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:
- C306A0, critical error. After PLC sends the power off/EP signal to cobot, this error occurs without reason.
- 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
To correct, it happens after PLC sends the power on signal.
