3.5 REDEF Changing the attributes of the NC language elements
Example: modal speed limitation in the parts program (setting data)
/_N_DEF_DIR/_N_SGUD_DEF
REDEF $SA_SPIND_MAX_VELO_LIMS PRLOC
M17
/_N_MPF_DIR/_N_MY_MPF
N10 SETMS (3)
N20 G96 S100 LIMS=2500
...
M30
Let the limit speed defined in setting data ($SA_SPIND_MAX_VELO_LIMS) speed limitation
be 1200 rpm. Because a higher speed can be permitted in a set-up and completely tested
parts program, LIMS=2500 is programmed here. After the end of the program, the value
configured in the setting data takes effect here again.
Reset settings to default values and delete initializations again

In particular, it is necessary to pay attention to the DEF.../ REDEF sequence for GUD.
(Setting data/system variables are implicitly created before the definition files are
processed). The symbol must always be defined first (implicitly by the system or by the
DEF statement) and only then can the REDEF be changed.
