Description: Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
p1286[V] = p1285[%] * sqrt(2) * p0210
Warning: An excessively high value may adversely affect normal drive operation.
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 * p1286 and
the controller output is zero.
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.
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.
