Então, para devolver o equipamento à operação temos que redefinir a NCU "NC e PLC", e restaurar o backup. Isso acontece toda vez que você desliga o equipamento e liga-o de volta depois de algumas horas. Alguém pode me ajudar, a razão da perda dos programas e parâmetros?

Posting in English will help you to get more response to your question. This is the translation of your question: Edinho31 Good evening I would like some help, after turning on the equipment and initializing it basically loses some user cycle files and axis parameters. So to return the equipment to operation we have to reset the NCU "NC and PLC", and restore the backup. This happens every time you turn off the equipment and turn it back on after a few hours. Can anyone help me, the reason for the loss of programs and parameters? NCU 573.5 Regards, Jen_Moderator

PISCEAN 2010 Posts: 8092 Rating: (884)	Hello, How old is NCU? Do you get any alarm or message related to BATTERY? I guess your NCU battery must be about to exhaust, i.e. its power is insufficient to back up SRAM for longer time that is how partial data loss is observed. If battery is OK i.e. recently replaced, it could be problem of NCU motherboard or loose connection of motherboard in NCU box etc. etc. I suggest you to have series start up & back up of NC/PLC data, which will be helpful to you in future in case of battery replacement (if not recently replaced) or in case of NCU problem. So please check above point.

From what I've been following the equipment, it didn't give any battery alarm, even so due to having to restore the system every time the machine is off, I changed the NCU battery to see if the fault goes away. I have a saved backup of the NC/PLC. Note: The NCU must be about 15 years old.
