Encoder Selection Guide
Derive minimum encoder resolution from your repeatability, step size, velocity, and servo rate requirements. Compare real encoder products from Heidenhain, Renishaw, Attocube, PI, and Celera with scored fit rankings and thermal stability analysis.
Application Requirements
Target 3-sigma bidirectional repeatability.
Smallest commanded step the encoder must resolve.
Position noise budget for the encoder contribution.
From the motion controller.
