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
Serious failure: ･･････ Output signal in a serious failure of the protection function of the inverter.
Light failure: ････････ Output signal in a slight failure of the protection function of the inverter.
Emergency stop: ････ Output signal when the inverter comes into emergency stop.
