Do you think the whine sound could be reduced/removed if a SFX-100 user like @Mascot continued to run at 220v but substituted the Arduino with your AMC-AASD15A controller?

Does the high pitch whine have any relation to EMI or are the two completely unrelated? Was hoping if I could manage to reduce this whine it may help with my tracking issues I am having with my Index.

See my opinion on the matter about EMI above. My best guess would be to place choke filters on the cables of the index and any other device that is connected to the PC (even the USB cable for the AMC controller).


Also another way to battle with the EMI is to using proper filter on the power lines from the source, that works both ways, blocks EMI from and to the power line:

The EMI issues are a serious thing for those of us who stay in VR. One guy was saying that his Valve Index is gray screening on him whenever his SFX-100 is running. As it is I have no such issues with my NLRv3.

One of the guys has already tried this and it still didn't fix the issues he was having.

The thinking is that it will block EMI propagate from the power line to the PC power that way...

No, This is not related to the controller. Its combination of voltage + ground balance issue.

Actually, here is a better one that is rated at 16A to cover all servos:

Just bought this, desperate to find a solution here for both the noise and EMI Index grey screening so willing to try anything.

 

[RCHeliguy]

Are you going to run it inline to a 15A outlet strip feeding all your electronics?
Are you currently using a 110->220V step up transformer to drive your actuators?

This filter should be connected on the power line, before the power converter (110v to 220v). This way the noise won't be amplified by the power converter...

does 110v/220 at 60hz vs 50hz make a difference? (60hz here!)

Not really, it might change a little bit the whining noise frequency pitch but it will still be same amplitude.

If you guys are having trouble with EMI then check your cables. I've bought motors at many different sizes from both mige and no name aliexpress distributors. Each time I've asked for grounded and shielded cables. Each time they say oh yes of course no problem. Each time the cables have been unshielded. I had trouble with a mige direct drive wheel with my vive until I made my own cable for the power that was shielded and that solved it forever.

By the way I first checked that was the problem by wrapping the cable in aluminum foil and wrapping up a ground wire in it from the driver so its grounded. Pretty easy to try before investing in proper shielded cables.

If I take the traction loss (fifth actuator) how will it actually look like and how does it work?

I just want to confirm this is wired correctly? Left is going to outlet, right is going to power converter. What should I do with the ground from the power converter?

Can you take photos of the filter connectors? I can't see if there is only one ground connection or not.

If there is only one ground connection, connect the ground from the power converter side (that is not connected right now) to the same ground connector as the ground coming from the line (single point ground).

Yes there is only one ground connector on the line side on the left.

Yes there is only one ground connector on the line side on the left.

Connect the ground wires from both sides together then on that connector...

You need to have the ground connected so it won't create ground loops through the chassis...
