Reset the Home Position to the User Preference
This procedure will allow the user to hand locate the arms to the desired home posi-
tion and store the new values. This procedure is used in two circumstances: when the
user prefers to establish the HOME position in a location other than the factory set
position and when the robot arms are not exactly aligned after an arm set is replaced.
WARNING
When equipment is energized, live circuits covered, and work per-
formed remotely, the robot is at a Type 2 hazard category. See
