Cycle and highlighted block
Save the active cycle and highlighted block. Compare units, depth, references and tool data with the drawing and cycle version. If the message follows a program change, keep the previous copy for comparison.

HEIDENHAIN alarms: TNC model and full message
A useful search starts with the TNC model and full message. Cycle, programming and diagnostics documentation differs between TNC 320, 620, 640, iTNC 530 and TNC7. This index organises catalogue messages, but a matching number does not guarantee the same explanation across every version.
Referencing and position measurement
If an axis is indicated, record when the message appears and whether it affects referencing. Do not immediately attribute it to a scale or encoder without checking the message and control conditions. Measurement-system work must follow the machine procedure.
Documentation by version
The HEIDENHAIN portal separates manuals by control and software version. Find that combination and the builder’s documents for machine messages. Provide the exact wording and event sequence when contacting maintenance.
Official documentation
Choose the manual matching your control series, software version and machine builder. A support portal is a starting point; it does not establish applicability to every model.
Alarms by control brand
Every control numbers and describes its alarms in its own way. Go into the brand of your machine to see the full list with the meaning of each code.
