What it means
F01655 (manuals' title: SI P1 (CU): Align monitoring functions
) is raised when the drive cannot align the Safety Integrated (SI) monitoring functions of its two monitoring channels: no common set of supported SI monitoring functions was able to be determined. Which channels are involved depends on the drive — on the G120 the alignment runs between processor 1 and processor 2, while on the S120, S150, G130 and G150 it spans the Control Unit and the Motor Module/Hydraulic Module. The fault results in a STOP A that cannot be acknowledged.
Why it appears
- On the S120, S150, G130 and G150, where the two SI monitoring channels are distributed across the Control Unit and the Motor Module/Hydraulic Module: there is either a DRIVE-CLiQ communication error or communication has failed.
- On these drives additionally: the Safety Integrated software releases on the Control Unit and the Motor Module/Hydraulic Module are not compatible with one another.
- On the G120, where the alignment runs between processor 1 and processor 2: there is a communication error between processor 1 and processor 2 or communication has failed.
What to check
- Carry out a POWER ON (switch-off/switch-on) for all components; on the G120 the manual names no components, only the switch-off/switch-on.
- Upgrade the Motor Module/Hydraulic Module software (S120, S150, G130, G150).
- Upgrade the Control Unit software.
- Check the electrical cabinet design and cable routing for EMC compliance.
Reading the message value
- The fault value is stored in r0949 and is to be interpreted hexadecimal. The manuals print no decoding, because the value is only for internal Siemens troubleshooting.

Acknowledging and restarting
This fault results in a STOP A that cannot be acknowledged, so it is not cleared from the running state. The manual's remedy is to carry out a POWER ON (switch-off/switch-on) for all components. If the fault reappears, the remaining remedy steps apply: upgrade the Motor Module/Hydraulic Module software and the Control Unit software (where the drive has these components) and check the electrical cabinet design and cable routing for EMC compliance.
What differs between the drive families
Straight from the manuals' own fields — F01655 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2640 |
| G130, G150 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS G130, G150 List Manual · p. 1440 |
| G120 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | — | SINAMICS G120 · p. 843 |

Questions technicians ask
What does SINAMICS fault F01655 mean?
It means the drive could not align the Safety Integrated monitoring functions of its two monitoring channels — no common set of supported SI monitoring functions was determined. On the G120 the channels are processor 1 and processor 2; on the S120, S150, G130 and G150 they span the Control Unit and the Motor Module/Hydraulic Module.
How do I clear or reset fault F01655?
The fault results in a STOP A that cannot be acknowledged, so the manual's remedy is to carry out a POWER ON (switch-off/switch-on) for all components. If the fault reappears, upgrade the software versions and check the cabinet design and cable routing for EMC compliance.
Why does fault F01655 occur?
The listed causes are a DRIVE-CLiQ communication error or failed communication (on the G120, between processor 1 and processor 2), and Safety Integrated software releases on the Control Unit and Motor Module/Hydraulic Module that are not compatible with one another.
What is the fault value of F01655?
The drive stores it in r0949, to be interpreted hexadecimal. The manuals publish no decoding because the value is only for internal Siemens troubleshooting.
