Precondition: 1) The following steps are explained assuming that the I/O assign-
ment selection parameter (single-axis controllers: PRM59, dual-
axis controllers: PRM26) is set to 30.

2) The point numbers of the target positions are designated before
running a point movement command (ABS-PT, INC-PT).
[Point movement command execution q]
(1) To specify the movement axis by a dual-axis controller, input the axis designa-
tion data to SI213 and SI214.
• The input status specified here must be kept unchanged until step (3) is com-
plete. If this input status is changed, the controller might misrecognize the
data.
(2) Turn on the ABS-PT (or INC-PT).
(3) The END signal turns off and the BUSY signal turns on, indicating that the
controller received the point movement command.
(4) Turn off the ABS-PT (or INC-PT).
(5) Wait until the BUSY signal turns off.
(6) The BUSY signal turns off. The END signal should be on at this point, indicat-
ing that the point movement is normally finished.
(7) When the END signal is on in step (6), the target position's point number is
output from the specified point number (PO200 to PO205).
• The output status of the target position's point number is retained until ex-
ecution of the next point movement command is complete.

*1 For dual-axis controllers only. In the case of dual-axis controllers, all axes are usually
used for movement. However, the desired axis can be specified with SI213 and SI214
by enabling PRM10 (Control axis selection with I/O command).
*2 The number of point number outputs that can be used depends on the I/O assignment type.
