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 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).
Description: Activates/deactivates the automatic sensing of the switch-in level for the Vdc_max controller. When the sensing
function is deactivated, the activation threshold r1282 for the Vdc_max controller is determined from the parameter-
ized connection voltage p0210.
Value: 0: Automatic detection inhibited
1: Automatic detection enabled
Description: Sets the time threshold for the Vdc_min controller (kinetic buffering). If this value is exceeded a fault is output; the
required response can be parameterized.
Prerequisite: p1296 = 1.
Notice: If a time threshold has been parameterized, the Vdc_max controller should also be activated (p1280 = 3) so that the
drive does not shut down with overvoltage when Vdc_min control is exited (due to the time violation) and in the
event of fault response OFF3. It is also possible to increase the OFF3 ramp-down time p1135.
