Zero point shift amount
Set the amount to shift (move) from the position stopped at with machine zero
point return.
* The zero point shift function is used to compensate the zero point position
stopped at with machine zero point return.
If there is a physical limit to the zero point position, due to the relation of the near-
point dog installation position, use this function to compensate the zero point to an
optimum position.
