Abstract
Description
Claims (1)
- 제어신호를 입력하여 소정값으로 프로세트되고 모터로부터 발생되는 주파수신호를 클럭신호로 입력하여 제1주파수 신호를 발생하기 위한 제1계수수단; 제어신호를 입력하여 소정값으로 프리세트되고 샘플링 주파수를 128분주한 신호를 클럭신호로 입력하여 제2주파수 신호를 발생하기 위한 제2계수수단; 상기 제1주파수 신호에 의해서 리세트되고 상기 제2주파수 신호를 클럭신호로 하여 계수하여 소정값을 발생하기 위한 제3계수수단과; 상기 제3계수수단의 출력신호에 의해서 리세트되고 상기 샘플링 주파수를 64분주한 신호를 클럭신호로 입력하여 계수하여 기준주파수를 발생하기 위한 기준 주파수 발생수단; 상기 제1주파수 신호에 의해서 리세트되고 상기 샘플링 주파수를 128분주한 신호를 클럭신호로 하여 24분주하기 위한 24분주수단; 상기 제3계수수단의 출력신호에 의해서 리세트되고 상기 24분주수단의 출력신호를 클럭신호로 127다운 계수하여 회전수를 검출하기 위한 회전수 검출수단을 구비한 것을 특징으로 하는 스핀들 모의 주파수 발생 및 회전수 검출회로.
