Vega 2790504 Resolver to Digital Interface

Works with R25 and other resolvers

  • Works with R11, R25 or most any other Resolver
  • 25 Bit SSI (Synchronous Serial Interface with Fault Status bit)
  • Makes a resolver as easy to use as an encoder
  • Jumper selectable count, 1000, 1024, 2000, 2048, 4000, 4096, 8000, and 8192 A-quad-B with Index and complements
  • Jumper selectable excitation frequency including 2.5, 5.0 and 10 kHz

With the VEGA 2790504 converter you can have both the ruggedness of a resolver and the digital simplicity of the digital interface. The 279050 may be used with almost any resolver. The Index/Marker pulse (Channel Z) will occur once per transducer cycle t the zero degree position..

Vega 2790504 Converter Accuracy and Tracking Rate

  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.
