6.24.7 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
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.
f610=0: No tripping. (Failure signal FL not activated)
A small current alarm can be put out by setting the output terminal function selection parameter.
f610=1: The inverter will trip if a current below the current set with f611 flows for the period of time
specified with
f612. (Failure signal FL activated)

* When setting f610 to 1 (Trip), trip after low current detection time setting of f612. After tripping,
the low current signal remains ON.
