LED"000"digit: inverter OL act Set protection mode while over load.
0: emergency stop output and alarm While OL protection action is caused by too big output current of inverter,
inverter stops output. Motor freely stop. And inverter alarm fault E.oL2.
1: emergency stop and alarm While OL protection action is caused by too big output current of inverter, inverter stops.
Motor DEC stop. And inverter alarm fault E.oL2.
2: limit current and run While OL protection action is caused by too big output current of inverter, inverter switches to
current limited run. Inverter makes output current be limited within rated current by reduce output frequency actively.
LED "0000" digit: motor OL act
0: emergency stop output and alarm While OL protection action is caused by too big output current of motor, inverter
stops output. Motor freely stop. And inverter alarm fault E.oL1.
1: emergency stop and alarm While OL protection action is caused by too big output current of motor, inverter stops.
Motor DEC stop. And inverter alarm fault E.oL1.
2: limit current and run While OL protection action is caused by too big output current of motor, inverter switches to
current limited run. Inverter makes output current be limited within rated current by reduce output frequency actively.
3: motor OL protection off
Note: If "emergency stop and alarm" is selected while inverter or motor OL, inverter will do like this:
1: After enter emergency stop state; inverter does not accept any orders including fault reset order until
emergency stop state end.
2: In emergency stop process, fault signal is output immediately while multi function output terminal is set as
fault jump alarm 1. Fault signal is output after inverter DEC finished while multi function output terminal is
set as fault jump alarm 2.
3: In emergency stop process, Keyboard LED displays fault information.

0: emergency stop output and alarm While OH protection action is caused by too high temperature of inverter,
inverter stops output. Motor freely stop. And inverter alarm fault E.OH1.
1: emergency stop and alarm While OH protection action is caused by too high temperature of inverter, inverter stops.
Motor DEC stop. And inverter alarm fault E.OH1.
