Defines the coordinate value of the second reference point in the machine coordinate system. 3. Procedure for Adjusting Reference Position

: Sets the distance of the home position from the reference position.

: These define the travel limits for each axis. If the machine "homes" too early or crashes, these values may be incorrect.

To achieve a reference return on a Fanuc 0T:

If the zero return procedure is performed too fast, the axis might overshoot the grid pulse, causing a one-turn error. Reducing the rapid rate for reference return can improve consistency.
