 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
).
Servo control (SC):
• Reduce the jerk limitation with C00274
.
• 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
).
