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.

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:

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.
