N100 $P_NCBFR[0] = CTRANS( x, 10 ) ; Activation of the NC global basic frame
. . .
N130 $P_NCBFRAME[0] = CROT(X, 45) ; Activation of the NC global basic frame with rotation =>
alarm 18310, since rotations of NC global frames
are not permitted

Part program in second channel
Code (excerpt) Comment
. . .
N100 $P_NCBFR[0] = CTRANS( x, 10 ) ; The NCU global basic frame is also active in second
channel
. . .
N510 G500 X10 ; Activate basic frame
N520 $P_CHBFRAME[0] = CTRANS( x, 10 ) ; Current frame of second channel is activated with an
offset

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)
; Frame is retained after geo axis substitution.
G54 ; Settable frame becomes active.
TRANS a10 ; Axial offset of a is also substituted.
GEOAX(1, a) ; A becomes x axis.
; $P_ACTFRAME= CROT(x,10,y,20,z,30):CTRANS(x10)
Several channel axes can become geometry axes on a transformation change.
