Commissioning

You can adjust the default memory division by increasing/decreasing individual memory areas
for each user.
Basic procedure:
1. Load standard machine data.

Commissioning the CNC: NC, PLC, Drive; section "Requirements for commissioning" >
"Power-on and startup"
2. Determining the maximum possible size of the static user memory (including the optional
memory expansion):
MD18230 $MN_MM_USER_MEM_BUFFERED
3. Optional: modifying the size of the static user memory:
– MD19250 $ON_USER_MEM_BUFFERED
– Perform a power-on reset.
4. Optional: setting the size partitions U and M:
– MD18352 $MN_MM_U_FILE_MEM_SIZE
– MD18353 $MN_MM_M_FILE_MEM_SIZE
5. Optional: setting up additional channels of the control:
MD10010 $MC_ASSIGN_CHAN_TO_MODE_GROUP
6. Optional: setting the size of the memory areas of the active file system (tool management,
global user data, ...):
– Determining the free static user memory:
– Setting the size of the memory areas of the active file system in the machine data that
7. Perform a power-on reset.
The memory will be reconfigured the next time the control starts up.
