style="text-indent:25px">讀數(shù)系統(tǒng)全部用一個紅外光源垂直照射，這樣光就把盤子上的圖像投射到接收工具表面上，該接收工具覆蓋著一層光柵，稱為準(zhǔn)直儀，它具有和光盤相同的窗口。接收工具的工作是感受光盤轉(zhuǎn)動所產(chǎn)生的光變化，然后將光變化轉(zhuǎn)換成相應(yīng)的電變化。一般地，旋轉(zhuǎn)高精度角度編碼器也能得到一個速度信號，這個信號要反饋給變頻器，從而調(diào)節(jié)變頻器的輸出數(shù)據(jù)。故障現(xiàn)象：1.旋轉(zhuǎn)高精度角度編碼器壞（無輸出）時，變頻器不能正常工作，變得運(yùn)行速度很慢，而且一會兒變頻器保護(hù)，顯示“PG斷開”聯(lián)合動作才能起作用。</p><p style="text-indent:25px">高精度角度編碼器的外殼封裝：經(jīng)濟(jì)級的外殼封裝依賴于三個螺絲固定（在編碼器的外殼外徑上如有三個螺絲固定，由于螺絲的頂入，而造成外圓輕微變形而不圓，會影響密封性能），而工業(yè)級的外殼沒有螺絲固定，密封是擠壓式+O型密封圈一次密封的。有些用戶以為工作環(huán)境沒有塵、水汽的問題，怎么還會損壞呢？其實(shí)編碼器在使用中，必然有開機(jī)與停機(jī)的變化中，由于熱脹冷縮的溫差而造成內(nèi)外氣壓差，防護(hù)等級差的編碼器，會產(chǎn)生“呼吸性”水汽，由于壓差水汽吸入編碼器，因時間的積累而損壞光學(xué)組件和電氣線路，影響使用或損壞編碼器，較典型的是用一段時間不準(zhǔn)或信號不穩(wěn)定。而有些編碼器在較高溫度下使用出現(xiàn)問題，以為是溫度問題，實(shí)際卻是密封性問題。高精度角度編碼器的優(yōu)點(diǎn)：體積小，精密，本身分辨度可以很高。</p><div

style="text-indent:25px">高精度角度編碼器的主要特點(diǎn)是：測量系統(tǒng)精度高，達(dá)到同類產(chǎn)品國際先進(jìn)水平，由于需要借助用戶軸系的軸承結(jié)構(gòu)來進(jìn)行測量，對被測軸系軸向徑跳和安裝基面的垂直度有較高要求才能保證測量精度；安裝簡單，借助聯(lián)軸脹套可實(shí)現(xiàn)快速高精度同心安裝；尺寸小，適用于安裝空間有限的地方;空心軸比較大直徑可達(dá)80 mm，便于穿電源線、信號線及液壓油管等;沒有軸承，有利于降低成本。高精度角度編碼器測量基準(zhǔn)是精密周期刻線光柵。精密光柵制造采用多種光刻工藝，在石英玻璃上鍍硬鉻線，刻線均勻、邊緣清晰。由于采用光電掃描法，這些刻線是輸出高質(zhì)量信號的關(guān)鍵。玻璃光柵主要用于編碼器轉(zhuǎn)速1500rpm以內(nèi)的應(yīng)用。高精度角度編碼器上的A、B、Z是什么意思？正負(fù)0.01度絕對值編碼器生產(chǎn)廠</p><p style="text-indent:25px">高精度角度編碼器是如何接線的呢！遼寧21位高精度編碼器</p><p style="text-indent:25px">高精度角度編碼器的優(yōu)點(diǎn)：高精度角度編碼器模塊是一個軸承與編碼器的組合件。已完成必要組裝與調(diào)試。也就是說角度編碼器模塊已有確定的性能特性并已測試到符合客戶的技術(shù)要求。簡化機(jī)械連接避免所有敏感的安裝操作。不僅安裝非常容易，而且還能確保在實(shí)際應(yīng)用中達(dá)到要求的精度。各零件間的繁雜匹配和按照機(jī)床環(huán)境要求的調(diào)試都不再必須，也不需要耗時的測試。應(yīng)用領(lǐng)域：高精度角度編碼器模塊設(shè)計用于中低轉(zhuǎn)速的轉(zhuǎn)動軸和中等負(fù)載、高至超高軸承精度以及比較高重復(fù)精度的應(yīng)用。它們能滿足計量應(yīng)用的特殊要求。因此，典型應(yīng)用包括計量技術(shù)的激光追蹤儀、測量機(jī)的高精度回轉(zhuǎn)工作臺及電子工業(yè)的圓晶運(yùn)送機(jī)。也能用于負(fù)載不大的機(jī)床，例如電火花機(jī)床或微型精密機(jī)床。遼寧21位高精度編碼器</p></p><br
