• 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.
RESET
The reset behavior of the changed geometry axis assignment is defined with the following machine data:
MD20110 $MC_RESET_MODE_MASK (definition of initial control system settings after RESET/TP-End)
MD20118 $MC_GEOAX_CHANGE_RESET (allow automatic geometry axis change)
MD20110 $MC_RESET_MODE_MASK
Bit Value Significance
12 0 In case of set machine data MD20118$MC_GEOAX_CHANGE_RESET (allow
automatic geometry axis change) a changed geometry axis assignment is deleted
during reset or parts program end.
The initial setting defined in the machine data for the geometry axis assignment
becomes active.
1 A modified geometry axis assignment remains active after a reset/part-program end.
