6 Allowable Load for Wrist Axis and Wrist Flange
6.1 Allowable Wrist Load
The allowable wrist load including the weight of the gripper is 600 kg
maximum. If force is applied to the wrist instead of the load, force on R, B,
and T axes should be within the value as shown in
table 6-1 “Moment and
Total Moment of Inertia” . Contact your YASKAWA representative for
further information or assistance.
When the volume load is small, refer to the moment arm rating shown in
fig. 6-1 “Moment Arm Rating” .
The allowable total moment of inertia is calculated when the moment is at
the maximum. Contact your YASKAWA representative beforehand when
only the moment of inertia is created, or when the load moment is small
while the moment of inertia is large. Also, when the load mass is
combined with an outside force, contact your YASKAWA representative
beforehand.
