摘　　要：重点介绍了带距离编码的增量型光栅尺的工作原理,基于该原理开发了用于DELTA液压伺服系统的回参考点程序。丰富了DELTA液压伺服系统回参考点的方法。该方法不必返回一个固定的机械参考点,且正负方向均可实现回零操作,增强了设备的灵活性。The principle of incremental linear measurement with distance-coded reference marks was introduce. It used to Delta hydraulic-servo system that the homing reference program developed based on the principle. It enrich homing reference method of DELTA hydraulic-servo system. By this method, the device does not need to back to the fixed reference every time when homing, and achieves homing by forward direction or reverse direction and it increase the flexibility.

关 键 词：距离编码 伺服系统 回参考点
