增量式
增量式編碼器軸時(shí)，有相應(yīng)的相位輸出。其方向的判別和脈沖數(shù)量的增減，需借助后部的判向電路和計(jì)數(shù)器來(lái)實(shí)現(xiàn)。其計(jì)數(shù)起點(diǎn)可任意設(shè)定，并可實(shí)現(xiàn)多圈的無(wú)限累加
和測(cè)量。還可以把每轉(zhuǎn)發(fā)出一個(gè)脈沖的Z，作為
參考機(jī)械零位。當(dāng)脈沖已固定，而需要分辨率時(shí)，可利用帶90度相位差A(yù)，B的兩路，對(duì)原脈沖數(shù)進(jìn)行倍頻。
正弦波
正弦波編碼器也屬于增量式編碼器，主要的區(qū)別在于輸出是正弦波模擬量，而不是數(shù)字量。它的出現(xiàn)主要是為了電氣領(lǐng)域的需要－用作電動(dòng)機(jī)的反饋檢測(cè)元件。在與其它相比的基礎(chǔ)上，人們需要?jiǎng)討B(tài)特性時(shí)可以采用這種編碼器。.
