描述

IC697PWR724

要避免靜電的沖擊有下列三種方式:在進(jìn)行維修或更換組件時,請先碰觸接地的金屬,以去除身上的靜電;不要碰觸電路板上的接頭或是IC接腳;電子組件不使用時,請用有隔離靜電的包裝物,將組件放置在里面。想象PLC里的元器件是一個嬌嫩的嬰兒,而那些靜電會導(dǎo)致這個嬰兒死亡,你就會更容易以正確的態(tài)度對待這個問題了。
基座安裝(RACK)時,在決定控制箱內(nèi)各種控制組件及線槽位置后,要依照圖紙所示尺寸,標(biāo)定孔位,鉆孔后將固定螺絲旋緊到基座牢固為止。在裝上電源供應(yīng)模塊前,必須同時注意電源線上的接地端有無與金屬機(jī)殼連結(jié),若無則須接上。接地不好的話,會導(dǎo)致一系列的問題,靜電、浪涌、外干擾,等等。由于不接地,往往PLC也能夠工作,因此,不少經(jīng)驗不足的工程師就誤以為接地不那么重要了。這就像登山的時候,沒有系上保護(hù)纜繩一樣,雖然你正常前進(jìn)的時候,保護(hù)纜繩沒有任何作用,但一旦你失足的時候,沒有那根繩子,你的生命就完結(jié)了。PLC的接地,就相當(dāng)于給PLC系上保護(hù)纜繩。
在I/O模塊安裝時,須注意如下事項:I/O模塊插入機(jī)架上的槽位前,要先確認(rèn)模塊是否為自己所預(yù)先設(shè)計的模塊;I/O模塊在插入機(jī)架上的導(dǎo)槽時,務(wù)必插到底,以確保各接觸點是緊密結(jié)合的;模塊固定螺絲務(wù)必鎖緊;接線端子排插入后,其上下螺絲必須旋緊。由于現(xiàn)場的變壓器、電機(jī)等影響,多少會有振動,如果這些螺絲釘松動了,會導(dǎo)致模塊從機(jī)架中松開。

15天包退換 一年質(zhì)保 大量現(xiàn)貨? 國內(nèi)實力庫存商家


選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學(xué)習(xí)編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實數(shù)運(yùn)算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個物理回路驗證,比如變頻器+電機(jī)+測速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會一種至于其它的學(xué)習(xí)起來也就簡單了。
