Note:
This fault does not result in a safety stop response.
Fault value (r0949, decimal interpretation):
Parameter number of parameter that initiated the change.
See also: p9502 (SI Motion axis type (processor 1))
Remedy: The following should be carried out after the changeover:
- exit the safety commissioning mode (p0010).
- save all parameters (p0977 = 1 or "copy RAM to ROM").
- carry out a POWER ON.
Once the Control Unit has been switched on, safety message F01680 or F30680 indicates that the checksums in
r9398[0] and r9728[0] have changed in the drive. The following must, therefore, be carried out:
- activate safety commissioning mode again.
- complete safety commissioning of the drive.
- exit the safety commissioning mode (p0010).
- save all parameters (p0977 = 1 or "copy RAM to ROM").
- carry out a POWER ON.
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
Drive object: All objects
Reaction: NONE (OFF1, OFF2, OFF3)
Acknowledge: POWER ON
Cause: There is not sufficient memory space in the NVRAM on the drive to save parameters r9781 and r9782 (safety log-
book).
Note:
This fault does not result in a safety stop response.
Fault value (r0949, decimal interpretation):
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: -
Drive object: SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
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 total of Ti and To is too high for the set DP cycle. The DP cycle should be at least 1
current controller cycle greater than the sum of Ti and To.
Non-isochronous PROFIBUS: the DP cycle must be at least 4 x current controller cycle.
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 value
sensing clock cycle must be at least four times 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)
