What it means

Axis not synchronized: one or more relative measurement axes are not synchronized.

What to check

  • Make sure that no program is running.
  • Switch to Motors ON and synchronize all the listed mechanical units.
  • Look for the cause of the loss of synchronization if it recurs (battery, measurement wiring).
  • Note: Direct successor of "509 ERREUR SYNCHRO." on S2/S3 cabinets (the S2/S3 entry already references it).
