Overwriting curve tables
Curve tables that are not active in a master value coupling and are locked with CTABLOCK()
may be overwritten.
Deleting curve tables
Curve tables that are not active in a master value coupling and are locked with CTABLOCK()

Memory configuration

A defined storage space is available for the curve tables in the static and dynamic NC memory,
which is defined through the following machine data:
Static NC memory
MD18400 $MN_MM_NUM_CURVE_TABS
MD18402 $MN_MM_NUM_CURVE_SEGMENTS
MD18403 $MN_MM_NUM_CURVE_SEG_LIN
MD18404 $MN_MM_NUM_CURVE_POLYNOMS
Dynamic NC memory
MD18406 $MN_MM_NUM_CURVE_TABS_DRAM
MD18408 $MN_MM_NUM_CURVE_SEGNENTS_DRAM
MD18409 $MN_MM_NUM_CURVE_SEG_LIN_DRAM
MD18410 $MN_MM_NUM_CURVE_POLYNOMS_DRAM
Note
A curve table with linear segments can be stored efficiently in the memory only if:
MD18403 > 0 or MD18409 > 0
If no memory areas are created with this machine data, then the linear segments are stored as
polynomial segments.
