How do I set up output of alarm output 1 from the UP32A/UP35A/UP55A AL1 terminals (relay contact output)?

In the setup parameter ALM menu, set the AL1.S parameter to 4353 (AL01_L1).
[Supplement]
4321(ALM1) is the alarm status of ON when an alarm occurs, and OFF when normal.
4353(AL01) is the alarm status determined by applying the settings for alarm energize/de-energize, latch operation, and contact type to 4321(ALM1).
