RESOLUTE™ absolute optical encoder with Yaskawa serial communications RA-26Y-RA-052B-30-A

Renishaw's RESOLUTE absolute optical encoder is now compatible with the Yaskawa serial communications protocol in linear and rotary (angle) encoder formats. This allows RESOLUTE to be used with Yaskawa's drives and controllers such as the Sigma 7 range of servo-products. Yaskawa equipment is regularly used in electronics assembly, Flat Panel Display (FPD) manufacturing, factory automation and general motion control applications.

RESOLUTE™ is a true-absolute fine-pitch optical encoder system with excellent metrology performance. Patented RESOLUTE encoder technology combines 1 nm resolution with exceptionally high speed, up to 100 m/s or 14 600 rev/  min, reading from a range of high-accuracy linear tape and spar scales or angle encoder rings. RESOLUTE encoder systems use a single optical absolute track with a nominal pitch of 30 μm, combined with sophisticated optics. This ensures wide set-up tolerances, very low sub-divisional error of ±40 nm and ultra-low noise (jitter) of less than 10 nm RMS, resulting in better velocity control performance and rock solid positional stability. The RESOLUTE system ensures reliability with excellent dirt immunity, built-in separate position-checking algorithm and IP64 sealed readhead with wipe-clean recovery. RESOLUTE encoders are available with a variety of serial protocols. Contact your local Renishaw representative for details.
