What it means
A01514 is raised when a parameter could not be written to during a reconnect operation — for example while the drive is booting or a download is running, but it can also occur in normal operation. The object that could not be written is always a BICO input (signal sink). The drive responds by resetting the affected parameter to its factory setting. Depending on the drive's configuration, the same condition can also be issued as a fault.
Why it appears
- During a reconnect operation (e.g. while booting or downloading, but also possible in normal operation) a parameter was not able to be written to.
- The example the manual gives: when writing to a BICO input in double word format (DWORD), the memory areas can overlap in the second index — p8861 is cited as an example of such an input.
- The affected parameter is then reset to the factory setting.
What to check
- None — the manuals state the remedy is not necessary. The drive itself has reset the affected parameter to its factory setting.
- If you need to know which parameter was affected, read the alarm value in r2124 as a decimal number.
Reading the message value
- Message value:
Parameter: %1
— the drive enters the number of the affected parameter here. - Alarm value in r2124, to be interpreted as a decimal number:
Parameter number of the BICO input (signal sink)
that could not be written.
Parameters the manual names
- r2124 — alarm value: read it as a decimal number to obtain the parameter number of the BICO input (signal sink) that could not be written during the reconnect.
- p8861 — CI: IF2 PZD send double word: the manual's example of a BICO input in double word format (DWORD) whose second-index write can fail because the memory areas overlap.
Acknowledging and restarting
As an alarm, A01514 does not have to be acknowledged and needs no remedy — the manuals state that none is necessary. If the drive outputs the same condition as a fault, it must be acknowledged immediately.
What differs between the drive families
Straight from the manuals' own fields — A01514 is not described identically everywhere.

| S120, S150 | NONE | NONE | Error in the parameterization / configuration / commissioning procedure (18) | None | SINAMICS S120, S150 List Manual · p. 2617 |

Questions technicians ask
What does SINAMICS alarm A01514 mean?
During a reconnect operation — e.g. while booting or downloading, but also possible in normal operation — a parameter (a BICO input) could not be written to. The drive then resets the affected parameter to its factory setting.
Which parameter caused A01514?
Read the alarm value in r2124 as a decimal number — it holds the parameter number of the BICO input (signal sink) that could not be written. The message value of the alarm also carries the parameter number.
Does A01514 have to be acknowledged or repaired?
No. The manuals state the remedy is not necessary, and as an alarm it does not need to be acknowledged. Only if the drive issues the same condition as a fault must it be acknowledged immediately.
Why does A01514 appear after a download?
A reconnect runs while a download is being carried out, and during it a parameter write failed. The manual's example is a write to a double word (DWORD) BICO input where the memory areas overlap in the second index, e.g. p8861.
