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。
變頻器工作原理都一直,那世界上那么多變頻器為毛不一樣呢?如果你在這樣吶喊的話,我只能說(shuō),抱歉是的,而且他們還可以這樣分類(lèi)(請(qǐng)自行腦補(bǔ)強(qiáng)迫癥模式的開(kāi)啟過(guò)程):按照主電路工作方式分類(lèi),可以分為電壓型變頻器和電流型變頻器;按照開(kāi)關(guān)方式分類(lèi),可以分為PAM控制變頻器、PWM控制變頻器和高載頻PWM控制變頻器;按照工作原理分類(lèi),可以分為V/f控制變頻器、轉(zhuǎn)差頻率控制變頻器和矢量控制變頻器等;按照用途分類(lèi),可以分為通用變頻器、高性能專(zhuān)用變頻器、高頻變頻器、單相變頻器和三相變頻器等。
觸點(diǎn)系統(tǒng)包括主觸點(diǎn)和輔助觸點(diǎn)。主觸點(diǎn)用于通斷主電路,通常為三對(duì)常開(kāi)觸點(diǎn)。輔助觸點(diǎn)用于控制電路,起電氣聯(lián)鎖作用,故又稱(chēng)聯(lián)鎖觸點(diǎn),一般常開(kāi)、常閉各兩對(duì)。
作為一種工業(yè)控制電子裝置,PLC若不能對(duì)這些量進(jìn)行控制,那是一大不足。為此,各PLC廠家都在這方面進(jìn)行大量的開(kāi)發(fā)。目前,不僅大型、中型機(jī)可以進(jìn)行模擬量控制,就是小型機(jī),也能進(jìn)行這樣的控制。

根據(jù)變頻器發(fā)生故障或損壞的特征,一般可分為兩類(lèi);一種是在運(yùn)行中頻繁出現(xiàn)的自動(dòng)停機(jī)現(xiàn)象,并伴隨著一定的故障顯示代碼,其處理措施可根據(jù)隨機(jī)說(shuō)明書(shū)上提供的指導(dǎo)方法,進(jìn)行處理和解決。
接觸器額定電流是指接觸器在長(zhǎng)期工作下的最大允許電流,持續(xù)時(shí)間≤8h,且安裝于敞開(kāi)的控制板上,如果冷卻條件較差,選用接觸器時(shí),接觸器的額定電流按負(fù)荷額定電流的110%~120%選取。對(duì)于長(zhǎng)時(shí)間工作的電機(jī),由于其氧化膜沒(méi)有機(jī)會(huì)得到清除,使接觸電阻增大,導(dǎo)致觸點(diǎn)發(fā)熱超過(guò)允許溫升。實(shí)際選用時(shí),可將接觸器的額定電流減小30%使用。
硬件部分的模擬調(diào)試主要是對(duì)控制柜或操作臺(tái)的接線進(jìn)行測(cè)試??稍诓僮髋_(tái)的接線端子上模擬PLC外部的開(kāi)關(guān)量輸入信號(hào),或操作按鈕的指令開(kāi)關(guān),觀察對(duì)應(yīng)PLC輸入點(diǎn)的狀態(tài)。
