Hello! We are currently utilizing a Kinetix 5500 for managing an eccentric conveyor motor. We have been encountering sporadic and intermittent occurrences of a "Control Synch Fault" error on the drive. According to the manual, this error occurs when four packets of feedback data are missed between the drive and Logix controller, resulting in the drive faulting and necessitating a hard reset. Despite checking the cabling and upgrading the firmware, the issue persists. Our Ethernet cable is connected through a switch, which the manual specifies should be IEEE1588 compliant, pertaining to the Synchronous Ethernet Standard. We have been informed that the ports have been properly configured for this standard. While this fault may seem specific and esoteric, it is worth mentioning in case others have encountered or heard of it. Any insights or knowledge regarding the Kinetix 5500 and synchronous ethernet would be highly valued.
Hello dano65, there are numerous factors that could be causing this issue. In order to better assist you, I will need additional information about your setup. Is this the sole drive you are using? What is the update time set for your motion group? What kind of switch are you currently utilizing? If you have an ethernet-connected HMI, where is it positioned within your network in relation to your K5500 drive? Providing these details will help us troubleshoot and resolve the issue more effectively.
Thank you, Jobbe. I will collect the necessary information and follow up with you promptly.
I have encountered this issue multiple times with Kinetix 5500 servo drives. After thorough research, I have discovered that the most effective solution is to replace the servo drive unit.
Reviving this discussion as it remains important and already ranks high on Google search results. We are experiencing connectivity issues with Kinetix 5500 connected to a switch. Despite rearranging the connection order to direct PLC to servos before the switch, the problem persists. Since the switch lacks PTP support, an ETAP should be utilized. Efforts are underway to obtain an ETAP for troubleshooting. Any developments in resolving this issue will be updated here.
If you're experiencing a fault related to IGMP snooping, a technote provides valuable information on how to resolve it. While the article focuses on K5500 and Stratix 2500 switches, similar issues have been encountered with Stratix 5700 and Kintetix 5700 models. To prevent future issues, consider using switches that support PTP. Disabling IGMP snooping has proven to be an effective solution.

From what you've described, it looks like you've covered most of the basic troubleshooting steps that the manual recommends. However, since you mention that your Ethernet cable is connected through a switch, have you checked the integrity of that switch? Even if it's supposedly configured for the IEEE1588 standard, a glitch or malfunction there could be disrupting the connection. Also, just to rule this out, have you tested another Kinetix 5500 with the same setup to see if the problem is with the specific drive you're using or the system as a whole? Occasionally, such errors could be due to a problem with the actual hardware.
Hello! It seems you've tried the most common troubleshooting options already. However, in addition to checking the ethernet cables and ensuring the switch is IEEE1588 compliant, have you considered investigating the device that is sending these feedback packets to your Logix controller? It could be that there's a latency issue on that end causing the packets to be missed. Also, sometimes the issue can be with the compatibility between the Kinetix 5500 drive and the Logix controller. This kind of intermittent issue could potentially be a symptom of that. Just sharing some thoughts based on my experience. Best of luck in resolving this issue!
Hey there! It sounds like you've already done a lot of the troubleshooting groundwork. One thing to consider might be the switch itself—while it may be IEEE1588 compliant, some switches handle timing and data packet transmission differently, which can still lead to synchronization issues. Have you tried monitoring the network for latency or packet loss? Sometimes even minor disruptions can lead to those missed packets. Also, if possible, testing with a direct connection to eliminate the switch as a variable could provide more clarity on the fault. Good luck!
