Eccentric Quantity and the Inertia Setting
CAUTION
■
The
eccentric quantity of load (weight of the end effector and workpiece) must be
200 mm
or less. The LS20-B series Manipulators are not designed to work with
eccentric quantity
exceeding 200 mm.
Always set the Weight parameters according to the load. Settin
g a value that is
smaller than the actual load may cause errors, excessive shock and insufficient
function of the Manipulator. Also, the life cycle of parts is shortened and
positional
gap due to belt tooth bumping occurs.
The acceptable eccentric quantity of load in LS20-B series is 0 mm at the default rating and
200 mm at the maximum. When the eccentric quantity of load exceeds the rating, change
the setting of eccentric quantity parameter of Inertia command. After the setting is
changed, the maximum acceleration/deceleration speed of the Manipulator at PTP motion
corresponding to the “eccentric quantity” is set automatically.
