What it means
F32812 reports that a cycle requested from the Control Unit — or the RX-/TX timing that goes with it — is not supported at the Sensor Module for Encoder 2. The drive stores a fault value in r0949 that tells you, interpreted as a decimal number, which of four cases applied. 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
- A cycle that was requested from the Control Unit, or the RX/TX timing of that cycle, is not supported; the fault value in r0949 distinguishes which of the four cases the drive detected.
What to check
- Read the fault value in r0949 and interpret it as a decimal number to identify which case occurred (see the list below).
- Carry out a POWER ON for all components, i.e. switch them off and then switch them on again.
Reading the message value
The message value %1 carries the fault value, which the drive also stores in r0949 — interpret it as a decimal number:
- 0: Application cycle is not supported.
- 1: DRIVE-CLiQ cycle is not supported.
- 2: Distance between RX and TX instants in time too low.
- 3: TX instant in time too early.
Parameters the manual names
- r0949 — fault value: for this code, read the value stored here as a decimal number; 0 or 1 means the requested application or DRIVE-CLiQ cycle is not supported, 2 means the distance between the RX and TX instants in time is too low, and 3 means the TX instant in time is too early.
Acknowledging and restarting
The drive coasts down on this fault and must be acknowledged before it will start again. Carry out the remedy first — a POWER ON, switching all components off and then on again — then acknowledge the fault immediately and restart the drive.
The same on every family
Every manual that describes F32812 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | Sensor Module Encoder 2 | SINAMICS S120, S150 List Manual · p. 3117 |
| G130, G150 | OFF2 | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | Sensor Module Encoder 2 | SINAMICS G130, G150 List Manual · p. 1795 |

Questions technicians ask
What does fault F32812 mean on a SINAMICS drive?
The encoder evaluated as Encoder 2 does not support a cycle requested from the Control Unit, or the RX/TX timing of that cycle. The fault value stored in r0949, read as a decimal number, shows which of four cases applies.
How do I clear fault F32812?
Carry out a POWER ON for all components — switch them off and back on again. Then acknowledge the fault and restart the drive.
Which fault values does F32812 report in r0949?
0 means the application cycle is not supported, 1 means the DRIVE-CLiQ cycle is not supported, 2 means the distance between the RX and TX instants in time is too low, and 3 means the TX instant in time is too early.
Can F32812 also 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).
