p1349[0...n]
U/f mode resonance damping maximum frequency / Uf res_damp f_max
Access level: 3
Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: T, U
Scaling: -
Dynamic index: DDS, p0180
Unit group: -
Unit selection: -
Function diagram: 6310
Min:
0.00 [Hz]
Max:
3000.00 [Hz]
Factory setting:
0.00 [Hz]
Description:
Sets the maximum output frequency for resonance damping for U/f control.
Resonance damping is inactive above this output frequency.
Dependency:

Note
For p1349 = 0, the changeover limit is automatically set to 95 % of the rated motor frequency - however, to a max. of
45 Hz.

Note
For bit 16:
When the bit is set, the integral component of the speed controller is only held if it reaches the torque limit.
For bit 19, 20:
When this bit is set, speed overshoots when accelerating along the torque limit and for load surges are reduced.
For bit 20:
The acceleration model for the speed setpoint is only active if p1496 is not zero.
For bit 25:
When the bit is set, for high dynamic starting in the I/f mode, the acceleration precontrol torque smoothing only has a
short minimum time (4 ms).
