Cause : Option fault comes when the AC power supply is connected to the terminal R/L1, S/L2, T/L3 accidentally when a
high power factor converter is connected. Appears when the switch for the manufacturer setting of the plug-in option is changed.
- Check that the AC power supply is not connected to the terminal R/L1, S/L2, T/L3 when a high power factor converter (FR-HC, MT-HC) or power regeneration common converter (FR-CV) is connected.
- Check the parameter (Pr. 30) setting and wiring.
