5.5.2 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. 5-4 “The Components of the S-Axis
Stopper”.
• DO NOT forget to apply the locktite 242 to the thread part of pin before
inserting it into the stopper.
• Mount the stopper to the S-head with three hexagon head screws M20
(length: 45 mm) and tighten the screws to the tightening torque of 402
N•m (tensile strength: 1200 N/mm
2
or more). The stopper is to be
installed as shown in the Fig. 5-4 “The Components of the S-Axis
Stopper” when the operating range is ±180°.
• The stopper can be installed by every 15 degree pitch, however, to
avoid the mechanical troubles caused by interference between
stoppers (e.g. ±15°, ±165°), install the S-axis mechanical stopper
referring to Table 5-3 "The settable angle for S-Axis Stopper".
• Confirm to stabilize both sides of the protrusion with the hexagon
socket head cap screws as in Fig. 5-5 “Properly-Mounted Image” on
account of the limitation of strength to the unit.
• Refer to the figures: Fig. 5-6(a) to Fig. 5-6(g) as adjusting the setting
angle of the S-Axis mechanical stopper. When mounting the S-Axis
mechanical stopper by inverse angle to the examples in the figures:
Fig. 5-6(a) to Fig. 5-6(g) , settle the machinery symmetrical to those
models.
• As in the figures: Fig. 5-6(a) to Fig. 5-6(g) , the component is reversible
that both sides of the machinery can 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
set the machinery to the stopper based on Fig. 5-4 “The Components
of the S-Axis Stopper”.

NOTE
1. Apply the specified components when mounting the
S-Axis mechanical stopper.
2. TURN OFF the electric power supply before mounting.
