SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
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 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.
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).
