The following cycles become effective automatically as soon as they
are defined in the part program. These cycles cannot and must not be
called:
n Cycle G220 for circular and Cycle G221 for linear hole patterns
n SL Cycle G14 CONTOUR GEOMETRY
n
SL cycle G20 CONTOUR DATA (not TNC 410)
n Cycle G62 TOLERANCE (not TNC 410)
n Coordinate transformation cycles
n Cycle G04 DWELL TIME
All other cycles are called as described below:
1 If the TNC is to execute the cycle once after the last programmed
block, program the cycle call with the miscellaneous functionM99
or with G79.
2 If the TNC is to execute the cycle automatically after every
positioning block, program the cycle call with M89 (depending on
machine parameter 7440).
3 only TNC 410: If the TNC is to execute the cycle at every position
that is defined in a point table, use the function G79 PAT (see “Point
Tables” on page 180).
To cancel M89, enter
n M99 or
n G79 or
n a new cycle.
