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 autorestart. If the number of faults occurring
during the trial time exceeds three, the fault state becomes active. Otherwise
the fault is cleared after the trial time has elapsed and the next fault starts the
trial time count again. See Figure 10.15.
If a single fault remains during the trial time, a fault state is true.
