What it means
F30105 is raised by the power unit (PU): the drive has detected that at least one actual value channel on the Power Stack Adapter (PSA) is supplying an incorrect value. The manuals that describe this code give the same fault text, and the drive's diagnostic parameters show which of the actual value channels are faulty.
Why it appears
- At least one incorrect actual value channel was detected on the Power Stack Adapter (PSA).
- The diagnostic parameters printed with the fault text display which actual value channels are affected.
What to check
- Evaluate the diagnostic parameters listed with this fault; they show which actual value channels are incorrect.
- For every actual value channel found to be incorrect, check the components.
- Replace the component if the check requires it.
Acknowledging and restarting
The drive reacts to this fault with OFF2 and it must be acknowledged immediately. Clear the cause first — read the diagnostic parameters to identify the incorrect actual value channel, then check or replace its component — and acknowledge the fault so the drive can be restarted.
What differs between the drive families
Straight from the manuals' own fields — F30105 is not described identically everywhere.

Questions technicians ask
What does SINAMICS fault F30105 mean?
The power unit has detected that at least one actual value channel on the Power Stack Adapter (PSA) is incorrect. The drive's diagnostic parameters show which channels are affected.
How do I fix fault F30105?
Evaluate the diagnostic parameters, check the components of any incorrect actual value channel and replace them if required. Then acknowledge the fault and restart the drive.
Which drives report F30105?
The manuals describe F30105 with the same text for the G120, G120XA, G130, G150, S120 and S150 power units.
What is the PSA on a SINAMICS power unit?
PSA stands for Power Stack Adapter, the component on which F30105 detected the incorrect actual value channel.
