Hi, customer has R-30iB cabinet with M-900iA/600 robot.
Today the 2.0A fuse in Process I/O board CA (A16B-2201-0470/10F) blew when robot was going to change tool and PRIO-093 alarm was shown in screen. When we replaced the fuse and switched power on the fuse was blown again right away. We thought that the reason was in EE cable since the fuse didn`t blow at first when we disconnected that, however at some point the fuse was blown also when EE was disconnected. The customer told us that same fuse has blown before sometimes and when they have changed that then it has been working fine again.
One thing that comes to my mind is that there might be loose wiring somewhere that we couldn`t recognize but is there anything else that would cause this kind of behavior?
We have A16B-2201-0470/07C I/O board in stock. Can we try to change that?
