Action
Decide which calibration routine to use for
calibrating the robot.
• Reference calibration. External cable
packages (DressPack) and tools can
stay fitted on the robot.
• Fine calibration. All external cable
packages (DressPack) and tools
must be removed from the robot.
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.
If no previous reference values exist, and
no new reference values can be created,
then reference calibration is not possible.
If the robot is to be calibrated with fine
calibration:
Remove all external cable packages
(DressPack) and tools from the robot.
