Restrictions
After an external or internal stop, you can only re-enter the
contour with the function RESTORE POS. AT N. Before you start
the block scan, you must cancel M120, otherwise the TNC will
output an error message.
If you want to approach the contour on a tangential path, you
must use the function APPR LCT. The block with APPR LCT
must contain only the coordinates of the working plane.
If you want to depart the contour on a tangential path, you
must use the function DEP LCT. The block with DEP LCT must
contain only the coordinates of the working plane.
Before using the functions listed below, you have to cancel
M120 and the radius compensation:
Cycle G60 Tolerance
Cycle G80 Working plane
PLANE function
M114
M128
