Activation
In order to work with unique D numbers and, therefore, with the defined language commands,
it must be possible to name D numbers freely for the tools.
The following conditions must be fulfilled for this purpose:
● MD18105 > MD18106
● The 'flat D number' function is not activated.
MD18102 $MN_MM_TYPE_OF_CUTTING_EDGE (type of D number programming
(SRAM)).
Examples
MD18105 $MN_MM_MAX_CUTTING_EDGE_NO = 1 (max. value of the D numbers)
A maximum of one compensation can be defined per tool (with D number = 1).
Note
When the "Flat D numbers" function is active, only one D compensation can be defined in the
TO unit.
MD18105 $MN_MM_MAX_CUTTING_EDGE_NO = 9999
Tools can be assigned unique D numbers.
