Description of Parameters
720 Automatic restart: Number of
tries after undervoltage fault
trip
234567 (P1.8.4)
This parameter determines how many automatic restarts can be made during the trial
time set by ID718 after an undervoltage trip.
0 No automatic restart
>0 Number of automatic restarts after undervoltage fault. The fault is reset
and the drive is started automatically after the DC-link voltage has
returned to the normal level.
721 Automatic restart: Number of
tries after overvoltage trip
234567 (P1.8.5)
This parameter determines how many automatic restarts can be made during the trial
time set by ID718 after an overvoltage trip.
0 No automatic restart after overvoltage fault trip
>0 Number of automatic restarts after overvoltage fault trip. The fault is
reset and the drive is started automatically after the DC-link voltage has
returned to the normal level.
722 Automatic restart: Number of
tries after overcurrent trip
234567 (P1.8.6)
This parameter determines how many automatic restarts can be made during the trial
time set by ID718.
Note: An IGBT temperature fault also included as part of this fault.
0 No automatic restart after overcurrent fault trip
>0 Number of automatic restarts after an overcurrent trip, saturation trip or
IGBT temperature fault.
723 Automatic restart: Number of
tries after reference trip
234567 (P1.8.7)
This parameter determines how many automatic restarts can be made during the trial
time set by ID718.
0 No automatic restart after reference fault trip
>0 Number of automatic restarts after the analog current signal (4 – 20 mA)
has returned to the normal level (≥ 4 mA)
725 Automatic restart: Number of
tries after external fault trip
234567 (P1.8.9)
This parameter determines how many automatic restarts can be made during the trial
time set by ID718.
0 No automatic restart after External fault trip
>0 Number of automatic restarts after External fault trip
