Notes on the Mechanical Stopper Installation
• For S-Axis mechanical stopper, install the stopper (drawing No. HW0302424-2) with the
pin which is used bottom up (drawing No. HW0402104-1) as in " Fig. 11 The Components
of the S-Axis Stopper ".
• DO NOT forget applying the locktite 242 to screwed parts of the pin as inserting it into the
stopper.
• Install the stopper to the S head with the hexagon socket head cap screws M20 (length;
45mm, 3 screws) fastening by the tightening torque intensified 12.9 (Tightening torque:
402 N m).
• To avoid the mechanical troubles, refer to "Table. 5 The Settable Angle for S-Axis Stop-
per" when mounting the S-Axis mechanical stopper. The stopper can be installed by
every 15 degrees.
• Confirm to stabilize both sides of the protrusion with the hexagon socket head cap screws
as in " Fig. 12 Properly-Mounted Image " on account of the limitation of strength to the
unit.
• Refer to the figures: "Fig.13" as adjusting the setting angle of the S-Axis mechanical stop-
per. When mounting the S-Axis mechanical stopper by inverse angle to the examples in
the 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 machinery
can be attached to the stopper, except for the angles of
Flip side and retry installing the S-Axis mechanical stopper if finding any difficulty to set
the machinery to the stopper based on " Fig. 11 The Components of the S-Axis Stopper ".
