NoteAction
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.
Read more about reference calibration for
Axis Calibration in Reference calibration
routine on page 361.If no previous reference values exist, and
no new reference values can be created,
then reference calibration is not possible.
Read more about reference calibration for
Pendulum Calibration in Operating manu-
al - Calibration Pendulum.
If the robot is to be calibrated with fine
calibration:
Remove all external cable packages
(DressPack) and tools from the robot.

Shown in the figure:
• Synchronization marks and syn-
chronization position for axes on
page 353
Jog the robot to calibration position.3
See section
• Replacing the balancing device on
page 278
Remove the balancing device.4
Put two pallets underneath the counter weight
and jog axis 3 so that the counter weight rests
on the pallets.
5
Release the brake of axis 3 so that the
counter weight really rests on the pallets.
6
Jog the lower arm forward to get a better
mounting position in the continued removal
procedure.
