The control saves the tool usage times in a separate file with the
extension pgmname.H.T.DEP. This file is not visible unless the
machine parameter dependentFiles (no. 122101) is set to MANUAL
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 TOOL USAGE soft key
Press the TOOL USAGE TEST soft key
The control opens the Tool usage test pop-up
window indicating the result of the usage test.
Press the OK soft key
The control closes the pop-up window.
Alternative: Press the ENT key
You can query the tool usage test with the FN 18 ID975 NR1
function.
