今天專(zhuān)門(mén)試了一下，把P L C和變頻器的通訊線(xiàn)拔掉，按寸行按鈕機器結果高速運轉，沒(méi)有寸行速度，按運行按鈕還是高速運轉。P L C里面是設置了運行啟動(dòng)后有另外一個(gè)輔助電機工作，寸行速度輔助電機不會(huì )工作。今天又出現了運行啟動(dòng)后又是寸行速度工作，斷電重啟也不行，最后沒(méi)辦法把屏和PL C的通訊線(xiàn)拔掉重新插上又正常運行了，哎！到底問(wèn)題在哪？請各位師傅 多多指教

把你整個(gè)系統的電路圖貼出來(lái)，特別是PLC與變頻器的連接，把變頻器的參數設置貼出來(lái)�？礃幼幼冾l器與PLC之間是混合連接，這種逗逼模式特別麻煩！
我覺(jué)得這種設計的唯一目的，就是把系統搞復雜，不讓維修人員搞懂。
