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
The PLC is informed when a geometry axis has been replaced using GEOAX( )
through the optional output of an M code that can be set in machine data
MD22532 GEOAX_CHANGE_M_CODE.
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.
• When the transformation is deactivated, the MD-defined basic setting for the geometry
axis configuration becomes valid again.
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
