4.6 Fine tool offset
The limit values of the tool fine correction are contained in the display machine
data MD 9450: WRITE_TOA_FINE_LIMIT.
When entering the tool wear fine, the difference between the previous value and
the new value may not exceed the limit entered here.
MD 9450 can be changed only when the display machine data MD 9202:
USER_CLASS_TOA_WEAR contains a valid protection level.

4.7 Making tool offset active immediately
The display machine data MD 9440: ACTIVATE_SEL_USER_DATA can be used
to ensure that the active tool offset is activated as soon as the parts program is in
the "Reset" or "Stop" state.
When the function is used in the reset state, the channel-specific machine data
MD 20110: RESET_MODE_MASK Bit 0 = reset mode must be set appropriately.
Then the tool offset is not reset on a reset.

4.8 Selecting tools via a D number (flat D no.)
The general machine data MD 18102: TYPE_OF_CUTTING_EDGE can be used to
activate the "flat D number management”.
Value = 0 NCK manages the T and D numbers = default setting
Value = 1 Only tools with the D number structure can be selected.
The D number can be assigned just once per tool, i.e., each D number stands for
one and no more than one offset data block.
