W1: Tool offset
2.15 Sum and setup offsets
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 Power On 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number (D) is to be activated after Power On, the last active DL number is then no longer active:
MD20110 $MC_RESET_MODE_MASK (definition of control default settings after reset / part
program end)
2.15.4

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
programming)
● MD20272 $MC_SUMCORR_DEFAULT=0 (default setting sum offset without program).

Example 2
During tool change it has to be defined that offset D2 and sum offset DL=1 are activated via the
machine data:
198
; 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).
