DB-28104 Sinusoidal Encoder Interface Daughter Board

Learn how to interface and configure the DB-28104 daughter board with DMC-21x2/21x3 series motion controllers for high-resolution sinusoidal encoder feedback. This application note covers theory of operation comparing traditional quadrature encoders to sinusoidal encoders, wiring pinouts for all four axes, encoder setup using AF commands with 2^5 to 2^12 interpolation resolution, and system tuning techniques for optimal servo loop performance with nanometer-level precision.
