What it means
F07810 tells you that the drive has read the EEPROM of the power unit and found no rated data stored there. The EEPROM is the memory in which the power unit's rated data are kept; when the drive looks for them and finds none, it raises this fault. The manuals for the G120, G120XA, G130, G150, S120 and S150 print the same cause and the same remedy for it.
Why it appears
- No rated data are stored in the EEPROM of the power unit — every manual that describes F07810 gives this single cause.
What to check
- Call up p0205 and the rated-data parameters r0206, r0207, r0208 and r0209 — the references the manual attaches to this fault. They show the power unit's rated power, rated current, rated line supply voltage and maximum current, the data that are missing here.
- Replace the power unit.
- If a replacement is not an option, inform Siemens Customer Service.
Parameters the manual names
- p0205 — power unit application; the manual lists it among the references for this fault.
- r0206 — read the rated power unit power here.
- r0207 — read the rated power unit current here.
- r0208 — read the rated power unit line supply voltage here.
- r0209 — read the power unit maximum current here.
Acknowledging and restarting
Acknowledge the fault immediately. Acknowledging does not put the missing rated data back into the EEPROM: the remedy the manual gives is to replace the power unit or to inform Siemens Customer Service.
What differs between the drive families
Straight from the manuals' own fields — F07810 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |

| S120, S150 | NONE | IMMEDIATELY | Hardware/software error (1) | Power Module | SINAMICS S120, S150 List Manual · p. 2865 |
| G130, G150 | NONE | IMMEDIATELY | Hardware/software error (1) | Power Module | SINAMICS G130, G150 List Manual · p. 1597 |
| G120 | NONE | IMMEDIATELY | Hardware/software error (1) | — | SINAMICS G120 · p. 882 |
| G120XA | NONE | IMMEDIATELY | — | — | SINAMICS G120XA PN converter · p. 1134 |

Questions technicians ask
What does fault F07810 mean on my SINAMICS drive?
The drive has found no rated data in the EEPROM of the power unit. The manuals print the same cause for every family that describes the code, from G120 to S150.
Can F07810 be cleared without replacing the power unit?
The fault is acknowledged immediately, but acknowledging does not write the missing rated data into the EEPROM. The manual's remedy is to replace the power unit or to inform Siemens Customer Service.
Which parameters belong to F07810?
p0205 and the rated-data parameters r0206, r0207, r0208 and r0209. They show the power unit's rated power, rated current, rated line supply voltage and maximum current.
