, all rotations in the active frames, which could produce coordinate axis movements for non-existent geometry
axes, are deleted.
The data management frames are not changed. Only the possible rotations are applied when the data
management frames are activated.
Example:
No y axis exists:
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[0] = 1
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[1] = 0
MD20050 $MC_AXCONF_GEOAX_ASSIGN_TAB[2] = 3
$P_UIFR[1] = crot(x,45,y,45,z,45)
10.5.6.4 Mapped Frames
Overview
The "mapped frames" function supports the cross-channel consistent change of axial frames inside channel-
specific or global data management frames. Using axial machine data, it is defined between which axes mapping
is realized.
If frame mapping is e.g. active for machine axes AX1 and AX4, and the axial frame of axis AX1 is changed in a
channel-specific data management frame (e.g. basic frame $P_CHBFR[x]) (translation, fine translation, scaling,
mirroring), then this frame data for AX1 and AX4 is transferred to all channel-specific data management frames
(e.g. basic frame $P_CHBFR[x]) in all channels in which they are parameterized as channel axes.
Frame mapping is not realized when changing the axial frame data for the rotation.
Bit 0: Rotations in active frames, which rotate coordinate axes with no geometry axes,
are deleted from the active frames.
Bit 1: Shear angles in the active frames are orthogonalized.
Bit 2: Scalings of all geometry axes in the active frames are set to value 1.
