Calculate Rotation Inertia
Rotation inertia is quantity used to indicate a force is against the rotation of an
object. When a fixture/an end effector are installed on the end of ball screw spline,
rotation inertia for the loaded device must be taken into account.
Please calculate if total rotation inertia at the end of ball
screw spline is within rated/maximum permissible inertia.
If rotation inertia is greater than the value, the performance
and lifetime will be reduced.
