Abstract
본 발명은 영구자석 동기모터의 엔코더에서 출력되는 이상 상태신호를 감지하도록 한 영구자석 동기모터의 엔코더신호 이상 검출장치에 관한 것으로서, 마이크로 프로세서가 U상 엔코더신호 검출부, V상 엔코더신호 검출부 및 W상 엔코더신호 검출부로 입력되는 U상, U/상 또는 V상, V/상 또는 W상, W/상이 정상적으로 입력되는 지를 하드웨어적으로 감지한 후 정상적으로 입력되면 상기한 U상, V상, W상이 정상적인 펄스열을 가지면서 출력되는 지를 소프트웨어적으로 감지하여 엔코더신호 이상 상태를 보다 정확하게 검출할 수 있는 효과가 있다.The present invention relates to an encoder signal abnormality detection device of a permanent magnet synchronous motor for detecting an abnormal state signal output from the encoder of the permanent magnet synchronous motor, wherein the microprocessor includes a U phase encoder signal detector, a V phase encoder signal detector, and a W phase. If the U phase, U / phase or V phase, V / phase or W phase and W / phase inputted to the encoder signal detection unit are detected in hardware and normally input, then the U phase, V phase, and W phase are normal. Software can detect whether the output has a pulse train can detect the abnormal state of the encoder signal more accurately.
