Configuration
MD18112 $MN_MM_KIND_OF_SUMCORR, bit 4=0: (Properties of sum offset in the TO area)
default setting:
Only one set of sum offsets exists per DL number.
We refer in general to the sum offset.
This describes the data represented by $TC_SCPx.
Figure 18-50 MD18112 $MN_MM_KIND_OF_SUMCORR, bit 4 = 0
Tool T = t is active. With the data in the figure, the following is programmed:
D2
...
DL=1
...
DL=2
...
DL=0
MD18112 $MN_MM_KIND_OF_SUMCORR, bit 4=1: Setup offsets are available
The sum offset is now composed of the "sum offset fine" (represented by $TC_SCPx) and the
setup offset (represented by $TC_ECPx). Two data sets therefore exist for one DL number.
The sum offset is calculated by adding the corresponding components ($TC_ECPx +
$TC_SCPx).

; Cutting edge offsets, i.e., $TC_DP3 to $TC_DP11 + wear
($TC_DP12 to $TC_DP20) + adapter dimension
; Sum offset 1 is added to the previous D2 compensations, i.e.,
$TC_SCP13 to $TC_SCP21.
; Sum offset 2 is added to the D2 compensation instead of sum
offset 1, i.e., $TC_SCP23 to $TC_SCP31.
; Deselection of sum offset;
only the data of D2 remain active.
