What it means
F01072 tells you that the memory card has been restored from its backup copy. The Control Unit (CU) was switched off while data were being written to the memory card, and the interrupted write left the visible partition of the card defective. When the Control Unit was switched on again, the data from the non-visible partition (the backup copy) were written back to the visible partition — this fault reports that restoration.
Why it appears
- The Control Unit was switched off while the drive was writing data to the memory card, so the visible partition of the card became defective.
What to check
- Check that the firmware and the parameterization of the drive are up-to-date.
Acknowledging and restarting
Acknowledge the fault immediately; clearing the message does not require switching the Control Unit off and on again. The fault does not force any automatic reaction of the drive, so the operating state is not changed by the fault itself — once the firmware and parameterization have been checked, acknowledge the message and it is cleared.
What differs between the drive families
Straight from the manuals' own fields — F01072 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | IMMEDIATELY | General drive fault (19) | Control Unit (CU) | SINAMICS S120, S150 List Manual · p. 2575 |
| G130, G150 | NONE | IMMEDIATELY | General drive fault (19) | Control Unit (CU) | SINAMICS G130, G150 List Manual · p. 1388 |
| G120 | NONE | IMMEDIATELY | General drive fault (19) | — | SINAMICS G120 · p. 830 |

Questions technicians ask
What does SINAMICS fault F01072 mean?
The drive reports that the memory card has been restored from its backup copy. This happened because the Control Unit was switched off during a write access to the card, which left the visible partition defective; on the next power-up the data were copied back from the non-visible (backup) partition.
How do I clear fault F01072?
Check that the firmware and the parameterization are up-to-date, then acknowledge the fault immediately. No power-down of the Control Unit is needed to clear the message.
Does fault F01072 stop the drive?
No. The fault does not trigger any automatic reaction, so the drive does not change its operating state — the message only reports that the memory card was restored from the backup copy.
Why was the memory card of my SINAMICS restored from the backup?
Because the Control Unit was switched off while data were being written to the memory card. The interrupted write left the visible partition defective, and the drive rebuilt it from the backup partition when it was switched on again.
