What it means
The manuals title this fault SI P1 (CU): Safety-related functions not supported. The Control Unit raises it when the connected module does not support the safety-related functions: on the S120, S150, G130 and G150 this is the Motor Module or Hydraulic Module — for example because its version is not the correct one — and on the G120 it is the Power Module. Because the module lacks these functions, Safety Integrated cannot be commissioned on the drive. This fault does not result in a safety stop response.
Why it appears
- The Motor Module/Hydraulic Module does not support the safety-related functions; the manuals give as an example that the Motor Module/Hydraulic Module version is not the correct one (S120, S150, G130, G150).
- The Power Module does not support the safety-related functions (G120).
What to check
- Identify the module concerned: a Motor Module or Hydraulic Module on the S120, S150, G130 and G150, a Power Module on the G120.
- Use a module that supports the safety-related functions — that is, replace the Motor Module, Hydraulic Module or Power Module with one of a suitable version.
- For a Motor Module/Hydraulic Module, upgrading the module software is given as an alternative to replacing it; no software upgrade is listed for the Power Module.
Acknowledging and restarting
The drive coasts down when the fault trips. After a supporting module has been fitted or the module software upgraded, acknowledge the fault immediately with a POWER ON — the power supply must be switched off and on again — so that Safety Integrated can then be commissioned.
What differs between the drive families
Straight from the manuals' own fields — F01660 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) | Control Unit (CU) | SINAMICS S120, S150 List Manual · p. 2645 |
| G130, G150 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | Control Unit (CU) | SINAMICS G130, G150 List Manual · p. 1444 |
| G120 | OFF2 | IMMEDIATELY (POWER ON) | Error in the parameterization / configuration / commissioning procedure (18) | — | SINAMICS G120 · p. 845 |
The drives this code lives on
F01660 is described for G120, G130, G150, S120, S150. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does SINAMICS fault F01660 mean?
The Control Unit reports that the connected Motor Module, Hydraulic Module (S120, S150, G130, G150) or Power Module (G120) does not support the safety-related functions, so Safety Integrated cannot be commissioned.
Does fault F01660 produce a safety stop?
No. The manuals state explicitly that this fault does not result in a safety stop response.
How do I fix F01660?
Fit a module that supports the safety-related functions; for a Motor Module/Hydraulic Module, upgrading the module software is given as an alternative. Afterwards the fault must be acknowledged with a POWER ON.
Why does my G120 show F01660 when commissioning Safety Integrated?
Because its Power Module does not support the safety-related functions, which is exactly what this fault reports; the remedy given is to use a Power Module that supports them.
