Press RESET to clear the alarm, then press PRGRM key and review the current program line displayed on the screen where alarm occurred.

Locate the M98 subprogram call or canned cycle line (G73, G74, G76, G80-G89) and verify the L-word value. Check if it exceeds 9999 (or 999 on older controls).

Navigate to SYSTEM > PARAM and check parameter 3117 (subprogram nest level) and parameter 3107 (max. repetition count setting) if available on your control series to verify system limits.

Edit the program and reduce the L-word repeat count to a valid range (1-9999 or 1-999). If more repetitions are needed, restructure the program using nested subprograms or main program loops.

Ensure program logic remains correct after modifying repeat counts. Test in single block mode after correction.

Press RESET and review the program line at alarm occurrence. Check for L0 or negative L-values in M98 calls or canned cycles.

If L0 was intentional (attempting to skip execution), remove the entire program block or use conditional statements (IF/GOTO) with macro programming if parameter 6001#0=1 enables custom macros.

If using variable programming (#500-#999 range), verify the variable assigned to the L-word contains a positive value. Navigate to SYSTEM > MACRO > VARIABLE to check current variable values.

Correct the L-value to a minimum of L1 or restructure program logic to avoid calling the subprogram/cycle when not needed.

Variable-based repeat counts must be validated before use to prevent runtime errors.

Press RESET and navigate to PRGRM to examine the alarmed program line. Look for decimal points in the L-word specification (e.g., M98 P1000 L5.5).

If using macro variables for the L-value, check SYSTEM > MACRO > VARIABLE to verify the variable contains an integer. Use ROUND, FIX, or FUP functions in macro code to ensure integer values.

Verify parameter 3450 (decimal point programming setting) has not caused unintended decimal interpretation. Standard setting is 0 for most applications.

Do not change parameter 3450 without understanding impact on all program addresses system-wide.

Correct the L-word to contain only integer values with no decimal point. Re-validate program syntax using the program check function if available on your control.
