What it means
A01654 is the alarm the drive issues under the printed title “SI P1 (CU): Deviating PROFIsafe configuration”. It comes from the Safety Integrated function of the Control Unit and reports that the configuration of a PROFIsafe telegram in the higher-level control (F-PLC) does not match the PROFIsafe parameterization in the drive. This message does not result in a safety stop response.
Depending on the drive configuration, the same condition can also be issued as a fault (F) or without a reaction (N).
Why it appears
- The PROFIsafe telegram configured in the higher-level control (F-PLC) and the PROFIsafe parameterization in the drive do not match. The drive distinguishes two directions of this mismatch via the alarm value:
- Alarm value 1: a PROFIsafe telegram is configured in the higher-level control, however PROFIsafe is not enabled in the drive (p9601.3).
- Alarm value 2: PROFIsafe is parameterized in the drive, however a PROFIsafe telegram has not been configured in the higher-level control.
What to check
- Read the alarm value in r2124 and interpret it as a decimal number to see which of the two mismatches the drive has detected.
- Check the PROFIsafe configuration in the higher-level control and, if necessary, correct it — the manual gives this as the general remedy for both alarm values.
- For alarm value 1: either remove the PROFIsafe configuration in the higher-level F control, or enable PROFIsafe in the drive (p9601.3).
- For alarm value 2: configure the PROFIsafe telegram to match the parameterization in the higher-level F-control.
Reading the message value
- The drive writes the alarm value into r2124; interpret the value as a decimal number.
- 1 — a PROFIsafe telegram is configured in the higher-level control, however PROFIsafe is not enabled in the drive (p9601.3).
- 2 — PROFIsafe is parameterized in the drive, however a PROFIsafe telegram has not been configured in the higher-level control.
Parameters the manual names
- r2124 (alarm value): read here, interpreted as a decimal number, to determine whether the drive lacks the PROFIsafe enable although the F-PLC has a telegram (1), or the drive is parameterized for PROFIsafe while the F-PLC has no telegram (2).
- p9601 (SI enable functions integrated in the drive (Control Unit) / SI enable fct CU): PROFIsafe is enabled in the drive via p9601.3 — the switch to set when the higher-level control has a PROFIsafe telegram but the drive does not (alarm value 1).
Acknowledging and restarting
As an alarm, A01654 requires no acknowledgment in the drive — it disappears once the PROFIsafe configuration in the higher-level control (F-PLC) matches the parameterization in the drive. No safety stop response is involved, so no safety-related reintegration is needed either. If the drive configuration raises the same condition as a fault instead, it must be acknowledged immediately by switching POWER ON after the mismatch has been corrected.
What differs between the drive families
Straight from the manuals' own fields — A01654 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1440 |
| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2639 |
| G120 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | — | SINAMICS G120 · p. 843 |

Questions technicians ask
What does A01654 mean on a SINAMICS drive?
It is the alarm “SI P1 (CU): Deviating PROFIsafe configuration”: the PROFIsafe telegram configured in the higher-level control (F-PLC) does not match the PROFIsafe parameterization in the drive.
Does A01654 trigger a safety stop?
No. The message does not result in a safety stop response — it is a configuration mismatch between F-PLC and drive that must be corrected on one of the two sides.
How do I clear alarm A01654?
Read the alarm value in r2124: if it is 1, remove the PROFIsafe configuration in the higher-level F control or enable PROFIsafe in the drive (p9601.3); if it is 2, configure the PROFIsafe telegram to match the parameterization in the higher-level F-control.
Why does A01654 appear although the drive keeps running?
The condition is signalled as an alarm — it can also be issued as a fault (F) or without a reaction (N) — and causes no stop response; it warns that F-PLC and drive disagree about the PROFIsafe telegram until the configuration is aligned.
