西門子直流變頻器啟動顯示報警F004當天修復故障檢測處理;西門子直流變頻器6RA70報警F004代碼原因及故障排除方法,6RA70報警代碼故障咨詢,西門子6RA70報警F004代碼,6RA70顯示F004,F004不能復位,F004故障查詢,F004什么原因引起
用戶在使用過程中,經常會碰見6RA70直流變頻器報警F004電源檢測故障,復位不了。
故障原因:F004報警激活條件是三相進線電源電壓偏低20%左右。三相電壓檢測由分壓電阻送到運算比較放大器至CPU處理器判斷信號的高低電平,激活報警代碼。直流調速器燒可控硅快容保護器燒毀,上電運行就會顯示F004代碼,不能復位,電源取樣信號開路,上電也會報警F004。CUD1控制板損壞也會報警激活。
故障方法排除:
1、觀察R015顯示值,380V輸入調速器,正常是在380~400V。
2、更換脈沖觸發電源板
3、更換CUD1控制板(ban)
