
speed accuracy for systems without feedback)
 Adaptation of the controller parameters of the slip regulator if V/f control (VFCplus +
encoder) is selected.
