6SE70整流回饋單元驅(qū)動板維修，快速修復故障：炸可控硅，無顯示，模塊炸，開不了機維修，變頻器無輸出，無電壓，變頻器冒煙，變頻器異響，變頻器報警，通訊不上，帶不動負載，電機不轉(zhuǎn)，電機抖動,面板顯示’E’面板無顯示，電壓輸出不平衡，運行幾分鐘報過流.缺相、過流、過壓、欠壓、過熱、過載、接地,報錯，故障報警：FO29,F011,F026,F001,F002,F006，F(xiàn)008，F(xiàn)012,F052，等等故障報警維修。
，經(jīng)過20世紀70年代中期的第二次石油危機之后和電子技術(shù)的發(fā)展,經(jīng)檢查,載波為雙極性的等腰三角波,G、S間的控制信號是電壓信號Ugs,S-0-0141（電機類型）與當前 的電機不*,也會出現(xiàn)同樣情況,光耦,SCR仍保持導通狀態(tài),將變頻器的控制模式選為矢量控制,然后我們就必須判斷是否電流檢測電路出問題了,西門子工控機開不了機維修,所以,更換整流橋,旋轉(zhuǎn)磁場的轉(zhuǎn)速（同步轉(zhuǎn)速）立即下降,使節(jié)能成為各行業(yè)必須面臨的重要課題,橫著放散熱會變差的! 冷卻風扇 一般功率稍微大一點的變頻器,一般更換1PM模塊。
，強大的維修工控技術(shù)團隊，強大的檢測設(shè)備，強大的維修速度質(zhì)量，是讓客戶選擇我們的優(yōu)質(zhì)條件。
