I/O assignment selection parameter description
The I/O assignment selection parameter (single-axis controllers: PRM59, dual-axis con-
trollers: PRM26) selects the function to be assigned to each I/O signal.
This parameter setting allows changing the function assigned to each I/O signal. This
makes it possible to output the destination point number and perform jog movement.
After changing the I/O assignment, the controller must be restarted to enable the changes.

Description
Value
Outputs PO when movement ends normally.
Outputs PO when movement command is received.
Point zone output
Outputs PO when the robot enters the
±
position judgment parameter
range for point data registered in the controller.
Movement point zone output
Outputs PO when the robot enters the
±
position judgment parameter
range for point data that is registered in the controller and serves as the
movement target position of a point movement command (ABS-PT,
INC-PT).
