What it means
F30664 is raised when an error occurs while the drive is booting. The manuals describe the code identically across the SINAMICS families; on the G120C and G115D it is listed under the title CU power up aborted
, which points to the CU whose power-up was aborted. The fault carries a value in r0949 that the manual reserves for internal Siemens troubleshooting, so no more detailed description of the error is published.
Why it appears
- An error occurred while the drive was booting. The manual names no further cause: the stored fault value is intended only for internal Siemens troubleshooting.
What to check
- Carry out a POWER ON — switch the drive off and then on again.
- Upgrade the drive firmware to a later version.
- If the fault persists, contact Technical Support.
Reading the message value
- The drive stores the fault value of F30664 in r0949; interpret the value hexadecimal.
- No decoding is published — the manual states
Only for internal Siemens troubleshooting
.
Parameters the manual names
- r0949 — fault value of this message; read it hexadecimal. For F30664 it serves internal Siemens troubleshooting only and gives the user no further information.
Acknowledging and restarting
F30664 is acknowledged with a POWER ON: switch the drive's power supply off and back on. While the fault is active the drive coasts down (OFF2) and will not restart until this power cycle has been carried out and the fault has cleared.
What differs between the drive families
Straight from the manuals' own fields — F30664 is not described identically everywhere.

Questions technicians ask
What causes fault F30664 in SINAMICS drives?
The drive raised the code because an error occurred while it was booting. The manual names no more specific cause; the accompanying fault value is reserved for internal Siemens troubleshooting.
How do I reset F30664?
Only by a POWER ON — switch the drive off and back on again. If the fault comes back, upgrade the firmware to a later version and then contact Technical Support.
Why does my G120C show 'CU power up aborted' instead of 'Error while booting'?
It is the same code, F30664. On the G120C and G115D the manual lists it as 'CU power up aborted', meaning the error occurred while the CU was booting.
Can I decode the fault value of F30664 in r0949?
No. The drive stores the value hexadecimal, but the manual states it is only for internal Siemens troubleshooting and publishes no decoding.
