Title: Servo Humming
Post by: SScnc on March 05, 2010, 01:03:41 PM
Hello, I'm finishing up my first Servo based CNC conversion on a Mazak 14x40 lathe. My question is my Z axis servo has a humming coming from it, that almost sounds like a heart monitor. It hums, then, its almost like its beeping, but very quietly. Is this normal for servos?

I dont have any experience with DC Servos, only AC Servos. If AC Servos are  not tuned correctly you can get all sorts of weird noises from hissing to grating and grinding  sounds so I would imagine it would be the same for DC Servos.
