Supplementary conditions
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 zones, working area limits
All frames, protection zones 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, ZO
A possible handwheel offset (DRF) or an external zero offset (ZO) 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 applicable in an active transformation (defined using
machine data) cannot be changed using the function "replaceable geometry axes".
Should it be necessary to modify the geometry axis configuration in conjunction with
transformations, then this is only possible using an additional transformation.
A geometry axis configuration changed using
GEOAX is deleted by activating a transformation.
If the machine data settings for the transformation do not match those for changing over
geometry axes, then the settings in the transformation have priority.
Example:
One transformation active. According to the machine data, the transformation should be kept
for a reset; however, at the same time, for a reset, the basic configuration of geometry axes
should be established. In this particular case, the geometry axis configuration that was
defined with the transformation is kept.
