A2M-80SV02430 servo and S2-SVD15 driver

Hi @sirbrialliance
Have you managed to get the S2-AVD driver working with Thanos, and have you fixed the EMI issue?
I'm looking for a more affordable servo/driver combo — the AASD units are way too expensive for my budget.
Thanks!

I have an HTLNC drive from AliExpress, which is similar to what you're describing. I recently purchased a BigScreen Beyond 2 (BSB2) VR headset. As soon as I turned on the AC servo, the BSB2 lost synchronization, which motivated me to investigate electromagnetic interference (EMI).

I bought a Faraday bag on Amazon and tested it. I found that placing just the motor's UVW cable inside the bag allowed the headset to work properly. After researching, I learned that AC servo cables (like the UVW) are notorious for generating noise, especially since mine was unshielded. I decided to focus on shielding that cable.

I purchased a woven copper braid (1/2-inch diameter) from Amazon: https://a.co/d/0Iw7Rsx. It was straightforward to install—you can stretch the braid to create a wide opening and slide it over the cable. I grounded it using a couple of ground screws on the DIN rail.

Unfortunately, even with the shielding, the BSB2 still won't sync reliably, so I'm returning it.

Please forget that copper braid. It's good as ground strap for the door of a cabinet, for example, but not for shielding cables. Replace the unshielded cable. It's not too expensive, around €1/m if you buy 25m.

You also have to install an EMI filter with a common mode choke at the AC input of the drives to block interference going into the power grid. Blaming the VR headset for the interference caused by the servo drives is no solution.

Thanks for the info. I really need this right now. I have one working but it has to sit almost outside the room so it doesn't interfere with the arduinos. I've got ferrite cores and I'm going to get an emi filter. I hope there's a place that ships cable that cheap to the US.

From what I've seen these motors should work just fine once the emi is dealt with.

The whine is not a problem. I can't really hear it. I have tinnitus though so maybe I'm just mentally blocking it. It would be impossible to hear over the engine of the car.

Other than that, no major differences from the AASD's.

I’m trying to keep this conversation constructive. I wasn’t suggesting the external braid as a permanent or ideal solution—only mentioning it because it had helped with several other interference issues in my setup. The VR headset was the one case where it didn’t completely solve the problem.

I’m also still working through the practical side of making motor cables, including how to handle the connectors. I’m looking for clarity on the best way to approach that part of the job. An example of the cable is a good start.

EDIT: That link is 3 conductors my servo has four conductors. PE is a ground conductor which is built into the connector on the motor.
