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
(select program again via PGM MGT, do not use
GOTO 0), 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 enter an LA value that is too great, the edited
contour might change, because the TNC might then
output too many NC blocks
„ 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
„ M138
„ M144
