Hi Gentlemen,

I am working on an LB15-W, when the operator powers up the machine the spindle drive comes up with a fault right away. I have no manual for this drive, it is a VAC Type A D-11. It has two rows of led's located about mid-drive (btw no cover included). On the top row the left one (of the two red led's) is on and a green led labled 2 is on. All other led's are off.

This appears to keep the clamps from working, due to the zero speed circuit not firing up.

The fault will not reset unless I wait about 5 to 10 minutes, power down the machine power back up and then press reset on the drive. Any clues to the fault or where I could get a manual for one of these at would be greatly appreciated.......I need enlightenment badly......have been chasing this ghost for about a month now...........
