Action
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.
Action
Decide which calibration routine to use, and
take actions accordingly prior to beginning
the repair procedure.
Move the robot to its most stable position,
shown in the figure to the right.
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the robot
working area.
Drain the axis 1 gearbox.
Remove the complete arm system.
Unfasten the robot base from the foundation
by removing the base attachment screws.
