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

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.
