F01650 — SI P1 (CU): Acceptance test required

The manuals title this fault SI P1 (CU): Acceptance test required: the drive-integrated Safety Integrated (SI) function on monitoring channel 1 — in the G120 manual worded as processor 1 — demands an acceptance test. The drive executes a STOP A that can be acknowledged. The Message value %1 carries the fault value, which the drive also writes into r0949 as a decimal number; that value decides which condition applies and what has to be done.

• The manual's cause: the drive-integrated Safety Integrated function on monitoring channel 1 (G120: processor 1) requires an acceptance test.
• What triggered the demand is told by the fault value in r0949 — a changed safety parameter, a downloaded project, a checksum change found by the Safety logbook, mismatching checksums or enables between the two monitoring channels, missing or unsavable monitoring channel 2 safety parameters, or the follow-on of another boot-time safety fault (values 130 to 9999, decoded below).

1. Read the fault value in r0949 (interpret decimal) — each value has its own remedy.
2. 130: carry out the safety commissioning routine.
3. 1000: check the Safety Integrated Basic Functions (r9780) and adapt the reference checksum (p9799) — this step is not listed for the G120; carry out the safety commissioning routine again; replace the memory card or the Control Unit; using STARTER, activate the safety parameters for the drive involved (change settings, copy parameters, activate settings).
4. 2000 / 2001: check the safety parameters on monitoring channel 1 and adapt p9799; on monitoring channel 2 adapt p9899.
5. 2002: make the enable of the safety-related functions identical on both monitoring channels (p9601 = p9801).
6. 2003 / 2004 / 2005: carry out an acceptance test and generate an acceptance report — the procedure and an example report are provided in the SINAMICS S120 Function Manual Safety Integrated.
7. 2010: check the enable of the safety-related brake control on both monitoring channels (p9602 = p9802).
8. 2020: carry out the safety commissioning routine again; replace the memory card or the Control Unit.
9. 3003 / 3005 (S120/S150 and G130/G150 manuals): carry out the function checks for the modified hardware and generate an acceptance report.
10. 9999: carry out diagnostics for the other safety-related fault that is present.
11. G120C: the manual gives one instruction for this code — switch the Control Unit off and switch it on again.

• 130 — the safety parameters for monitoring channel 2 (G120: processor 2) are not available; this value is always output when Safety Integrated is commissioned for the first time.
• 1000 — reference and actual checksum on monitoring channel 1 are not identical (booting): the clock cycle time for the Safety Integrated Basic Functions (r9780) was adapted as a result of the changed current controller sampling time (p0115[0]); at least one checksum-checked piece of data is defective; or the safety parameters were set offline and loaded into the Control Unit (the G120 manual lists only the last two).
• 2000 — reference and actual checksum on monitoring channel 1 are not identical (commissioning mode): the reference checksum was entered incorrectly (p9799 not equal to r9798), or p9501/p9503 were not deleted when deactivating the safety functions (G120: p9501).
• 2001 — the same mismatch on monitoring channel 2 (p9899 not equal to r9898), again with p9501/p9503 possibly not deleted (G120: p9501).
• 2002 — the enable of the safety-related functions differs between the two monitoring channels (p9601 not equal to p9801); on the G120, between processor 1 and processor 2.
• 2003 — a safety parameter has been changed.
• 2004 — a project with enabled safety functions has been downloaded.
• 2005 — the Safety logbook has identified a changed functional safety checksum; acknowledged only with STO deselected.
• 2010 — the enable of the safety-related brake control differs between the two monitoring channels (p9602 not equal to p9802); not listed for drive object HLA.
• 2020 — an error occurred when saving the safety parameters for monitoring channel 2 (G120: processor 2).
• 3003 — a hardware-related safety parameter has been changed.
• 3005 — the Safety logbook has identified a changed hardware-related safety checksum; acknowledged only with STO deselected (3003 and 3005 in the S120/S150 and G130/G150 manuals).
• 9999 — follow-on response of another safety-related fault that occurred when booting and requires an acceptance test.

• r0949 — fault value: read it here as a decimal number; it selects the condition and the matching remedy.
• p0115[0] — current controller sampling time: changing it adapts the Safety Integrated clock cycle time (value 1000).
• r9780 — SI monitoring clock cycle (Control Unit): check the Safety Integrated Basic Functions here for value 1000.
• p9799 / r9798 — SI reference/actual checksum of the SI parameters (Control Unit): 2000 and 1000 mean p9799 does not match r9798 — check the monitoring channel 1 safety parameters and adapt p9799.
• p9899 / r9898 — the same pair for the Motor Module (monitoring channel 2): adapt p9899 for value 2001.
• p9501 / p9503 — SI enable parameters (Control Unit): delete them when deactivating the safety functions; leftovers cause 2000 or 2001.
• p9601 / p9801 — SI enable functions integrated in the drive (Control Unit / Motor Module): make them equal for value 2002.
• p9602 / p9802 — SI enable Safe Brake Control (Control Unit / Motor Module): make them equal for value 2010.

The fault results in a STOP A that can be acknowledged. After the cause for the reported fault value has been remedied — with 2003, 2004, 2005, 3003 and 3005 after the acceptance test with its acceptance report — acknowledge the fault; the acknowledgment requires a POWER ON, i.e. the power supply is switched off and on again. Values 2005 and 3005 can only be acknowledged when the STO function is deselected. For the G120C the whole response to this code is switching the Control Unit off and on again.
