10.3.2 Infinite Length Axis
(5) Setting the Zero Point for an Infinite Length Axis
Execute the ZSET motion command (zero point setting).
The system will settle pulse position at power OFF, encoder position at power OFF, and all position data when
the zero point is set.
The following illustration shows the procedure for setting the zero point for an infinite length axis.
* 1. For an infinite length axis, the Zero Point Offset (setting parameter OL

Has the setting for the required
axis been completed?
End
when the ZSET command is executed.
Therefore, the OL 48 value doesn't have to be memorized in a M register.
Set the desired coordinate value in the Zero Point Offset (OL

Example:
When setting the current stop position to 0 (zero point position for the machine coordinate
system), set OL 48 to 0.
Repeat for every axis.
