PLC進(jìn)行模擬量控制,要配置有模擬量與數(shù)字量相互轉(zhuǎn)換的A/D、D/A單元。它也是I/O單元,不過是特殊的I/O單元。
變頻器工作原理弄明白之前,不妨先看看變頻器究竟為何方神圣?

但是,這種控制方式在低頻時,由于輸出電壓較低,轉(zhuǎn)矩受定子電阻壓降的影響比較顯著,使輸出最大轉(zhuǎn)矩減小。
輸入掃描在這一階段中,PLC以掃描方式讀入所有輸入端子上的輸入信號,并將輸入信號存入輸入映像區(qū),輸入映像存儲器被刷新。在程序執(zhí)行階段和輸出刷新階段中,輸入映像存儲器與外界隔離,其內(nèi)容保持不變,直至下一個掃描周期的輸入掃描階段,才被重新讀入的輸入信號刷新??梢姡琍LC在執(zhí)行程序和處理數(shù)據(jù)時,不直接使用現(xiàn)場當(dāng)時的輸入信號,而使用本次采樣時輸入到映像區(qū)中的數(shù)據(jù)。如果輸入設(shè)備能使PLC輸入端形成閉合回路,對應(yīng)輸入端編號的內(nèi)部輸入繼電器內(nèi)保存為"1",即相當(dāng)于繼電器線圈導(dǎo)通。在程序執(zhí)行過程中,該編號對應(yīng)的觸點動作;如果輸入設(shè)備能使輸入開路,則對應(yīng)輸入端編號的內(nèi)部輸入繼電器內(nèi)保存為"0",即相當(dāng)于繼電器線圈沒導(dǎo)通,在程序執(zhí)行過程中,該編號對應(yīng)的觸點不動作。如果在PLC處于非輸入掃描的階段,PLC外的輸入設(shè)備狀態(tài)發(fā)生了變化,內(nèi)部輸入繼電器也不會發(fā)生變化,要等到下一個輸入掃描階段才能根據(jù)此時的輸入狀態(tài)來刷新。所以,對于少于十幾毫秒的輸入信號,經(jīng)常采集不到。
