RCU10 Thermal Compensation System

Description

The Renishaw RCU10 offers real time quadrature compensation, overcoming environmental error sources in linear motion systems to improve process accuracy and repeatability. The RCU10 monitors a machine`s ambient environment via a series of sensors and uses advanced digital signal processing to perform real time compensation on the position feedback signals. The unit provides the corrected feedback signals to the motion controller in either RS422 digital A/B or analogue sine / cosine 1 Vpp formats. The RCU10 offers the following features...

  • Refractive index compensation
  • Air pressure and temperature sensors
  • Scale expansion compensation for incremental linear encoders, using material temperature sensors
  • Thermal expansion compensation of machine structure using material temperature sensors
  • Work piece thermal expansion compensation, using material temperature sensors
