2.2 List of parameters
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
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.
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: Sets the configuration for the bypass function.
Value: 0: Bypass de-activated
1: Bypass with synchronization and overlap
2: Bypass with synchronization without overlap
3: Bypass without synchronization
Note: If the bypass function is selected ((p1260 > 0), then when the power unit restarts after POWER OFF, the state of the
bypass switch is evaluated. This means that after the ramp-up, it is possible to directly change into the standby
mode. This is only possible for p1267 = 1 (bypass using the control signal) and if the control command after the
system has been booted is still available (p1266). This function has a higher priority than the automatic restart
function (p1210).
