Output terminal function (open collector, relay outputs) setting and detection levels
For the open connector output terminals (OUT1, OUT2) and the relay output terminals (FLA, FLB and FLC),
functions can be selected from 120 functions (functions 0 to 119). The selectable functions and detection levels are
listed in the table below.
Up to 7 output terminals can be used if add-on cassette options are used in combination with the inverter, while up to
3 output terminals can be used if no cassette option is used.
<Technical terms>
・ Alarm
・ Pre-alarm
・ Serious failure ...... Output signal in a serious failure of the protection function of the inverter.
・ Light failure
・ Emergency stop

...... Alarm output beyond a certain setting value.
...... Alarm output of the state where the inverter may carry out a trip by continuation.
(Arm overcurrent ( oca1 , 2, 3 ), Load side overcurrent ( ocl ), Short-circuiting
( ef1 , ef2 ), Phase failure ( eph0, eph1 ), Abnormal output current detection
( err7 ))
...... Output signal in a slight failure of the protection function of the inverter.
(Overload ( ol1 , 2 ), overvoltage ( op1 , 2 , 3 ), overcurrent during
acceleration/deceleration/fixed speed operation ( oc1 , 1p , 2 , 2p , 3 , 3p ))
...... Output signal when the inverter comes into emergency stop.
Stopping manner is set with f603 (emergency stop).
