2.2 List of parameters
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).
Description: Sets the integral time for the Vdc controller (DC link voltage controller).
Description: Sets the rate time constant for the Vdc controller (DC link voltage controller).
Description: Sets the output limit for the Vdc min controller (DC link undervoltage controller).
