Note
The PRESET/DRF offset is not visible in the actual value display.
The software limit switches and the working area limitation act as in the
original coordinate system, i.e. they are not offset.
Note
The PRESET offset can only be entered when all mode groups are in the
RESET state.
Input a new actual value. The actual value memories of all axes present can be
preset.
The presetting allows the control to calculate a PRESET offset which is
displayed on the screen in the input window PRESET/DRF.
Optionally, a tool offset can be included in the calculation of PRESET offset.
Enter the tool offset data (correction number, correction direction and
identifier) in front of "Set actual value".
When calculating the tool length compensation the identifier must be entered.
Generally, the values 2 or 3 are entered here. Tool length compensations P2 or
P3 are then calculated in the offset (see PARAMETER area).
The value then input is transferred to the actual value memory, taking account
of the tool offset.
• The machine area has been selected.
