General Technology

1. What are optical encoders? 2. How is the encoder output frequency specified? 3. What solvent should be used to clean scales? 4. Is it possible to remove an adhesive-backed tape scale and then reuse it? 5. What adhesive should be used to mount a scale on a hub? 6. What is the difference between Magnetic vs. Inductive vs. Optical Encoders technology? 7. How is resolution determined for an application if the customer does not know the performance requirements? 8. What is MMA and how does it work? 9. How does resolution, accuracy and repeatability effect position feedback in a control system? 10. What is meant by the Celera Motion specific term “Megastate”? 11. How does scale eccentricity or bearing runout affect angular error?

Product Specific

1. If the Aura absolute optical encoder is within alignment tolerances, is calibration necessary for the published accuracy specification? 2. How do I know if the Aura absolute optical encoder is within alignment tolerances? 3. Can the Aura absolute encoder tolerate fingerprints on the scale? 4. For the Optira encoder, why does the analog version not need calibration, whereas the digital version requires a calibration step?
