What it means
F06907 is raised when the temperature sensor connected to the braking resistor signals an overtemperature. The Braking Module is still active at this point. This is the early stage of the condition: if the overtemperature persists for more than 60 s, the drive outputs F06908 and switches the Braking Module off. The manual cross-references r3687, the digital Braking Module pre-alarm overtemperature signal, for this fault.
Why it appears
- The temperature sensor wired to the braking resistor reports an overtemperature.
What to check
- Reduce the temperature at the sensor while the Braking Module is still active — if the overtemperature persists for more than 60 s, the drive outputs F06908 and switches the Braking Module off.
- Check the temperature sensor connection.
Parameters the manual names
- r3687 — binector output (BO) "Digital Braking Module pre-alarm overtemperature": the overtemperature pre-alarm signal of the digital Braking Module, which the manual cross-references for this fault.
Acknowledging and restarting
Reduce the temperature at the sensor and check the temperature sensor connection, then acknowledge the fault; the drive can then be restarted. If the overtemperature has not actually been cleared, the drive outputs F06908 after 60 s and switches the Braking Module off, so the temperature and the sensor connection must genuinely be put right before the restart.
The same on every family
Every manual that describes F06907 gives it the same reaction, acknowledgement and message class.

| S120, S150 | OFF2 (NONE, OFF1) | IMMEDIATELY | Braking Module faulted (14) | None | SINAMICS S120, S150 List Manual · p. 2775 |

Questions technicians ask
What does fault F06907 mean on a SINAMICS drive?
The temperature sensor connected to the braking resistor has signalled an overtemperature. The Braking Module is still active when this fault appears.
What happens if F06907 persists?
If the overtemperature persists for more than 60 s, the drive outputs F06908 and switches the Braking Module off.
How do I clear fault F06907?
Reduce the temperature at the sensor and check the temperature sensor connection, then acknowledge the fault and restart the drive.
Which parameter is linked to F06907?
r3687 — the digital Braking Module pre-alarm overtemperature binector output — is the signal the manual cross-references for this fault.
