Note Action
Follow the instructions given in the refer-
ence calibration routine on the FlexPendant
to create reference values. If the robot is to be calibrated with refer-
ence calibration:
Find previous reference values for the axis
or create new reference values. These val-
ues are to be used after the repair proced-
ure is completed, for calibration of the ro-
bot.
Creating new values requires possibility to
move the robot.

routine on page 349 . If no previous reference values exist, and
no new reference values can be created,
then reference calibration is not possible.
