亨士樂編碼器德國原裝
一個編碼器的性能一般由分辨率來描述，而非測量精度。編碼器也許可能將運動非常準確地解析至精密位，但每一位的精度受到待測機器的運動質量的影響。比如，如果機器部件在負載下產生變形、或者傳動絲杠上存在0.1 英寸的間隙，在測量時使用一個每圈1000個計數點，輸出精度0.001英寸的編碼器不會消除這0.1 英寸的誤差。編碼器只能用來反映位置，無法提高待測軸運動的基本精度。
注意：對于特定的機械設計，某些運動測量誤差，如絲杠或齒輪系統中的機械間隙和誤差可以通過一些更加*運動控制器進行電子補償。
系統重復精度：重復精度是指受控機器部件重復定位至行程中同一點的誤差。重復精度一般小于系統分辨率，但是比系統精度稍微好些。一個2500個周期、雙通道編碼器能夠產生每轉10000個脈沖。通常在使用Dynapar編碼器時，該信號放大4倍后的精度會優于±1個計數點。

編碼器應用于運動控制領域的參考指南和教程，包括編碼器類型、技術、應用及安裝等。此篇文章介紹編碼器的類型。
編碼器是一種通過響應運動來產生數字信號的傳感器，主要分為兩種類型：響應旋轉運動的旋轉編碼器和響應直線運動的線性編碼器。當與機械傳動裝置，如齒輪齒條、測量輪或主軸配合使用時，軸編碼器也可以用于測量直線運動、速度和位置。編碼器具有多種輸出方式。增量式編碼器在運動時生成一系列脈沖，用于測量速度或被反饋至計數器進行位置跟蹤。而值編碼器則生成多位數字編碼來直接指示當前位置。
編碼器用途廣泛。它們可作為反饋變送器用于電機速度控制、作為傳感器用于測量、切割和定位、作為輸入用于速度速
