SINAMICS G120 / Control Units CU240B/E-2 Parameter Manual (LH11), 01/2011
F30651 SI P2: Synchronization with Control Unit unsuccessful
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The drive-integrated "Safety Integrated" function requires synchronization of the safety time slices on processor 1
and processor 2. This synchronization was unsuccessful.
Note:
This fault results in a STOP A that cannot be acknowledged.
Fault value (r0949, decimal interpretation):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (power off/on).
F30655 SI P2: Align monitoring functions
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 (power off/on).
- check the electrical cabinet design and cable routing for EMC compliance
F30656 SI P2: Parameter processor 2 parameter error
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, decimal interpretation):
129: Safety parameters for processor 2 corrupted.
131: Internal software error on processor 1.
255: Internal software error on processor 2.
Remedy: - re-commission the safety functions.
- replace the memory card or Control Unit.
F30659 SI P2: Write request for parameter rejected
Reaction: OFF2
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The write request for one or several Safety Integrated parameters on processor 2 was rejected.
Note:
This fault does not result in a safety stop response.
Fault value (r0949, decimal interpretation):
10: An attempt was made to enable the STO function although this cannot be supported.
15: An attempt was made to enable the motion monitoring functions integrated in the drive although these cannot be
supported.
16: An attempt was made to enable the PROFIsafe communications although this cannot be supported.
18: An attempt was made to enable the PROFIsafe function for Basic Functions although this cannot be supported.
20: An attempt was made to simultaneously enable both the drive-integrated motion monitoring functions via
integrated F-DI and STO via terminals, even though these cannot be supported at the same time.

Remedy: Re fault value = 10, 15, 16, 18:
- check whether there are faults in the safety function alignment (F01655, F30655) and if required, carry out
diagnostics for the faults involved.
- use a Control Unit that supports the required function.
Note:
STO: Safe Torque Off
