What it means
The drive raises F35230 under the manual title TM: Hardware fault when the Terminal Module (TM) in use signals internal errors. Because the errors sit inside the module, its signals may no longer be trusted: Signals from this module may not be evaluated because they are very likely to be incorrect.
When the fault becomes active, the infeed is switched off with OFF1 — with no reaction or OFF2 available as the alternative configured response — while the other drive objects involved take no automatic fault reaction. The manuals describe this code in the same words for the Terminal Module on the G130, G150, S120 and S150 platforms.
Why it appears
- The Terminal Module (TM) in use has signaled internal errors.
- As a consequence of these internal errors, the signals from this module are very likely to be incorrect and may not be evaluated any more.
What to check
- Take the signals of the affected Terminal Module out of evaluation — the drive flagged them precisely because they are very likely to be incorrect.
- Replace the Terminal Module; the manuals give replacement as the remedy, to be carried out if required.
- Switch the drive off and on again to acknowledge the fault and confirm during the restarted operation that it does not reappear.
Acknowledging and restarting
F35230 is acknowledged only by switching the drive off and on again (POWER ON); it does not clear while the converter remains powered. Because the infeed was switched off with OFF1, the drive returns to a ready state only after this power cycle. If the fault is raised again once the drive is switched back on, the Terminal Module concerned must be replaced.
What differs between the drive families
Straight from the manuals' own fields — F35230 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: OFF1 (NONE, OFF2) Servo: NONE Vector: NONE Hla: NONE | POWER ON | Hardware/software error (1) | Terminal Module (TM) | SINAMICS S120, S150 List Manual · p. 3221 |
| G130, G150 | Vector: NONE Infeed: OFF1 (NONE, OFF2) | POWER ON | Hardware/software error (1) | Terminal Module (TM) | SINAMICS G130, G150 List Manual · p. 1886 |

Questions technicians ask
What does SINAMICS fault F35230 mean?
The Terminal Module (TM) in use has signaled internal errors. Its signals are very likely to be incorrect and must not be evaluated any further.
How is fault F35230 acknowledged?
Only by switching the drive's power off and on again (POWER ON). If the fault reappears after the power cycle, the Terminal Module has to be replaced.
Do I always have to replace the Terminal Module when F35230 appears?
Replacement is the only remedy the manuals give, but it is only carried out if required. Power-cycle the drive first and replace the module if the fault comes back.
Which converters report F35230?
The code is described for SINAMICS G130, G150, S120 and S150, and the manuals state the cause, remedy and acknowledgment identically for the Terminal Module in each case.
