D Number Programming - Siemens SINUMERIK 828D Function Manual

Data backup
Data backup is carried out in the same format, i.e., a backup file created with the "Flat D number" function cannot
be loaded on the NCK of a control that has not activated the function.
This also applies in reverse for transfer.
D range
1 - 99 999 999

D number programming

MD18102 = 1
If MD18102 $MN_MM_TYPE_OF_CUTTING_EDGE = 1, then D compensation is activated without reference to a
certain tool.
D0 still contains the previous significance, "Deselection of active compensation in NCK".
Address extension of D
It is not possible to extend the address of D. Only one active compensation data block is possible for the tool path
at a given time.
Programming
Programming in the part program is carried out as before. Only the value range of the programmed D number is
increased.
Example 1:
MD parameterization
MD22550 $MC_TOOL_CHANGE_MODE
MD18102 $MN_MM_TYPE_OF_CUTTING_EDGE
MD20270 $MC_CUTTING_EDGE_DEFAULT
