What it means
F30058 is raised when the feedback signal from the heat sink fan of the power unit signals a fault. The drive therefore suspects that the fan is no longer running properly or can no longer be monitored reliably. Depending on how the drive is configured, the same condition can also be signalled as an alarm or without any reaction.
Why it appears
- The fan is defective.
- The fan is blocked.
- The feedback signal is inaccurate.
- The fan power supply is interrupted — the drive only evaluates this when r0193.13 = 1.
What to check
- Check the heat sink fan and replace it if necessary.
- Check the fan power supply and switch it on if required — this step only applies when r0193.13 = 1.
- On an S120 Combi with a separately driven fan that has a feedback signal, check the fan wiring at X12.2 or X13.2.
- On an S120 Combi with a separately driven fan without a feedback signal, check that instead of the fan feedback signal a connection to ground is established at X12.1/2 or X13.1/2.
Parameters the manual names
- r0193 (Power unit firmware properties 2 / PU FW properties 2): bit 13 shows whether the drive monitors the fan power supply at all — the supply-related cause and the corresponding check only apply when r0193.13 = 1.
Acknowledging and restarting
Acknowledge the fault at the operator panel or in the commissioning tool before restarting the drive. Do not treat a successful acknowledgement as proof that the fan is fixed: if the fault can be acknowledged, this does not necessarily mean that the cause of the fault has been resolved.
It is also possible that the software has switched the fan off and can therefore no longer evaluate the feedback signal — so work through the checks above even when the message clears.
The same on every family
Every manual that describes F30058 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 (NONE, OFF1) | IMMEDIATELY | External measured value / signal state outside the permissible range (16) | Power Module | SINAMICS S120, S150 List Manual · p. 2960 |

Questions technicians ask
What does fault F30058 mean on a SINAMICS drive?
The drive is reporting that the feedback signal from the power unit's heat sink fan signals a fault — typically a defective or blocked fan, an inaccurate feedback signal, or an interrupted fan power supply.
How do I fix fault F30058?
Check the heat sink fan and replace it if necessary, and check the fan power supply and switch it on if required (only monitored when r0193.13 = 1). On an S120 Combi with a separately driven fan with feedback signal, also check the wiring at X12.2 or X13.2.
Why does F30058 come back after I acknowledge it?
Acknowledging does not necessarily mean the cause has been resolved — the software may have switched the fan off and can then no longer evaluate the feedback signal. Work through the checks before trusting a cleared message.
Which terminal wiring is checked for F30058 on an S120 Combi?
With a separately driven fan that has a feedback signal, check the wiring at X12.2 or X13.2. With a separately driven fan without a feedback signal, a connection to ground must be established instead, at X12.1/2 or X13.1/2.
