5-13. Replacing the Backup Stopper (for EN Type Only)
1) Loosen the BU stopper bracket set screw h with the air turned ON to adjust the crosswise
position of the BU stopper. Loosen the air cylinder set screw f and make the adjustment so
that the height of the BU stopper (rubber part) c is matched with the height of the flange outer
periphery of the ball screw. After that, check that the dimension A shown in the right portion of
Figure 5-8-1 is 5 mm.
2) For the lock sensor position of the BU stopper, loosen the BU lock sensor set screw k, move
the sensor from the cylinder retract status in the B direction. After the sensor has been turned
ON (LED goes off), further move the sensor 1 mm and secure it firmly.
3) To adjust the speed controller, loosen the lock nut of the speed controller j, turn the speed
controller 3 rotations from its fully closed position, and then secure it with the lock nut.
