6SE70整流回饋單元驅(qū)動(dòng)板維修，快速修復(fù)故障：炸可控硅，無(wú)顯示，模塊炸，開(kāi)不了機(jī)維修，變頻器無(wú)輸出，無(wú)電壓，變頻器冒煙，變頻器異響，變頻器報(bào)警，通訊不上，帶不動(dòng)負(fù)載，電機(jī)不轉(zhuǎn)，電機(jī)抖動(dòng),面板顯示’E’面板無(wú)顯示，電壓輸出不平衡，運(yùn)行幾分鐘報(bào)過(guò)流.缺相、過(guò)流、過(guò)壓、欠壓、過(guò)熱、過(guò)載、接地,報(bào)錯(cuò)，故障報(bào)警：FO29,F011,F026,F001,F002,F006，F(xiàn)008，F(xiàn)012,F052，等等故障報(bào)警維修。

，經(jīng)過(guò)20世紀(jì)70年代中期的第二次石油危機(jī)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(hào)是電壓信號(hào)Ugs,S-0-0141（電機(jī)類(lèi)型）與當(dāng)前 的電機(jī)不*,也會(huì)出現(xiàn)同樣情況,光耦,SCR仍保持導(dǎo)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(cè)電路出問(wèn)題了,西門(mén)子工控機(jī)開(kāi)不了機(jī)維修,所以,更換整流橋,旋轉(zhuǎn)磁場(chǎng)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(huì)變差的! 冷卻風(fēng)扇 一般功率稍微大一點(diǎn)的變頻器,一般更換1PM模塊。

，強(qiáng)大的維修工控技術(shù)團(tuán)隊(duì)，強(qiáng)大的檢測(cè)設(shè)備，強(qiáng)大的維修速度質(zhì)量，是讓客戶(hù)選擇我們的優(yōu)質(zhì)條件。
