Linear Encoder (Electronic Linear Scale) for CNC and DRO: A Practical Guide
Author: Nima Rad Short answer: A linear encoder, also called an electronic linear scale, measures the real straight-line position of a machine axis and turns it into an electrical signal. It feeds a digital readout (DRO) for manual machines or gives a CNC controller direct position feedback for closed-loop control, so errors from backlash, screw […]
Incremental Encoders in CNC: Working Principle, Signals, Types and Applications
Written by: Radonix R&D Team Short answer: An incremental encoder converts shaft rotation into a stream of pulses. Two channels, A and B, are offset by 90° so the controller can tell direction and count position changes, while a Z (index) pulse marks one reference point per revolution for homing. It reports movement relative to […]
