ADVANCED FEATURES
  • Makes a Synchro/Resolver as Easy to use as an Encoder
  • Non-Phase Locked Loop Design for Faster Loop Closure (Less than 50 uSec @ 10 kHz)
  • Incremental Encoder Output (Absolute within 1 Resolver Cycle)
  • High Resolution and Highly Accurate
  • Tuned Filter For Noise Immunity
  • Single +5 vDC Supply Operation
  • Loss of Signal Detection
  • Fault Signal Outputs: Tri-State A-Quad-B, and Active Pull-Up
  • Status LED's for A, B, Z, Signal HI, Signal MID, and Fault
  • Configurable Fault conditioning for Fail-Safe operations
  • Compact Design and Easy to Install
  • Panel Mount or DIN Rail mounting option
RESOLVER / ENCODER SPECIFICATIONS
  • Works with Harowe/Danaher, Tamagawa, Kerfott, Singer, AMCI, or most any synchro/resolver.
  • Works with R11, R25 and Hollow Shaft Resolvers
  • Two Pole and Multi-Pole (Multi-Speed) Resolvers
  • Transformation ratios from 0.25 to 2.0
  • Jumper selectable excitation frequency 2.5, 5 and 10 kHz
  • Incremental encoder A-Quad-B with Index and complements
  • TTL / Line Driver Outputs for A-Quad-B and Index
  • Jumper selectable quadrature count, 1000, 1024, 2000, 2048, 4000, 4096, 8000, and 8192
  • Index pulse (Z Channel) occurs once per resolver cycle
HIGH SPEED TRACKING

  The tracking rate is a function of the excitation frequency and quadrature counts. With a 2.5 kHz excitation and 4000 quadrature counts the tracking rate would be 9,600 rpm. With a 10.0 kHz excitation and 4000 quadrature counts the tracking rate would be 38,400 rpm. Reducing the counts will increase the tracking rate proportionately.
