5.14.8 Optimising pull-out slip limitation
The following object serves to adapt the pull-out slip function or the maximally permissible motor
current in the field weakening range.
• If the motor is to be stalled in the field weakening range, the override point can be offset by
reducing the value so that a motor stalling can be prevented.
• If the motor cannot provide enough torque in the field weakening range, the value has to be
increased.
0x2B0C | 0x330C - VFC: Override point of field weakening

0x2B0B | 0x330B - VFC: Setpoint frequency
Subindex 4: VFC: Oscillation damping - final ramp frequency
Ramp end frequency from which the gain factor is to have reached its rated value.
• By setting a ramp end frequency, a possible negative impact of the oscillation damping on the concentricity
factor in the lower speed range can be reduced.
• The ramp end frequency refers to the rated motor frequency in percent.
