OmniCore system failure

Hello everybody...

On an IRB 1300-11/0.9 robot I'm having system crashes even when it's not running, but when the motors are turned on. This is an OmniCore with RW 7.8.0. and Wizard version 1.3.2. Has anyone experienced this or have any suggestions as to what might be happening?
Thanks!

Hi DS186...

Thank you for your answer.

I mean System Failure. See the picture... (Falha de Sistema) in portuguese is Sistem Failure.

I saw that the system is very old, I'll update soon, but I have 3 robots in the same cell, same software, same eletrical connections, but only one is doing this. Happens when the robot is in Motor On state and program stoped.
