What it means
A35080 is raised by the safety monitoring channel of the TM54F when the checksum it calculates over the safety-relevant parameters — the value entered in r10004 — does not match the reference checksum that p10005 saved at the last machine acceptance. Depending on how the drive is configured, the same condition can also be signaled as a fault; the handling described below applies in either case.
Why it appears
- The calculated checksum over the safety-relevant parameters, entered in r10004, does not match the reference checksum that was saved in p10005 at the last machine acceptance — for example because safety-relevant parameters have been changed since that acceptance or a hardware replacement has not yet been acknowledged.
What to check
- Check the safety-relevant parameters and, if required, correct them.
- Set the reference checksum in p10005 to the actual checksum (r10004).
- Acknowledge the hardware replacement.
- Carry out a POWER ON (switch off/on).
- Carry out an acceptance test.
Reading the message value
- The drive enters the fault value in r0949; interpret it in binary (where the message value is printed as the placeholder %1, it carries this fault value).
- Bit 0 = 1: checksum error for functional SI parameters.
- Bit 1 = 1: checksum error for SI parameters for component assignment.
Parameters the manual names
- r10004 (SI TM54F parameter actual checksum, short name SI par CRC act): holds the checksum the drive currently calculates over the safety-relevant parameters; compare it against p10005.
- p10005 (SI TM54F parameter reference checksum, short name SI par CRC target): the reference checksum saved at the last machine acceptance; set it to the actual checksum to clear the mismatch.
- r0949 (fault value): read it in binary to see whether bit 0 or bit 1 is set.
Acknowledging and restarting
Once the safety-relevant parameters are correct, set the reference checksum in p10005 to the actual checksum and acknowledge the hardware replacement. Then switch the drive off and on (POWER ON) and carry out an acceptance test. When the condition is signaled as a fault, this POWER ON (switch off/on) is also the acknowledgment that clears it.
The same on every family
Every manual that describes A35080 gives it the same reaction, acknowledgement and message class.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| S120, S150 | NONE | NONE | Safety monitoring channel has identified an error (10) | Terminal Module (TM) | SINAMICS S120, S150 List Manual · p. 3209 |
| G130, G150 | NONE | NONE | Safety monitoring channel has identified an error (10) | Terminal Module (TM) | SINAMICS G130, G150 List Manual · p. 1877 |

Questions technicians ask
What does SINAMICS alarm A35080 mean?
The safety monitoring channel of the TM54F has found that the calculated checksum over the safety-relevant parameters (r10004) does not match the reference checksum saved in p10005 at the last machine acceptance.
How do I clear A35080?
Check and, if required, correct the safety-relevant parameters, set p10005 to the actual checksum, acknowledge the hardware replacement, then carry out a POWER ON (switch off/on) and an acceptance test.
Can A35080 also appear as a fault instead of an alarm?
Yes. Depending on the drive configuration, the same condition can be signaled as a fault, and it is then acknowledged by a POWER ON (switch off/on).
What do the bits of the A35080 fault value mean?
Read r0949 in binary: bit 0 = 1 signals a checksum error for the functional SI parameters, and bit 1 = 1 signals a checksum error for the SI parameters for component assignment.
