The working area limitation for all validated axes must be programmed with the
command. The
default setting. Therefore, it only has to be programmed if the working area limitation has
been disabled beforehand.

In addition to programming values using
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
overwrites the values entered in SD43420 and SD43430.
