RCU10 Thermal Compensation System


The RCU10 real time quadrature compensation system overcomes 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 AquadB or analogue sine / cosine 1 Vpp formats. The RCU10 can provide: • Refractive index compensation for Renishaw laser encoders, using 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.
