描述

140CPU53414A

在數(shù)控機床出現(xiàn)以前,順序控制技術(shù)在工業(yè)生產(chǎn)中已經(jīng)得到廣泛應(yīng)用。許多機械設(shè)備的工作過程都需要遵循一定的步驟或順序。順序控制即是以機械設(shè)備的運行狀態(tài)和時間為依據(jù),使其按預(yù)先規(guī)定好的動作次序順序地進行工作的一種控制方式。
數(shù)控機床所用的順序控制裝置(或系統(tǒng))主要有兩種,一種是傳統(tǒng)的“繼電器邏輯電路”,簡稱RLC(RelayLogicCircuit)。另一種是“可編程序控制器”,即PLC。
RLC是將繼電器、接觸器、按鈕、開關(guān)等機電式控制器件用導(dǎo)線連接而成的以實現(xiàn)規(guī)定的順序控制功能的電路。在實際應(yīng)用中,RLC存在一些難以克服的缺點。如:只能解決開關(guān)量的簡單邏輯運算,以及定時、計數(shù)等有限幾種功能控制,難以實現(xiàn)復(fù)雜的邏輯運算、算術(shù)運算、數(shù)據(jù)處理,以及數(shù)控機床所需要的許多特殊控制功能,修改控制邏輯需要增減控制元器件和重新布線,安裝和調(diào)整周期長,工作量大;繼電器、接觸器等器件體積較大,每個器件工作觸點有限。當(dāng)機床受控對象較多,或控制動作順序較復(fù)雜時,需要采用大量的器件,因而整個RLC體積龐大,功耗高,可靠性差等。由于RLC存在上述缺點,因此只能用于一般的工業(yè)設(shè)備和數(shù)控車床、數(shù)控鉆床、數(shù)控鏜床等控制邏輯較為簡單的數(shù)控機床。

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、進而練習(xí)整數(shù)運算、實數(shù)運算、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+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。
