PLC是三菱FX3U
伺服每轉一圈C相會(huì )輸出1脈波, 請教怎么讀取這訊號?
C相PCO輸出是5V, /PCO輸出是-5V, 估計需要中間接一個(gè)差分信號器----型號還不明

問(wèn)題1, 從差分信號出來(lái)接去X0, X0對應C235, 那代表轉轉一圈C235就會(huì )有一次數值嗎?
問(wèn)題2,  X0也會(huì )亮燈嗎?
問(wèn)題3, 因為目前馬達轉動(dòng)X(jué)0和C235是沒(méi)有接收到訊號!
問(wèn)題4, 使用三菱PLC的話(huà), 差分信號器有指定什么型號或規格嗎?
求指教!~!~! 謝謝

FX3U本體只能接收集電極開(kāi)路信號，如果要接收差分信號請考慮2HC模塊
