9.8 Deleting a compile cycle

9.8 Deleting a compile cycle
If a loaded compile cycle is to be completely deleted in the control, it is not enough to only
delete the corresponding ELF file. With this procedure, the following data is kept in the
retentive memory of the control:
• Activation data: $MN_CC_ACTIVE_IN_CHAN_<identifier>[n]
• Function-specific machine data
Execution
Perform the following actions to delete a compile cycle:
1. Create an NC archive without compile cycles:
Operating area: "Commissioning" > "ETC" key > "Commissioning archive" > "Creating a
commissioning archive" > "OK" >
-
-
2. Delete the compile cycle:
:Operating area: "Commissioning" > "System data" in the directory: NC data > "Compile
cycles" > File: Select "<Identifier>.ELF" > "Delete"
3. Initiate a power on reset with an NCK general reset (NCK commissioning switch: position
"1"). See:
References:
Commissioning Manual IBN CNC: NCK, PLC, drive; Chapter: General tips > Separate
NCK and PLC general reset > NCK general reset
4. Download the NC archive created under Point 1 into the NCU again.
Operating area: "Commissioning" > "ETC" key > "Commissioning archive" > "Read-in
commissioning archive" > "OK"
Note
Several loaded compile cycles
If several compile cycles are loaded in the control, when deleting a compile cycle according
to the process described above, the other compile cycles remain unchanged.
Efficient memory usage
To use the memory resources in the NCK as efficiently as possible, you should only load the
compile cycles (ELF files) that are actually required into the machine.
