What it means
F30649 reports an internal error inside the Safety Integrated software. On drives where the function runs in the Motor Module or Hydraulic Module (S120, S150, and likewise the G130 and G150 power unit), the manual locates the error in monitoring channel 2. On the G120 the same code stands for an internal error of the Safety Integrated software on processor 2. Independently of the family, the fault puts the converter into a STOP A that cannot be acknowledged.
Why it appears
- An internal error has occurred in the Safety Integrated software in monitoring channel 2 — the wording the manual uses for the Motor Module/Hydraulic Module and for the G130/G150 power unit.
- On the G120 the manual words the same condition as an internal error in the Safety Integrated software on processor 2.
What to check
- Carry out a POWER ON (switch-off/switch-on); on a Motor Module/Hydraulic Module drive this covers all components.
- Re-commission the Safety Integrated function and carry out another POWER ON.
- On a Motor Module/Hydraulic Module drive: upgrade the Motor Module/Hydraulic Module software.
- If the error persists, contact Technical Support.
- Replace the hardware the manual names for your family: the Motor Module/Hydraulic Module, or the Control Unit on the G120.
Reading the message value
- The message value is a placeholder; the concrete fault value is stored in r0949 and is interpreted hexadecimal.
- For this fault the value is meant
Only for internal Siemens troubleshooting
— the manual prints no bit decoding for the service technician. - Abbreviations the manual decodes with this entry: MM = Motor Module, SI = Safety Integrated.
Parameters the manual names
- r0949 — displays the fault value that accompanied F30649 (interpret hexadecimal); per the manual it serves only internal Siemens troubleshooting, so it gives no additional on-site diagnosis.
Acknowledging and restarting
A normal acknowledgement does not clear this fault: the manual notes that the resulting STOP A cannot be acknowledged. Switch the converter off and on again (POWER ON) instead. Should F30649 reappear, re-commission the Safety Integrated function, power down and up once more, and then work through the remaining remedy steps in the checks above.
What differs between the drive families
Straight from the manuals' own fields — F30649 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY (POWER ON) | Hardware/software error (1) | Power Module | SINAMICS S120, S150 List Manual · p. 2981 |
| G130, G150 | OFF2 | IMMEDIATELY (POWER ON) | Hardware/software error (1) | Power Module | SINAMICS G130, G150 List Manual · p. 1681 |
| G120 | OFF2 | IMMEDIATELY (POWER ON) | Hardware/software error (1) | — | SINAMICS G120 · p. 921 |
The drives this code lives on
F30649 is described for G120, G130, G150, S120, S150. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does fault F30649 mean on a SINAMICS drive?
It reports an internal software error in the Safety Integrated software: in monitoring channel 2 on Motor Module/Hydraulic Module drives and the G130/G150, and on processor 2 on the G120. The converter goes to a STOP A that cannot be acknowledged.
How do I clear F30649?
Carry out a POWER ON (switch the converter off and on). If the fault returns, re-commission the Safety Integrated function and carry out another POWER ON.
Do I have to replace hardware after F30649?
Only if the POWER ON and the re-commissioning of the Safety Integrated function do not help. On a Motor Module/Hydraulic Module drive upgrade the module software first and contact Technical Support; the last step is replacing the Motor Module/Hydraulic Module or, on the G120, the Control Unit.
What does the fault value of F30649 in r0949 tell me?
It is a hexadecimal value that the manual reserves for internal Siemens troubleshooting; no bit decoding is printed, so it gives the technician no further clue.
