Basic Specifications
5.6 Alterable Operating Range
•
Apply the Locktite 242 to the thread part of the pin HW0407007-1, and
install the pin bottom up into the S-axis mechanical stopper
HW0307574-1 as shown in Fig. 5-8 "Components of S-Axis Stopper".
Mount the stopper to the S-head with three hexagon head screws M20
(length: 70 mm) and tighten the screws to the tightening torque of 402
N•m (tensile strength: 1200 N/mm
as shown in Fig. 5-8 when the operating range is ±180°.
•
The S-axis mechanical stopper can be installed at a pitch of 15
degrees. However, to avoid the mechanical troubles caused by
interference between stoppers (e.g. ±15°, ±165°), install the stopper
referring to Table 5-3 "Settable Angle for S-Axis Stopper".
•
To ensure the stopper strength, make sure to fix both sides of the
protrusion with screws. DO NOT fix only one side of the protrusion.
(See Fig. 5-9 "Properly-Mounted Image".)
•
As in the figures: Fig. 5-10(a) "Properly-Mounted Models for S-Axis
Stopper" to Fig. 5-10(m) "Properly-Mounted Models for S-Axis
Stopper", the S-axis mechanical stopper is reversible that either side of
the stopper can be used and installed except for the installation at the
angles: ±30, ±60, ±120, ±150 degrees. If the stopper cannot be
installed in the range shown in Table 5-3, flip the stopper and retry
installing the stopper.
