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 begin-
ning the repair procedure.
Remove any tool or other equipment fitted
to the robot.
Action
Jog the robot to a position so that the area
where the counterweight is fitted to the
parallel arm, is horizontal to the foundation.
DANGER
Turn off all:
• electric power supply
• hydraulic pressure supply
• air pressure supply
to the robot, before entering the robot
working area.
