近幾年來，可編程序控制器(PLC)以其可靠性高、適應(yīng)性強、靈活性好、編程簡單、容易掌握等特性，在各個領(lǐng)域發(fā)揮越來越重要的作用。在PLC控制系統(tǒng)中，PLC作為主要控制設(shè)備，必然與控制對象中各種輸入信號(如按鈕、限位開關(guān)、拔動開關(guān)、繼電器的觸點及其它檢測信號等)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/輸出單元或更換點數(shù)更多的PLC來解決有時又不合算，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/輸出點數(shù)，相當(dāng)于擴(kuò)展了PLC的I/O點數(shù)。本文從硬件、軟件兩個方面介紹在不增加硬件情況下"擴(kuò)展"PLC I/O點數(shù)的幾種方法。
另外，其機(jī)械特性終究沒有直流電動機(jī)硬，動態(tài)轉(zhuǎn)矩能力和靜態(tài)調(diào)速性能都還不盡如人意，且系統(tǒng)性能不高、控制曲線會隨負(fù)載的變化而變化，轉(zhuǎn)矩響應(yīng)慢、電機(jī)轉(zhuǎn)矩利用率不高，低速時因定子電阻和逆變器死區(qū)效應(yīng)的存在而性能下降，穩(wěn)定性變差等。因此人們又研究出矢量控制變頻調(diào)速。
指示作用利用低壓電器的控制、保護(hù)等功能，檢測出設(shè)備運行狀況與電氣電路工作情況，如絕緣監(jiān)測、保護(hù)掉牌指示等。
