Thealarm signal persists for the FU1-55 even if the currenthas become the level below the FU1-54.Multi-function output terminal (AXA-AXC) is used as thealarm signal output. To output the alarm signal, set I/O44 [Multifunction Auxiliary Contact Output] to ‘OL’.☞ Note: Inverter is not tripped by this function.☞ Note: The set value is the percentage of FU2-33 [RatedMotor Current].FU1-56: Overload Trip SelectionFU1-57: Overload Trip LevelFU1-58: Overload Trip Delay TimeFU1► OLT select56 --- Yes ---56Factory Default: Yes 1FU1► OLT level57 180 %Inverter cuts off its output and displays fault messagewhen the output current persists over the FU1-57[Overload Trip Level] for the time of FU1-58 [OverloadTrip Time].
