位置反饋是數(shù)控機(jī)床的重要組成部分，由位置反饋元件將位置信號(hào)反饋給數(shù)控裝置，實(shí)現(xiàn)位置的閉環(huán)控制。使用編碼器的位置環(huán)稱之為半閉環(huán)位置控制系統(tǒng)，是通過(guò)檢測(cè)絲杠的旋轉(zhuǎn)角度間接反饋位置信號(hào)的;使用光柵尺作為反饋元件的稱之為全閉環(huán)位置控制系統(tǒng)，是通過(guò)檢測(cè)進(jìn)給滑臺(tái)的實(shí)際位置直接反饋位置信號(hào)的。
可編程控制器簡(jiǎn)稱PLC。隨著科技技術(shù)的發(fā)展，未適應(yīng)多種，小批量生產(chǎn)的需求而產(chǎn)生發(fā)展起來(lái)的一種新型的工業(yè)控制裝置。

交流回路中的電容器投入電網(wǎng)或從電網(wǎng)中切除時(shí)，接觸器選擇應(yīng)考慮電容器的合閘沖擊電流。一般地，接觸器的額定電流可按電容器的額定電流的1.5倍選取，型號(hào)選CJ10、CJ20等。
近幾年來(lái)，可編程序控制器(PLC)以其可靠性高、適應(yīng)性強(qiáng)、靈活性好、編程簡(jiǎn)單、容易掌握等特性，在各個(gè)領(lǐng)域發(fā)揮越來(lái)越重要的作用。在PLC控制系統(tǒng)中，PLC作為主要控制設(shè)備，必然與控制對(duì)象中各種輸入信號(hào)(如按鈕、限位開(kāi)關(guān)、拔動(dòng)開(kāi)關(guān)、繼電器的觸點(diǎn)及其它檢測(cè)信號(hào)等)和輸出設(shè)備(如繼電器線圈、接觸器線圈、電磁閥等執(zhí)行元件)相關(guān)聯(lián)。在實(shí)際工作中，由于受PLC應(yīng)用系統(tǒng)規(guī)模的限制，PLC輸入/輸出點(diǎn)數(shù)往往不夠用。為此若采用擴(kuò)展輸入/輸出單元或更換點(diǎn)數(shù)更多的PLC來(lái)解決有時(shí)又不合算，為了降低系統(tǒng)硬件的成本，常常采用各種技巧減少系統(tǒng)占用的輸入/輸出點(diǎn)數(shù)，相當(dāng)于擴(kuò)展了PLC的I/O點(diǎn)數(shù)。本文從硬件、軟件兩個(gè)方面介紹在不增加硬件情況下"擴(kuò)展"PLC I/O點(diǎn)數(shù)的幾種方法。
電流型是將電流源的直流變換為交流的變頻器，其直流回路濾波是電感。它由三部分構(gòu)成，將工頻電源變換為直流功率的"整流器"，吸收在變流器和逆變器產(chǎn)生的電壓脈動(dòng)的"平波回路"，以及將直流功率變換為交流功率的"逆變器"

對(duì)所有接線端檢查、緊固，防止松動(dòng)引起嚴(yán)重發(fā)熱現(xiàn)象的發(fā)生。對(duì)輸入(包括輸出)端、整流模塊、逆變模塊、直流電容和快熔等器件進(jìn)行全面檢查、參數(shù)測(cè)定，發(fā)現(xiàn)燒毀或參數(shù)變化大的器件應(yīng)及時(shí)更換。對(duì)變頻器內(nèi)風(fēng)扇轉(zhuǎn)動(dòng)狀況、要經(jīng)常仔細(xì)檢查，斷電后，用手轉(zhuǎn)動(dòng)風(fēng)葉，觀察軸承有無(wú)卡死或轉(zhuǎn)動(dòng)不靈活現(xiàn)象，必要時(shí)更換處理。仔細(xì)檢查控制電路板上電子元器件，檢查和處理脫焊、變色、鼓肚、開(kāi)裂、斷線(印刷板線路)等異常現(xiàn)象，必要時(shí)對(duì)外表異常的元器件，可從電路板上脫焊測(cè)量檢查或更換。
PLC與繼電器控制邏輯的性能和價(jià)格進(jìn)行相比較：控制邏輯：繼電器控制邏輯采用硬接線邏輯，利用繼電器機(jī)械觸點(diǎn)的串聯(lián)或并聯(lián)及延時(shí)繼電器的滯后動(dòng)作等組合成控制邏輯，其連線多而復(fù)雜，體積大，功耗大，一旦系統(tǒng)構(gòu)成后，想再改變或增加功能都很困難。另外繼電器觸點(diǎn)數(shù)目有限，每只一般只有4～8對(duì)觸點(diǎn)，因此靈活性和擴(kuò)展性都很差。而PLC采用存儲(chǔ)邏輯，其控制邏輯以程序方式存儲(chǔ)在內(nèi)存中，要改變控制邏輯，只需改變程序，故稱為"軟接線"，其連線少，體積小，加之PLC中每只軟繼電器的觸點(diǎn)數(shù)理論上無(wú)限制，因此靈活性和擴(kuò)展性都很好。PLC由中大規(guī)模集成電路組成，功耗小。
