available for the user is entered in MD18230 (including optional memory expansion).
Default values are entered in all other memory-configuration machine data.
4. Set the sizes of partitions U and M in machine data:

(end-user memory for part programs/cycles/files)
MD18353 $MN_MM_M_FILE_MEM_SIZE
(memory size for cycles/files of the machine manufacturer)
5. Activate the number of required channels and axes.

areas of the active file system (tool management, global user data, etc.) for each user.
