[Abstract]:In order to improve the detection accuracy and efficiency of incremental encoder and realize the automatic detection of incremental encoder, an automatic detection system of incremental photoelectric encoder based on FPGA is designed. The system can quickly detect the uniformity and orthogonality error of the detected incremental photoelectric encoder. Firstly, the brushless DC motor is used to drive the detected incremental encoder to rotate at a uniform speed. Secondly, a high-speed data acquisition system is constructed by using FPGA to collect the relevant data of the detected encoder automatically, and the errors of uniformity and orthogonality are calculated. Finally, the test results are displayed by LCD. The experimental results show that the system can accurately detect the incremental encoder error with a resolution of 40 ".
