What it means
The drive's safety monitoring channel verifies by a checksum that the safety-relevant SI Motion parameters have not changed since the last machine acceptance. The actual checksum calculated over these parameters is entered in r9398; the reference checksum saved at the last machine acceptance is stored in p9399. When the two no longer match, the drive raises F30680 and brings the drive to a STOP A that can be acknowledged. Which hardware calculates the checksum depends on the family: on the S120, S150, G130 and G150 it is the Motor Module/Hydraulic Module, on the G120 it is processor 2. The fault value in r0949 (interpret decimal) tells you which group of SI parameters failed.
Why it appears
- The actual checksum calculated over the safety-relevant parameters and entered in r9398 does not match the reference checksum saved in p9399 at the last machine acceptance.
- Safety-relevant parameters have been changed.
- A fault is present.
What to check
- Check the safety-relevant parameters and correct them if required.
- Set the reference checksum in p9399 to the actual checksum currently in r9398.
- Execute the function "Copy RAM to ROM".
- Perform a POWER ON if safety parameters requiring a POWER ON have been modified.
- Carry out an acceptance test.
Reading the message value
The drive enters the fault value in r0949; interpret it decimal:
- 0 — checksum error for SI parameters for motion monitoring.
- 1 — checksum error for SI parameters for component assignment.
Parameters the manual names
- r9398 — SI Motion actual checksum over the safety-relevant parameters; read it and compare it against p9399.
- p9399 — SI Motion reference checksum saved at the last machine acceptance; set it to the actual checksum once the parameters are correct.
- r0949 — fault value; read it decimal to see whether the checksum error concerns motion monitoring (0) or component assignment (1).
Acknowledging and restarting
This fault results in a STOP A that can be acknowledged, and it is acknowledged immediately by switching the drive off and on again (POWER ON). Before the drive will run cleanly again, work through the remedy: correct the safety-relevant parameters, set the reference checksum p9399 to the actual checksum, execute "Copy RAM to ROM", perform a POWER ON if safety parameters requiring one were modified, and carry out an acceptance test.
What differs between the drive families
Straight from the manuals' own fields — F30680 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | OFF2 | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | Power Module | SINAMICS S120, S150 List Manual · p. 2988 |
| G130, G150 | OFF2 | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | Power Module | SINAMICS G130, G150 List Manual · p. 1687 |
| G120 | OFF2 | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | — | SINAMICS G120 · p. 925 |
The drives this code lives on
F30680 is described for G120, G130, G150, S120, S150. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does fault F30680 mean on a SINAMICS drive?
The checksum calculated over the safety-relevant parameters (r9398) does not match the reference checksum saved in p9399 at the last machine acceptance. Either safety-relevant parameters have been changed or a fault is present.
How do I clear F30680?
Check and correct the safety-relevant parameters, set the reference checksum p9399 to the actual checksum in r9398, execute "Copy RAM to ROM", perform a POWER ON if parameters requiring one were modified, and carry out an acceptance test.
What do fault value 0 and 1 for F30680 mean?
Read r0949 decimal: 0 means the checksum error affects the SI parameters for motion monitoring, 1 means it affects the SI parameters for component assignment.
Why does F30680 keep coming back after acknowledgment?
The fault stands as long as the actual checksum in r9398 differs from the reference in p9399. If safety-relevant parameters were changed, the reference checksum must be updated and the acceptance test repeated.
