13.2.2 HP shift function [RJ010 mode]
When a machine HPR is carried out, the HP is normally established using the
proximity dog or zero signal. However, by using the HP shift function, the machine can
be moved a designated movement amount from the position where the zero signal
was detected. A mechanically established HP can then be interpreted at that point.
The details shown below explain about the "HP shift function".
