4 Faults and alarms
4.2 List of faults and alarms
Note:
For the commissioning software, the units are only consistently displayed after a project upload.
F01690 SI Motion: Data save problem for the NVRAM
Message value: %1
Message class: Hardware / software error (1)
Drive object: All objects
Reaction: Vector: NONE (OFF1, OFF2, OFF3)
Infeed: NONE (OFF1, OFF2)
Acknowledge: POWER ON
Cause: There is not sufficient memory space in the NVRAM on the drive to save parameters r9781 and r9782 (safety
logbook).
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 NVRAM.
For fault value = 1:
- de-select functions that are not required and that take up memory space in the NVRAM.
- contact the Hotline.
Note:
NVRAM: Non-Volatile Random Access Memory (non-volatile read and write memory)
A01691 (F) SI Motion: Ti and To unsuitable for DP cycle
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: VECTOR_G
Reaction: NONE
Acknowledge: NONE
Cause: The configured times for PROFIBUS communication are not permitted and the DP cycle is used as the actual value
acquisition cycle for the safe movement monitoring functions.
Isochronous PROFIBUS:
The sum of Ti and To is too high for the selected DP cycle. The DP cycle should be at least 1 current controller cycle
greater than the sum of Ti and To.
No isochronous PROFIBUS:
The DP clock cycle must be at least 4x the current controller clock cycle.
Notice:
If this alarm is not observed, then message C01711 or C30711 – with the value 1020 ... 1021 – can sporadically
occur.
Remedy: Configure Ti and To low so that they are suitable for the DP cycle or increase the DP cycle time.
Alternative when SI monitoring integrated in the drive is enabled (p9601/p9801 > 0):
Use the actual value acquisition cycle p9511/p9311 and, in turn, set independently from DP cycle. The actual values
sensing clock cycle must be at least 4x the current controller clock cycle. A clock cycle ratio of at least 8:1 is
recommended.

Reaction upon F: NONE (OFF1, OFF2, OFF3)
Acknowl. upon F: IMMEDIATELY (POWER ON)
