ABB直流調速器DCS50*修理中心，故障分析:如果需要弱磁先要找出在大弱磁點的小勵磁電流(通常寫在電機銘牌上)。在調試向導中設置參數Field Low Trip(4.06)=10%，小于小勵磁電流，否則在弱磁過程中會出現故障F12。也就是說這是調試的時候參數沒有設置正確。
 
·這也可能是緊接著主電源欠壓故障(F9/A2)出現的。讀取故障記錄，DCS400采用了新方法來監測主電源電壓。可能是額定電樞電壓與主電源電壓實際值不對應，按手冊2.2節表2.2.4修改或將參數Net UndervTrip(1.10)的值調小。這和變頻器一樣，當斷電的時候CPU工作電源是較慢斷電的，所以它以關機后會檢測到勵磁電壓下降或丟失，就會報警說勵磁電流不足。
 
·電機的自動(dong)調整檢測到Field CurKP(4.03)值(zhi)很高(gao)，這可(ke)能導(dao)致勵磁(ci)電流振蕩，同時傳動(dong)會(hui)由于超(chao)調F13或欠(qian)調F12而跳閘。將參數Field Cur KP(4.03)值(zhi)調小并且/或Field CurTI (4.04)的值(zhi)調大(da)。可(ke)以使(shi)用這兩個參數的缺省值(zhi)。在些(xie)(xie)要注意的是，這與歐陸直流調速器維修還是有些(xie)(xie)不(bu)一樣的，且不(bu)說電路結構、檢測方(fang)式(shi)(shi)不(bu)一樣，就單單是對同一個故(gu)障(zhang)或者現象的表達方(fang)式(shi)(shi)都不(bu)一樣，所以對這些(xie)(xie)專業術(shu)語還要多加理解(jie)才行。
