What it means
F36820 reports a telegram error on DRIVE-CLiQ: a DRIVE-CLiQ communications error has occurred from the Control Unit to the DRIVE-CLiQ Hub Module involved. The message value identifies the affected hub component and the exact telegram fault cause, so read it before you start checking hardware. The manuals describe this fault for the G130, G150, S120 and S150 with essentially the same wording.
Why it appears
- A DRIVE-CLiQ communications error has occurred from the Control Unit to the DRIVE-CLiQ Hub Module involved — this is the one cause both manuals print.
- Which telegram problem actually triggered the fault is told by the fault cause stored in the message value (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 (interrupted cable, contacts, ...).
Reading the message value
- Message value: Component number: %1, fault cause: %2.
- Coding in r0949/r2124: 0000yyxx hex, where yy = component number and xx = error cause.
- Fault cause 1 (= 01 hex): Checksum error (CRC error).
- Fault cause 2 (= 02 hex): Telegram is shorter than specified in the length byte or in the receive list.
- Fault cause 3 (= 03 hex): Telegram is longer than specified in the length byte or in the receive list.
- Fault cause 4 (= 04 hex): The length of the receive telegram does not match the receive list.
- Fault cause 5 (= 05 hex): The type of the receive telegram does not match the receive list.
- Fault cause 6 (= 06 hex): The address of the component in the telegram and in the receive list do not match.
- Fault cause 7 (= 07 hex): A SYNC telegram is expected - but the received telegram is not a SYNC telegram.
- Fault cause 8 (= 08 hex): No SYNC telegram is expected - but the received telegram is one.
- Fault cause 9 (= 09 hex): The error bit in the receive telegram is set.
- Fault cause 16 (= 10 hex): The receive telegram is too early.
Parameters the manual names
- r0949 - fault value: read the message value of this fault here; it holds the 0000yyxx hex coding with the hub component number and the fault cause.
- r2124 - alarm value: the manual names it alongside r0949 as a location where the same coding for this message is stored.
- p9916 - DRIVE-CLiQ data transfer error shutdown threshold slave: the remedy for this fault on the G130 and G150 points to this parameter ('See also: p9916').
Acknowledging and restarting
Once the cause has been rectified, carry out the POWER ON (switch-off/switch-on) from the remedy, acknowledge the fault and restart the drive. How the acknowledgement is performed on your converter is shown with the message data printed alongside this page.
What differs between the drive families
Straight from the manuals' own fields — F36820 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | — | — | Internal (DRIVE-CLiQ) communication error (12) | Terminal Board (TB) | SINAMICS S120, S150 List Manual · p. 3252 |
| G130, G150 | NONE | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Terminal Board (TB) | SINAMICS G130, G150 List Manual · p. 1914 |

Questions technicians ask
What does fault F36820 mean on a SINAMICS drive?
It reports a DRIVE-CLiQ communications error from the Control Unit to the DRIVE-CLiQ Hub Module involved. The message value tells you which hub component is affected and which telegram fault cause occurred.
How do I decode the F36820 fault value in r0949?
The value is coded 0000yyxx hex: yy is the component number and xx is the error cause. For example, 1 (= 01 hex) is a checksum error (CRC error) and 16 (= 10 hex) means the receive telegram was too early.
How do I fix fault F36820?
Carry out a POWER ON (switch-off/switch-on), then check the electrical cabinet design and cable routing for EMC compliance and the DRIVE-CLiQ wiring for interrupted cables or poor contacts.
Which parameter belongs to fault F36820?
The G130/G150 remedy cross-references p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave). r0949 and r2124 hold the coded message value.
