修好西門子6SE70變頻器啟動后電機無力;變頻器的電子元器件使用壽命由于環境因素和使用條件的不同而有差異。在對臺安變頻器維修時,我們要具有豐富的經驗,這樣能夠快速的判斷出問題的原因所在,通過逐步排查明確故障問題的原因,對于一些變頻器設備使用公司來說,掌握一些常見的故障問題及處理方法,也有利于變頻器維修維護工作。
在此,恒稅電氣站為大家做了一些總結:首先,熟悉數控系統的人可能都會發現,關于變頻器維修,目前碰到故障比較多的是N2系列,常見的故障代碼包括過電流OC。造成這種情況的原因有很多種:比如電機出現故障,加速的時間過短,檢測到ct出現損壞,都有可能導致這種情況的出現。
變頻器維修這幾點要注意
一旦遇到此類故障時,常用的確定故障源的辦法通常是在不拖動電機的情況下開始運行變頻器,并同時測量輸出電壓,確定是電機有問題,還是變頻器出現了故障。假如是變頻器故障我們還是判斷是PIM模塊損壞引起的故障還是檢測電流誤檢引起的故障。我們通過測量,就能判斷出PIM模塊的好壞,但值得注意的是我們不能忽略對驅動電路波形的測量。
