Compact Photoelectric Encoder Error Automatic Detection System
In order to improve the accuracy and efficiency of compact photoelectric encoder error detection and expand the application of encoder error detection,a error detection system was designed.By analyzing the source of the encoder error,a sys-tem that can automatically detect the encoder dynamic error and static error was built with a stepping motor as the power,a DSP chip as the core of data acquisition and motor drive,and a 21-bit high-precision encoder as the angle reference.And through the analysis and fitting of the error,it realized the error compensation of the encoder and improved the measurement accuracy of the inspected encoder.After actual testing and verification,the designed encoder error detection system meets the design require-ments.
