PLC與繼電器控制邏輯的性能和價格進行相比較:控制邏輯:繼電器控制邏輯采用硬接線邏輯,利用繼電器機械觸點的串聯(lián)或并聯(lián)及延時繼電器的滯后動作等組合成控制邏輯,其連線多而復(fù)雜,體積大,功耗大,一旦系統(tǒng)構(gòu)成后,想再改變或增加功能都很困難。另外繼電器觸點數(shù)目有限,每只一般只有4~8對觸點,因此靈活性和擴展性都很差。而PLC采用存儲邏輯,其控制邏輯以程序方式存儲在內(nèi)存中,要改變控制邏輯,只需改變程序,故稱為"軟接線",其連線少,體積小,加之PLC中每只軟繼電器的觸點數(shù)理論上無限制,因此靈活性和擴展性都很好。PLC由中大規(guī)模集成電路組成,功耗小。
如我廠鋁電解車間環(huán)境惡劣,高粉塵、高溫(夏季廠房上部氣溫高達56℃)、高氧化鋁粉塵、氟化氫腐蝕氣體使多功能天車上變頻器內(nèi)電路板易積塵、風(fēng)扇粘死、電子器件老化迅速、GTR(或IGBT模塊過熱燒壞,故經(jīng)常出現(xiàn)過熱保護,特別是在夏季,這種現(xiàn)象更加頻繁,而且模塊燒壞率很高,即使進口機型(如Siemens、senken、fuji等)情況也是如此。為解決這個問題,我們通過加大天車上使用變頻器容量,才初步降低了變頻器的故障率和報廢率,但效果并不理想。
變頻器的SVPWM控制方式是以三相波形整體生成效果為前提,以逼近電機氣隙的理想圓形旋轉(zhuǎn)磁場軌跡為目的,一次生成三相調(diào)制波形,以內(nèi)切多邊形逼近圓的方式進行控制的。經(jīng)實踐使用后又有所改進,即引入頻率補償,能消除速度控制的誤差;通過反饋估算磁鏈幅值,消除低速時定子電阻的影響;將輸出電壓、電流閉環(huán),以提高動態(tài)的精度和穩(wěn)定度。
對于簡單故障可根據(jù)程序通過PLC的狀態(tài)顯示信息,監(jiān)視相關(guān)輸人、輸出及標(biāo)志位的狀態(tài),跟蹤程序的運行,而復(fù)雜的故障必須使用編程器來跟蹤程序的運行。如某水泵不工作,檢查發(fā)現(xiàn)對應(yīng)的PLC輸出端口為0,于是通過查看程序發(fā)現(xiàn)熱水泵還受到水溫的控制,水溫不夠PLC就沒有輸出,把水溫升高后故障排除。

大多數(shù)模塊式PLC使用底板或機架,其作用是:電氣上,實現(xiàn)各模塊間的聯(lián)系,使CPU能訪問底板上的所有模塊,機械上,實現(xiàn)各模塊間的連接,使各模塊構(gòu)成一個整體。
協(xié)議的設(shè)置可以從預(yù)先準(zhǔn)備好的通信協(xié)議庫中選擇,或任意創(chuàng)建及編輯。
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,抱歉是的,而且他們還可以這樣分類(請自行腦補強迫癥模式的開啟過程):按照主電路工作方式分類,可以分為電壓型變頻器和電流型變頻器;按照開關(guān)方式分類,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,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,可以分為通用變頻器、高性能專用變頻器、高頻變頻器、單相變頻器和三相變頻器等。
