Test Run and Program Run
16.4 Test run
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.
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 WORKING SPACE function, you activate working
space monitoring for the test run.
