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 auto reset. If the number of faults occur-
ring during the trial time exceeds trail number (the value of P14.4), 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 9.22.
If a single fault remains during the trial time, a fault state is true.
