Motor control (MCTRL)
V/f characteristic control (VFCplus)
5.4.3
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
min
boost
(
C00016
).

Freely defining the characteristic
From version 04.00.00
, the V/f characteristic can also be defined freely if the linear and
quadratic characteristics are not suitable.

Adapting drive behaviour
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 (V
encoder) is selected.
