This encoder series offers an incremental encoder augmented by IO-Link configurability and diagnostics capabilities. There are two different implementations:

  • Incremental encoder and IO-link on a dedicated wire (RGZ electronics)
  • Incremental encoder with IO-link multiplexed on Z wire, in this case when working in a mode, the other one is disabled (RGY electronics)

IO-LINK features

Process data

  • Position: single turn 16 bits max
  • Speed: calculated speed in rpm (signed)

Programmable Parameters

Direction: clockwise or counter-clockwise, changes counting direction and speed sign.

Reset/Preset value: The position process data is set to the preset parameter. The preset parameter shall be a valid position value according to the resolution chosen. Zero position shall be set using this parameter. This command affects the incremental zero pulse position.

For incremental mode :

  • Incremental resolution: number of cycles per turn: from 1 to 10000 • Output voltage level: HTL or TTL
  • Zero pulse width: 90°, 180° 270° or 360° Absolute parameters (in IO-Link mode) :
  • Resolution per turn: 1 to 16 bits • Speed window calculation: time between each speed data update.


  • Operating Hours: number of hours since factory reset
  • Temperature: event triggers when the temperature exceeds specifications
