I am encountering issues with 2 Kinetix 5500 drives that consistently display Node FLT 01 errors at random intervals. Despite PTP being disabled on the switch, it appears that interference from other connected devices may be causing this issue. Would it be advisable to test running the ethernet cables outside of the Panduit system to eliminate potential noise interference from neighboring cables?
Have you checked the motion clock jitter value on these drives to determine if excessive electromagnetic interference (EMF) is causing issues? Are you using Rockwell RJ45 patch cables or custom cables for connectivity?
Clock jitter has not presented itself as a problem so far, as we have not encountered any issues with time synchronization or clock jitter faults. Our solution has been to use custom patch cables sourced from our trusted electrical supplier.
LarryBeaut recently mentioned that clock jitter is not a problem for their setup, as they have not experienced any issues related to time synchronization or clock jitter. They have been using custom patch cables sourced from their electrical supplier. Although there is a technote suggesting that non-shielded non-Rockwell cables may not seat correctly and lead to faults, it is unlikely to be the issue but should still be explored. In a previous installation of 60 6500s, Larry experienced problems where the shield cases were just long enough to intermittently short out the RJ45 jack, causing a similar issue to what is being discussed.
I will investigate further, but I suspect there may be a different underlying issue causing them to fail simultaneously. If it were just an occasional short, I would expect only one of them to fail at a time. Appreciate the insight, thank you.
It's a definite possibility that the ethernet cables running alongside other cables in the Panduit system could be causing noise interference, leading to your Node FLT 01 errors. In my experience with Kinetix drives, issues like this can often be traced back to electromagnetic interference. I'd recommend running the cables outside the system as a test. If it resolves the issue, you might want to consider using shielded ethernet cables or rearrange your cable management scheme for separation from potential interference sources within the system.
I agree with your line of thinking. It could very well be that some sort of environmental noise is triggering Node FLT 01 errors on your Kinetix 5500 drives. Conducting a test run with the ethernet cables outside the Panduit system would eliminate the variable of potential interference from nearby cables. However, ensure your test setup is as close to your original environment as possible, except for the isolation of ethernet cables. This will ensure that any change in the error pattern can be attributed to the newly isolated variables. Do remember to share your findings, it would be interesting to see if this resolves your issue!

Answer: - The Node FLT 01 error typically indicates a fault related to the drive's communication with the network or other devices.
Answer: - You can try disabling PTP on the switch and checking for possible interference from other connected devices that may be causing the errors.
Answer: - Yes, it could be beneficial to test running the cables outside of the Panduit system to see if it helps eliminate potential noise interference from neighboring cables and devices.
