I just acquired an 1995 VM-20 with the centurion V. The spindle drive comes right up and is showing no faults on its screen. The 3 axis drives have no leds lit as if they are off?
I have 308vdc at the big blue cap and all the fuses check ok.
There is 24vdc between #12 and #22.
I checked power supply and the voltages are correct going into the boards.
Any suggestions of what to check next?
It has the glentek sma 8215 drives in it.
