Origin Return
The origin return operation is used to return the axis to the origin from any
position. ORIGIN RETURN is executed when the ORIGIN RETURN Bit turns
ON.
Note
Execute ORIGIN RETURN when the origin has been established. If ORIGIN
RETURN is executed when the origin has not been established, a Present
Position Unknown Error (axis error code: 3030) will occur.

Origin Return Data Settings
A simple explanation of the main parameters and data used to execute ORI-
GIN RETURN is provided here. To execute ORIGIN RETURN, apart from the
parameters explained here, the following parameters also need to be set as
basic settings for operating the PCU.
For details on command units, refer to
7-2 Control Units
. The setting units for
parameters and data depend on the specified command unit.
