What it means
Alarm A35225 carries the title "TM: Zero mark synchronization held - encoder not in the ready state". It reports that the zero mark synchronization with the encoder to be emulated was held, and the reason it names is that this encoder is not in the "ready" state. As long as the encoder does not reach this state, the synchronization stays on hold.
Why it appears
- The zero mark synchronization with the encoder to be emulated has been held.
- The encoder is not in the "ready" state — the manual names this as the reason for the hold.
What to check
- Bring the encoder into the "ready" state. This is the only remedy the manual gives for A35225; no further checks are described for this alarm.
Acknowledging and restarting
Nothing has to be acknowledged here: the manual specifies no acknowledgement for this alarm, and the drive takes no reaction to it either. The condition is dealt with by bringing the encoder into the "ready" state, which removes the cause named above.
The same on every family
Every manual that describes A35225 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Application/technological function faulted (17) | None | SINAMICS S120, S150 List Manual · p. 3219 |

Questions technicians ask
What does SINAMICS alarm A35225 mean?
It reports that the zero mark synchronization with the encoder to be emulated was held, because that encoder is not in the "ready" state.
How do I clear alarm A35225?
Bring the encoder into the "ready" state — that is the remedy the manual gives. Acknowledging the alarm is not required.
Does A35225 stop the drive?
No. The drive takes no reaction to this alarm; the zero mark synchronization simply stays held until the encoder is in the "ready" state.
Which SINAMICS drives can issue A35225?
The alarm is described for SINAMICS S120 and S150.
