F01111 — CU: Mixed operation of drive units illegal

F01111 is raised by the Control Unit (CU) when power units of different drive types are operated on one and the same Control Unit — a mixed operation of drive units that the manuals call illegal. All manuals that describe this fault state the same causes and the same remedy, so the explanation below holds for every converter family on which the code appears.

• Drive units of different types are operated together on one Control Unit.
• Illegal combination named in the manuals: SINAMICS S together with SINAMICS G.
• Illegal combination named in the manuals: SINAMICS S together with SINAMICS S Value or Combi.

1. Read the fault value in r0949, interpreting it as a decimal number: it gives the number of the first drive object with a different power unit type, i.e. the point where the mixing begins.
2. Establish which power unit types are operated on this Control Unit and where one of the illegal combinations occurs (SINAMICS S together with SINAMICS G, or SINAMICS S together with SINAMICS S Value or Combi).
3. Change the configuration so that only power units of one particular drive type are operated with the Control Unit — this is the remedy the manuals give.
4. Acknowledge the fault immediately once the mixed operation has been removed.

• The drive outputs the fault value as message value %1; the same value can be read in r0949.
• Read the value as a decimal number, not as a bit pattern.
• Meaning: number of the first drive object with a different power unit type.

• r0949 (fault value): read here, interpreted as a decimal number, to identify the number of the first drive object whose power unit type differs from the others.

First remove the illegal mix — only power units of one particular drive type may be operated with one Control Unit — and then acknowledge the fault immediately; no further reset action is described for this code.
