Siemens SINAMICS G120 - A01654 (F) SI P1 (CU): Deviating PROFIsafe configuration; F01655 SI P1 (CU): Align monitoring functions; F01656 SI P1 (CU): Parameter processor 2 error

4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G120 Control Units CU240B-2/CU240E-2
798 List Manual (LH11), 01/2016, A5E33839529
The following applies for p9501.30 = 1 (F-DI via PROFIsafe is enabled):
- PROFIsafe telegram 900 must be configured.
For p9501.30 = 0 (F-DI not enabled via PROFIsafe), the following applies:
- PROFIsafe telegram 30 must be configured.
A01654 (F) SI P1 (CU): Deviating PROFIsafe configuration
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The configuration of a PROFIsafe telegram in the higher-level control (F-PLC) does not match the parameterization
in the drive.
Note:
This message does not result in a safety stop response.
Alarm value (r2124, interpret decimal):
1:
A PROFIsafe telegram is configured in the higher-level control, however PROFIsafe is not enabled in the drive
(p9601.3).
2:
PROFIsafe is parameterized in the drive; however, a PROFIsafe telegram has not been configured in the higher-level
control.
Remedy: The following generally applies:
- check and, if necessary, correct the PROFIsafe configuration in the higher-level control.
For alarm value = 1:
- remove the PROFIsafe configuring in the higher-level F control or enable PROFIsafe in the drive.
For alarm value = 2:
- configure the PROFIsafe telegram to match the parameterization in the higher-level F-control.
F01655 SI P1 (CU): Align monitoring functions
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: An error has occurred when aligning the Safety Integrated monitoring functions on processor 1 and processor 2. No
common set of supported SI monitoring functions was able to be determined.
- there is a communication error between processor 1 and processor 2 or communication has failed.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, interpret hexadecimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (switch-off/switch-on).
- check the electrical cabinet design and cable routing for EMC compliance
F01656 SI P1 (CU): Parameter processor 2 error
Message class: Hardware/software error (1)
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: When accessing the Safety Integrated parameters for the processor 2 in the non-volatile memory, an error has
occurred.
Note:
This fault results in a STOP A that can be acknowledged.
Fault value (r0949, interpret decimal):
129: Safety parameters for processor 2 corrupted.
131: Internal software error
132: Communication errors when uploading or downloading the safety parameters.
255: Internal software error on the Control Unit.
