Renishaw:RESOLUTE™ absolute optical encoder with Siemens DRIVE-CLiQ serial communications RA-29D-AA-052B-30-S
New from Renishaw are RESOLUTE true-absolute linear and rotary (angle) encoders with new compatibility for Siemens DRIVE-CLiQ - the innovative, powerful communications interface to connect encoder and direct measurement systems with SINUMERIK and SINAMICS drive components. Allowing machine builders to achieve higher performance and greater reliability, this product conforms to Category 2 in accordance with EN 13849 and so is suitable for use in safety-related axes such as linear motors and direct drive rotary (DDR) torque motors.

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.
