Dependency: See also: p1340
Note
The controller settings are also used in the current controller of the DC braking (refer to p1232).
p1346[0...n] I_max voltage controller integral time / I_max_U_ctrl Tn
Access level: 3 Calculated: CALC_MOD_CON Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6300, 7017
Min:
0.000 [s]
Max:
50.000 [s]
Factory setting:
0.030 [s]
Description: Sets the integral time for the I_max voltage controller.
Dependency: See also: p1340
Note
The controller settings are also used in the current controller of the DC braking (refer to p1232).
For p1346 = 0, the following applies:
The integral time of the I_max voltage controller is deactivated.
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
Note
For p1349 = 0, the changeover limit is automatically set to 95 % of the rated motor frequency - however, to a max. of
45 Hz.
