Supplementary conditions
As a basic rule, any channel axis designated as a geometry axis can be replaced by another
channel axis.
In this case, the following restrictions apply:
•
Rotary axes may not be programmed as geometry axes.
•
A geometry axis, which has the same name as a channel axis, cannot be replaced by
another channel axis (alarm message). Nor can an axis of this type be removed from the
geometry axis grouping. It cannot change its position within the geometry axis grouping.
•
Both axes in each of the axis pairs involved in the replacement operation must be block-
synchronized.
•
The following functions may not be active when geometry axes are replaced:
–
Transformation
–
Spline interpolation
–
Tool radius compensation
–
Tool fine compensation
•
Any active DRF offset or zero offset external will remain operative. They both act on
channel axes. The channel axis assignment is not affected by the replacement of
geometry axes.
Replacement of geometry axes
All frames, protection zones and working area limitations are deleted. They may need to be
reprogrammed after the replacement operation.
The system response to replacement of geometry axes is, therefore, identical to its response
to a change (switch on/off, switchover) in a kinematic transformation.
Tool Length Compensation
Any active tool length compensation remains operative and is applied to the new geometry
axes after replacement.
The system treats tool length compensations as not yet applied for the following geometry
axes:
•
All geometry axes, which have been newly added to the geometry axis grouping
•
All geometry axes, which have changed their positioning within the geometry axis
grouping
Geometry axes, which retain their position within the geometry axis grouping after a
replacement operation, also retain their status with respect to tool length compensation.
