對(duì)PLC本體按照規(guī)定的標(biāo)準(zhǔn)和接地條件進(jìn)行接地。此時(shí),應(yīng)避免和變頻器使用共同的接地線,并在接地時(shí)盡可能使二者分開。當(dāng)電源條件不太好時(shí),應(yīng)在PLC的電源模塊以及輸入/輸出模塊的電源線上接入噪聲濾波器和降低噪音用的變壓器等。此外,如有必要在變頻器一側(cè)也應(yīng)采取相應(yīng)措施。
PLC的工作電源有120/230V單相交流電源和24V直流電源。系統(tǒng)的大多數(shù)干擾往往通過電源進(jìn)入PLC,在干擾強(qiáng)或可靠性要求高的場(chǎng)合,動(dòng)力部分、控制部分、PLC自身電源及I/O回路的電源應(yīng)分開配線,用帶屏蔽層的隔離變壓器給PLC供電。隔離變壓器的一次側(cè)最好接380V,這樣可以避免接地電流的干擾。輸入用的外接直流電源最好采用穩(wěn)壓電源,因?yàn)檎鳛V波電源有較大的波紋,容易引起誤動(dòng)作。

其缺點(diǎn)是設(shè)計(jì)出的方案不一定是最佳方案,當(dāng)經(jīng)驗(yàn)不足或考慮不周全時(shí)會(huì)影響線路工作的可靠性。為此,應(yīng)反復(fù)審核電路工作情況,有條件時(shí)還應(yīng)進(jìn)行模擬試驗(yàn),發(fā)現(xiàn)問題及時(shí)修改,直到電路動(dòng)作準(zhǔn)確無誤,滿足生產(chǎn)工藝要求為止。
根據(jù)變頻器發(fā)生故障或損壞的特征,一般可分為兩類;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)說明書上提供的指導(dǎo)方法,進(jìn)行處理和解決。
知道了PLC的工作原理后,理解它的語言就比較容易了。PLC語言最常見的有梯形圖和語句表兩種。其中梯形圖又是最為直觀和好用的。要詳細(xì)了解可以看相關(guān)教材,要強(qiáng)調(diào)的是,雖然原理一樣,基本指令也大同小異,但廠家不同PLC指令符號(hào)會(huì)有所不同,例如,同是上升沿微分,三菱公司的產(chǎn)品用PLS表示,歐姆龍公司卻稱為DIFU,而西門子公司則是│P│。這些具體的區(qū)別就要看各種產(chǎn)品的編程手冊(cè)了

變頻器中也存在一些數(shù)值型(如頻率、電壓等)指令信號(hào)的輸入,可分為數(shù)字輸入和模擬輸入兩種,數(shù)字輸入多采用變頻器面板上的鍵盤操作和串行接口來設(shè)定。模擬輸入則通過接線端子由外部給定,通常是通過0~10V/5V 的電壓信號(hào)或4~20mA的電流信號(hào)輸入。由于接口電路因輸入信號(hào)而異,必須根據(jù)變頻器的輸入阻抗選擇PLC的輸出模塊
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,故又稱聯(lián)鎖觸點(diǎn),一般常開、常閉各兩對(duì)。
