Hi
Dear sir/Madam

I have a costumer whose machine is a vmc40 fadal milling machine.
I have to commission it
But it seems that the controller doesn't work at all like this:
Nothing appears on the monitor or sometimes there is a lot of cursors in rows and columns thet fills the monitor.
The keyboard doesn't work at all.
The emergency switch also doesn't work.
The red led of the interface board is alight but noot blinking.
The red leds of the axes cards are blinking.
We have +12v,-12v,+5v on the controller .

Would you please help me ?
Best Regards
Majid
