Max. moment of inertia around the X, Y and Z axes at center of gravity.
Note! The values are for reference only, and should not be used for calculating permitted
load offset (position of center of gravity) within the load diagram, since those also are lim-
ited by main axes torques as well as dynamic loads. Also arm loads will influence the per-
mitted load diagram. For finding the absolute limits of the load diagram, please use the ABB
RobotLoad. Please contact your local ABB organization.
