What it means
F49150 means that the cooling unit signals a general fault to the drive. The drive receives this signal as cooling unit feedback over an input on a Terminal Module, and p0266 defines the signal source from which these feedback signals are read. The manuals for S120/S150 and for G130/G150 describe the code with the same cause and the same remedy, so the steps below apply to both.
Why it appears
- The cooling unit signals a general fault to the drive.
What to check
- Check the wiring between the cooling unit and the input terminal on the Terminal Module.
- Check the external control device of the cooling unit.
- Compare the signal source set in p0266 for the cooling unit feedback signals with the input the cooling unit is actually wired to.
Parameters the manual names
- p0266 — selects the signal source (BI) from which the drive reads the cooling unit feedback signals; for this code, verify it points to the input on the Terminal Module where the cooling unit is connected.
Acknowledging and restarting
The drive coasts down when this fault trips. Once the cause has been removed, acknowledge the fault; the drive only restarts after the acknowledgement.
What differs between the drive families
Straight from the manuals' own fields — F49150 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | — | Auxiliary unit faulted (20) | None | SINAMICS S120, S150 List Manual · p. 3287 |
| G130, G150 | OFF2 | IMMEDIATELY | Auxiliary unit faulted (20) | None | SINAMICS G130, G150 List Manual · p. 1931 |

Questions technicians ask
What does fault F49150 mean on a SINAMICS drive?
It means the cooling unit signals a general fault. The feedback signal reaches the drive through an input on a Terminal Module whose source is set in p0266.
How do I fix fault F49150?
Check the wiring between the cooling unit and the input terminal on the Terminal Module, and check the external control device of the cooling unit. Acknowledge the fault afterwards so the drive can restart.
Which parameter belongs to fault F49150?
p0266, the signal source of the cooling unit feedback signals. Check that it matches the input the cooling unit is actually wired to.
