DESCRIPTIONS
GROUP 7. Automatic Restarts
7.2
AUTOMATIC RESTART, TRIAL TIME
The automatic restart function restarts the frequency converter when the
faults have disappeared and waiting time has elapsed.
The time count starts from the first autorestart. If more than three faults occur during trial time, the fault mode is activated. Otherwise, the fault is
cleared after the trial time has elapsed and the next fault starts the trial time
count again. See Figure 10.8.
If one single fault remains during the trial time, fault mode is true.
