2.2.3 Commissioning
2.2.3.1 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.
Special functions: Axis Couplings and ESR (M3)
