The acceptable moment of inertia of load for a LS20-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.
