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 ori-
gin, so the Origin Stop Flag is turned ON. There will be no change in the status of
the Positioning Completed Flag.
1 scan min.
The origin return operation is used to return the axis to the origin from any posi-
tion. 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.
