2.2 List of parameters
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.
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 to DRIVE-CLiQ. It is assumed that the
power units connected via DRIVE-CLiQ are also electrically connected to the DC link. If this is not the case, then the
dynamic factor must be optimized manually.
Description: Sets the feedback factor for the ramp-function generator.
Its ramp times are decelerated relative to the output signal of the Vdc_max controller.
Note: For values p1288 = 0.0 to 0.5, the controller dynamics are automatically adapted internally.
Description: Sets the lower speed threshold for the Vdc_max controller.
When this speed threshold is undershot, 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 pre-set 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).
