What it means
The HF Damping Module keeps data in an EEPROM. Fault F37052 is raised when this data cannot be used: either the data read in from the HF Damping Module is inconsistent, or the data does not fit the firmware of the HF Damping Module. The drive stores the exact reason as a fault value in r0949, which the manual says to interpret hexadecimal.
Why it appears
- The EEPROM data read in from the HF Damping Module is inconsistent (fault value 0).
- The EEPROM data is not compatible with the firmware of the HF Damping Module (fault value 1).
- Additional fault values exist, but these are reserved for internal Siemens troubleshooting.
What to check
- Read the fault value in r0949 (interpret hexadecimal) to determine which of the two cases applies.
- For fault value = 0: replace the HF Damping Module or update the EEPROM data.
- For fault value = 1: if necessary, upgrade the firmware to a later version.
Reading the message value
- 0: The EEPROM data read in from the HF Damping Module is inconsistent.
- 1: EEPROM data is not compatible to the firmware of the HF Damping Module.
- Additional values: Only for internal Siemens troubleshooting.
Parameters the manual names
- r0949 — fault value of this fault; read it (interpret hexadecimal) to decide between the two remedies above.
Acknowledging and restarting
This fault is acknowledged with a POWER ON: the drive must be switched off and back on before the fault clears. Acknowledging it from the operator panel or the commissioning tool alone does not remove the fault.
The same on every family
Every manual that describes F37052 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | POWER ON | Hardware/software error (1) | None | SINAMICS S120, S150 List Manual · p. 3266 |

Questions technicians ask
What does fault F37052 mean on a SINAMICS S120 or S150?
It reports an EEPROM data error of the HF Damping Module: the data read in from the module is either inconsistent (fault value 0) or not compatible with the module firmware (fault value 1).
How can I see which cause triggered F37052?
Read the fault value in r0949 and interpret it hexadecimal. Value 0 means the EEPROM data is inconsistent; value 1 means the data does not match the firmware of the HF Damping Module.
How do I fix F37052?
For fault value 0, replace the HF Damping Module or update the EEPROM data; for fault value 1, upgrade the firmware to a later version if necessary. Afterwards the fault is cleared by a POWER ON.
Can F37052 be acknowledged without switching the power off?
No. The manual assigns POWER ON as the acknowledgment, so the drive has to be powered off and on again to clear the fault.
