What it means
F32837 means that the drive has detected a fault on the DRIVE-CLiQ component concerned — the component connected as Encoder 2 — and faulty hardware cannot be excluded. Which component is affected and why is coded in the message value (see below). The drive is brought to a standstill along the ramp (OFF1) and must be acknowledged before it will start again. Depending on the drive's configuration, the same condition can also be issued as an alarm (A) or with no reaction (N).
Why it appears
- Fault detected on the DRIVE-CLiQ component concerned — for this message, the component connected as Encoder 2.
- Faulty hardware cannot be excluded.
- The fault causes reported in the message value are an error in the telegram header, or a receive or send error in which the telegram buffer memory contains an error (see the decoding below).
What to check
- Check the DRIVE-CLiQ wiring (interrupted cable, contacts, …).
- Check the electrical cabinet design and the cable routing for EMC compliance.
- If required, use another DRIVE-CLiQ socket (p9904).
- Replace the component involved.
Reading the message value
- The drive stores two pieces of information: the component number (%1) and the fault cause (%2).
- Decoding of the message value (r0949/r2124): 0000yyxx hex, where yy = component number and xx = error cause.
- 32 (= 20 hex): Error in the telegram header.
- 35 (= 23 hex): Receive error: the telegram buffer memory contains an error.
- 66 (= 42 hex): Send error: the telegram buffer memory contains an error.
- 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 F32837 here.
- r2124 (alarm value): carries the same coded information when the condition is issued as an alarm.
- p9904 (topology comparison acknowledge differences): belongs to the remedy step in which the DRIVE-CLiQ cable is plugged into another socket.
Acknowledging and restarting
Once the cause has been remedied, acknowledge the fault immediately and restart the drive; the drive does not start again until the acknowledgment has been made. No further reset sequence is described for this fault.
What differs between the drive families
Straight from the manuals' own fields — F32837 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Servo: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Vector: OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) Hla: OFF1 (NONE, OFF2, OFF3) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 2 | SINAMICS S120, S150 List Manual · p. 3120 |
| G130, G150 | OFF1 (IASC/DCBRK, NONE, OFF2, OFF3) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 2 | SINAMICS G130, G150 List Manual · p. 1797 |

Questions technicians ask
What does fault F32837 mean on a SINAMICS drive?
It reports a fault detected on the DRIVE-CLiQ component connected as Encoder 2, and faulty hardware cannot be excluded. The component number and fault cause are coded in the message value r0949, or in r2124 when the condition is issued as an alarm.
How do I clear fault F32837?
Check the DRIVE-CLiQ wiring for an interrupted cable or poor contacts, check the cabinet design and cable routing for EMC compliance, and if required use another DRIVE-CLiQ socket (p9904). If the fault persists, replace the component involved, then acknowledge immediately.
What do the fault causes 32, 35, 66 and 67 of F32837 mean?
32 (= 20 hex) is an error in the telegram header, 35 (= 23 hex) is a receive error, and 66 (= 42 hex) and 67 (= 43 hex) are send errors — in the buffer cases the telegram buffer memory contains an error. The value is read from r0949/r2124 as 0000yyxx hex, where yy is the component number and xx the error cause.
Can F32837 appear as an alarm instead of a fault?
Yes. Depending on the drive's configuration, the same condition can also be issued as an alarm (A) or with no reaction (N).
