西門子840DSL床子NCU控制器上電顯示8修復解決，西門子加工中心，鏜銑床，數控磨床，數控銑床修復專家分析處理；

西門子840DSLNCU出現的故障為上(shang)電之后數(shu)(shu)碼管(guan)(guan)(guan)無顯(xian)示(shi)，數(shu)(shu)碼管(guan)(guan)(guan)顯(xian)示(shi)“1",數(shu)(shu)碼管(guan)(guan)(guan)顯(xian)示(shi)“3"，數(shu)(shu)碼管(guan)(guan)(guan)顯(xian)示(shi)“8"，數(shu)(shu)碼管(guan)(guan)(guan)走“106"和“109"等。如果NCU出現上(shang)述報警均屬(shu)于NCU有故障，需要(yao)人士(shi)進行(xing)修理，NCU正常狀態為數(shu)(shu)碼管(guan)(guan)(guan)顯(xian)示(shi)“6"和兩個綠燈亮才屬(shu)正常。

數控(kong)機(ji)床(chuang)電(dian)氣設(she)備檢修是作為數控(kong)機(ji)床(chuang)維修電(dian)工必須熟練掌(zhang)握的重要技能之一。在(zai)實際工作中(zhong)，必須要了解數控(kong)機(ji)床(chuang)電(dian)氣設(she)備產生故障的原(yuan)因、分類(lei)，掌(zhang)握故障分析以及檢修的基(ji)本方法。

       數(shu)控機(ji)床電氣設(she)備產生故障原因(yin)及分類,數(shu)控機(ji)床電氣設(she)備在運(yun)行(xing)的(de)過程中(zhong)，需承受來自環境、操作(zuo)等諸(zhu)多不(bu)利因(yin)素影(ying)響(xiang)，造成或是出現許多故障，因(yin)此日常維(wei)護保養與檢(jian)修(xiu)是生產的(de)運(yun)行(xing)中(zhong)非常重要和不(bu)可少的(de)(de)(de)部分。由(you)于電(dian)(dian)(dian)氣故(gu)障的(de)(de)(de)類(lei)型非常(chang)(chang)多(duo)，且各(ge)有其特點，甚(shen)至可說數控(kong)(kong)機(ji)床維修人員在(zai)自(zi)己整個(ge)工作過程中(zhong)(zhong)很(hen)難遇到兩個(ge)形式(shi)、類(lei)型、性質相同故(gu)障。機(ji)床維修中(zhong)(zhong)電(dian)(dian)(dian)氣設備控(kong)(kong)制線路的(de)(de)(de)檢修方(fang)法,數控(kong)(kong)機(ji)床電(dian)(dian)(dian)氣設備在(zai)運行(xing)(xing)(xing)過程中(zhong)(zhong)出現(xian)故(gu)障，按故(gu)障的(de)(de)(de)原(yuan)因主要(yao)分為兩類(lei)：一類(lei)是(shi)由(you)于電(dian)(dian)(dian)器運行(xing)(xing)(xing)過程中(zhong)(zhong)機(ji)械(xie)振動，過電(dian)(dian)(dian)流熱效(xiao)應(ying)加速(su)電(dian)(dian)(dian)器元件的(de)(de)(de)絕緣老化變(bian)質，電(dian)(dian)(dian)弧(hu)燒損(sun)，長期動作自(zi)然(ran)磨損(sun)，周(zhou)圍環(huan)境溫度(du)和濕(shi)度(du)影響，金屬(shu)屑和油污等(deng)有害介質侵蝕，元件自(zi)身(shen)質量問題、自(zi)然(ran)壽命等(deng)原(yuan)因，造(zao)成電(dian)(dian)(dian)路與數控(kong)(kong)機(ji)床電(dian)(dian)(dian)氣不能正常(chang)(chang)運行(xing)(xing)(xing)的(de)(de)(de)自(zi)然(ran)故(gu)障，是(shi)客(ke)觀存在(zai)，不能避(bi)免的(de)(de)(de)。另一類(lei)是(shi)由(you)于數控(kong)(kong)機(ji)床電(dian)(dian)(dian)氣設備在(zai)運行(xing)(xing)(xing)中(zhong)(zhong)，受到不應(ying)有的(de)(de)(de)機(ji)械(xie)外(wai)力的(de)(de)(de)破(po)壞或因操(cao)作不當，安(an)裝不合(he)理而造(zao)成的(de)(de)(de)故(gu)障，也會造(zao)成數控(kong)(kong)機(ji)床事故(gu)，甚(shen)至危及人身(shen)安(an)全，均屬(shu)人為故(gu)障。

      從故(gu)(gu)障(zhang)(zhang)表(biao)象(xiang)上，一類(lei)機床(chuang)維修故(gu)(gu)障(zhang)(zhang)具有明顯(xian)的(de)(de)(de)(de)(de)外(wai)表(biao)特征(zheng)(zheng)(zheng)，如電動(dong)(dong)機，電器的(de)(de)(de)(de)(de)顯(xian)著發熱(re)、冒煙、散發出(chu)焦臭味或(huo)(huo)(huo)(huo)火花等是由于電動(dong)(dong)機、電器的(de)(de)(de)(de)(de)繞組過載，絕緣擊穿，短路或(huo)(huo)(huo)(huo)接地所引起(qi)的(de)(de)(de)(de)(de)，很(hen)容易被發現。另一類(lei)故(gu)(gu)障(zhang)(zhang)沒有明顯(xian)的(de)(de)(de)(de)(de)外(wai)部特征(zheng)(zheng)(zheng)，如在電氣線(xian)(xian)路中(zhong)電器元件(jian)調(diao)整不當，機械動(dong)(dong)作失(shi)靈，觸點(dian)及壓接線(xian)(xian)頭接觸不良或(huo)(huo)(huo)(huo)脫落以(yi)及某個小零件(jian)的(de)(de)(de)(de)(de)損壞、導線(xian)(xian)斷裂等原因所造成的(de)(de)(de)(de)(de)故(gu)(gu)障(zhang)(zhang)，或(huo)(huo)(huo)(huo)者(zhe)線(xian)(xian)路復雜(za)也容易出(chu)現此類(lei)故(gu)(gu)障(zhang)(zhang)，是控(kong)制線(xian)(xian)路的(de)(de)(de)(de)(de)主(zhu)要(yao)故(gu)(gu)障(zhang)(zhang)。這(zhe)類(lei)故(gu)(gu)障(zhang)(zhang)在實(shi)際中(zhong)經(jing)常碰(peng)到(dao)(dao)，由于沒有外(wai)表(biao)特征(zheng)(zheng)(zheng)，要(yao)尋找(zhao)故(gu)(gu)障(zhang)(zhang)點(dian)必須(xu)借助各類(lei)測(ce)量儀表(biao)和工具才能找(zhao)到(dao)(dao)故(gu)(gu)障(zhang)(zhang)點(dian)，而(er)一旦找(zhao)出(chu)故(gu)(gu)障(zhang)(zhang)點(dian)，只需簡單的(de)(de)(de)(de)(de)調(diao)整或(huo)(huo)(huo)(huo)修理就能立即恢復數(shu)控(kong)機床(chuang)電氣的(de)(de)(de)(de)(de)正(zheng)常運行。
