4-1 Outline of Defining the Origin
4-1
To perform positioning of the absolute position for the system that requires positioning, you
must define the origin first.
For example, If you want to perform positioning to the position (axis 1, axis 2) = (100 mm, 200
mm) in the XY plane as shown below, you must determine the mechanical origin (0,0).
This process of determining the mechanical origin is called defining the origin.
This PCU has two functions below to determine the mechanical origin:
Also, the Origin Return function below is available to return to the origin which you determined
by the above methods.

Actually move the motor and use the limit sensor, origin proximity sensor, and input
signal that indicates the origin, to determine the origin.
Use the proximity sensor, encoder phase Z, etc. for the input signal that indicates the
origin.
Forcibly set an arbitrary value for the position where the motor currently stops to
determine the origin. This PCU has 3 types of present position preset functions.
For details, refer to "Present Position Preset" on page 4-36.
Positioning is performed to the origin which you determined by Origin Search or present
position preset, from the position where the motor currently stops.
