Abstract: An inverter device is provided which is capable of more quickly raising an internal temperature of an electrolytic capacitor within a permissible range of a ripple voltage to shorten a non-operating time. The inverter device includes an electrolytic capacitor, an inverter circuit, a temperature sensor, and a control device. When the ambient temperature of the electrolytic capacitor detected by the temperature sensor is lower than a predetermined temperature, the control device on-drives specific switching elements of the inverter circuit before the start of a normal operation of a motor, and executes a warming up operation of allowing a current capable of controlling a ripple voltage of a DC voltage within a permissible range to flow through the motor at a predetermined rate of increase while keeping the motor stopped.

Abstract: [Problem] An inverter device is provided which is capable of more quickly raising an internal temperature of an electrolytic capacitor within a permissible range of a ripple voltage to shorten a non-operating time. [Solution] The inverter device includes an electrolytic capacitor 1, an inverter circuit 2, a temperature sensor 4, and a control device 3. When the ambient temperature of the electrolytic capacitor 1 detected by the temperature sensor 4 is lower than a predetermined temperature, the control device 3 on-drives specific switching elements of the inverter circuit 2 before the start of a normal operation of a motor 5, and executes a warming up operation of allowing a current capable of controlling a ripple voltage of a DC voltage within a permissible range to flow through the motor 5 at a predetermined rate of increase while keeping the motor 5 stopped.

Abstract: A controller for an actuator includes a lock detecting unit configured to detect a lock state of a motor and an abnormality detecting unit configured to detect an abnormality of the actuator. The abnormality detecting unit determines that an abnormality of the actuator is detected when it is determined that an operating position of the actuator does not change between a first lock position at which the lock state of the motor in a first rotation direction is detected and a second lock position at which the lock state of the motor in a second rotation direction is detected.
