6.29.7 Control mode for small current
f609 : Small current detection hysteresis
f610 : Small current trip/alarm selection
f611 : Small current detection current
f612 : Small current detection time
 Function
f610=0: No tripping. (Failure signal FL not activated)
f610=1: The inverter will trip if a current below the current set with f611 flows for the period of time

* When setting f610 to 1 (Trip), trip after low current is detected for the period of time set with f612.
After tripping, the low current signal remains ON.
If the output current falls below the value set at f611 and doesn't return above f611+f609
for a time that exceeds the value set at f612, tripping or output alarm will be activated.
uc is displayed in the event of a trip.
A small current alarm can be put out from the output terminal.
