Abstract

모터구동회로를 인에이블시키는 인에이블 신호를 제2상 제어신호를 반전시킨 신호와 앤드연상한 후, 그 결과를 제1상 제어신호와 앤드연산하여 상기 모터 구동회로의 제1상 입력단자에 입력하고, 또한, 제1상 제어신호를 반전시킨 신호와 앤드연상하여 상기 모터 구동회로의 제2상 입력단자에 입력하여 제어불가 상태가 생기지 않게 한다.The AND signal for enabling the motor driving circuit is AND-associated with the signal inverting the second phase control signal, and the result is AND-operated with the first phase control signal and input to the first phase input terminal of the motor driving circuit. In addition, an AND association with the inverted signal of the first phase control signal is input to the second phase input terminal of the motor driving circuit so that an uncontrollable state does not occur.
