Navigate to SYSTEM > PARAM and check parameter 13265 (maximum number of tool life management groups). Note the current value (range: 0-512 depending on CNC model and option).

Review the part program for G10 L3 commands or tool group references (H-code or D-code depending on system). Verify the group number does not exceed parameter 13265 value.

If more groups are needed, increase parameter 13265 value (requires parameter write enable bit 0/0 = 1). Power cycle the CNC after changing this parameter.

Changing parameter 13265 may require additional memory allocation. Verify CNC memory capacity before increasing significantly.

If group number is incorrect in program, edit the part program to use valid group numbers (1 through parameter 13265 value). Clear alarm with RESET and restart program.

Navigate to OFFSET SETTING screen and select TOOL LIFE MANAGEMENT button (or press function key depending on CNC series). Review all group numbers in the table for invalid entries (negative numbers, excessively large values).

Check DIAGNOSIS screen number 300-307 for tool life management status data. Look for abnormal group count or data integrity errors.

If corrupted data is found, initialize tool life management data: Set parameter 13290 bit 0 (TLM data clear) = 1, power cycle CNC, then set bit back to 0 and power cycle again.

This will erase all tool life management data. Backup existing data if possible before performing this operation.

Re-enter tool life management group data manually via MDI or restore from known good backup file. Verify parameter 13265 matches the required number of groups.

Navigate to SYSTEM > PARAM and verify parameter 13280 bit 0 (tool life management enable) = 1. Also check parameter 13201 for tool life management type selection (0=type A, 1=type B).

Access SYSTEM > DIAGNOSIS screen and check diagnosis 0 (option list). Verify tool life management option bit is enabled. Cross-reference with the CNC's physical option board or software option key.

If option is not enabled but parameter 13280 bit 0 = 1, set parameter 13280 bit 0 = 0 to disable tool life management functionality. Power cycle CNC and remove tool life management commands from part programs.

Requires parameter write enable. This disables tool life management functionality entirely.

If option should be enabled, contact Fanuc or machine tool builder to verify proper option installation. May require option enablement through software key or hardware installation.
