Weeke optimat 145 ,NUM controller problems.

[jurgis1991]

Hi we have Weeke optimat 145 year 1998.It is the NUM 1020 controller that is having issues.The red def light illuminates as soon as the num starts up.This is what I see when I attach the display to the 37-pin connector:


I understand that the problem is a memory checksum error, meaning that some data has been corrupted in the memory.Despite having a backup of every file that has to be loaded into the controller, I am unable to establish a connection from my computer to the controller.

It has been 26 years, the controller might have reached the end of its life, better change a new controller.

Hey Jurgis,

This is an easy fix, it looks like the battery from your battery-backed RAM on this CNC needs to be changed.
I could connect you with someone to provide the battery and walk you through the process of establishing COM and restoring your data.
