hi, when you have got the same error, can u note the error number or error explanation? I think you should check alimantation stage(3 phases, outputs of the transformator, Power unit) ---

Hi Cezanne, Finally, I know the problem that cause my error. It’s because I’m stopping the program since the robot connects to the conveyor tracking. I know it, because when I stop the program and turn off the machine, the next day I turn on again the machine, it don’t show the same error. :stuck\_out\_tongue\_winking\_eye: by the way, thanks for your reply. Best regards, Carmila
