Using control power supply
When the inverter and control circuit are powered from different sources (to leave fault indication) and the external operation is started (STF is turned ON), the OC1 error is displayed if the main circuit is not powered ON. Can I disable display of this error just as the initial type of the FR-A500 (A200)?
If the main circuit is powered OFF for some reason, does the inverter stop due to OC1?

Answer
You cannot disable the error display. The OC1 overcurrent alarm is displayed.
The condition to display this alarm is that the main circuit power supply is OFF and the main circuit DC bus voltage is low, and then the control power supply is turned ON.
When the main circuit power supply and control power supply are both ON and then the main circuit power supply is turned OFF, the inverter only shuts off the output and the OC1 alarm is not displayed.
