Part 4 Commands
A. 3-point teaching method
To set the palletizing positions by 3-point teaching, store desired positions in position data fields
as three continuous position data and then specify the first position number using a PAPS
command.
This method allows you to set the PX-axis and PY-axis as three-dimensional axes not parallel
with the load coordinate system axes and not crossing with each other.
In the example shown below, position data [1], [3] and [10] are stored in three continuous
position data fields.
When three points are taught from position No. 11
Position No. 11
[1]: Reference point
Position No. 12 [3]: The end point in the PX-axis direction
Position No. 13 [10]: The end point in the PY-axis direction
(Position No. 14 [12]: End point (4-point teaching))
The encircled numbers indicate palletizing position numbers (palletizing order).
Use a PAPS command to specify the position number corresponding to the start point.

PAPS 11
PEXT 14
Do no enter anything in the R-axis data column of the position data specified by a PAPS
command. (Alternatively, disable the R-axis using a GRP command.)
Use a PEXT command to set the R-axis coordinate of a given palletizing position.
Preferential axis
(PX-axis)
Start point
(PY-axis)
The pitches are calculated automatically
from the count set for each axis.
In 3-point teaching, you can specify
position data for the X and Y-axes only or
for X, Y and Z-axes. If data is specified for
three axes, the palletizing plane will
become a three-dimensional plane.
