Replacement of Y axis belt (YP330X, YP340X)

1) Turn off the controller power.
2) Remove the robot Y axis cover.
3) Place marks(with a marker etc.) on the pulleys before replacement to limit
deviations in point data occurring due to the belt replacement. (Fig. 5-4)
4) Loosen the tension on the belt and remove the belt.
5) Place the new belt on the pulley lining it up with the marks (for synchroniz-
ing the positions of the two pulleys) you made in step 3) above.
6) Adjust the belt tension and set the origin position again by absolute reset.
(See Chapter 4.)
