Absolute – BiSS-C

Open serial communication protocol for absolute encoder feedback developed by IC-Haus. BiSS stands for Bi-directional Synchronous Serial Interface. The signal is “data only”, meaning there is no extra Sin/Cos signal for the drive to process.



  • Absolute feedback gives the drive enough information to start sinusoidal commutation without the need for Hall Sensors or "wake-and-shake" routine
  • Encoder position data is polled by the drive at a rate that is synchronous with the position loop

ADVANCED Motion Controls' Capabilities

  • 4-Wire interface
  • 10 MHz data clock
