Description: Sets the response for the Vdc_min controller (kinetic buffering).
Values: 0: Buffer Vdc until undervoltage, n<p1257 -> F07405
1:
Buff. Vdc until undervolt., n<p1257 -> F07405, t>p1255 -> F07406
Dependency: Refer to: F07405, F07406
Description: Sets the speed threshold for the Vdc-min controller (kinetic buffering). If this value is exceeded a fault is output; the
required response can be parameterized .
Description: Displays the actual output of the Vdc controller (DC link voltage controller)
Note: The regenerative power limit p1531 is used for vector control to pre-control the Vdc_max controller. The lower the
power limit is set, the lower the correction signals of the controller when the voltage limit is reached.
Description: Selecting the bypass functionality.
Values: 0: Bypass function de-activated
1: Bypass with synchronization and overlap
2: Bypass with synchronization without overlap
3: Bypass without synchronization
Dependency: The bypass functionality is enabled together with the function module "technology controller (r0108.16).
For p1260 = 2 (bypass with synchronization without overlap) and p1260 = 3 (bypass without synchronization), then
the "flying restart" function must be activated (p1200).
