9.4 Compatibility with Earlier OEM Cycles
The following possibilities are provided to enable you to continue using earlier
OEM cycles with program numbers 999 999 68.H to 999 999 99.H on the TNC.
Earlier OEM cycle:
n Use CycleDesign to include the cycle in the cycle structure of the TNC. Like
a standard cycle, the cycle can be defined and called via soft key under
dialog guidance.
n You can have the cycle run only in existing NC programs. The cycle cannot
be used by the TNC user in the new NC programs, but existing NC programs
containing the cycle can be run.
You can access earlier OEM cycles, even without CycleDesign.
Earlier OEM cycle:
n Call with CYCL DEF 12 (program call) and CYCL CALL. The cycle cannot be
programmed by soft key. It is defined with CYCL DEF 12 and then called with
CYCL CALL or M99.
n Call with PGM CALL. The cycle cannot be programmed by soft key. It is called
with PGM CALL.
You will find detailed information about the use of earlier OEM cycles in the
User's Manual for CycleDesign.
