Data description
9.1 Machine data for machine cycle runs
Memory requirement of GUD variables for meas. cycles
The machine data settings recommended above provide overall values that enable work with
measuring cycles. Deviating settings may be required for particular applications. The
memory requirement of each measuring cycle is therefore specified here (approximate
values). It may be higher in future measuring cycle versions.
The resulting memory requirement must be added to other user memory requirements.
The number of measuring programs "loaded" in the CNC, including the internal measuring
programs, are also added to the user's loaded NC programs!
If necessary, the general machine data MD 18280: MM_NUM_FILES_PER_DIR and MD
18320: MM_NUM_FILES_IN_FILESYSTEM has to be adapted!

Bit 5 = 1
Changes effective after POWER ON
Data type:INTEGER
Significance: The following applies to measuring cycles:
Bit 0: 1 system frames for preset mode and scratching, recommended
Bit 5: 1 system frames for cycles (must always be available for measuring cycles)
1) up to NCK software version 59.xx.yy
2) as of NCK software version 63.xx.yy
3) If bit 0 = 0, then corrections cannot be made in the basic frame in "Measuring in JOG" and the parameterization variant
KNUM=2000 cannot be used when measuring in automatic mode!
