Greetings every one,
I have a plasma CNC machine (china make) has a simple 3 Faldic servos and hypertherm microedge controller. The machine is power via a large 3 phase generator. The works fine unless I increase the jog speed to 6000mmpm, it gives an alarm "HV" which says high input voltage but I checked it and it seems to be fine. The machine works at very slow speeds 2000-3000mmpm but upon increasing the jogging speed the servo drive fails. Any suggestions ?
