Abstract

본 발명은 전송회선과, 모터 엔코더로부터 각각 병렬로 입력되는 복수 개의 반전 및 비반전신호쌍 중 비반전 신호만 검출하여 시리얼신호로 변환시킨 다음 상기 전송 회선으로 출력하는 인코딩부와, 상기 전송 회선을 통해 입력되는 상기 시리얼 신호를 다시 복수 개의 반전 및 비반전신호쌍으로 변환시켜 출력하는 디코딩 부로 구성된 모터 엔코더의 출력신호 젊신호에 관한 것으로서, 하나의 전송회선을 통해 모터 엔코더에서 출력되는 복수 개의 패럴랠 신호를 모터 컨트롤러로 전송하기 때문에 전송회선의 부피가 작아 설치에 제한을 받지 않고, 단선의 위험이 크게 줄어들어 시스템의 신뢰성이 증가하며, 상기 전송 회선이 단선되어도 수리가 용이한 잇점이 있다.The present invention provides an encoding apparatus comprising: an encoding unit for detecting only a non-inverted signal among a plurality of inverted and non-inverted signal pairs input in parallel from a transmission line and a motor encoder, converting the detected non-inverted signal into a serial signal, and outputting the serial signal to the transmission line; And a decoder for converting the serial signal input through the inverter to a plurality of inverted and non-inverted signal pairs and outputting the inverted and inverted signal pair. The output signal of the motor encoder includes a plurality of parallels Since the signal is transmitted to the motor controller, the volume of the transmission line is not limited so that the installation is not limited, the risk of disconnection is greatly reduced, reliability of the system is increased, and repair is easy even if the transmission line is disconnected.
