(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
48) is valid only
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48)
when using an infinite
length axis.
Example:
When setting the current stop position to 0 (zero point position for the machine coordinate
system), set OL

48 to 0.
* 2. Execute with the ZSET command.
Repeat for every axis.
Start
Servo ON
STEP to move to
the zero point.
End
JOG to move close to
the zero point.
YES
NO
Set the zero point.
*2
Set the desired position at
OL
48.

Has the setting for the required
axis been completed?
