在数控机床中,光电脉冲编码器作为速度和位置检测的元件,故障发生率较高,外在表现多种多样,我们在维修实践中,将有关光电脉冲编码器的故障给予归纳和分类,使故障更加明确。11简介首先对光电脉冲编码器作一下简介。光电脉冲编码器可分为增量式和绝对式。所谓增量式即编码器转过 In CNC machine tools, optical pulse encoder as a component of speed and position detection, a higher incidence of failure, the external manifestations of diverse, we in the maintenance of practice, the photoelectric pulse encoder fault induction to be summarized and classified so that The fault is more clear. 11 Introduction First of all, a brief introduction of optical pulse encoder. Optical pulse encoder can be divided into incremental and absolute. The so-called incremental encoder that turn
