產品簡介：

好西門子直流驅動器上電報警無法復位故障(zhang)(zhang)(zhang)處理(li)；對于(yu)(yu)這個故障(zhang)(zhang)(zhang)現象，屬(shu)(shu)于(yu)(yu)磁(ci)場欠流故障(zhang)(zhang)(zhang)，應(ying)當(dang)歸屬(shu)(shu)于(yu)(yu)硬件(jian)故障(zhang)(zhang)(zhang)，就(jiu)是勵磁(ci)單元部分故障(zhang)(zhang)(zhang)。如果(guo)是新買的產品，趁還沒(mei)(mei)有(you)(you)過(guo)(guo)保修(xiu)(xiu)期，要及時與ABB售后(hou)維修(xiu)(xiu)服務(wu)部門(men)聯系，不(bu)然時間過(guo)(guo)了自己要花錢維修(xiu)(xiu)。 至于(yu)(yu)電機(ji)，應(ying)當(dang)檢測電機(ji)磁(ci)場繞組是否正常(chang)，匝間有(you)(you)無短(duan)路，有(you)(you)無對地(di)等。經(jing)過(guo)(guo)以(yi)上這一系列(lie)排查，都沒(mei)(mei)有(you)(you)找到(dao)故障(zhang)(zhang)(zhang)點，最(zui)后(hou)檢測到(dao)勵磁(ci)回路傳感(gan)器電路開路，修(xiu)(xiu)復后(hou)試機(ji)正常(chang)。

這也可能是緊跟著主(zhu)電(dian)(dian)源欠(qian)壓故障(F9/A2)出(chu)現的(de)(de)，電(dian)(dian)壓不足會(hui)引起電(dian)(dian)流不足。建議可以(yi)從操作器上讀取(qu)故障記錄(lu)，DCS400采用(yong)了新方法來(lai)監測主(zhu)電(dian)(dian)源電(dian)(dian)壓。有可能是額定電(dian)(dian)樞電(dian)(dian)壓與主(zhu)電(dian)(dian)源電(dian)(dian)壓實際(ji)值不對應，主(zhu)板檢查到了欠(qian)壓。可嘗試將參數Net Underv Trip(1.10)的(de)(de)值改(gai)變到合(he)適數值。

另外一(yi)個原因，電機(ji)的自動調(diao)整檢測(ce)到Field CurKP(4.03)值很高，這可(ke)能導(dao)致(zhi)勵磁(ci)電流振蕩，同時傳動會由于超調(diao)F13或欠調(diao)F12而跳閘。將參(can)數(shu)(shu)Field Cur KP（4.03)值調(diao)小并且/或Field CurTI (4.04)的值調(diao)大。并且可(ke)以使(shi)用這兩個參(can)數(shu)(shu)的缺省（默(mo)認）值試一(yi)下。

    對于(yu)這個故(gu)(gu)障(zhang)(zhang)現象(xiang)，屬(shu)于(yu)磁場欠流故(gu)(gu)障(zhang)(zhang)，應當歸屬(shu)于(yu)硬件故(gu)(gu)障(zhang)(zhang)，就(jiu)是勵磁單(dan)元部(bu)分故(gu)(gu)障(zhang)(zhang)。如果(guo)是新買的產(chan)品(pin)，趁還沒(mei)(mei)有(you)過(guo)保修期，要(yao)及時與ABB售后維修服務部(bu)門(men)聯系(xi)，不然時間過(guo)了(le)自己要(yao)花錢維修。 至于(yu)電(dian)機，應當檢測(ce)電(dian)機磁場繞(rao)組是否正常，匝間有(you)無短路(lu)(lu)，有(you)無對地(di)等。經(jing)過(guo)以上這一系(xi)列(lie)排查，都沒(mei)(mei)有(you)找到故(gu)(gu)障(zhang)(zhang)點，最(zui)后檢測(ce)到勵磁回路(lu)(lu)傳感(gan)器電(dian)路(lu)(lu)開路(lu)(lu)，修復后試機正常。

好西門子直流驅動器上電報警無法復位故障處理；電(dian)(dian)(dian)(dian)(dian)(dian)樞主電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)為三相全(quan)控橋的典(dian)型結構，由(you)三只雙單向(xiang)晶(jing)閘管模塊(kuai)組成，在電(dian)(dian)(dian)(dian)(dian)(dian)源輸入(ru)側與整流(liu)(liu)(liu)(liu)正(zheng)、負輸出(chu)端(duan)之間，并聯(lian)了R、C串聯(lian)尖波(bo)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)吸收網絡，以(yi)(yi)消除由(you)電(dian)(dian)(dian)(dian)(dian)(dian)網進(jin)入(ru)的有(you)害(hai)毛刺(ci)。電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)檢測電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)使用TA1、TA2兩只電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)互感器采集三相電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)信(xin)號，送后(hou)級CPU主板進(jin)行電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)比(bi)較，以(yi)(yi)形成電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)環閉環控制和輸出(chu)過流(liu)(liu)(liu)(liu)保護(hu)信(xin)號。在整流(liu)(liu)(liu)(liu)器輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)的正(zheng)端(duan)串接FLT分流(liu)(liu)(liu)(liu)器，供(gong)外接電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表，顯(xian)示運行工作電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)。晶(jing)閘管模塊(kuai)散熱風機的供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)由(you)X99端(duan)子(zi)引入(ru)AC 220V電(dian)(dian)(dian)(dian)(dian)(dian)源。
