Absolute – EnDat

Proprietary serial communication protocols for absolute encoder feedback developed by Heidenhain. Transmitted information includes data plus separate Sin/Cos signals.



  • Absolute feedback gives the drive enough information to start sinusoidal commutation without the need for Hall Sensors or "wake-and-shake" routine

ADVANCED Motion Controls' Capabilities

  • 8-Wire interface plus two wires for the optional reference mark
  • 38.4 kbps data rate
  • Interpolation of the 1Vp-p Sin/Cos up to 2048 counts per cycle
