CRC sum for control data is incorrect. Often requires service agency intervention. Processor check error 4: Crosstalk of data in RAM memory. Processor check error Q: A required CPU (control loop or geometry) is not ready. Switch the control off and back on. 2.

Write down the exact code text and any accompanying numbers. Note what block number the NC program stopped on.
❌ – The company integrates error explanations into the iTNC 530 User’s Manual and Technical Manual , not a standalone “error code book”. ❌ Machine-specific variations – A builder (e.g., DMG, Haas, Mazak) may override or add proprietary errors – those won’t appear in generic lists. ❌ Incomplete or outdated – Free online lists often miss rare or newer errors (firmware-dependent). ❌ PLC errors are cryptic – Many “PLC error xxxx” require access to the machine’s ladder logic – generic lists won’t help much.
