  • Tool management parameters not synchronized with active tool offset memory

Troubleshooting Steps

  2. 2Check parameter _TNAME and confirm the specified tool name exists in the tool management database; cross-reference tool catalog
  3. 3Review the measuring cycle call sequence to ensure tool selection occurs before cycle execution
  4. 4Inspect tool management configuration in machine parameters to confirm it is properly enabled and linked to active tool offset memory
  5. 5Clear any cached tool data and perform a tool management database reload; verify tool offset table contents match defined tools
