Common Causes

• Programmed cutting speed value exceeds maximum limit of 9999.99 m/min (metric) or 99999.99 inch/min (inch)
• Programmed cutting speed value is below minimum limit of 0.01 m/min (metric) or 0.1 inch/min (inch)
• Incorrect unit selection in program (metric vs inch mismatch with machine settings)
• Decimal point error or typo in S-word command value within NC program
• Machine parameter unit configuration does not match programmed speed values

Troubleshooting Steps

1. 1Review the NC program block referenced in alarm message and verify the S-word (cutting speed) value is within valid range: 0.01-9999.99 m/min for metric or 0.1-99999.99 inch/min for inch mode
2. 2Confirm machine unit settings match the program unit system via machine parameters or G20/G21 commands in the program
3. 3Check for decimal point placement errors or typos in the S-word command; correct the value and reload the program
4. 4If speed conversion between unit systems is required, recalculate and verify the converted value falls within the appropriate range before program restart
5. 5Clear alarm and test with a corrected program block or manually enter a valid cutting speed command to verify system response
