Activation
Axis replacement is activated by the program command:
GEOAX([n, channel axis name]...)
n=0:
n=1, 2, 3:
GEOAX( ):
Channel axis name:
A channel axis, which has been designated a geometry axis, can only be addressed under
its geometry axis name. The geometry axes names themselves remain unchanged.
Geometry axes can be replaced either individually or as a group in one command.
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
• Both axes in each of the axis pairs involved in the replacement operation must be block-
• The following functions may not be active when geometry axes are replaced:
• Any active DRF offset or zero offset external will remain operative. They both act on
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.
