10.5.6 Implicit frame changes
10.5.6.1 Frames and switchover of geometry axes
In the channel, the geometry axis configuration can be changed by switching a transformation on and off and with
the GEOAX() command (R3).
Machine data
MD10602 $MN_FRAME_GEOAX_CHANGE_MODE
can be used to configure, for all channels of the system, whether the current complete frame is calculated again
on the basis of the new geometry axes or whether the complete frame is deleted.
Four modes can be set via machine data:
• MD10602 $MN_FRAME_GEOAX_CHANGE_MODE = 0
The current complete frame is deleted when geometry axes are switched over, when transformations are
selected and deselected, and on GEOAX().
The modified geometry axis configuration is not used until a new frame is activated.
• MD10602 $MN_FRAME_GEOAX_CHANGE_MODE = 1
The current complete frame is calculated again when the geometry axes are switched over, and the
translations, scales and mirrors of the new geometry axes are effective. The rotations of the geometry axes,
which were programmed before the switchover, remain effective for the new geometry axes.
The aspects described in the chapter "Frames for selection and deselection of transformations" are relevant
to TRANSMIT, TRACYL and TRAANG.

• MD10602 $MN_FRAME_GEOAX_CHANGE_MODE = 2
The current complete frame is calculated again when the geometry axes are switched over, and the
translations, scales and mirrors of the new geometry axes are effective. If rotations are active in the current
basic frames, the current settable frame or the programmable frame before the switchover, it is aborted with
the alarm "Frame: Geometry axis switchover not allowed".
The aspects described in the chapter "Frames for selection and deselection of transformations" are relevant

• MD10602 $MN_FRAME_GEOAX_CHANGE_MODE = 3
The current frame is deleted when selecting and deselecting transformations.
With GEOAX(), the current complete frame is calculated again and the translations, scales and mirrors of the
new geometry axes come into effect.
The rotations of the geometry axes, which were programmed before the switchover, remain effective for the
new geometry axes.
