• Allowable Moment of Inertia
The maximum inertial moment of the work that can be carried in rotating motion using the actuator
will vary depending on the rotational speed. Design the work after checking the operating condition
and inertial moment.

Caution: When the rotational axis is used horizontally, load torque will generate due to gravity if
the center of gravity of the work is located away from the center of rotation. In this case,
the rotational speed must be lowered or the inertial moment of the work must be
reduced.
