Undervoltage warning

When the power supply of the main circuit and control circuit is separated, does the undervoltage warning occur if the power failure occurs only at the main circuit? (Under the condition where power at the rated voltage is continually supplied to the control power supply)When the main circuit is normal and the control power supply is OFF, does the undervoltage warning occur by the time the capacitor runs out of charge?
Category : 


The undervoltage warning of the inverter is judged based on the voltage of the main circuit as follows. Power failure only at the main circuit: Output an undervoltage warningPower failure only at the control circuit: Not output an undervoltage warningWhen the control circuit is turned ON while the main circuit is OFF, an undervoltage warning is not output.
