; Transformation on.
; Activation of online tool length compensation
for the Z tool direction.
; A TLC of 10 is interpolated for the Z tool
direction.
; Activation of online tool length compensation
for the X tool direction.
; For the X tool direction compensation is
implemented depending on the position of axis
X2.
; Assigns actual compensation in the X direction.
For the X tool direction, the TLC is reduced
back to 0:

; Position offset of the X tool direction is
deleted:
...$AA_TOFF[X]=0
No axis is moved.
The position offset is added to the actual
position in the Work corresponding to the actual
orientation.
