西門子840D系統NCU壞（十年硬件修理檢測），德國840D西門子NCU數控單元，是西門子系統中央控制單元，負責NC所有的功能，機床的邏輯控制，還有和MMC的通訊，它由一個COM CPU板、一個PLC CPU板和一個DRIVE板組成。NCU上面設置了OPI、MPI、Profibus接口。
840D系統NCU正常情況下，系統上電開機后，NCU會進行自檢，數碼管數字跳動，LED指示燈會閃爍，自檢結束無問題后，數碼管顯示6，兩個綠燈亮。
840D數(shu)控(kong)NCU常見故障：送電瞬(shun)間所(suo)(suo)有(you)(you)(you)燈(deng)都(dou)亮(liang)，但是數(shu)碼(ma)管(guan)無顯(xian)示(shi)(shi)(shi)，然后所(suo)(suo)有(you)(you)(you)燈(deng)瞬(shun)間變暗；POK燈(deng)熄滅(mie)，數(shu)碼(ma)管(guan)不(bu)亮(liang)，NCU板(ban)(ban)子H1,H2燈(deng)全亮(liang)的故障， NCU不(bu)能(neng)啟(qi)動，數(shu)碼(ma)管(guan)顯(xian)示(shi)(shi)(shi)1，數(shu)碼(ma)管(guan)顯(xian)示(shi)(shi)(shi)3，數(shu)碼(ma)管(guan)顯(xian)示(shi)(shi)(shi)4，LED燈(deng)亮(liang)5，指示(shi)(shi)(shi)燈(deng)全閃(shan)，自(zi)檢無法通過(guo)，數(shu)碼(ma)管(guan)顯(xian)示(shi)(shi)(shi)8，還有(you)(you)(you)，偶爾會(hui)發(fa)生(sheng)NCU無法完成自(zi)檢情況，并且會(hui)出現(xian)120202或者120201報(bao)警，顯(xian)示(shi)(shi)(shi)“等待NC/PLC聯接”，觀(guan)察機(ji)床面板(ban)(ban)，發(fa)現(xian)MCP面板(ban)(ban)燈(deng)不(bu)停閃(shan)爍。
