Not all possible combinations of the three parameters _COMP, _CORCOMP and _CORMODE are sensible. For
example, algorithm 3 in _CORCOMP requires that two characters are specified in _COMP. If an invalid
parameter combination is specified, then a corresponding error code is returned in the status.
Example 1
_DL INT
Number of the offset dependent on the location. If this parameter is not specified, the DL
number used is based on the source of the T number. If the T number from the tool
environment is used, the D number of the tool environment is also read, otherwise the D
number of the currently active tool is read. If T, D and DL specify a tool without location-
dependent offsets, no additive or setting-up offsets may be specified in parameter
_COMP (error code in "Status").
Note
Calculating the tool length depending on machine data MD20360
The two least significant bits of this machine data specify how the wear (bit 0) and tool length
(bit 1) are to be evaluated if a diameter axis is used for turning and grinding tools. If the
appropriate bits are set, then for the tool length calculation, a factor of 0.5 is applied to the
associated entry. The correction using SETTCOR is executed so that the total effective tool
length change is equal to the value transferred in _CORVAL.
The correction of the components, whose length is evaluated with a factor of 0.5 due to the
following machine data for the length calculation, must be realized using twice the transferred
value:
