What it means
F30899 reports that the power unit has raised a fault that the firmware on the Control Unit cannot interpret — the Control Unit receives a fault number for which it has no description. According to the manual this can occur when the firmware on the power unit is more recent than the firmware on the Control Unit. Depending on how the drive is configured, the same condition can also be issued as an alarm (A) or with no reaction (N) instead of a fault.
Why it appears
- A fault occurred on the power unit that the firmware on the Control Unit cannot interpret.
- This can be the case when the firmware on the power unit is more recent than the firmware on the Control Unit.
What to check
- Read the unknown fault number from r0949; the manual specifies interpreting this value as decimal. It is the number behind the message value "New message: %1".
- Identify the new fault: the manual notes,
If required, the significance of this new fault can be read about in a more recent description of the Control Unit
. - Compare the firmware levels: r0128 shows the power unit firmware version and r0018 shows the Control Unit firmware version.
- Then apply one of the two remedies the manual gives: replace the firmware on the power unit with an older firmware version (the installed version can be read in r0128), or upgrade the firmware on the Control Unit (installed version in r0018).
Reading the message value
- The message value reads "New message: %1".
- Fault value in r0949, to be interpreted as decimal: it contains the fault number — the number of the power-unit fault that the Control Unit firmware cannot interpret.
Parameters the manual names
- r0949 — fault value of this message: read the unknown fault number here and interpret it as decimal.
- r0128 — power unit firmware version: shows the firmware level on the power unit, relevant before replacing it with an older version.
- r0018 — Control Unit firmware version: shows the firmware level on the Control Unit, relevant before performing the upgrade.
Acknowledging and restarting
Resolve the firmware situation first (see the steps above). The fault can then be acknowledged immediately; POWER ON also serves as an acknowledgement. When the condition is present as an alarm or as a message without reaction (A or N variant), no acknowledgement is required. Once the fault is cleared, the drive can be restarted.
What differs between the drive families
Straight from the manuals' own fields — F30899 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: NONE (OFF1, OFF2) Servo: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2) Vector: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2) Hla: NONE (OFF1, OFF2, OFF3, STOP2) | — | Power electronics faulted (5) | Power Module | SINAMICS S120, S150 List Manual · p. 3022 |
| G130, G150 | Vector: NONE (IASC/DCBRK, OFF1, OFF2, OFF3, STOP2) Infeed: NONE (OFF1, OFF2) | IMMEDIATELY (POWER ON) | Power electronics faulted (5) | Power Module | SINAMICS G130, G150 List Manual · p. 1713 |

Questions technicians ask
What does fault F30899 mean on a SINAMICS G130 or S120?
The power unit has reported a fault number that the firmware on the Control Unit cannot interpret. This usually happens when the firmware on the power unit is more recent than the firmware on the Control Unit.
How do I fix F30899?
Read the reported fault number in r0949 (interpret it as decimal), then either replace the power unit firmware with an older version (version in r0128) or upgrade the Control Unit firmware (version in r0018). The fault is acknowledged immediately; POWER ON also acknowledges it.
Where can I find the meaning of the unknown fault number?
The manual states that the significance of the new fault can be read about in a more recent description of the Control Unit. The number itself is stored in r0949.
Can F30899 appear as an alarm instead of a fault?
Yes. Depending on the drive configuration, the same condition can also be issued as an alarm (A) or with no reaction (N) instead of a fault, and then no acknowledgement is required.
