Axis state after replacing
An axis replaced by the changeover in the geometry axis group can be programmed as
supplementary axis after the changeover operation via its channel axis names.
Frames, protection areas, working area limits
All frames, protection areas and working area limits are deleted after changing over the
geometry axes.
Polar coordinates
Replacing the geometry axes with GEOAX sets analog to a level change with G17-G19, the
modal polar coordinates to a value of 0.
DRF, WO
A possible handwheel offset (DRF) or an external work offset (WO) remains effective after the
changeover.
Basic configuration of the geometry axes
The GEOAX() command calls the basic configuration of the geometry axis group.
The system automatically changes back to the basic configuration after POWER ON and when
changing over into the "reference point approach" mode.
Tool length compensation
An active tool length compensation is also effective after the changeover operation. However,
for geometry axes that have been newly added or those where the position has been replaced,
it is still considered not to have been moved through. For the first motion command for these
geometry axes, the resulting traversing distance correspondingly comprises the sum of the tool
length compensation and the programmed traversing distance.
Geometry axes, which retain their position in the axis group after a replacement operation, also
retain their status with respect to tool length compensation.
Geometry axis configuration for active transformation
● The geometry axis configuration parameterized for an active transformation via
transformation machine data cannot be changed using the "Switchable geometry axes"
function.
● Different data sets must be parameterized in the transformation machine data for a different
geometry axis configuration for a transformation.
● A geometry axis configuration changed using GEOAX is deleted by activating a
transformation.
● With regard to the geometry axes, the transformation-specific geometry axis
parameterizations of active transformations have priority over the parameterizations
relevant for the changeover of geometry axes.
Example: A transformation is active. According to the machine data, the transformation
should be retained at a channel reset. At the same time, the basic configuration of the
geometry axes should be restored at a channel reset. The geometry axis configuration that
has been specified for the transformation is retained.
● If a transformation is switched off, the parameterized basic setting of the geometry axis
configuration takes effect again.
