16.4 G function groups

16.4 G function groups
The G functions are divided into function groups. Only one G function of a group can be
programmed in a block. A G function can be either modal (until it is canceled by another
function of the same group) or only effective for the block in which it is programmed (non-
modal)

Configurability of the G function as a delete setting for the function group on power up,
reset or end of part program with MD20150 $MC_GCODE_RESET_VALUES:
+ Configurable
- Not configurable
Effectiveness of the G function:
m modal
n non-modal
Default setting
If no function from the group is programmed with modal G functions, the default setting,
which can be changed in the machine data
(MD20150 $MN_$MC_GCODE_RESET_VALUES), applies:
SAG Default setting Siemens AG
MM Default setting Machine Manufacturer (see machine manufacturer's
specifications)
The G function is not valid for NCU571.
