p1255[0...n] Vdc_min controller time threshold / Vdc_min t_thresh
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: REL
Min
0.000 [s]
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.

p1257[0...n] Vdc_min controller speed threshold / Vdc_min n_thresh
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Functions
Not for motor type: REL
Min
0.00 [rpm]
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.
