text: <s>[INST] Kinetix 5100 Configuration Signature Hi All, I am having some issues with the configuration signature on a few Kinetix 5100 drives. If you cycle the power to the control panel all of the Kinetix 5100 drives go into, what looks like, a STO fault. After some investigation it turns out that this is due to differences in the drive configuration signature and the PLC online version, of which you can resolve the differences and everything works fine. If I cycle the power again the same things happens, it is like the drive refreshes the signature each time it powers up and therefore is different to the PLC, and so it faults the drive. Does anyone know a solution to this issue, has experienced the same issue, or can suggest some things to check to see if I can sort this out. Naturally my customer is not happy that they have to go through the same issue each time they switch on the control panel. Kind Regards, Ian [/INST] Hi Ian, I asked around and found out that the same issue was experienced with the v2.01.06 of AOP (Add-on Profile) for Kinetix 5100. What's yours? The newest version (v2.01.17) is available. Regards, Kubi \\n </s>
