Hello fellow metal enthusiast. I bought a nice machine but had problems getting running. First of all I have system alarm error 920 Servo alarm (1/2 axis)
I have sent out the servo drive and it checks out good. Then, I don’t know what to do next. I have removed the CPU board and I believe there is RAM board missing, or could be the whole PCB board? Does anyone had this problem?
Also the machine was not working for 4 years. The parameters probably are out. Anybody has backup?
Thanking in advance all your help.
