現(xiàn)在采用PLC控制的機(jī)床是越來(lái)越多，運(yùn)用PLC的控制能簡(jiǎn)化電路，使設(shè)計(jì)更加簡(jiǎn)單，安全，可靠。一些高級(jí)的PLC具備了各種接口以實(shí)現(xiàn)連機(jī)，上網(wǎng)等功能。使得人們可以遠(yuǎn)程控制設(shè)備。那么，如何才能設(shè)計(jì)好一臺(tái)由PLC控制的機(jī)床呢
主電路是給異步電動(dòng)機(jī)提供調(diào)壓調(diào)頻電源的電力變換部分，變頻器的主電路大體上可分為兩類：電壓型是將電壓源的直流變換為交流的變頻器，直流回路的濾波是電容。
模擬量，如電流、電壓、溫度、壓力等等，它的大小是連續(xù)變化的。工業(yè)生產(chǎn)，特別是連續(xù)型生產(chǎn)過(guò)程，常要對(duì)這些物理量進(jìn)行控制。

異步電動(dòng)機(jī)用變頻器調(diào)速運(yùn)轉(zhuǎn)時(shí)的結(jié)構(gòu)圖如圖1所示。通常由變頻器主電路（IGBT、BJT、或GTO做逆變?cè)┙o異步電動(dòng)機(jī)提供調(diào)壓調(diào)頻電源。此電源輸出的電壓或電源及頻率，由控制回路指令進(jìn)行控制。而控制指令則根據(jù)外部的運(yùn)轉(zhuǎn)指令進(jìn)行運(yùn)算獲得。對(duì)于需要精密速度或快速響應(yīng)的場(chǎng)合，運(yùn)算還應(yīng)包含由變頻器主電路和傳動(dòng)系統(tǒng)檢測(cè)出來(lái)的信號(hào)和保護(hù)電路信號(hào)，即防止因變頻器主電路的過(guò)電壓，過(guò)電流引起的損壞外就，還應(yīng)保護(hù)異步電動(dòng)機(jī)及傳動(dòng)系統(tǒng)等
一類交流接觸器對(duì)應(yīng)的控制對(duì)象是無(wú)感或微感負(fù)荷，如白熾燈、電阻爐等；二類交流接觸器用于繞線式異步電動(dòng)機(jī)的起動(dòng)和停止；三類交流接觸器的典型用途是鼠籠型異步電動(dòng)機(jī)的運(yùn)轉(zhuǎn)和運(yùn)行中分?jǐn)?；四類交流接觸器用于籠型異步電動(dòng)機(jī)的起動(dòng)、反接制動(dòng)、反轉(zhuǎn)和點(diǎn)動(dòng)。

初學(xué)時(shí)可以編一些簡(jiǎn)單的梯形圖，如觸點(diǎn)的與、或、輸出等，在PLC的機(jī)器里運(yùn)行一下。成功了就會(huì)增加你學(xué)習(xí)的興趣、和信心。然后再把PLC的主要功能逐個(gè)運(yùn)用一次，比如高速計(jì)數(shù)器，你可以用PLC本身的脈沖輸出端接到高速計(jì)數(shù)器的輸入端，下載編好的梯形圖，打開(kāi)變量觀察窗口，運(yùn)行程序，觀察計(jì)數(shù)的值是否正確。經(jīng)過(guò)了這樣的實(shí)踐，你基本上知道PLC到底能做哪些事情了，在實(shí)際的工控應(yīng)用中就能做到胸有成竹了
模擬量，如電流、電壓、溫度、壓力等等，它的大小是連續(xù)變化的。工業(yè)生產(chǎn)，特別是連續(xù)型生產(chǎn)過(guò)程，常要對(duì)這些物理量進(jìn)行控制。
