  • Publication number: 20240088814
    Abstract: When a DC power source fails, the following controls are performed. The normal control is resumed when an inverter input voltage recovers before a standby period elapses after a power failure time. A power source relay is turned off when the standby period elapses without recovery of the voltage. The power source relay is turned on again when a power source relay off period has elapsed from a turn-off time. The normal control is resumed when the inverter input voltage recovers at the turn-on time. The normal control is resumed when the inverter input voltage recovers before the power source relay on period elapses from the turn-on time. The power source relay is turned off, and driving of the actuator is stopped, when the power source relay on period passes without recovery of the voltage.
