Hi,
I have been struggling getting a Kuka KR 60-HA with a KRC4 controller working for some time now. Upon booting I get error messages "EtherCAT communication timeout. Packets missing" and "Could not set IP address. Unable to configure IP address automatically." on the SmartPad with "No connection to KRC possible" appearing after some time. The icons at the top are red, IP is yellow. On the front of the cabinet where the 6 LEDs are, the bottom right one is red.
When I plug up a monitor I get "Unable to establish connection to the KRC. Robot control not possible."
Thinking it was a software error, I have reinstalled KSS to no avail, and even had the retailers send out a freshly installed hard drive that they had tested on their end, but upon installing it there was no change. Kuka support thinks it's a damaged CCU board, but the retailers are less sure. Before I spend the 10 grand on getting a technician out here or the month on waiting for a new CCU board to arrive, is there anything else I should check or try? The machine was working before it was shipped to us.
I have a lot of images and a KRCdiag here.
Thank you for any help
