There are two ways to run a tool usage test for a pallet file:
If the cursor in the pallet file is on a pallet entry, the control runs
the tool usage test for the entire pallet.
If the cursor in the pallet file is on a program entry, the control
runs the tool usage test only for the selected program.
Using a tool usage test
Before starting a program in the
Program Run, Full Sequence/
Single Block
operating modes, you can check whether the tools
being used in the selected program are available and have sufficient
remaining service life. The control then compares the actual
service-life values in the tool table with the nominal values from the
tool usage file.
Press the

Press the
TOOL USAGE TEST
soft key
The control opens the

pop-up
window indicating the result of the usage test.
Press the
OK

The control closes the pop-up window.

You can query the tool usage test with the
