5.5 Alterable Operating Range5-6HW04821435.5.2 Notes on the Mechanical Stopper Installation• For S-axis mechanical stopper, install the stopper (drawing No. HW0302424-2) with thepin which is used bottom up (drawing No. HW0402104-1) as in " Fig. 11 The Componentsof the S-Axis Stopper ".• Apply the locktite 242 to screwed parts of the pin when fitting it into the stopper.• Install the stopper to the S head with the hexagon socket head cap screw M20 (length:45mm, 3 screws). Tighten the screws to the tightening torque 402 N m (tensilestrength: 1200 N/mm 2 or more).• The stopper can be installed by every 15 degree pitch, however, to avoid the mechanicaltroubles caused by interference between stoppers (ex. ±15°, ±165°), install the S-axismechanical stopper referring to " Table. 5 Settable Angle for S-Axis Stopper ".• Confirm to stabilize both sides of the protrusion with the hexagon socket head cap screwsas in " Fig. 12 Properly-Mounted Image " on account of the limitation of strength to theunit.• Refer to the figures: “Fig.13” as adjusting the setting angle of the S-axis mechanical stop-per. When installing the S-axis mechanical stopper by inverse angle to the examples inthe figures: “Fig.13”, settle the machinery symmetrical to those models.• As in the figures: “Fig.13”, the component is reversible that both sides of the machinerycan be attached to the stopper, except for the angles of ±30, ±60, ±120, ±150 degrees.Flip side and retry installing the S-axis mechanical stopper if finding any difficulty to setthe machinery to the stopper based on " Fig. 11 The Components of the S-Axis Stopper "..Fig. 12 Properly-Mounted Image• Apply the specified components when installing the S-axis mechanical stopper.• TURN OFF the electric power supply before installation.Hexagon sockethead cap scerwsImproperly-mounted Properly-mountedHexagon sockethead cap scerwsNOTE27/71HW0482143
