Example 1
The channel axis is to become a geometry axis through geometry axis substitution.
The substitution is to give the programmable frame a translation component of 10 in the X
axis.
The current settable frame is to be retained:
FRAME_GEOX_CHANGE_MODE = 1
$P_UIFR[1] =
CROT(x,10,y,20,z,30)

GEOAX(1, a)
Several channel axes can become geometry axes on a transformation change.

Comment
; Activation of the NC global basic frame
; Activation of the NC global basic frame with rotation =>
alarm 18310, since rotations of NC global frames
are not permitted
Comment
; The NCU global basic frame is also active in second
channel
; Activate basic frame
; Current frame of second channel is activated with an
offset
; Frame is retained after geo axis substitution.
; Settable frame becomes active.
; Axial offset of a is also substituted.
; A becomes x axis.
; $P_ACTFRAME= CROT(x,10,y,20,z,30):CTRANS(x10)
