Moment of inertia of load on the shaft
The moment of inertia of load (weight of the end effector and workpiece) on the shaft can be set by the “moment of inertia” parameter of the Inertia command.
Enter a value into the [Moment of inertia] text box on the [Weight] panel ([Tools]-[Robot Manager]). (You may also execute the Inertia command from the [Command Window].)
