style="text-indent:25px">旋轉(zhuǎn)編碼器選型注意事項(xiàng)，旋轉(zhuǎn)編碼器和接近開關(guān)、光電開關(guān)優(yōu)勢比較：編碼器單圈從經(jīng)濟(jì)型8位到高精度17位；編碼器多圈大部分用25位，輸出有SSI，總線Profibus-DP,Can L2,Interbus,DeviceNet。旋轉(zhuǎn)增量式編碼器以轉(zhuǎn)動(dòng)時(shí)輸出脈沖，通過計(jì)數(shù)設(shè)備來知道其位置，當(dāng)編碼器不動(dòng)或停電時(shí)，依靠計(jì)數(shù)設(shè)備的內(nèi)部記憶來記住位置。這樣，通孔編碼器廠家，當(dāng)停電后，通孔編碼器廠家，編碼器不能有任何的移動(dòng)，當(dāng)來電工作時(shí)，通孔編碼器廠家，編碼器輸出脈沖過程中，也不能有干擾而丟失脈沖，不然，計(jì)數(shù)設(shè)備記憶的零點(diǎn)就會(huì)偏移，而且這種偏移的量是無從知道的，只有錯(cuò)誤的生產(chǎn)結(jié)果出現(xiàn)后才能知道。解決的方法是增加參考點(diǎn)，編碼器每經(jīng)過參考點(diǎn)，將參考位置修正進(jìn)計(jì)數(shù)設(shè)備的記憶位置。在參考點(diǎn)以前，是不能保證位置的準(zhǔn)確性的。為此，在工控中就有每次操作先找參考點(diǎn)，開機(jī)找零等方法。編碼器把角位移或直線位移轉(zhuǎn)換成電信號(hào)，前者稱為碼盤，后者稱為碼尺。通孔編碼器廠家</p><div

style="text-indent:25px">串行是指按時(shí)間約定，串行輸出數(shù)字編碼信號(hào)，但也有一些增量編碼器，通過內(nèi)置電池記憶原點(diǎn)，其也可以通過串行輸出位置值，如電池線不聯(lián)，還是增量編碼器，在一些日本伺服系統(tǒng)中較多見。其本質(zhì)其實(shí)還是增量編碼器。編碼器使用某種方式表示并記憶物體的位置，角度和圈數(shù)。即一旦位置，角度和圈數(shù)固定，什么時(shí)候編碼器的示值都固定，包括停電后投電?！霸隽啃途幋a器”做不到這一點(diǎn)。一般“增量型編碼器”輸出兩個(gè)A、B脈沖信號(hào)，和一個(gè)Z(L)零位信號(hào)，A、B脈沖互差90度相位角。通過脈沖計(jì)數(shù)可以知道位置，角度和圈數(shù)增量，通過A,B脈沖信號(hào)超前或滯后可以知道方向，停電后，必須從約定的基準(zhǔn)重新開始計(jì)數(shù)。“增量型編碼器”表示位置，角度和圈數(shù)需要做后處理，重新投電要做“復(fù)零”操作，所以，“增量型編碼器”比“編碼器”在價(jià)格上便宜許多。通孔編碼器廠家那么使用編碼器，尤其是選擇多圈編碼器的意義在哪里呢？</p><div

style="text-indent:25px">增量型編碼器輸出的通常是并行輸出。串行輸出就是通過約定，在時(shí)間上有先后的數(shù)據(jù)輸出，這種約定稱為通訊規(guī)約，其連接的物理形式有RS232、RS422(TTL)、RS485等。串行輸出連接線少，傳輸距離遠(yuǎn)，對(duì)于編碼器的保護(hù)和可靠性就較大提高了，一般高位數(shù)的編碼器都是用串行輸出的。串行輸出編碼器連接的設(shè)備是比較容易的，但是連接非德國系的設(shè)備，接口就是問題了，桁萱自動(dòng)化科技（上海）有限公司提供各種接口輸出的儀表，可以解決這樣的問題。串行：時(shí)間上，數(shù)據(jù)按照約定，有先后；空間上，所有位數(shù)的數(shù)據(jù)都在一組線纜上（先后）發(fā)出。</p><p style="text-indent:25px">編碼器由機(jī)械位置決定的每個(gè)位置，它無需記憶，無需找參考點(diǎn)，而且不用一直計(jì)數(shù)，什么時(shí)候需要知道位置，什么時(shí)候就去讀取它的位置。這樣，編碼器的抗干擾特性、數(shù)據(jù)的可靠性較大提高了。由于編碼器在定位方面明顯地優(yōu)于增量式編碼器，編碼器生產(chǎn)廠家運(yùn)用鐘表齒輪機(jī)械的原理，當(dāng)中心碼盤旋轉(zhuǎn)時(shí)，通過齒輪傳動(dòng)另一組碼盤(或多組齒輪，多組碼盤)，在單圈編碼的基礎(chǔ)上再增加圈數(shù)的編碼，以擴(kuò)大編碼器的測量范圍，這樣的編碼器就稱為多圈編碼器，它同樣是由機(jī)械位置確定編碼，每個(gè)位置編碼不重復(fù)，而無需記憶。編碼器是把角位移或直線位移轉(zhuǎn)換成電信號(hào)的一種裝置。</p><div

style="text-indent:25px">編碼器產(chǎn)生電信號(hào)后由數(shù)控制置CNC、可編程邏輯控制器PLC、控制系統(tǒng)等來處理。這些傳感器主要應(yīng)用在下列方面：機(jī)床、材料加工、電動(dòng)機(jī)反饋系統(tǒng)以及測量和控制設(shè)備。在ELTRA編碼器中角位移的轉(zhuǎn)換采用了光電掃描原理。讀數(shù)系統(tǒng)是基于徑向分度盤的旋轉(zhuǎn)，該分度由交替的透光窗口和不透光窗口構(gòu)成的。此系統(tǒng)全部用一個(gè)紅外光源垂直照射，這樣光就把盤子上的圖像投射到表面上，覆蓋著一層光柵，稱為準(zhǔn)直儀，它具有和光盤相同的窗口。工作是感受光盤轉(zhuǎn)動(dòng)所產(chǎn)生的光變化，然后將光變化轉(zhuǎn)換成相應(yīng)的電變化。單圈編碼器，可以在機(jī)械軸旋轉(zhuǎn)一圈范圍內(nèi)，做到位置信號(hào)輸出的。通孔編碼器廠家</p><p style="text-indent:25px">需要提高分辨率時(shí)，可利用 90 度相位差的 A、B兩路信號(hào)對(duì)原脈沖數(shù)進(jìn)行倍頻，更換高分辨率編碼器。通孔編碼器廠家</p><p style="text-indent:25px">無論使用哪種編碼器做位置反饋，只要出現(xiàn)下列情況都需要對(duì)編碼器進(jìn)行回零操作：編碼器與機(jī)械負(fù)載的傳動(dòng)連接斷開后重新連接；與編碼器連接的上位系統(tǒng)因產(chǎn)品更換、固件更新...等原因記憶丟失；如此看來，在位置測量應(yīng)用中使用機(jī)械式編碼器，將有機(jī)會(huì)極大減少設(shè)備運(yùn)行過程中因系統(tǒng)位置丟失而進(jìn)行回零操作的次數(shù)，因此相對(duì)來講可靠性應(yīng)該算是較高的了。伺服電機(jī)編碼器是安裝在伺服電機(jī)上用來測量磁極位置和伺服電機(jī)轉(zhuǎn)角及轉(zhuǎn)速的一種傳感器，從物理介質(zhì)的不同來分，伺服電機(jī)編碼器可以分為光電編碼器和磁電編碼器，另外旋轉(zhuǎn)變壓器也算一種特殊的伺服編碼器，市場上使用的基本上是光電編碼器，不過磁電編碼器作為后起之秀，有可靠，價(jià)格便宜，抗污染等特點(diǎn)，有趕超的光電編碼器趨勢。通孔編碼器廠家</p></p><br
