2-9-3 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.
MEMO
MEMO
The I/O assignment selection parameter is supported by the following controller ver-
sions:
ERCX, SRCX : Ver. 13.57 or later DRCX : Ver. 18.57 or later
SRCP, SRCD : Ver. 24.17 or later SRCP30 : Ver. 24.30H or later

DescriptionValue
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).
MEMO
MEMO
The movement point zone output is supported by the following
controller versions:
ERCX, SRCX : Ver. 13.64 or later DRCX : Ver. 18.64 or later
SRCP, SRCD : Ver. 24.21 or later SRCP30 : Ver. 24.30H or later
