Abstract
본 발명은 대기 상태를 갖는 모터속도제어장치에 관한 것으로서, 특히 전류 명령 검출부, 정지 전압 비교부, 출력 구동 논리부, 비교부 및 UVLO 단을 구비한 모터제어장치에 있어서, 전원 전압이 상기 UVLO 단의 설정 전압 이상이면 상기 전류 명령 검출부, 정지전압 비교부에 제 1 기조 전압을 구동 전원으로 공급하는 제 1 기준 전압 발생부 ; 상기 정지전압 비교부에서 상기 전류 명령 검출부에서 출력되는 전류 명령이 상기 정지전압 비교부에 설정된 정지전압 이하일 경우를 검출하는 검출수단 ; 및 상기 검출수단에 의해 전류 명령이 정지전압 이하가 검출된 경우에는 디스에이블 되고 이상인 경우에는 인에이블 되어 제 2 기준 전압을 발생하고 발생된 제 2 기준 전압을 상기 출력 구동 논리부, 비교부의 구동 전원으로 공급하는 제 2 기준 전압 발생부를 구비하는 것을 특징으로 한다.The present invention relates to a motor speed control apparatus having a standby state, and more particularly, to a motor control apparatus having a current command detecting unit, a stop voltage comparing unit, an output driving logic unit, a comparing unit, and a UVLO stage, A first reference voltage generator for supplying the first command voltage to the current command detector and the stop voltage comparator as a driving power source; Detecting means for detecting when the current command output from the current command detecting unit in the stop voltage comparing unit is equal to or less than a stop voltage set in the stop voltage comparing unit; And a second reference voltage generating unit which generates a second reference voltage and outputs the generated second reference voltage to the output drive logic unit, the driving power supply of the comparison unit, And a second reference voltage generating unit for supplying the second reference voltage to the second reference voltage generating unit.
따라서, 본 발명에서는 전류 명령이 임의 설정된 정지전압 이하일 경우에는 제 1 기준 전압 발생부는 전류 명령 검출부와 정지전압 비교부만을 인에이블 시키고, 나머지회로들은 대기 상태로 디스에이블 시킴으로 모터 정지시의 소비 전류를 대폭 감소시키는 효과가 있다.Accordingly, in the present invention, when the current command is equal to or less than a predetermined stop voltage, the first reference voltage generating unit enables only the current command detecting unit and the stop voltage comparing unit, and the remaining circuits are disabled in the standby state, The effect is greatly reduced.
