Geometry axes that maintain their position in the
axis group after a switchover also maintain their
status as regards the tool length compensation.
Geometry axis configuration and transformation
change
The geometry axis configuration that applies to an
active transformation (defined in the machine data)
cannot be changed with the function "Switchable
geometry axes".
If you need to change the geometry axis
configuration with transformation, this can only be
done by programming another transformation.
A geometry axis configuration changed with GEOAX
is cleared by activating a transformation.
If the machine data settings for the transformation
and for the geometry axis switchover conflict, the
settings for the transformation take priority.
Example:
A transformation is active. According to the settings
in the machine data the transformation is to remain
active after a RESET, at the same time, however,
the RESET is to reestablish the basic configuration
of the geometry axes. In this case the geometry axis
configuration defined with the transformation is
maintained.
