用一般指令配合常用一般指令實(shí)現(xiàn)三相異步電動(dòng)機(jī)控制
按照三相異步電動(dòng)機(jī)控制原理圖（圖8-8）接線或用控制模板代替。圖中的QS為電源刀開關(guān)，當(dāng)KM1、KM3主觸點(diǎn)閉合時(shí)，電動(dòng)機(jī)星形連接；當(dāng)KM1、KM2主觸點(diǎn)閉合時(shí)，電動(dòng)機(jī)三角形連接。
設(shè)計(jì)一個(gè)三相異步電動(dòng)機(jī)星-三角降壓?jiǎn)?dòng)控制程序，要求合上電源刀開關(guān)，按下啟動(dòng)按鈕SB2后，電機(jī)以星形連接啟動(dòng)，開始轉(zhuǎn)動(dòng)5S后，KM3斷電，星形啟動(dòng)結(jié)束。
若8.4.1項(xiàng)目描述改為：設(shè)計(jì)一個(gè)三相異步電動(dòng)機(jī)星-三角降壓?jiǎn)?dòng)控制程序，要求合上電源刀開關(guān)，按下啟動(dòng)按鈕SB2后，電機(jī)以星形連接啟動(dòng)，開始轉(zhuǎn)動(dòng)5S后，KM3斷電，星形啟動(dòng)結(jié)束。為了有效防止電弧短路，要延時(shí)300ms后，KM2接觸器線圈得電，電動(dòng)機(jī)按照三角形連接轉(zhuǎn)動(dòng)。不考慮過載保護(hù)。
（1） 輸入點(diǎn)和輸出點(diǎn)分配
見表8-3。
表8-3 輸入點(diǎn)和輸出點(diǎn)分配表
（2） PLC接線圖
按照?qǐng)D8-11完成PLC的接線。圖中輸入端的24V電源可以利用PLC提供的直流電源，也可以根據(jù)功率單獨(dú)提供電源。若實(shí)驗(yàn)用PLC的輸入端為繼電器輸入，也可以用220V交流電源。
圖8-11中，電路主接觸器KM和三角形全壓運(yùn)行接觸器的動(dòng)合輔助觸點(diǎn)作為輸入信號(hào)接于PLC的輸入端，便于程序中對(duì)這兩個(gè)接觸器的實(shí)際動(dòng)作進(jìn)行監(jiān)視，通過程序以保證電機(jī)實(shí)際運(yùn)行的安全。PLC輸出端保留星形和三角形接觸器線圈的硬互鎖環(huán)節(jié)，程序中也要另設(shè)軟互鎖。
