Programming
G25 X...Y...Z... Programming in a separate NC block
Or
G26 X...Y...Z... Programming in a separate NC block
Or
WALIMON
Or
WALIMOF
Parameters
G25, X Y Z
G26, X Y Z
WALIMON
WALIMOF
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 de-activating 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/de-activation, 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 further
information, please refer to "Feed control and spindle motion".
