What it means
F37837 is raised when the drive detects a fault on the DRIVE-CLiQ component concerned — the HF Damping Module. The manual notes: Faulty hardware cannot be excluded.
Which component reported the fault and why it did so is coded in the message value, which you can read in r0949 or r2124; the decoding is listed below.
Why it appears
- A fault was detected on the DRIVE-CLiQ component concerned — the HF Damping Module, so the component itself may be faulty.
- Depending on the coded fault cause, it is an error in the telegram header, or a receive or send error in which the telegram buffer memory contains an error.
What to check
- Check the DRIVE-CLiQ wiring (interrupted cable, contacts, ...).
- Check the electrical cabinet design and cable routing for EMC compliance.
- If required, use another DRIVE-CLiQ socket (p9904).
- Replace the component involved.
Reading the message value
- Message value: Component number: %1, fault cause: %2.
- The individual information is coded in the message value (r0949/r2124) as 0000yyxx hex: yy = component number, xx = error cause.
- Fault cause 32 (= 20 hex): error in the telegram header.
- Fault cause 35 (= 23 hex): receive error — the telegram buffer memory contains an error.
- Fault cause 66 (= 42 hex): send error — the telegram buffer memory contains an error.
- Fault cause 67 (= 43 hex): send error — the telegram buffer memory contains an error.
Parameters the manual names
- r0949 (fault value): read the coded component number and fault cause of F37837 here.
- r2124 (alarm value): the same coding of component number and error cause can also be read here (message value r0949/r2124).
- p9904 (Topo_compare ackn): acknowledge the topology differences if the HF Damping Module is connected to another DRIVE-CLiQ socket.

Questions technicians ask
What does fault F37837 mean on a SINAMICS drive?
A fault was detected on the DRIVE-CLiQ component concerned, the HF Damping Module. The manual states that faulty hardware cannot be excluded.
How do I fix fault F37837?
Check the DRIVE-CLiQ wiring (interrupted cable, contacts), check the electrical cabinet design and cable routing for EMC compliance, and if required use another DRIVE-CLiQ socket (p9904). If the fault remains, replace the component involved.
How is the fault cause of F37837 coded?
The message value (r0949/r2124) has the form 0000yyxx hex, where yy is the component number and xx the error cause. Fault cause 32 (20 hex) is a telegram header error, while 35, 66 and 67 are receive or send errors in which the telegram buffer memory contains an error.
