Alarm Display When You Use External 24 V Power Supply
When you use an external 24 V power supply, the drive detects an alarm as shown in Table 5.5 if you set o2-23
[External 24V Powerloss Detection] and o2-26 [Alarm Display at Ext. 24V Power] for the main circuit power supply.
Set the alarm display as necessary.
