    • Performance
      Max. resolution (number of steps per revolution x number of revolutions)18 bit x 12 bit (262,144 x 4,096)
      Error limits G0.03° 1)
      Repeatability standard deviation σr0.002° 2)
      • 1) In accordance with DIN ISO 1319-1, position of the upper and lower error limit depends on the installation situation, specified value refers to a symmetrical position, i.e. deviation in upper and lower direction is the same.
      • 2) In accordance with DIN ISO 55350-13; 68.3% of the measured values are inside the specified area.
