What it means
F01690 is reported by the Control Unit (CU) when there is not sufficient memory space in the NVRAM on the drive to save the parameters r9781 and r9782 — the safety logbook of SI Motion. NVRAM stands for Non-Volatile Random Access Memory (non-volatile read and write memory). The drive does not respond to this fault with an automatic stop, and the fault does not result in a safety stop response. Which of the two underlying situations applies is shown by the fault value in r0949.
Why it appears
- The NVRAM on the drive does not have sufficient memory space to save the parameters r9781 and r9782 (the safety logbook).
- There is no physical NVRAM available in the drive at all, so the safety logbook data cannot be stored (this corresponds to fault value 0).
What to check
- Read the fault value in r0949 and interpret it as a decimal number; it tells you which of the two situations the drive has detected.
- Fault value 0: use a Control Unit NVRAM.
- Fault value 1: deselect functions that are not required and that take up memory space in the NVRAM.
- Fault value 1: if the memory space cannot be freed this way, contact Technical Support.
Reading the message value
- The drive writes the fault value into r0949; interpret the value as a decimal number.
- 0 — there is no physical NVRAM available in the drive.
- 1 — there is no longer any free memory space in the NVRAM.
Parameters the manual names
- r0949 — read out here which case applies: fault value 0 (no physical NVRAM in the drive) or fault value 1 (no free memory space left); interpret the value as a decimal number.
- r9781 — SI checksum to check changes (Control Unit): one of the two safety logbook parameters the drive could not save in the NVRAM.
- r9782 — SI time stamps to check changes (Control Unit): the second safety logbook parameter the drive could not save in the NVRAM.
Acknowledging and restarting
The drive only removes this fault when its power supply has been switched off and on again (POWER ON acknowledgement); it cannot be cleared while the drive is running. The fault itself does not result in a safety stop response.
What differs between the drive families
Straight from the manuals' own fields — F01690 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | Infeed: NONE (OFF1, OFF2) Servo: NONE (OFF1, OFF2, OFF3) Vector: NONE (OFF1, OFF2, OFF3) Hla: NONE (OFF1, OFF2, OFF3) | POWER ON | Hardware/software error (1) | Control Unit (CU) | SINAMICS S120, S150 List Manual · p. 2669 |
| G130, G150 | Vector: NONE (OFF1, OFF2, OFF3) Infeed: NONE (OFF1, OFF2) | POWER ON | Hardware/software error (1) | Control Unit (CU) | SINAMICS G130, G150 List Manual · p. 1458 |
| G120 | NONE (OFF1, OFF2, OFF3) | POWER ON | Hardware/software error (1) | — | SINAMICS G120 · p. 849 |

Questions technicians ask
What does fault F01690 on a SINAMICS drive mean?
The Control Unit could not save the SI Motion safety logbook — parameters r9781 and r9782 — because there is not sufficient memory space in the NVRAM, or no physical NVRAM is available in the drive.
How do I fix F01690?
Read the fault value in r0949, interpreted as a decimal number. If it is 0, use a Control Unit NVRAM; if it is 1, deselect functions that are not required and that take up memory space in the NVRAM, and contact Technical Support if that does not free enough space.
Does F01690 trigger a safety stop?
No. The manual states that this fault does not result in a safety stop response.
Why can I not acknowledge F01690 in operation?
The fault requires a POWER ON acknowledgement, so the drive only clears it when the power supply has been switched off and on again.
