How to adapt the peak current limitation:
V/f characteristic control (VFCplus):

• Reduce the slip compensation with

C00021

.

V/f control (VFCplus + encoder):

• Reduce the slip limitation to twice the rated motor slip with

C00971

.

• Reduce the V

min

boost in

C00016

.

Sensorless vector control (SLVC):

• Reduce the slip compensation with

C00021

.

• Reduce the limitation of the torque in motor mode via nTorqueMotLimit_a (

C00728/1

)

and the limitation of the torque in generator mode via nTorqueGenLimit_a (

C00728/2

).
