Power-up G-code Parameters
Chapter 19
19-7
Function
This parameter selects the default G-code for modal group 3. The selected
G-code specifies whether the control operates under G-code G90
(Absolute) or G91 (Incremental) positioning at power-up or reset.
Important: When control type “Lathe” and G-code system A is selected,
this parameter is ignored. Absolute or incremental moves are determined
by the axis word that is used to program the move.

Notes
This is a global parameter. The value set here applies to all axes.
For dual--processing controls, this is a per process parameter. The value set
in the parameters applies to all of the axes assigned to that process.
