Axis amp replaced - now I get strange sound from axis motor
Hey there,
Just replaced x axis ampon my VMC15xt (the old one was amc, the new one is glentek), everything works, I get some kind of sound from the axis motor (to me it sounds like a water running through some pipe). The noise is present as soon as I power up the machine, no matter if I move the axis or not.
Haven't try any machining yet.
My guess is it has something to do with those little pots, and tunning the amp. Any advices? Anybody has some kind of procedure? Thanks a lot, guys, you helped me a lot up to this point.

Do a Google search for "fadal axis ballance program "
I found a pdf that has the factory service programs. You'll have to scroll through to find the one you need.

I'm glad that I could help.
I really like the fadals and I think the DC machines runs smoother than the later AC drives.
I switch between 3 different A axis drives and reballancing the amp is part of it.
Balancing the other axis are basically the same.
I have 3 fadals as well and the amps arent identical. Some are more clearly marked.
You'll need to adjust the sig. and bal pots to what the service program says.
I like using a volt meter between pins 2 & 3 on one machine and on the other machine I go to ground and it's either lead 2 or 3. I don't know because the wires aren't labeled as the other.
