Common Causes

• D offset number referenced in program does not exist in the tool offset table
• Tool offset table not properly loaded or initialized in the NC system
• Mismatch between programmed D number and available D offsets for the specified T number
• Corrupt or incomplete tool offset data in NC memory
• Incorrect D number syntax or out-of-range value in NC program

Troubleshooting Steps

1. 1Verify the D number called in the program exists in the active tool offset table; cross-reference against the offset management screen in the NC interface
2. 2Check if flat D number function is active and confirm T=1 is properly configured with corresponding D offsets when this mode is enabled
3. 3Load or reload the tool offset table from backup or re-enter missing D offset entries; confirm all D numbers match program requirements
4. 4Review the NC program syntax for the tool call statement; ensure D number is within valid range (typically 0-32000 depending on system configuration) and properly formatted
5. 5Perform an NC system reset and reload tool compensation data; if issue persists, verify NC memory integrity and consider restoring from known good backup
