A01066 Buffer memory: 70% fill level reached or exceeded
Reaction: NONE
Acknowledge: NONE
Cause: The non-volatile buffer memory for parameter changes is filled to at least 70%.
This can also occur if the buffer memory is active (p0014 = 1) and parameters are continually changed via a fieldbus
system.
Remedy: If required, de-activate and clear the buffer memory (p0014 = 0).
If required, clear the buffer memory (p0014 = 2).
In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is
cleared:
- p0971 = 1
- power down/power up the Control Unit

A01067 Buffer memory: 100 % fill level reached
Reaction: NONE
Acknowledge: NONE
Cause: The non-volatile buffer memory for parameter changes is filled to 100%.
All additional parameter changes will no longer be taken into account in the non-volatile buffer memory. However,
parameter changes can still be made in the volatile memory (RAM).
This can also occur if the buffer memory is active (p0014 = 1) and parameters are continually changed via a fieldbus
system.
Remedy: If required, de-activate and clear the buffer memory (p0014 = 0).
If required, clear the buffer memory (p0014 = 2).
In the following cases, the entries in the buffer memory are transferred into the ROM and then the buffer memory is
cleared:
- p0971 = 1
- power down/power up the Control Unit
See also: p0014 (Buffer memory mode)
A01069 Parameter backup and device incompatible
Reaction: NONE
Acknowledge: NONE
Cause: The parameter backup on the memory card and the device type do not match (e.g. a memory card with the parameter
backup of a SINAMICS CU230 is inserted in SINAMICS CU240).
The module boots with the factory settings.
Remedy: - insert a memory card with compatible parameter backup and carry out a POWER ON.
- insert a memory card without parameter backup and carry out a POWER ON.
- remove the memory card and carry out POWER ON.
- save the parameters (p0971 = 1).
F01105 (A) CU: Insufficient memory
Reaction: OFF1
Acknowledge: POWER ON
Cause: Too many data sets are configured on this Control Unit.
Fault value (r0949, decimal interpretation):
Only for internal Siemens troubleshooting.
Remedy: - reduce the number of data sets.
