Controlling the electromotor is an important part of modern industry control system.As a detection equipment on the angle-displacement of a electromotor,the encoder provides an important feedback to the system.Here,a processing universal module of Hei-denhain photoelectric encoders based on FPGA and DSP is introduced,which is applied to embedded system and can detect and process signals of Heidenhain's both high-precision incremental encoder and absolute encoder with EnDat2.2 bidirectional digital interface.After simple operation by users,the module can apply to encoders of different types and different precision.This module passed experiments, debugs and tests,proved to be effective for working,having been used in the laboratorial field.
