„ 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.
„ When using the path functions RND and CHF, the blocks before and
after RND or CHF must contain only coordinates in the working plane.
„ 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 coordinates of the working plane.
„ If you want to depart the contour on a tangential path, use the
function DEP LCT. The block with DEP LCT must contain only
coordinates of the working plane.
„ Before using the functions listed below, you have to cancel M120
and the radius compensation:
„ Cycle 32 Tolerance
„ Cycle 19 Working plane
„ PLANE function
„ M114
„ M128
