Hi everybody, first I wish all to be safe and healthy. As the title states, on a CMS marble cnc, the control is done through a GE Fanuc Series 180i-M running
1. windows 98 2. the software loaded is " cnc screen display function" . The whole machine was working well for many years. We replace the inverter on 2019 and for a year or more everything was ok. Now operating system loads normally the fanuc software starts but after some time, even without loading any parameters, hangs or freeze . When we close the software ( pressing alt+ F4 ) we gain manual control to the spindle . Any idea will be helpful . We have the ability to reinstall the software or the operating system, but before that is something we could check eg. some indication led on the motherboard? No error or alarm is noticed
