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 594.
Select the Test Run operating mode
Call the file manager with the
PGM MGT key and

Selecting another block with the arrow keys or the
GOTO key
