14.1 A
UTOMATIC RESET
Activate the Automatic reset after fault with this parameter.
NOTE: Automatic reset is allowed for certain faults only.
Fault: 1 . Under voltage
2 . Over voltage
3 . Over current
4 . Motor temperature
5 . Under load
14.3 T
RIAL TIME
The Automatic restart function restarts the frequency converter when the
faults have disappeared and the waiting time has elapsed.
The time count starts from the first autoreset. If the number of faults occur-
ring during the trial time exceeds three, the fault state becomes active. Oth-
erwise the fault is cleared after the trial time has elapsed and the next fault
starts the trial time count again. See Figure 9.16.
If a single fault remains during the trial time, a fault state is true.
