變頻器接線圖
上圖是一副變頻器接線圖。在變頻器的安裝中,有一些問(wèn)題是需要注意的。例如變頻器本身有較強(qiáng)的電磁干擾,會(huì)干擾一些設(shè)備的工作,因此我們可以在變頻器的輸出電纜上加上電纜套。又或變頻器或控制柜內(nèi)的控制線距離動(dòng)力電纜至少100mm等等。以太網(wǎng)采用CSMA/CD(Carrier Sense Multiple Asscess with Collision Detection)介質(zhì)訪問(wèn)控制方式,即載波監(jiān)聽(tīng)多路訪問(wèn)/沖突檢測(cè)方式,該方式可以簡(jiǎn)單通俗地?cái)⑹鰹椤跋嚷?tīng)后講,邊講邊聽(tīng)”。以太網(wǎng)在工廠管理層、車間監(jiān)控層將成為主流技術(shù),與互連網(wǎng)技術(shù)結(jié)合是未來(lái)eManufactory技術(shù)基礎(chǔ); 在沒(méi)有嚴(yán)格時(shí)間要求的設(shè)備層也將獲得一定的發(fā)展;但對(duì)一般工業(yè)網(wǎng)絡(luò)要求實(shí)時(shí)性、確定性通信場(chǎng)合,現(xiàn)場(chǎng)總線技術(shù)還將處于主導(dǎo)地位;我們必須學(xué)會(huì)面對(duì)一個(gè)多種網(wǎng)絡(luò)技術(shù)并存的現(xiàn)實(shí)世界。以下就對(duì)現(xiàn)場(chǎng)總線中的一種 ――令牌總線進(jìn)行研究。
