Accurate and robust rotor position feedback is very important for precision positioning, fast transient performance and reliability of a servo drive. Typical industrial sensors used are encoders and resolvers. The servo drive position feedback interface connects to a position sensor. Depending on the sensor type, the interface can be analog or digital and needs to be designed for accurate, robust, high-speed and low latency data transmission with high EMC immunity. Often interfaces need to support multiple encoder protocols with a configurable output voltage to mitigate the different types of position feedback sensors. TI reference designs and solutions for servo drive position feedback help solve these system design challenges.
