Hello,
I am trying to get a Bridgeport Interact 720 H TNC 2500 running, It was working before being moved, but mostly sitting for the last 3 years.
Machine information, and I have attached some pictures.
The spindle driver has been replaced with a Fagor Power Supply and Spindle Driver (PS25B4/AXD25) which require +400 VAC, that is tied to the main power inputs.
The transformers are configured X1 460 vac and X2 480 vac.
The spindle motor is a "GE Fanuc model 10 a06b-0501-b202 #7000 ac servo motor", is this the stock 720 motor?
I did not have access to 480 VAC, so I wired a 480 vac to 208 vac transformer backwards making it a step up transformer, with 220 vac going in I measured 495 vac out unloaded on a 15 kv transformer. I am sure the voltage will drop some when loaded.
I next powered up the machine and was happy to only see the driver board with only the green led lit and the control panel screen comes to life.
The Fagor PS/SD still has a fault led lit on the PS. Not sure why?
Also, the machine still has a block of wood between the spindle and table.
Current problems...
When I turn on the air compressor it sounds like a air leak some where and the air pressure never gets over 60-70 lbs.I also hear a kind of gurgling sound like air passing through a liquid, I think it is coming from the black box in the lower left of air/lubrication panel. I don't see any movement when this is going on. Any ideas?
The air not working should not stop the controller right?
When the power is applied the control panel becomes active and does the following:
Memory Test
Power Interrupted
I press CE button and then it gives one of three errors
Some thing about the Y axes out of position
The ATC is too close
And the last couple times, it showed FLASHING "Y-Measuring system defective B"
What I saw last on the screen.
