Hello I got all of the control wiring figured out on the Fanuc A06B-6055-H106 window drive, but as soon as I apply voyage to the 0-10 volt input it gives an alarm 02 without ever making a sound or trying to start the motor. I also noticed that when just rolling the motor by hand the load meter would go all the way to the top and if you stop it in the right place will stay there.

I read something that sounds like that can be caused by a bad motor feed back sensor.

I guess any thoughts, and I guess my real question is there any reason I can’t just drive the Fanuc 7.5HP AC spindle drive motor with a cheap VFD?

It does have a separate spindle encoder as Muzzer mentioned earlier.

Thanks Gary
