What it means
F37860 reports a DRIVE-CLiQ communication error from the HF Damping Module to the Control Unit (CU). A telegram exchanged between the module and the CU is defective. The drive stores the component number and the fault cause in the message value, so the affected link and the kind of defect can be read out directly.
Why it appears
- Defective DRIVE-CLiQ telegrams between the HF Damping Module and the Control Unit — this is the only cause the manual names for this fault; the message value identifies the exact defect (see the decoding below).
What to check
- Carry out a POWER ON (switch-off/switch-on).
- Check the electrical cabinet design and the cable routing for EMC compliance.
- Check the DRIVE-CLiQ wiring, for example for an interrupted cable or poor contacts.
Reading the message value
The message value carries two items, coded as 0000yyxx hex: yy is the component number, xx is the fault cause. The manual gives the fault cause these meanings:
- 1 to 6 (01 to 06 hex): a defective telegram — checksum error (CRC error); the telegram is too short or too long against the length byte or the receive list; the length, the type or the power unit address of the receive telegram does not match the receive list.
- 9 (09 hex): the component involved signals that the supply voltage has failed.
- 16 to 22 (10 to 16 hex): the receive telegram arrives too early, on its own or combined with the defects above.
- 25 (19 hex): the error bit in the receive telegram is set and the telegram arrives too early.
Parameters the manual names
- r0949 (fault value): holds the coded message value of this fault — split 0000yyxx hex into component number (yy) and fault cause (xx) to see which link failed and why.
- r2124 (alarm value): named by the manual together with r0949 as the register in which the coded component number and fault cause of this message are read out.
Acknowledging and restarting
Acknowledge the fault immediately. The prescribed remedy begins with a POWER ON (switch-off/switch-on); if the telegram error persists, work through the EMC and DRIVE-CLiQ wiring checks above before returning the drive to service.
The same on every family

Questions technicians ask
What does fault F37860 on a SINAMICS S120 mean?
It reports a DRIVE-CLiQ telegram error from the HF Damping Module to the Control Unit. The message value names the component number and the fault cause.
How do I clear F37860?
Acknowledge the fault immediately and carry out a POWER ON (switch-off/switch-on). If it recurs, check the cabinet design and cable routing for EMC compliance and inspect the DRIVE-CLiQ wiring for interrupted cables or poor contacts.
Where can I read the fault cause of F37860?
In the fault value r0949 or the alarm value r2124. The value is coded 0000yyxx hex: yy is the component number and xx the fault cause.
What does fault cause 09 hex in F37860 mean?
That the DRIVE-CLiQ component involved has signalled to the Control Unit that the supply voltage has failed.
