Siemens SINAMICS G120X - Saturation Limit for Flux Setpoint; Max Fluxsaturation; Speed Control Configuration; N_Ctrl Config; U;F Mode Resonance Damping Maximum Frequency; Uf Res_Damp F_Max

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: See also: p1338, p1339
Note
For p1349 = 0, the changeover limit is automatically set to 95 % of the rated motor frequency - however, to a max. of
45 Hz.
p1382[0...n] Saturation limit for flux setpoint / Max FluxSaturation
Access level: 4 Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
100 [%]
Max:
130 [%]
Factory setting:
100 [%]
Description: Maximum flux setpoint (saturation limit) for calculating the EMF in the range of the impressed starting current.

00 Automatic Kp/Tn adaptation active Yes No 6040
05 Kp/Tn adaptation active Yes No 6040
15 Sensorless vector control speed precontrol Yes No 6030
16 I component for limiting Enable Hold 6030
18 Reserved - - -
19 Anti-windup for integral component Yes No 6030
20 Acceleration model ON OFF 6031
21 Free Tn reduction active Yes No 6030
22 Reserved - - -
25 Acceleration torque instantaneous in the I/f mode Yes No -
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).
