Alarm Output
After an inverter alarm is linked to a DO port, the alarm signal is delivered from the DO port when the inverter generates the alarm.
Because of permission restriction, log in as Advanced User. Choose .
- Before linking an inverter alarm to a DO port, ensure that the DO port is not set for other purposes. Otherwise, the setting will fail.
- After the function is enabled, the DO port status may change and the alarm output may be abnormal if the SmartLogger restarts or powers off.
