Your machine tool builder can also define a tool-
change macro for the
Test Run operating mode.
This macro will simulate the exact behavior of the
machine. Refer to your machine manual.
Execute test run
If the central tool file is active, a tool table must be
active (status S) to conduct a test run. Select a tool
table via the file manager in the
Test Run mode of
operation.
For turning tools you can select a turning tool table
with the file extension .trn, compatible with the
selected tool table. This means that the turning tools
must match in both selected tables.
You can select any preset table (status S) for the test run.
After
RESET + START, line 0 of the temporarily loaded preset
table automatically displays the momentarily active datum from
Preset.pr (execution). Line 0 is selected when starting the test run
until you define another datum in the NC program. All datums from
lines > 0 are read by the control from the selected preset table of
the test run.
With the
BLANK IN WORK SPACE function, you activate a
workspace monitor for the test run, see "Showing the workpiece
blank in the working space ", page 558.
Select the Test Run operating mode
Call the file manager with the PGM MGT key and
select the file you wish to test
The TNC then displays the following soft keys:
Soft key Functions

Test each program block individually
Halt test run (soft key only appears once you
have started the test run)
You can interrupt the test run and continue it again at any point
— even within a fixed cycle. In order to continue the test, the
following actions must not be performed:
Selecting another block with the arrow keys or the GOTO key
Making changes to the program
Selecting a new program
