西門(mén)子200 smartPLC,帶V90伺服，配增量式編碼器；系統上電以后進(jìn)行回零，回零方式采用編碼器Z相回零，沒(méi)有參考接近開(kāi)關(guān)。
然后伺服開(kāi)始運動(dòng)，運動(dòng)形式為：
1.0.5內加速走位置10CM/走角度580度。
2.運動(dòng)到0點(diǎn)。（但不會(huì )再執行回零操作)
如此反復N次以后，這個(gè)反復定位精度能保證嗎？ （第一次 回0的位置和第N次回零的位置是一個(gè)位置嗎？有誤差嗎）（第一次走到10CM的位置和第N次走10CM的位置是同一個(gè)位置嗎？ 有誤差嗎？）
增量式編碼器的累計誤差是什么？ 上面這種應用是不是就會(huì )產(chǎn)生累計誤差？
