2.2 List of parameters
Notice: If a time threshold has been parameterized, the Vdc_max controller should also be activated (p1280 = 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<p1297 -> F07405
1:
Buff. Vdc until undervolt., n<p1297 -> F07405, t>p1295 -> F07406
Note: Re p1296 = 1:
The quick stop ramp entered in p1135 must not be equal to zero, to prevent overcurrent shutdown if F07406 is
triggered.
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 .
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.
Description: Displays the actual output of the Vdc controller (DC link voltage controller)
Description: Sets the U/f control mode of the drive.
Value: 0: U/f control with linear characteristic
1: U/f control with linear characteristic and FCC
2: U/f control with parabolic characteristic
3: U/f control with parameterizable characteristic
4: U/f control with linear characteristic and ECO
5: U/f control for drives requiring a precise freq. (e.g. textiles)
6: U/f control for drives requiring a precise frequency and FCC
