2.2 List of parameters
Description: Activates/deactivates 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
Dependency: Refer to: F07406
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.
Description: Sets the response for the Vdc_min controller (kinetic buffering).
Value: 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 .
Kinetic buffering is not started below the speed threshold.
Note: Exiting the Vdc_min control before reaching motor standstill prevents the regenerative braking current from
increasing significantly at low speeds, and after a pulse inhibit, means that the motor coasts down.
However, the maximum braking torque can be set via the appropriate torque limiting.
