A02096 — MTrace 0: cannot be saved

The drive cannot save the measurement results of a multiple trace on the memory card (trace recorder 0). The multiple trace is therefore not started at all or is canceled while it runs. The message value (%1) carries the alarm value, which the drive also writes to r2124 and which identifies the concrete reason for the alarm.

• The memory card cannot be accessed — the card is not inserted, or access to it is blocked by a mounted USB drive (alarm value 1).
• The data save operation is too slow — a second trace has completed before the measurement results of the first trace could be saved, or writing the measurement result files to the card is blocked by a parameter save (alarm value 3).
• The data save operation was canceled — for instance, the file required for the data save operation could not be found (alarm value 4).

1. Insert or remove the memory card — the card may be missing, or a mounted USB drive may be blocking access to it.
2. Use a larger memory card.
3. Configure a longer trace time or use an endless trace.
4. Avoid saving parameters while a multiple trace is running.
5. Check whether other functions are presently accessing the measurement result files.

• The alarm value is stored in r2124 and is to be interpreted as a decimal number; the message value %1 contains this value.
• 1 — memory card cannot be accessed: the card is not inserted or is blocked by a mounted USB drive.
• 3 — data save operation too slow: a second trace has been completed before the measurement results of the first trace were able to be saved, or writing the measurement result files to the card is blocked by the parameter save.
• 4 — data save operation canceled: for instance, the file required for the data save operation was not able to be found.

• r2124 — alarm value: read it as a decimal number to see which of the three situations (1, 3 or 4) triggered the alarm.
• p4840 — MTrace cycle number setting: the parameter the manual cross-references for this alarm; it sets the cycle number of the multiple trace.

No acknowledgment is required: the alarm goes away by itself once the measurement results can be saved again — for example after the memory card has been inserted or freed. The multiple trace can then be started again.
