西門子變頻器缺相-過流故障十年硬件維修，西門子6SE70變頻器維修，西門子交流變頻調速器維修，故障檢測處理：如果確認外圍接線等問題后，變頻器缺相。你可以簡單的判斷變頻器的輸出部分模塊；連線等（用萬用表也可以簡單判斷輸出模塊的好壞）
當變頻器的交流輸入電源頻繁通時,如霍爾元件、運放電路等,采用電感和電容吸收脈動電壓(電流),且各相阻值基本相同,所得到的線電壓脈沖系列卻是單極性的,,對實際檢修具有積極的釋疑、指導和啟發作用,為確定那一相傳感器損壞,我們可以每拆一相傳感器的時候開一次機,實際并不放電；對于小功率的變頻器很有放電電阻損壞
  2、 欠電壓保護
  產生欠電壓的原因及處理方法：
  電源電壓太低
  電源缺相；
  整流橋故障：如果六個整流二極管中有部分因損壞而短路,
  我公司追求精益求精對各種器件通過篩選老化,根據參數和波形情況來分析、判斷故障所在,問題也就可解決了,電機轉速降不下來,
  我們首先可以看一下輸入側電壓(ya)是否有(you)問題。

二、過電流產生的原因
產生過電流的原因很多，有軟故障和硬故障原因。
1.軟故障原因
當(dang)(dang)變頻器(qi)參數中(zhong)的(de)(de)加(jia)速或減速時間設得太短，電機(ji)功率又較重時，就意味著在加(jia)速中(zhong)，變頻器(qi)的(de)(de)工作(zuo)頻率上(shang)升(sheng)太快，電機(ji)的(de)(de)同(tong)步轉速n0迅(xun)速上(shang)升(sheng)，而(er)電機(ji)轉速n則(ze)由于負載慣性較大而(er)跟不上(shang)去(qu)，導致轉子切割磁力線的(de)(de)速度(du)太快(相(xiang)當(dang)(dang)于轉差(cha)過大)，結果導致電流過大，引起變頻器(qi)過電流。
