What it means
F35003 is raised when a fault on the Terminal Module 54F (TM54) has been acknowledged with the safe acknowledgment (p10006), but the drive also requires an additional acknowledgment at the Control Unit. In other words, acknowledging the TM54F fault on the module alone does not finish the job — the condition stays visible until the Control Unit has acknowledged it too. The manuals for the G130/G150 and the S120/S150 describe this code with the same cause and the same remedy.
Why it appears
- A fault on the Terminal Module 54F (TM54) was acknowledged using the safe acknowledgment (p10006).
- An additional acknowledgment is also required at the Control Unit and has not yet been given.
What to check
- Acknowledge all faults on the Control Unit (BI: p2102).
- Alternatively, acknowledge all faults on the drive object TM54F (BI: p2103, p2104 or p2105).
- Note that a fault acknowledgment is triggered with a 0/1 signal.
Parameters the manual names
- p10006 — SI Motion acknowledgment internal event F-DI (processor 1): the safe acknowledgment with which the fault on the TM54F was already acknowledged; this code reports that it alone is not sufficient.
- p2102 — BI: Acknowledge all faults: trigger here to acknowledge all faults on the Control Unit.
- p2103 — BI: 1st acknowledge faults: one of the acknowledge inputs for acknowledging all faults on the drive object TM54F.
- p2104 — BI: 2nd acknowledge faults: one of the acknowledge inputs for acknowledging all faults on the drive object TM54F.
- p2105 — BI: 3rd acknowledge faults: one of the acknowledge inputs for acknowledging all faults on the drive object TM54F.
Acknowledging and restarting
The fault is removed by performing the missing acknowledgment: a 0/1 signal at the selected acknowledge input, either on the Control Unit (BI: p2102) or on the drive object TM54F (BI: p2103, p2104 or p2105). The manuals describe no further reset step for this code beyond that acknowledgment.
The same on every family
Every manual that describes F35003 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 3198 |
| G130, G150 | NONE | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1868 |

Questions technicians ask
What does SINAMICS fault F35003 mean?
It means a fault on the Terminal Module 54F was acknowledged using the safe acknowledgment (p10006), and an additional acknowledgment at the Control Unit is also required.
How do I clear F35003?
Acknowledge all faults on the Control Unit (BI: p2102), or acknowledge all faults on the drive object TM54F (BI: p2103, p2104 or p2105). A fault acknowledgment is triggered with a 0/1 signal.
Why does F35003 appear even though I already acknowledged the TM54F fault?
Because the safe acknowledgment (p10006) on the Terminal Module 54F alone is not enough — the drive also requires the acknowledgment at the Control Unit.
Is F35003 handled differently on G130/G150 than on S120/S150?
No — both manuals describe the same cause and the same remedy for this code.
