Positioning a Stepper Motor Using Encoder Feedback on an Axis With Non-Linear Mechanics

Learn how to implement closed-loop stepper motor control with encoder feedback to overcome backlash and compliance issues in non-linear mechanical systems. This application note covers tuning parameters including proportional and integral gains (KP, K1, KI, K2), deadband settings, and step-by-step configuration procedures for DMC controllers with internal or external stepper drives. Ideal for applications requiring accurate endpoint positioning despite mechanical imperfections like leadscrew backlash or timing chain compliance.
