SECTION 6
Defining the Origin
This section explains the origin search and origin return operations. With memory operation, if positions are designated by
absolute values, or if the ABSOLUTE MOVEMENT command is executed by direct operation, it will be essential to
execute an origin search and establish the origin before positioning.
Origin return is used to return the axis to the origin from any given location. Any location can be made the origin by using
the PRESENT POSITION PRESET command to change the present position to 0. Refer to
6-6 Present Position Preset
for
information on resetting the present position.
