Oscillation damping: Gain
-100 ... [20] ... 100 %
Gain of the oscillation signal.
•
With the setting 0, oscillation damping is deactivated.
0x2B0A:002
Oscillation damping: Filter time
1 ... [5] ... 600 ms
Time constant of the PT1 filter.
0x2B0A:003
Oscillation damping: Limitation
0.1 ... [0.2] ... 20.0 Hz
Limitation of the calculated oscillation frequency.
0x2B0A:004
Oscillation damping: Final ramp frequency
0 ... [0] ... 100 %
Ramp end frequency from which the gain factor is expected 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 per-
centage terms.

Optimising the stalling behaviour
The stalling protection function or the maximum permissible motor current in the field weak-
ening range can be adapted.
•
If the motor stalls in the field weakening range, the override point can be shifted by reduc-
ing the set value so that the motor stalling can be prevented.
•
If the motor does not provide enough torque in the field weakening range, the set value
must be increased.
