Renishaw launches next generation encoder
Renishaw is adding to its extensive optical encoder range with the launch of the VIONiC series, a new family of ultra-high accuracy, super-compact all-in-one digital incremental encoders.
Designed for the world’s most demanding motion control applications, this development brings together Renishaw’s filtering optics with a new custom interpolation and monitoring ASIC that enhances dynamic signal processing and improves signal stability. This achievement has allowed Renishaw to create its highest performance incremental encoder system so far, at the same time combining all necessary interpolation and digital signal processing inside the readhead to eliminate the requirement for additional external interfaces.
The VIONiC range has been designed to reduce overall system size to the minimum achievable for a high-performance system, whilst delivering class-leading performance in terms of cyclic error, jitter and accuracy. Customers can choose between two VIONiC readhead variants. The standard VIONiC readhead features a Sub-Divisional Error (SDE) of better than ±30nm, a range of available resolutions from 5µm to 20nm, and speeds beyond 12 m/s. Alternatively for the most demanding performance requirements, customers can select VIONiCplus with SDE to better than ±10nm, low jitter to 1.6nm RMS and resolutions down to 2.5nm.
