p1290[0...n] Vdc controller proportional gain (U/f) / Vdc_ctrl Kp
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: 6320, 6854
Min:
0.00
Max:
100.00
Factory setting:
1.00
Description: Sets the proportional gain for the Vdc controller (DC link voltage controller).
Note
The gain factor is proportional to the capacitance of the DC link.
The parameter is pre-set to a value that is optimally adapted to the capacitance of the power unit.
p1291[0...n] Vdc controller integral time (U/f) / 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: 6320, 6854
Min:
0 [ms]
Max:
10000 [ms]
Factory setting:
40 [ms]
Description: Sets the integral time for the Vdc controller (DC link voltage controller).
p1292[0...n] Vdc controller rate time (U/f) / Vdc_ctrl t_rate
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: 6320, 6854
Min:
0 [ms]
Max:
1000 [ms]
Factory setting:
10 [ms]
Description: Sets the rate time constant for the Vdc controller (DC link voltage controller).
p1294 Vdc_max controller automatic detection ON signal level (U/f) / Vdc_max SenseOnLev
Access level: 3 Calculated: - Data type: Integer16
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: 6320, 6854
Min:
0
Max:
1
Factory setting:
0
Description: Activates/deactivates the automatic sensing of the switch-in level for the Vdc_max controller. When the sensing
function is deactivated, the activation threshold r1282 for the Vdc_max controller is determined from the
parameterized connection voltage p0210.
Value: 0: Automatic detection inhibited
1: Automatic detection enabled
p1295[0...n] Vdc_min controller time threshold (U/f) / Vdc_min t_thresh
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:
10000.000 [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.
