What it means
F01112 reports that the power unit connected to the Control Unit (CU) is not permissible for this combination — the CU cannot be used together with this power unit. The manuals describe the fault for SINAMICS G120, G120XA, G130, G150, S120 and S150; the concrete reason is stored as a decimal value in r0949, and the list of possible values differs slightly between the families (see below).
Why it appears
- The power unit connected to this Control Unit is not a permissible combination — the CU does not support it for this use.
- Which case applies is stored in r0949: an unsupported power unit type (e.g. PM240 on G130/G150/S120/S150, e.g. PM340 on G120/G120XA), a DC/AC power unit connected to a CU310, or an S120M power unit used for vector control — the last two are listed for G130, G150, S120 and S150 only.
What to check
- Read the fault value in r0949 and interpret it as a decimal number to identify which combination was rejected.
- Replace the non-permissible power unit with a component that is permissible.
Reading the message value
- The drive writes the reason for F01112 into r0949; interpret the value as a decimal number.
- 1 — Power unit is not supported (e.g. PM240 on G130, G150, S120 and S150; e.g. PM340 on G120 and G120XA).
- 2 — DC/AC power unit connected to CU310 not permissible (listed for G130, G150, S120 and S150).
- 3 — Power unit (S120M) not permitted for vector control (listed for G130, G150, S120 and S150).
Parameters the manual names
- r0949 — fault value: read it as a decimal number for this fault; the value (1, 2 or 3) identifies why the connected power unit was rejected.
Acknowledging and restarting
The drive triggers no automatic shutdown for this fault. Once the non-permissible power unit has been replaced by a permissible component, acknowledge the fault immediately; the acknowledgment clears the message.
What differs between the drive families
Straight from the manuals' own fields — F01112 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |

| S120, S150 | NONE | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2579 |
| G120 | NONE | IMMEDIATELY | Error in the parameterization / configuration / commissioning procedure (18) | — | SINAMICS G120 · p. 831 |

Questions technicians ask
What does SINAMICS fault F01112 mean?
The Control Unit has detected that the connected power unit cannot be used together with it — the combination is not permissible. The fault is described for SINAMICS G120, G120XA, G130, G150, S120 and S150.
How do I find the reason for F01112?
Read the fault value in r0949 as a decimal number. Value 1 means the power unit type is not supported (e.g. PM240 on G130/G150/S120/S150, e.g. PM340 on G120/G120XA), value 2 that a DC/AC power unit is connected to a CU310, and value 3 that an S120M power unit is not permitted for vector control; values 2 and 3 are printed for G130, G150, S120 and S150 only.
How do I clear F01112?
Replace the non-permissible power unit with a permissible component and then acknowledge the fault immediately. The drive performs no automatic shutdown for this fault.
