專門修復西門子6RA80驅動器上電面板無顯示處理方法；上電無顯示：
首先檢查充電電阻是否損壞，如果沒有阻值，就換掉充電電阻。如果充電電阻完好，看電源驅動板小燈和主控?板的小燈有沒有亮，這時如果沒亮則是開關電源故障，首先檢查開關管的電源輸入電阻和漏極的1歐電阻有沒有開路，以及18V穩壓管是否擊穿！如果正常，檢查開關電源的場效應管是否正常！如果正常，檢查震蕩芯片是否正常。也有可能是驅動電路故障或開關變壓器故障。主板到驅動板的排線也要檢查。再檢查不出來我就換電源驅動板了。
如果開關電源正常工作而上電無顯示，可以查一下操作屏是否有故障，方法是換屏試一試。
  2、上電顯示LU:表示欠壓，首先檢查變頻器輸入電壓是否符合供電標準，如果供電電壓正常，檢查有否缺相。如果不缺相，檢查變頻器內電解電容是否正常？整流橋是否正常?再不然就是電源驅動板故障了。
