Detailed description
2.3 System variables for synchronized actions
Behavior at change of operating mode
The tool length compensation remains active after a change of operating mode. The offset is
executed in all operating modes except JOG and REF.
If a tool length compensation is traversed because of $AA_TOFF[ ] at a change of operating
mode, the operating mode changeover is only carried out after the traversal of the tool length
compensation. Alarm 16907 "Channel %1 action %2 <ALNX> possible only in stop state" is
displayed.
Behavior with REPOS
The tool length compensation is active in
Supplementary conditions
With an existing tool length offset, the following supplementary conditions must be taken into
account:
● A transformation must be switched off with
