Origin search
If the ORG(889) (ORIGIN SEARCH) instruction is executed
and the origin search function is enabled in the PLC Setup,
the origin search operation will start and the origin location
will be determined based on the Origin Proximity Input Sig-
nal and Origin Input Signal. At this point, the coordinates for
the pulse output PV will automatically be set to absolute
coordinates.
Note
Outputs OUT4/OUT5 are used for the Error Counter
Reset Outputs.
Inputs IN0 through IN5 are used for the Origin Input
Signals, Origin Proximity Input Signals, and Posi-
tioning Completed Signals. (The Error Counter
Reset Output and Positioning Completed Signal are
not used in all origin search operating modes.)
Origin return
If the ORG(889) (ORIGIN SEARCH) instruction is executed
and the origin search function is enabled in the PLC Setup,
the origin return operation will move the system to the pre-
determined origin location.
