Hi,
I have a noise signal every time I operate the Smartpad, please if someone could help me, he checked the ground and everything is fine. Thanks

and what are we looking at? who is he?
I have a noise signal every time I operate the Smartpad
Where is this noise being measured? Using what instruments? What are the scales on those waveforms?
this is a Ultrasound machine, this noise appears only when the smartpad is on
posts without content are just noise too. if you want others to help you, you need to be much more specific or this thread too may be regarded as noise/spam.
where is this noise appearing? in ultrasound signal?
is there a reason robot and ultrasound equipment need to be in close proximity?
if yes, are the two connected somehow? how exactly?
is the "noise" appearing every time you touch something on smartPad (for example clear messages)?
or only when robot moves?
did you try using external monitor and unpluging smartPAd?
does the problem persists when using HMI? if not, check if smartPad cable is routed near ultrasound feedback. coupling effect is increased when cable is coiled and most people do that with excess length without giving it a second thought.
Good mornig,
This noise signal only appears when the robot moves, and to move the robot I need the smarPad, I have been told that I must isolate it or do equipotential bonding. Ground comes from the electrical panel.The problem is that when I make the measurements, that interference is also mixed and for that reason I want to know how to disappear or know exactly where it comes from. If someone has already had that problem, could you help me, telling me how you solved it. Thank you
so the noise you see is not caused by smartPAD, it is caused by drives. and this is expected as they are much larger load. smartPAD merely initiates the motion and that is any motion, not just jogging as you initially assumed.
you still have not mentioned anything about ultrasound equipment type, the way it is installed or interfaced to robot etc.
things to keep in mind are:
if you want to reduce interference, keep thigs as separate as possible. all things....
so put robot in one city and ultrasound in another is one way to deal with the problem.
but if they need to be close together, you need to know they can interfere and mitigate those things.
both robot and the ultrasound equipment have documentation that tells you how to do that.
drives you mean motor?

Wait... you said before this was an sonic noise. Now you say it's an electrical noise. Which one?
You still haven't said where this noise is being measured. On the power mains? In the air? Is it in the wiring, or broadcast EMI?
Robots always produce high-frequency noise, it's the nature of AC servo motors. And the frequency is going to cover a wide band, as it changes with the speed of the motor. And with 6 motors all running at constantly-varying speeds, the bandwidth would be pretty wide.
I use an ultrasound machine to inspect the state of the pieces, that signal only appears when the arm moves and does not disappear until it stops. as the robot works at 220 V, a 110V two-phase connection has been made, I don't know if that's a problem.
You still aren't answering our questions. How do you expect us to help you when you provide no details?
how far away is it recommended to place the controller from the arm
the measurement probe goes into the water, there the noise increases naturally
You are still not answering any of our questions. Any more participation in this thread appears to be a waste of our time.
what do you mean? you want to separate robot controller and robot arm? they are fine at any distance cables will allow and moving them apart will make no difference.
if you want answers, why don't you answer questions already asked?
every time the robot moves, this signal appears marked in red, then disappears when the arm stops.
I interpret it as a noise, since it only appears when the robot works
Well anyway thank you very much, the only thing I wanted to find the cause of that signal that is generated when moving the robot. I don't want you to waste your time.
you have no idea what is going on and you are not even trying to...
you are observing problem in some sensor reading. do you know what "sensor" means? it is the 'sensitive' part of the system able to sense something. That is the part that needs the most delicate treatment. you did not even begin to explain where that part is.
in other words you need to stop looking at connection between smartPad and KRC, or between KRC and the robot arm. you REALLY should try to focus at part that is picking up the external "noise".
that is the part need to be shielded, isolated, moved away from anything that may interfere with it. this is of course described in your sensor manual (which you did not share). so how is anyone supposed to guess what you have there? do you really think there is only precisely one type of ultrasound system in the world? you provided nothing to go on and did not answer any questions. perhaps consider looking up GIGO principle.
