L-9517-9399-01-DRESA is a one-piece stain l ess steel ring with a single track, true absolute scale marked di r ect l y onto the periphery.Read by Renishaw’s revolutionary new absolute fi ne pitch encoder sys t em,, it has high tol e r a nce to dirt,scratch e s and greasy fi n g erprints that can cause other en c od e r sys t ems to mis c ount.The RESA offers impressive accuracy with resolution to 0.00030 arc second, suiting the most demanding precision applications. The low profi le RESA, with large internal di a m e t er, is easy to design into most in s tal l a t ions. Equally important, its low mass, low inertia design does not compromise system per f or m ance. RESA is available in a wide range of sizes and line counts, providing compatibility with industry standard controllers.System features• Compatible with the revolutionary newtrue absolute encoder, • Angular resolution to 0.00030 arc second • System repeatability to 0.0075 arc second • 36 000 rev/min maximum speed for all resolutions • Patented taper mount sim p li fi es integration and minimises installation errors • Large internal diameter for ease of integration • Available in sizes from Ø52 mm to Ø550 mm• Custom sizes also available • Low mass and low inertia • Ultra-low inertia versions also available• Integral set-up LED on readhead for quick set-up and instant ‘health check’ at any time• 30 µm scale pitch ensures exceptional motion control performance• Resolutions to 27 bit with FANUC or 32 bit with BiSS± 0.2°NOTE: θ is the angle between one tapped hole and the adjacent clearance hole.
