SRVO-033: Robot not calibrated

A quick-master reference point was being set, but calibration hasn't been completed for the group - the prerequisite step is missing, so the reference can't be recorded.

What it means

A quick-master reference point was being set, but calibration hasn't been completed for the group - the prerequisite step is missing, so the reference can't be recorded.

Common causes

Ranked by what technicians most often find, most likely first.

  1. Calibration not yet executed after power-up or after a mastering-related event.

How to fix it

  1. Run CALIBRATION from SYSTEM > Master/Cal, then set the quick-master reference.
  2. If the Master/Cal screen isn't visible, it needs to be enabled from the variables/menu setup - it's hidden by default on production controllers.
