What it means
F33896 is raised by the CU when the properties of the DRIVE-CLiQ component connected as Sensor Module for encoder 3 — the component named by the fault value — have changed in an incompatible fashion with respect to the properties stored when the drive booted. The manuals describe the condition identically for the S120/S150 and the G130/G150, and in both cases it concerns Sensor Module Encoder 3. Depending on how the drive is configured, the same condition can also be issued as an alarm (A) or with no reaction (N).
Why it appears
- The DRIVE-CLiQ component serving as Sensor Module for encoder 3 — the one named by the fault value — now reports properties that are incompatible with the properties recorded when the drive booted.
- A trigger named by the manuals is that a DRIVE-CLiQ cable or a DRIVE-CLiQ component has been replaced.
What to check
- Carry out a POWER ON.
- If a component was replaced, use the same component type and, if possible, the same firmware version.
- If a cable was replaced, use only cables whose length is the same as or as close as possible to the length of the original cables, and ensure compliance with the maximum cable length.
Reading the message value
- The drive writes the component number into the message value and into r0949; the fault value is to be interpreted as a decimal number and identifies the DRIVE-CLiQ component (Sensor Module for encoder 3) whose properties changed.
Parameters the manual names
- r0949 — fault value of this message; read it as a decimal component number to see which DRIVE-CLiQ component at encoder 3 raised F33896.
Acknowledging and restarting
The fault is acknowledged immediately. Because the drive compares the connected hardware against what was stored at boot, the remedy is to carry out a POWER ON so the drive boots again with the DRIVE-CLiQ component and cables now connected; any replacement must follow the rules above.
What differs between the drive families
Straight from the manuals' own fields — F33896 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Servo: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2) Vector: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2) Hla: OFF2 (NONE, OFF1, OFF3, STOP2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 3 | SINAMICS S120, S150 List Manual · p. 3176 |
| G130, G150 | OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2) | IMMEDIATELY | Internal (DRIVE-CLiQ) communication error (12) | Sensor Module Encoder 3 | SINAMICS G130, G150 List Manual · p. 1846 |

Questions technicians ask
What does SINAMICS fault F33896 mean?
The DRIVE-CLiQ component used as Sensor Module for encoder 3 has changed its properties in an incompatible way compared with the properties stored at boot. The component number of the affected component is stored in r0949, interpreted as a decimal value.
How do I clear fault F33896?
Acknowledge the fault immediately and carry out a POWER ON. If you replaced hardware, fit the same component type and, if possible, the same firmware version, and for cables use the same or nearly the same length within the maximum cable length.
Why does F33896 appear after replacing a DRIVE-CLiQ cable or component?
The drive compares the properties of the connected component with those from the last boot, and the manuals name such a replacement as a possible cause. Matching the component type, firmware version and cable length to the original avoids the mismatch.
How can I see which component triggered F33896?
Read r0949, the fault value of the message, and interpret it as a decimal component number. It names the DRIVE-CLiQ component at encoder 3 whose properties changed.
