EMI?

has anyone had any problems with emi? (TM2-AM3-HT65)

im not having a problem yet but im building a cart for my components and am curious about any interference issues.

im looking at faraday rolls to wrap the component dividers with but im not 100% sure how necessary it is or if ill be fine with the ht65 being 1.5 feet from the controller and computer.

Whatcha think?
 
Curious too. I have a bunch of ferrite cores I scrounged a while back from an old projection TV. I would be interested in which cables (and where along the cable) they should be. Thanks.
 
Generally this has not been a problem with the ethernet connection. USB on the other hand would sometimes require ferrite chokes, commonly found on keyboard and mouse cables.
 
is there anything in the controller or maybe the pc that are particularly sensitive to however much emi the plasma may put out? my controller and plasma will be separated by the sheet metal of the "desk" but ill be putting the pc tower in a box with the plasma about a 1.5 foot gap between the two.
 
Being that the AM boxes are connected via Ethernet EMI hasnt been much of an issue. I would just make sure you are not coiling up your cables that you are twisting them in the middle to create a "infinity" symbol to make sure you are not creating fields on the cables themselves.
 
What about the other cables, like height control, motor cables, etc.? Does it matter where the choke goes on the cable? Is it better to have near the controller for example or in middle of cable? (?) Thanks.
 
If you do plan on putting chokes on the wires I would put them closer to the controller. As far as the other cables there is plenty of shielding to help dissipate the EMI. IT would mainly be "communication" cables that require it.
 
Accumove 3 is an industrial robust product that's CE certified being compliant with EN61800-3:2004 +A:2012; EN55011 (Radiated and Conducted Emissions), EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-5, EN61000-4-6.
If a choke were to be fitted it is best placed near to the controller however it shouldn't be required.
AM3 uses TCP/IP protocol is used to communicate between VMD making it very robust supporting auto resend and data correction. The protocol ensures the data arrives correctly. If a prolonged event occurs causing a disconnect then the control will simply pause if it's running a part program.
