operation, considering near-point dog ON as "0", is stored.
[5] Setting the OP shift function
To use the "OP shift function", set the required details in the parameters shown in
the following table, and write them to the Simple Motion module.
When the parameters are set, the OP shift function will be added to the machine
OPR control. The set details are validated at the rising edge (OFF
ON) of the
PLC READY signal [Y0].

REMARK
Parameters are set for each axis.
It is recommended that the parameters be set whenever possible with GX Works2.
Execution by sequence program uses many sequence programs and devices. The
execution becomes complicated, and the scan times will increase.
