Interfacing Design of an AC Servomotor Encoder

摘要

A CPLD-bafied interface design of an AC servomotor encoder is presenfied. The interfacecircuit of an integrafied rotary encoder is first desigfied, which includes the communication protocolsof Manchester coding find the cyclic fiedfindancy check (CRC). A set of three linear phase finiteimpulse response (FIR) ffilters is then implemenfied to prevent noise from corrupting the output signalsof servomotor encoders. The experimental results of the correspfinding setup illustrate theeffectiveness of the interface design.
