通过ENDAT接口获取绝对编码器位置.pdf

ENDAT , : TM 383 : A : 2009) ENDAT 刘 琳, 陈建平 ( , 200240) : 利用 DSP 的 SPI接口实现与编码器的通信; 而 ENDAT 接口为数据传输和信号发送提供 了便利通过开机前 取绝对位置值, 工作时读取增量脉冲, 不仅减少了断电干扰, 省去开机 归零, 而且避免了使用大体积码盘, 使得计算读取位置值更加简易, 精确 : 绝对编码器; DSP; 串行通信 Access Absolute Encoder Position Values via ENDAT Interface Based on DSP LIU Lin, CHEN Jian ing ( School ofM echanical Engineering, Shanghai Jiao Tong Un iversity, Shanghai 200240, China) Abstract: U sing DSP, SPI interface commun icate w ith the encoder. ENDAT interface make a great convenience for data and signal transm ission. Access absolute value before o eration and receive u lse at o eration is not only to reduce interference and need not to search the origin, but also avoid the use of a large volume of code d isk, making the calculation and receive of osition valuemore easy and accurate.
