Identify the line number where the alarm occurred and note the specific offset command (G43 H__, G41 D__, etc.).

Check parameters 6001-6004 (mill) or 5001-5004 (lathe) to verify maximum offset memory allocation for tool length, cutter compensation, and geometry offsets.

Compare the offset number called in the program against the maximum available offsets shown in parameters.

Either reduce the offset number in the program to stay within range, or increase the offset memory allocation in parameters if control memory permits.

Changing offset memory parameters may require control restart and could affect existing offset data.

Review the program line at the alarm location for the H, D, or T address format.

Verify the offset number contains only whole positive integers with no decimal points, spaces, or special characters (e.g., H50.5 or H-10 would be invalid).

Check for unintended macro variable substitution that may be passing an out-of-range or invalid value to the offset address.

Correct the offset format to use only valid integer values within the permitted range and re-run the program.

Check if the alarm occurs on a G54.1 P__ command and note the P value specified.

Verify parameter 6038 to confirm the maximum number of extended work coordinate systems available (typically 48, 96, 198, or 300 depending on control model).

Ensure the P value does not exceed the configured maximum or the control's hardware limitation for your specific Fanuc model.

Modify the program to use a valid P value within range, or adjust parameter 6038 if additional extended offsets are needed and available.

Verify control memory capacity before increasing extended offset quantity.
