Setup & Operation 4. Setting of End Effectors
46 LS20 Rev.4
Eccentric Quantity and the Inertia Setting
CAUTION
■
eccentric quantity of load (weight of the end effector and work piece) must be
0 mm or less. The LS20 series Manipulators are not designed to work with
exceeding 200 mm.
Always set the eccentric quantity
parameter according to the eccentric quantity. Setting a value that is smaller
than the actual eccentric quantity may cause errors, excessive shock, insufficient
function of the Manipulator, and/or shorten the life cycle of parts/mechanisms
.
The acceptable eccentric quantity of load in LS20 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.

Eccentric quantity of load on the shaft
The eccentric quantity of load (weight of the end effector and work piece) on the shaft can
be set by “eccentric quantity” parameter of Inertia command.
Enter a value into the [Eccentricity:] text box on the [Inertia] panel (
[Tools] -
anager]). (You may also execute the Inertia command from the [Command Window].)
