In addition to programming values using G25/G26, values can also be entered using axis-
specific setting data:
SD43420 $SA_WORKAREA_LIMIT_PLUS (Working area limitation plus)
SD43430 $SA_WORKAREA_LIMIT_MINUS (Working area limitation minus)
Activating and deactivating the working area limitation, parameterized using SD43420 and
SD43430, are carried out for a specific direction using the axis-specific setting data that
becomes immediately effective:
SD43400 $SA_WORKAREA_PLUS_ENABLE (Working area limitation active in the positive
direction)
SD43410 $SA_WORKAREA_MINUS_ENABLE (Working area limitation active in the negative
direction)
Using the direction-specific activation/deactivation, it is possible to limit the working range for
an axis in just one direction.
Note
The programmed working area limitation, programmed with G25/G26, has priority and
overwrites the values entered in SD43420 and SD43430.
Note
G25/G26 can also be used to program limits for spindle speeds at the address S. For more
information see " Programmable spindle speed limitation (G25, G26) (Page 104) ".
