Renishaw
launches next generation of digital encoder
Renishaw, the
world-leading metrology specialist, 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 renowned filtering optics with a new custom interpolation
and monitoring ASIC (Application-Specific Integrated Circuit) 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 <±30 nm, a range of available resolutions from 5 µm to 20 nm,
and speeds beyond 12 m/s. Alternatively for the most demanding performance
requirements, customers can select VIONiCplus™ with best-in-class
SDE to <±10 nm, low jitter to 1.6 nm RMS and resolutions from 100 nm
down to 2.5 nm. Low SDE encoders are essential to minimise velocity
ripple, which is important in constant-velocity applications such as laser
scanning.
VIONiC series encoders
are available with the same linear and rotary (angle) scale ranges as the
TONiC™ series, such that existing customers may choose to install VIONiC as a
drop-in replacement. Available scale types include metal tape, spar, and rotary
rings (including ultra-high accuracy REXM). All VIONiC scales come with
customer selectable IN-TRAC™
reference marks embedded in the incremental channel and dual-limit switches in
the case of linear scales.
Unrivalled ease of
set-up and calibration is supported by an Advanced Diagnostic Tool (ADT), which
includes user software that allows control and monitoring of VIONiC’s set-up
and calibration routines. New software features include: enhanced graphics, automatically
generated plots of signal strength vs position, Lissajous plots, DRO output,
and readhead pitch indication. This set-up tool is ideal for factory
production-line installation as it allows remote, advanced calibration
features.
The VIONiC family of
incremental encoders has CE approval and is manufactured by Renishaw, using
strict quality controlled processes that are certified to ISO 9001:2008, and,
like all Renishaw encoders, is backed by a truly responsive global sales and
support network. The VIONiC encoder series is available to order from August
2016.
