D Number Programming - Siemens SINUMERIK 840D sl Function Manual

MD18100 $MN_MM_NUM_CUTTING_EDGES_IN_TOA (tool compensations in TO area).
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:
