Hi
I have a new power supply that I wanted to test. I wired up the servo that had the noise. Ran the
servo and no strange noise at all. Does this tend to mean it could be a tuning issue. The test did NOT
include the motor connected to the 320 Gecko. Also both the new and the old motor are making the
same noise when I run G code. I assume again its a tuning or EMI interference problem.

Are you taking about the same motor as the OP, bgolash ? Or is this a different problem.

[Novett]

Its the same problem. Its a servo motor DC brush type.
To test the old motor it was attached to a new power supply.
The encoders were not used. Nor was it attached to a 320 Gecko.
I assume I should have mentioned I was bench testing the old motor.

Hi Novett

I am still a bit confused. You keep leaving out half the essential details: without them no-one can help you.

> I have a new power supply that I wanted to test. I wired up the servo that had the noise.
Normally the word 'servo' would refer to a servo drive such as the Gecko 320X. Are you instead referring to a DC motor when you talk about a 'servo'?

If what you are saying is that running the motor straight off a DC PS does not make the same noise, then it is reasonable to assume that the Gecko 320X may be causing the noise in the motor. Yes, a DC brush motor can make quite a noise if driven by a supply with lots of oscillation on it. That then may be a servo (drive) tuning problem.

But not always. You haven't told us what sort of PS you are using. My spindle motor was very noisy when driven by an SCR-based servo drive; switch to a MOSFET-based servo drive and it was quiet. But I don't think that will be happening here.

I'm sorry, but I could make very little sense out of what you have written.
I was under the impression that it was a motor which was making the noise, not the servo.
Are you saying that the test you ran with your new PS included just the PS and the Gecko, but no motor? Or what?
I'm confused.

Me too... Is Novett ,bgolash they guy who posted the video ? Huh ?
