■Output terminal function(open collector, relay outputs) settings and detection levels

Technical terms

Alarm:・・・・・・・・・・・・・・ Alarm output beyond a certain setting value

Pre-alarm: ・・・・・・・・・・ Alarm output of the state where the inverter may carry out a trip by continuation

Serious failure: ・・・・・・ Output signal in a serious failure of the protection function of the inverter. (Arm over-current(, , ), Load side over-current(), Short- circuiting(, ), Phase failure(, ), etc.)

Light failure:・・・・・・・・・ Output signal in a slight failure of the protection function of the inverter. (Over-load(, ), Over-voltage(, , ), Over-current(, , , , , ), etc.)

Emergency stop: ・・・・ Output signal when the inverter comes into emergency stop. Stopping manner is set with (emergency stop).
