Hi there, all!
After restoring machine data from the archive, the machine can not switch on - there is no any alarms on CNC display, but drives, hydraulic and other systems not switching on after pushing the corresponig button. If we force to on the machine with the switch located in electrical cabinet, drives will start up for a few seconds, then the alarm "FM Accident prevention regulations UVV (SAVE_ASUP) => Power switch ON/OFF" appears and drives switch off. What is the correct way to fix it?
CNC is Sinumerik 840D powerline
