p1285[0...n]
Vdc_min controller switch-in level (kinetic buffering) (U/f) / Vdc_min on_level
Access level: 3
Can be changed: T, U
Unit group: -
Min:
65 [%]
Description:
Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
r1286[V] = p1285[%] * sqrt(2) * p0210
WARNING
An excessively high value may adversely affect normal drive operation.
r1286
Vdc_min controller switch-in level (kinetic buffering) (U/f) / Vdc_min on_level
Access level: 3
Can be changed: -
Unit group: -
Min:
- [V]
Description:
Displays the switch-in level for the Vdc_min controller (kinetic buffering).
Note
The Vdc_min controller is not switched back off until the DC link voltage rises above the threshold 1.05 * r1286 and the
controller output is zero.
p1287[0...n]
Vdc_min controller dynamic factor (kinetic buffering) (U/f) / Vdc_min dyn_factor
Access level: 3
Can be changed: T, U
Unit group: -
Min:
1 [%]
Description:
Sets the dynamic factor for the Vdc_min controller (kinetic buffering).
100% means that p1290, p1291, and p1292 (gain, integral time, and rate time) are used corresponding to their basic
settings and based on a theoretical controller optimization.
If subsequent optimization is required, this can be carried out using the dynamic factor. In this case, p1290, p1291, and
p1292 are weighted with the dynamic factor p1287.
p1290[0...n]
Vdc controller proportional gain (U/f) / Vdc_ctrl Kp
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0.00
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.
