Detailed Description
2.9 Sum offsets and setup offsets
Data backup
The data are saved during a general tool-data backup (as a component of the D number
data sets).
It is advisable to save the sum offsets, in order to allow the current status to be restored in
the event of an acute problem. Machine data settings can be made to exclude sum offsets
from a data backup (settings can be made separately for "setup offsets" and "sum offsets
fine").
Note
Sum offsets behave in the same way as D compensations with reference to block search
and REPOS. The behavior on Reset and PowerOn can be defined by machine data.
If the setting of the following machine data indicates that the last active tool compensation
number (D) is to be activated after PowerOn, the last active DL number is then no longer
active:
MD20110 $MC_RESET_MODE_MASK (definition of initial control system settings after
RESET/TP-End)
2.9.4

Examples

Example 1
That no compensation and no sum offset will come into effect must be defined during tool
change via the machine data:
• MD20270 $MC_CUTTING_EDGE_DEFAULT=0 (Basic setting of tool cutting edge without
• MD20272 $MC_SUMCORR_DEFAULT=0 (default setting sum offset without program).

; Tool number 5 is loaded - no compensation active.
; Compensation D1 + sum offset 3 of D1 are activated.
; Compensation D1 + sum offset 2 are activated.
; Sum offset deselection, only compensation D1 is now active.
; Compensation D2 is activated - the sum offset is not included in the
compensation.
; Compensation D2 + sum offset 1 are activated.
; Compensation deselection
; No effect - DL2 of D0 is zero (same as programming T0 D2).
