p1250[0...n] Vdc controller proportional gain / Vdc_ctrl Kp
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.00
Max:
100.00
Factory setting:
1.00
Description: Sets the proportional gain for the DC link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective proportional gain is obtained taking into account p1243 (Vdc_max controller dynamic factor) and the DC
link capacitance of the power unit.
p1251[0...n] Vdc controller integral time / Vdc_ctrl Tn
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6220
Min:
0 [ms]
Max:
10000 [ms]
Factory setting:
0 [ms]
Description: Sets the integral time for the DC link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective integral time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Note
p1251 = 0: The integral component is deactivated.
p1252[0...n] Vdc controller rate time / Vdc_ctrl t_rate
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 6220
Min:
0 [ms]
Max:
1000 [ms]
Factory setting:
0 [ms]
Description: Sets the rate time constant for the DC link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective rate time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
p1254 Vdc_max controller automatic ON level detection / Vdc_max SenseOnLev
Access level: 3 Calculated: - Data type: Integer16
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
0
Max:
1
Factory setting:
1
Description: Activates/deactivates the automatic sensing of the switch-in level for the Vdc_max controller.
Value: 0: Automatic detection inhibited
1: Automatic detection enabled
p1255[0...n] Vdc_min controller time threshold / Vdc_min t_thresh
CUG120XA_USS
(Vdc_min)
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.000 [s]
Max:
1800.000 [s]
Factory setting:
0.000 [s]
Description: Sets the time threshold for the Vdc_min controller (kinetic buffering).
If this value is exceeded a fault is output; the required response can be parameterized.
