QUANTiC™ encoder series

The QUANTiC encoder system integrates Renishaw's filtering optics design and interpolation technology to create a high performance, super-compact, digital all-in-one incremental open optical encoder. QUANTiC encoders are easy to install with exceptionally wide installation and running tolerances, along with built-in installation and calibration functions. More detailed diagnostic information can be accessed by using the Advanced Diagnostic Tool ADTi‑100 and ADT View software during installation or for in-field diagnostics and fault finding.

In-built reliability and ease of installation

Robust position measurement over contamination  

QUANTiC readheads ensure excellent motion control performance in a wide range of applications by minimising positional error over scale contamination. A new detector design provides an additional layer of signal filtering which helps to eliminate non-harmonic signal frequencies, ensuring low Sub-Divisional Error (SDE) and minimal signal variation over dirt or contamination on the scale.

Increased operating tolerances whilst maintaining metrology

The new detector design helps to increase installation and operational tolerances, whilst maintaining metrological performance through the reduction of phase error due to fringe fanning. Combining this with Renishaw's established filtering optics and signal processing technology makes QUANTiC a robust and easy to use incremental encoder.

Advanced Diagnostic Tool

The QUANTiC 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 optimisation over the entire axis length
  • Readhead pitch indication
  • Limit and reference mark indication
  • Digital readout of encoder position (relative to the scale)
  • Monitoring the velocity against time graph
  • Exporting and saving data
