RENISHAW: VIONiC PLUS ENCODER SYSTEM READHEAD S2BBQ30D50B
Renishaw: VIONiC™ PLUS readheads

VIONiCplus™ is Renishaw's new highest performance optical incremental encoder system that has been launched as part of the VIONiC™ digital all-in-one encoder series. The VIONiC design combines all necessary interpolation and signal processing inside the readhead and eliminates the requirement for additional external interfaces. To this end, Renishaw developed a new Versatile Interpolation ASIC (VIA) chip to perform all of the functions originally executed by the interface. Other features, working in conjunction with the Advanced Diagnostic Tool (ADT), bring the end-user wide-ranging monitoring and diagnostic feedback.

The VIONiCplus incremental encoder is the culmination of research into the latest fine compensation architectures and advances in modern optimisation algorithms leading to unparalleled heights of performance. By leveraging advances in digital interpolation and signal processing techniques, Renishaw has built an encoder which can achieve Sub-Divisional Error (SDE) as low as ±10 nm – unprecedented from a 20 µm-pitch scale. VIONiCplus is the first conventional optical encoder to deliver the performance advantages of ultra-fine pitch (<4 µm) systems with the additional benefits of better yaw and rideheight tolerance, easier installation, smaller system size, higher speeds, more flexible scale options including longer lengths, better dirt immunity and lower cost.
