The moment of inertia is defined as "the ratio of the torque applied to a rigid body and its
resistance to motion".

■ The moment of inertia of the load (weight of the end effector and workpiece) must
be 0.30 kg·m

Always set the Weight parameters according to the load. Setting a value that is
smaller than the actual load may cause errors, excessive shock and insufficient

The acceptable moment of inertia of load for a LS10-B series Manipulator is
When the moment of inertia of the load exceeds the rating, change the setting of the moment
of inertia parameter of the Inertia command. After the setting is changed, the maximum
acceleration/deceleration speed of Joint #4 at PTP motion corresponding to the "moment of
inertia" value is set automatically.
