Parameters ID720 to ID725 determine the maximum number of automatic restarts
during the trial time set by parameter ID718. The time count starts from the first
autorestart. If the number of faults occurring during the trial time exceeds the values of
parameters ID720 to ID725 the fault state becomes active. Otherwise the fault is cleared
after the trial time has elapsed and the next fault start the trial time count again.
If a single fault remains during the trial time, a fault state is true.
719 Automatic restart: Start function
(2.8.3)
The Start function for Automatic restart is selected with this parameter. The parameter
defines the start mode:
0 = Start with ramp
1 = Flying start
2 = Start according to ID505
720 Automatic restart: Number of tries after undervoltage fault trip
(2.8.4)
This parameter determines how many automatic restarts can be made during the trial
time set by parameter ID718 after and 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
(2.8.5)
This parameter determines how many automatic restarts can be made during the trial
time set by parameter 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
(2.8.6)
(NOTE! IGBT temp fault also included)
This parameter determines how many automatics restarts can be made during the trial
time set by ID718.
0 = No automatic restart after overcurrent fault trip
>0 = Number of automatic restarts after overcurrent trip, saturation trip
and IGBT temperature faults.
723 Automatic restart: Number of tries after reference trip
(2.8.7)
This parameter determines how many automatics 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 analogue current signal
(4…20mA) has returned to the normal level (>
4mA)
