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