 SINUMERIK 840D采(cai)用特(te)殊的三CPU結構：人(ren)機通信CPU、數字控制CPU（NC-CPU）和可編(bian)程邏輯控制器CPU（PLC-CPU）。如圖2所示MMC-CPU在(zai)OP012人(ren)機界面內，NC-CPU和PLC-CPU集成在(zai)NCU572內。

    以NCU572為(wei)核心(xin)，電(dian)(dian)(dian)源(yuan)模塊(kuai)采用SIMODRIVER 611D，電(dian)(dian)(dian)源(yuan)模塊(kuai)主要為(wei)NCU和給611D數(shu)(shu)字(zi)驅動(dong)(dong)提(ti)供控制(zhi)和動(dong)(dong)力電(dian)(dian)(dian)源(yuan)，產生母(mu)線電(dian)(dian)(dian)壓，同時監(jian)測電(dian)(dian)(dian)源(yuan)和模塊(kuai)的(de)(de)狀態(tai)。后面有三(san)個進給模塊(kuai)通(tong)過驅動(dong)(dong)總線接(jie)(jie)口(kou)與(yu)NCU572掛(gua)接(jie)(jie)，數(shu)(shu)控和驅動(dong)(dong)的(de)(de)接(jie)(jie)口(kou)信號為(wei)數(shu)(shu)字(zi)量，分(fen)別驅動(dong)(dong)兩對鉆頭(tou)的(de)(de)Y方(fang)向(xiang)位置電(dian)(dian)(dian)機(ji)（M1,M2,M3,M4）和X方(fang)向(xiang)位置電(dian)(dian)(dian)機(ji)M5。同時NCU572又通(tong)過PROFIBUS現場總線與(yu)OP012人機(ji)界(jie)面、S7-300PLC及控制(zhi)電(dian)(dian)(dian)機(ji)轉(zhuan)速的(de)(de)變頻器連接(jie)(jie)在一起。
