Description: Displays the switch-in level for the Vdc_min controller (kinetic buffering).
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, then this can be realized using the dynamic factor. In this case p1290,
p1291, p1292 are weighted with the dynamic factor p1287.
If several modules are connected to the DC link, then the dynamic factor must be increased corresponding to the
ratio of the additional capacitances to the capacitance of the module involved.
Note: The pre-setting of the dynamic factor is based on the power units connected at DRIVE-CLiQ. It is assumed that the
power unit, connected via DRIVE-CLiQ is also electrically connected to the DC link. If this is not the case, then the
dynamic factor must be optimized manually.
Description: Sets the lower speed threshold for the Vdc_max controller. When this speed threshold is fallen below, the Vdc_max
control is switched-out and the speed is controlled using the ramp-function generator.
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 preset to a value that is optimally
adapted to the capacitance of the individual Motor Module. The capacitances of the other power units, which are
connected to the DC link, can be taken into account using the dynamic factor (p1287 or p1283).
