A Compensation Run

Compensation value routine for angle encoder with AWE 1024 evaluation electronics (provided by Martin v. Zimmermann):

• Enter encoder menu: ONLINE$>$ gpib/awe 1
• Check the status of the encoder, enter awe command: a0x. The status should be 11002, with
  1. 0/1 compensation no/yes
  2. 0/1 reference signal no/yes
  3. see Heidenhein manual
  4. see Heidenhein manual
  5. see Heidenhein manual

• If the encoder has no reference signal, move across the reference mark located at 0 on the hardware scale:
  • Enter awe command: r1x
  • Perform a full turn of the goniometer

• If the encoder has no compensation, perform the compensation routine
  • Enter awe command: c1x
  • Ignore error messages
  • poll byte c0: start rotating forward (clockwise), two times across the reference mark, the rotation velocity needs to be between 2.5 and 5.8 turns/min use an electric drill together with a belt to assure the right rotation velocity.

  • poll byte c1: start rotating backwards, two times across the reference mark
  • poll byte c2: compensation run finished
  • poll byte c3: rotation speed out of range

• Set the encoder to zero: enter awe command: c2
