Random error C306A0 and C283A3 without reason

[xiaojie.yang]

Hello,

There are 5 UR cobots running on our machine, and controlled through Ethernet/IP.
The software version is 5.11.8.

We have the following issues frequently and randomly:

1. C306A0, critical error. After PLC sends the power off/EP signal to cobot, this error occurs without reason.
2. C283A3, power not removed from the motors while in Emergency Stop. It randomly happens to random cobot.

Does someone have an idea of them?

I don’t know if they’re related, but I’ve been having some weird things happen like that on 5.11.5 and now 5.11.8

C268A Special Command: Received unhandled command cmd:20

Still working on it here. The weird part is the robot doesn’t actually show anything. The customer usually has to restart the robot and so the log starts over. I have noticed that this shows up in the Polyscope log around the time that the robot stops. (The issue was reported this morning around 14:48). [image]

To correct, it happens after PLC sends the power on signal.
