x When setting palletizing positions by 4-point teaching, it is recommended that the non-planar type
specification be used if you know all four points are on a plane and if palletizing precision is required.

The plane is determined by three points including the start point, end point in PX-axis direction
DQGHQGSRLQWLQ3direction) and use the intersecting point with the aforementioned plane as the end point of non-
planar palletizing.
The palletizing positions are arranged to the pallet surface of the quadrate shape which is
determined by these four points.
Take note, however, that if the three points other than the end point meet the conditions shown in
Table 1, the moving direction of the end point will vary. This occurs when the plane determined
by three points other than the end point is vertical to the ground, because in this case moving the
