Chapter 13 Control Sub Functions
13.2.2 OP shift function
When a machine OPR is carried out, the OP is normally established using the near-
point dog or zero signal. However, by using the OP shift function, the machine can be
moved a designated movement amount from the position where the zero signal was
detected. A mechanically established OP can then be interpreted at that point.
The details shown below explain about the "OP shift function".
