Renishaw: REF interface for RGH25F/RGH20F Readheads REF-0020-A-05-A

Compatible with REF interfaces

To further boost performance and long-term reliability, the RoHS compliant REF interface replaces the RGB and RGF series, bringing dynamic signal conditioning and resolutions to 0.05 arc seconds.

The RGH20F UHV readhead has been manufactured in dedicated clean conditions, using materials and adhesives specially selected for their low out-gassing rates. The product is then packed and sealed in a vacuum-compliant bag to ensure cleanliness is maintained.

REF interface features Self-tuning active correction The REF interface actively corrects for input signal imperfections to optimise system accuracy. Corrections are made for the following: Automatic Offset Control (AOC) – adjusts offset independently for the sine and cosine signals Automatic Gain Control (AGC) – ensures consistent 1 Vpp signal amplitude Automatic Balance Control (ABC) – adjusts the gain to equalise the sine and cosine signals These correction mechanisms operate over the full working speed range of the readhead. The user can disable/enable the AGC by pressing the CALIBRATE button for greater than 3 seconds. LED indicators The REF interface SETUP LED provides visual feedback of signal strength, error condition and reference mark phasing, for setup and diagnostic use. Flashing Purple indicates high signal alarm condition >135% Purple indicates high signal >110% and 90% and 70% and 50% and 20%
