REE INTERPOLATORS - Replaced RGE interfacesThe REE digital series of interpolators is designed to accompany the RG2 (20 µm) and RG4 (40 µm) encoder systems by offering a wide range of interpolation factors. Industry standard 1 Vpp differential input analogue signals are interpolated to industry standard RS-422A digital quadrature output signals
These interpolators can be used with any standard 1Vpp differential output encoder system to enable easy integration with industry standard digital controller inputs.
When interfaced with 40 µm pitch systems such as the RGH34, RGH40 and RGH41, the interpolators give resolutions down to 10 nm. When used with 20 µm pitch systems such as the RGH22, RGH24 and RGH20, the interpolators will resolve down to 5 nm. The REE interpolators are fully RoHS compliant and feature user selectable AGC (Auto Gain Control) that is operational at all speeds. These interpolators are capable of operational speeds of over 3 m/s at 100 nm resolution from a 20 µm encoder signal period. The REE interpolators feature a tri-coloured setup LED indicating incremental signal strength. This allows ease of setup for optimum performance. A proportional external setup signal and calibration cycle also help to simplify installation
The REE interpolators have a low cyclic error – less than 50 nm from 20 µm signal period at low speed. This is achieved by active offset, balance and gain control which is operational, when selected, at all speeds.
REE INTERPOLATORS - Replaced RGE interfaces
NOTE: REE interpolators are for use with all industry standard 1 Vpp readheads.
The analogue version of REE is intended to replace the AGC interface (A-9539-0130).
