We have a 1993 VF0, about 4 months ago there was an X axis problem, trident machine sent down someone who didnt know what they were doing, and he ended up changing every circuit board on the machine. ($10,000 Bill)
Since then we started getting the 160 alarm every once and a while, but in the last month the machine will only run for about an hour in the morning, then alarm out. Turning it off and on does nothing.
The DC buss voltage will start at around 160 then progressively drop to 120-130.
We have 208-210 volts coming in to the machine.
I checked the servo board inputs they are all getting 160v.
I tried what someone said in a post here, to disconnect each servo board and check the buss volts.
If i disconnect any one of the servo boards it will stay at 160v.
I dont understand where the machine is reading the Buss voltage from?
Thank for any help, we really need this machine running again, and cant go to trident because we still owe them 5K.
