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 (p1247 or p1243).
Description: Sets the integral time for the DC-link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective integral time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Note: An integral time is normally not required for single axis drives. For multi-axis drives on the other hand, it may be
possible to compensate for interference from other axes using the integral time (integral component) .
p1251 = 0: The integral component is de-activated.
Description: Sets the rate time constant for the DC-link voltage controller (Vdc_min controller, Vdc_max controller).
Dependency: The effective rate time is obtained taking into account p1243 (Vdc_max controller dynamic factor).
Description: Activates/de-activates the automatic sensing of the switch-in level for the Vdc_max controller.
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: p1256 = 1
Notice: If a time threshold has been parameterized, the Vdc_max controller should also be activated (p1240 = 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.
