Description: Sets the dynamic factor for the DC link voltage controller (Vdc_max controller).
100% means that p1250, p1251, and p1252 (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 p1250, p1251,
p1252 are weighted with the dynamic factor p1243.
Description: Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
r1246[V] = p1245[%] * sqrt(2) * p0210
Dependency: Refer to: p0210
Warning: An excessively high value may adversely affect normal drive operation.
Description: Sets the switch-in level for the Vdc-min controller (kinetic buffering).
The value is obtained as follows:
r1246[V] = p1245[%] * sqrt(2) * p0210
Dependency: Refer to: 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 * p1246 and
the controller output is zero.
