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.

; 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.
