意大利ELTRA意爾創(chuàng)編碼器*
軸或軸孔與驅(qū)動的伺服電機(jī)同軸連接（也有與絲杠同軸連接的，是分離型編碼器），電機(jī)或機(jī)械部分旋轉(zhuǎn)時帶著編碼器軸同步旋轉(zhuǎn)，編碼器就可以給出幾個均勻的脈沖串序列-----A、B、A-、B- 等電氣信號，而且轉(zhuǎn)一圈給出的各個脈沖串的脈沖總數(shù)是固定的數(shù)n。這樣，一個脈沖對應(yīng)著軸轉(zhuǎn)動了360/n度的機(jī)械角位移，只要計數(shù)相關(guān)的脈沖個數(shù)，就可以實現(xiàn)角位移的測量。脈沖串可以有2列----A列和B列，還可以在加上他們各自的反相脈沖串序列。除此之外，還有Z脈沖------每轉(zhuǎn)一圈，在某個確定的位置，給出一個Z脈沖，此Z脈沖可以看做就是剛剛轉(zhuǎn)過的那一圈的標(biāo)志。
和PLC結(jié)合使用時隨便取A,B,Z中的一相都可以-----只取Z相是不行的。只取A、B，或者都取是可以的，把他們輸入到plc的高速計數(shù)器接口內(nèi)即可對脈沖計數(shù)，就是相當(dāng)于對角位移測量反饋了。Z相是有特殊用途的，但不是單獨用于反饋計數(shù)的
