HI at all
I have a doubt, where is ladder when all data in CNC is cleared?
I know this ladder are stored in eprom, ok
For example, 0 series all data is cleared, after that, I inputing parameter 900´s
and when I upload all parameter why I can see ladder
I sorry all people but english is not my mother language

Depending on who the machine builder is etc, to be able to view the ladder logic is simply a parameter setting. (0 to 1 or 1 to 0) The option is a turn on/off. Possibly in the keep relays. I would suggest you contact the manufacture for the details required.
Good Luck!

Which language do you speak?
The ladder could be saved in a ROM memory or RAM memory, depends the configuration of the machine.
The parameter 9** tells to the machine from where is going to take the ladder, from a ROM (you can not erase the ladder from this) or from a RAM (you can erase the ladder from this memory, and if you don´t have the ladder in a ROM memory and you erased the ladder or the batteries death, the ladder was lost FOREVER)
I hope this information helps you.
