• Relay output
• 30 Vdc, 10 mA to 1 A
• 250 Vac, 10 mA to 1 A
• Minimum load: 5 V, 10 mA (Reference value)
Note:
Do not set functions that frequently switch ON/OFF to MFDO (M1 to M6) because this will
decrease the performance life of the relay contacts. Yaskawa estimates switching life at
200,000 times (assumes 1 A, resistive load).

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 3.10 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.
