, Options of alarm 1 and 2 (Setting range: 000 to 111) (Option)[Description]• These parameters are used to switch ON/OFF the alarmlatch, the error satus alarm, and the de-energized outputalarm functions for each of Alarm 1 and 2.• Each function is set to ON by setting the following digitto "1":• The de-energized output alarm function is used for energizingor de-energizing the alarm relay to be closed. Whilethis function is set to ON, when the alarm judgment showsthe ON status, the relay is opened, and when the alarmjudgment shows the OFF status, the relay is closed.Alarm latch (1: use, 0: not use)Alarm of input error status (1: use, 0: not use)De-energized output alarm (1: use, 0: not use)• The alarm latch is the function to keep the alarm ON,once the alarm judgment shows the alarm ON status.
