PROBLEM TO BE SOLVED: To achieve proper response even when a push-button-type selector switch is used for a motor control device for drive which responds only when selector signals in an order corresponding to a specific range order to prevent erroneous operation. SOLUTION: A selector signal generation device 6 is included between a push-button-type selector switch 7 and a motor control device 2 for drive. When a target range is specified by the selector switch 7, the selector signal generation device 6 successively generates selector signals corresponding to each range from a range adjacent to the side in the target range direction of a current range to the target range and hence the push-button-type selector switch 7 can be adopted as a selector switch. |
