6.33.8 Control mode for low current
: Low current detection hysteresis width
: Low current trip selection
: Low current detection current
: Low current detection time
• Function
If the current is lower than level and passes for a time longer than , the inverter trips.
Trip information is displayed as “.”
=: No tripping (Failure signal FL deactivated).
A low current alarm can be put out by setting the output terminal function selection parameter.
=: The inverter will trip (the failure signal FL will be activated) if a current below the current set with
flows for the period of time specified with .
