Motor control (MCTRL)
V/f characteristic control - energy-saving (VFCplusEco)
5.5.4
Optimising the control mode
The V/f characteristic control - energy-saving (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 characteristic as part of the V/f characteristic control - energy-saving
(VFCplusEco), it is also possible (like in case of the standard V/f characteristic control) to
match its curve to different load profiles or motors by adapting the V/f base frequency
(
C00015
) and the V
min
boost (
C00016
).

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).

speed accuracy for systems without feedback).

Note!
For an adaptation of the V
min
boost, the V/f characteristic control - energy-
saving (VFCplusEco) must not be set. For this purpose, set the
V/f characteristic
control (VFCplus)
