Offset Number: _Knum - Siemens SINUMERIK 840D sl Programming Manual

2.3.4

Offset number: _KNUM

Parameter
With measuring variant _MVAR you can select whether automatic tool offset will be used or
a zero offset will be corrected in a workpiece measuring cycle.
Parameter _KNUM contains the
● tool offset memory number (D number)
● code for the zero offset to be corrected .
Values of _KNUM: ≥0, integer
1. Specification _KNUM for tool offset, 7 digits:
_KNUM can accept values with up to 7 digits (for special MD settings, even 9 digit values).
_KNUM=0: no automatic tool offset
In the default setting, the D number has values between 0 and 9.
Depending on MD 18102: MM_TYPE_OF_CUTTING_EDGE = 0 and MD 18105:
MM_MAX_CUTTING_EDGE_NO and a value of this MD of between 10...999, the last three
digits are read as a D number.
With a value ≥1000, _KNUM is evaluated as a 5-digit D number (unique D number, as in flat
D number structure, see next Section).
