만복철강MHV1050A개선기 문제점

<p> </p><p>만복철강MHV개선기 균배축 상하모타소음 관련 확인결과보고입니다. 회전센사 A.B는 plc에서 정상 입니다. 상승시나 하강시에 감속기와 모든 베어링도 문제없읍니다. 단지 스톱시에 브레이크가 스톱과동시에 인버터의 프리런 스톱이 되어야하는데 브레이크가 작동후에 인버터가 잠시구동을하려다가 정지하는것입니다. 프리런스톱이 릴레이나 plc나 무엇으로 인버터에 지령하는지 접점이 어디에서 하는지를 알고싶읍니다. 그부위의 회로를 부탁드립니다. 동영상을 확인바랍니다</p><p> </p><p><span style="color: #36373c;">만복철강 개선가공기  MHV1050 고장건</span></p><p>전기회로 첨부합니다 <br><span style="color: #36373c;">상승,하강 모타
