Machine-specific cycles

In addition to the HEIDENHAIN cycles, many machine tool builders
offer their own cycles in the TNC. These cycles are available in a
separate cycle-number range:
Cycles 300 to 399
Machine-specific cycles that are to be defined through the
CYCLE DEF key
Cycles 500 to 599
Machine-specific touch probe cycles that are to be defined
through the TOUCH PROBE key
Refer to your machine manual for a description of the
specific function.
Sometimes machine-specific cycles use transfer parameters that
HEIDENHAIN already uses in standard cycles. For parallel use of
DEF active cycles (cycles that the TNC is automatically running
during cycle definition) and CALL active cycles (cycles that you
need to call up to run).
Further information:
Adhere to the following procedure in order to avoid problems
regarding the overwriting of transfer parameters that are used
more than once:
As a rule, always program DEF-active cycles before CALL-active
cycles
If you do want to program a DEF-active cycle between the
definition and call of a CALL-active cycle, do it only if there is no
common use of specific transfer parameters
