CAUTION
The statement examples and program examples
are for a vertical 6-axis robot (e.g., RV-6SD).
hand advance/retrace direction relies on the
Z axis direction (+/- direction) of the tool coor-
dinate set for each model.
Refer to the tool coordinate system shown in
"Confirmation of movement" in the separate
"From Robot unit setup to maintenance", and
designate the correct direction.
