What causes Siemens SINUMERIK alarm 61324?

Invalid or corrupted values in the 6th position of _KNUM parameter. Incompatible _MVAR parameter settings that conflict with _KNUM configuration. Incorrect tool offset or tool compensation table entries referenced by _KNUM. Memory corruption or failed parameter backup/restore operation. Mismatched parameter values between active cycles and stored _KNUM configuration.

How do I fix Siemens SINUMERIK alarm 61324?

1. Access the alarm log and note the specific channel and block number where the alarm occurred; cross-reference with the active cycle program 2. Retrieve and verify all values in _KNUM parameter, paying special attention to the 6th position entry; compare against valid parameter range documentation 3. Inspect _MVAR parameter settings for conflicts or invalid entries that may interact with the flagged _KNUM position 4. Clear the alarm, perform a parameter backup, then re-enter or restore _KNUM and _MVAR from a known good backup if available 5. Re-run the triggering cycle (CYCLE974, CYCLE977, CYCLE978, CYCLE979, CYCLE994, CYCLE998, or CYCLE114) to confirm the alarm does not recur
