Note
Action
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
.
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.
Removing the motor
These procedures describes how to remove the motor.
Preparations before removing the axis-4 motor
Note
Action
Decide which calibration routine to use,
and take actions accordingly prior to begin-
ning the repair procedure.
1
Jog the robot into position:
•
axis 1 = no significance.
•
axis 2 = -65°
•
axis 3 = upper arm pointing straight
up (if possible).
With the robot in this position, there is no
need to drain oil from the axis-4 gearbox
when the motor is replaced.
2
If there is no space to position the upper
arm pointed straight up, drain the axis-4
gearbox.
3
DANGER
Turn off all:
•
electric power supply
•
hydraulic pressure supply
to the robot, before entering the safe-
guarded space.
