  DRIVE-CLiQ absolute encoder

  Absolute encoders (absolute shaft encoders) are designed on the same scanning principle as incremental encoders, but have a greater number of tracks. For example, if there are 13 tracks, then 2¹³ = 8192 steps are coded in the case of single-turn encoders.
  The code used is a one-step code (gray code), which prevents any scanning errors from occurring.

  After switching on the machine, the position value is transmitted immediately to the controller. There is no need for homing.

  Single-turn encoders

  Single-turn encoders divide one revolution (360 degrees mechanical) into a specific number of steps, e.g. 8192. A unique code word is assigned to each position. After 360 degress the position values are repeated.

  Multi-turn encoders

  Multi-turn encoders also record the number of revolutions, in addition to the absolute position within one revolution. To do this, further code discs which are coupled via gear steps with the encoder shaft are scanned. When evaluating 12 additional tracks, this means that 2¹² = 4096 revolutions can be coded.
