Product Specifications

Technical details and manufacturing context for Feedback Interface

Definition
A critical component within a 5-Axis CNC Controller that serves as the communication bridge between position/motion sensors (encoders, resolvers, linear scales) and the controller's processing unit. It converts analog or digital feedback signals into usable data for closed-loop control, ensuring precise tool positioning and motion accuracy across all five axes of movement.
Working Principle
Receives electrical signals from position sensors attached to machine axes, conditions these signals (amplification, filtering, noise reduction), converts them to digital format if necessary, and transmits processed position/velocity data to the CNC controller's main processor for real-time motion correction and monitoring.
