11.3 Safety messages for SINAMICS S120
F01690 SI Motion: Data backup problems for NVRAM
Explanation There is not enough memory space in the drive NVRAM to save parameters r9781 and r9782 (Safety log‐
book).
Note:
This fault does not result in a safety stop response.
Fault value (r0949, interpret decimal):
0: There is no physical NVRAM available in the drive.
1: There is no longer any free memory space in the NVRAM.
Remedy For fault value = 0:
Use a Control Unit with NVRAM.
For fault value = 1:
Deselect functions that are not required and use the memory space in the NVRAM.
Contact the Hotline.
A01698 (F) SI P1 (CU): Commissioning mode active
Response NONE
Acknowledg‐ NONE
ment

Remedy Not necessary
A01699 (F) SI P1 (CU): Switch-off signal path test required
Response NONE
Acknowledg‐ NONE
ment
Explanation The time set in p9659 for the forced checking procedure of the safety switch-off signal paths has been
exceeded. The safety switch-off signal paths must be re-tested.
After the next time that the "STO" function is deselected, the message is withdrawn and the monitoring time
is reset.
Note:
This message does not result in a safety stop response.
The test must be performed within the specified maximum time (p9659, maximum 9000 hours) in order to
comply with the specifications in the standard for detecting faults in time and the conditions to calculate the
failure rates of the safety functions (PFH value).
Operation for longer than this maximum time is permissible, if it can be ensured that the forced checking
procedure is performed before persons, who are dependent on the safety functions correctly functioning,
enter the hazardous area.

Remedy Select STO and then deselect again.
