L-9517-9678-03-A VIONiC series encoder system The VIONiC encoder series is Renishaw s highest performing incremental optical encoder.

The VIONiC readhead integrates Renishaw s market proven filtering optics and advanced interpolation technology.

Designed with intuitive auto calibration mode, VIONiC is easy to install.

VIONiC reads a wide range of linear and rotary scales, from low expansion ZeroMet, to high accuracy REXM Rings.

1 L A VIONiC series encoder system The VIONiC encoder series is Renishaw s highest performing incremental optical encoder. It provides digital position feedback with superior metrology, high speeds and high reliability. The VIONiC readhead integrates Renishaw s market proven filtering optics and advanced interpolation technology. This provides excellent dirt immunity, ultra-low Sub-Divisional Error (SDE), and the benefit of eliminating the need for additional adaptors or separate interfaces. Designed with intuitive auto calibration mode, VIONiC is easy to install. In addition, an optional Advanced Diagnostic Tool ADTi provides comprehensive real-time encoder feedback during installation and diagnostics. VIONiC reads a wide range of linear and rotary scales, from low expansion ZeroMet, to high accuracy REXM Rings. This makes it a versatile product suitable for a wide variety of applications, where metrology cannot be compromised. Compact, all-in-one, digital output, optical encoder Dynamic signal processing provides ultra low Sub Divisional Error of typically <±15 nm Compatible with linear and rotary scales with IN-TRAC auto-phase optical reference mark (datum) Auto Gain Control, Auto Balance Control and Auto Offset Control ensure consistent signal strength for long-term reliability Integrated set-up LED for ease of installation Maximum speed to 12 m/s (3.63 m/s at 0.1 µm resolution) Digital signals direct from the readhead: Resolutions from 5 μm to 2.5 nm Integrated dual limits (linear only) Filtering optics optimised for excellent dirt immunity Optional Advanced Diagnostic Tool ADTi-100 to optimise set-up and assist with system diagnostics

System Features Need superior motion control? VIONiC implements our latest interpolation algorithms and signal processing techniques to achieve a Sub-Divisional Error as low as <±15 nm.

2 System Features Need superior motion control? VIONiC implements our latest interpolation algorithms and signal processing techniques to achieve a Sub-Divisional Error as low as <±15 nm. Low SDE directly equates to low velocity ripple which is important for constant velocity applications, such as scanning measurement systems. VIONiC s intelligent interpolation chip can achieve 8000 x interpolation which equates to 2.5 nm resolution directly out of the readhead. This system is used when precision and repeatability is of paramount importance. System type Linear Rotary >135 mm Rotary 135 mm SDE <±15 nm* <±15 nm* <±20 nm * <±10 nm SDE can be achievewd with optimised setup. Please contact your local Renishaw representative for further details. Typical SDE graph for VIONiC linear readheads Error (nm) Interpolated error 10 encoder cycles Readhead position Need higher speed? At its highest clock rate (50 MHz counter speed) the VIONiC readhead outputs quadrature edges with a minimum separation of 25.3 ns to allow this maximum possible speed at fine resolutions. Need higher accuracy? VIONiC readheads are compatible with a range of linear and rotary scales,from ±1 μm/m low expansion linear spar scales to ±1 arc second total installed accuracy rings. Optional Advanced Diagnostic Tool ADTi-100 The VIONiC encoder system is compatible with the Advanced Diagnostic Tool ADTi-100 and ADT View software. They provide comprehensive real-time encoder data feedback to aid more challenging installations and diagnostics. The intuitive software interface can be used for: Remote calibration Signal optimization over the entire axis length Readhead pitch indication Limit and reference mark indication Digital readout of encoder position (relative to scale) Monitoring velocity Exporting and saving data 2
