Press OFFSET/SETTING button, select TOOL GEOM or TOOL OFFSET screen. Check the tool figure number (FIG or SHAPE column) for the active tool in the program.

Navigate to SYSTEM > PARAM and check parameter 5003 (tool figure data definition range). Verify the tool figure number is within the defined range (usually 0 to maximum defined figures).

Check parameters 13240-13249 (tool interference check settings) to confirm interference checking is properly configured and tool figure library is properly set.

Correct the tool figure number in the TOOL GEOM screen to a valid predefined figure, or set to 0 if interference check is not required for this tool.

Setting figure to 0 typically disables interference checking for that tool

Access OFFSET/SETTING screen and review all geometry offset values (X, Z, R, Q dimensions depending on machine configuration) for the tool causing the alarm. Look for unusually large values, negative values where not allowed, or zero values where dimensions are required.

Compare geometry data against the tool figure template requirements. Navigate to SYSTEM > PARAM and check parameter 5004 (tool figure data input method) to understand the expected data format.

Clear suspect geometry data and re-input correct tool dimensions according to the actual tool holder/tool assembly. Verify dimensions match the selected tool figure type (e.g., cylindrical, angular, facing).

Backup tool offset data before clearing using memory card or PMC parameters

Execute a test move in single block mode with interference check active (G22) to verify geometry data is now accepted by the system.

Navigate to SYSTEM > PARAM and verify parameter 5000#0 (tool figure data valid flag) is set to 1. Check parameters 13240#0 (interference check enable) and 13241 (number of tool figures) are correctly configured.

Access the tool figure library definition screen (path varies: SETTING > GRAPHIC > TOOL FIG or similar depending on series). Verify that the figure numbers referenced in your tool offsets have corresponding definitions with complete geometric parameters.

If figure library is corrupted or incomplete, restore from backup or manually redefine tool figures according to machine builder specifications. Consult machine tool builder documentation for standard tool figure definitions.

Incorrect tool figure definitions can cause collisions even if alarm clears

After correcting library definitions, power cycle the CNC (full power OFF/ON) to ensure all interference check data structures are properly initialized.

Ensure all axes are in safe position before power cycle
