What it means
F01105 (CU: Insufficient memory) is generated by the Control Unit (CU) when its memory is not sufficient for everything that has been configured on it — the manual names as examples too many drives, function modules, data sets, Technology Extensions or blocks. For G120 and G120XA the manual restricts this statement to too many data sets being configured on the Control Unit; for G115D and G120C only the short fault table is given. The drive is brought to a standstill with OFF1. Depending on the drive's configuration, the same condition can also be output as an alarm; in that variant the manual specifies no automatic reaction and no acknowledgement.
Why it appears
- Too many functions have been configured on this Control Unit — the manual lists drives, function modules, data sets, Technology Extensions and blocks as examples (wording for G130, G150, S120 and S150).
- For G120 and G120XA the manual narrows the cause down to too many data sets configured on this Control Unit.
What to check
- Reduce the configuration on this Control Unit — the manual's examples are fewer drives, function modules, data sets, Technology Extensions and blocks; for G120 and G120XA the remedy is given directly as: reduce the number of data sets.
- If the configured functions are all needed, use an additional Control Unit (remedy stated for G130, G150, S120 and S150).
Reading the message value
- The message value is the fault value in r0949, interpreted as a decimal number.
- The manual gives no decoding for this fault —
Only for internal Siemens troubleshooting
— so there is nothing further to read out of the value on site.
Parameters the manual names
- r0949 — fault value of the message: for F01105 it is interpreted as a decimal number and, according to the manual, is only for internal Siemens troubleshooting, so it does not help to narrow the cause down on site.
Acknowledging and restarting
The fault is acknowledged with POWER ON: once the configuration has been reduced, switch the power supply of the Control Unit off and on again — a reset from the operator panel or from the commissioning tool does not clear it. If the fault reappears after the power cycle, the configuration still does not fit into the Control Unit's memory.
What differs between the drive families
Straight from the manuals' own fields — F01105 is not described identically everywhere.

Questions technicians ask
What does F01105 mean on a SINAMICS drive?
It means the Control Unit does not have enough memory for what has been configured on it — for example too many drives, function modules, data sets, Technology Extensions or blocks. On G120 and G120XA the manual phrases this as too many data sets being configured.
How do I clear F01105?
Reduce the configuration on the Control Unit (fewer drives, function modules, data sets, Technology Extensions or blocks), or use an additional Control Unit where the manual states that remedy. Then switch the power supply off and on to acknowledge the fault.
Why can I not acknowledge F01105 from the panel?
The fault is assigned POWER ON acknowledgement, so only switching the power supply off and on again clears it. A reset from the operator panel or the commissioning tool is not sufficient.
Can F01105 also appear as an alarm?
Yes, the same condition can also be output as an alarm depending on the drive's configuration. In that variant the manual specifies no automatic reaction and no acknowledgement.
