Datum display
The values shown at the lower left of the screen are
the manually set datums referenced to the machine
datum. They cannot be changed in the menu.
Axis traverse limits for
test run (not TNC 426, TNC 430)
It is possible to define a separate “traverse range”
(switch soft-key row as required) for the test run and
programming graphics after you have activated the
MOD function.
In addition to the axis traverse limits, you can also
define the position of the workpiece datum
referenced to the machine datum.
The tool radius is not automatically
compensated in the axis traverse limit
value.
The traverse range limits and software
limit switches become active as soon as
the reference points are traversed.
