(7) Changing the Tool Offset Amount in the Offset Mode
There are two kinds of offset amount changing methods (types A and B), and the method
to be used can be selected by the setting for a parameter.
(a) Type A: pm4013 D2 = 0
When a new D code is specified, the new offset data are calculated from the axis move
commands given in the block including the new D code and the next block.

(b) Type B: pm4013 D2 = 1
When a new D code is specified, the new offset data are calculated from the axis move
commands given in the block including the new D code and the preceding block.
