Approaching a reference point
When the "Reference point approach" mode is selected, the geometry axis configuration
defined by the machine data is automatically set.
M code
A changeover of the geometry axis with GEOAX( ) can be communicated to the PLC
through the output of an M code:
MD22532 $MC_GEOAX_CHANGE_M_CODE (M-Code during tool holder change)
Note
If this machine data is set to one of the values 0 to 6, 17, 30, then no M code is output.
Transformation changeover
The following interrelationships must be noted with respect to kinematic transformation and
geometry axis replacement:
• Geometry axis assignments cannot be modified when the transformation is active.
• Activation of a transformation deletes the programmed geometry axis configuration and
replaces it by the geometry axis assignment stored in the machine data of the activated
transformation.
• The initial setting defined through MD for the geometry axis configuration becomes
effective after deactivating the transformation.
Should it be necessary to modify the geometry axis assignment in connection with
transformations, then another new transformation must be configured. The total number of
the transformations simultaneously available in the channel is equal to 8.
A maximum of two transformations per channel can be available simultaneously from the
transformation groups below:
• Orientation transformations
(3-axis, 4-axis, 5-axis and nutation transformation)
• TRAANG (oblique axis)
• TRANSMIT
• TRACYL
