PROBLEM TO BE SOLVED: To provide an actuator drive device capable of properly stopping the driving of an electromagnetic actuator when an abnormality is detected.SOLUTION: The actuator drive device includes: an actuator drive circuit connected with an electromagnetic actuator; a step-up circuit which outputs an external power supply voltage to the actuator drive circuit while stepping up; a regeneration circuit which makes the step-up circuit regenerate a counter-electromotive current generated in the electromagnetic actuator; and a processor which drives the electromagnetic actuator by controlling the actuator drive circuit. The processor switches the stop processing for stopping the driving of the electromagnetic actuator by the abnormal state of an input signal system. |
