RESOLUTE™ absolute optical encoder with Mitsubishi serial communications RA-23M-SA-052B-99-N
Renishaw has proudly announced that its Resolute absolute optical encoder can now be used in linear formats with Mitsubishi serial communication protocol. This enables the optical encoder to be utilized with Mitsubishi’s MELSERVO-J4 line of servo amplifiers, which are commonly used in various industries such as flat panel display (FPD) manufacturing, electronics assembly, factory automation as well as 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 (36 000 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.
