Spare part
no.
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.
Action
Decide which calibration routine to use, and
take actions accordingly prior to beginning the
repair procedure.
DANGER
Turn off all:
• electric power supply to the robot
• hydraulic pressure supply to the robot
• air pressure supply to the robot
Before entering the robot working area.
