Check the T-code in the program line where the alarm occurred and note the tool number and group number being called.

Access the Tool Life Management screen (OFFSET/SETTING - Tool Life Management) and verify the tool group exists and has available capacity.

Review parameters 6800-6809 to confirm maximum number of tool groups and tools per group settings match your program requirements.

Changing these parameters may require a control reboot and could affect existing tool life data

Correct the program to reference valid tool group numbers within the configured range, or expand the tool life table capacity via parameters if needed.

Locate any G10 L3 commands in the program and verify the format matches: G10 L3 P[group] Q[tool number] R[life value] [optional L-type].

Confirm the P address (group number) and Q address (tool position) are specified with valid positive integers within configured limits.

Check parameter 6802 (tool life counter type) to ensure the R value format matches the configured type: 0=count, 1=time in minutes, 2=time in seconds.

Verify bit 0 of parameter 6800 (TLF) is set to 1 to enable tool life management function, and bit 6 (TLC) matches your count-up/count-down requirement.

Parameter 6800 is a critical setting - document current value before making changes

Check if tool life management option is enabled on your control by accessing System Config screen (typically under SYSTEM softkey) and verifying TLC/TLM option is present.

Verify parameter 6800 bit 0 (TLF) = 1 to enable tool life function. If disabled, tool life commands in the program will trigger this alarm.

Enabling TLF requires the optional tool life management feature to be installed on your control

Review parameter 6801 (number of tool groups) and 6802 (number of tools per group) to ensure values are greater than zero and match your application needs.

If tool life option is not available or cannot be enabled, remove or comment out all G10 L3 commands and tool life related code from the program.
