Timing Chart
In the following timing chart, the X-axis present position for a 4-axis PCU is
changed to “0.” When the present position is changed to “0” it becomes the
origin, so the Origin Stop Flag is turned ON. There will be no change in the
status of the Positioning Completed Flag.

Origin Return
The origin return operation is used to return the axis to the origin from any
position. It is executed by the rising edge of the ORIGIN RETURN command.
Note
Execute ORIGIN RETURN when the origin has been established. If the origin
has not been established, a present position unknown error (error code 5040)
will be generated.
