Notes

1. Positional repeatability calculated after operating conditions stabilize from repeated automatic operations.
2. The value shown in ( ) indicates wall-mounted conditions.
3. Positional data protected by battery-backed storage inside the manipulator.
4. When the output flange of the wrist axis is loaded with maximum payload capacity.
5. Working range of J6 axis may be restricted by the position of J5 axis.
