Ringing coming from Sewing Machine

[RVacc]

Im running a Consew 287 RB 2.  There is a ringing coming from behind the door on the side of the head.  Its not constant and only starts when you start sewing fast.  When walking the machine there is no ringing.  Has anyone ran onto this issue before?  It is currently not affecting how the machine is running but it is something that i have yet to run into so i am a little stumped.

 

Thanks,

something hitting inside the machine?  a part against a part?

OK...Probably Not cause of this particular 'noise' problem.. But

I had a weird ( high pitch whine ) sound  coming from a machine when sewing a few years back. The more RPM's I put into the drive pedal, the louder the whining was. So I spend many minutes trying to isolate the part of sew machine the problem was coming from.
So Turned out. That it was a 'Radio' that was making the sound... LOL .. I always have the Tunes ♫ ♫  playing in the background on a old Sony sport radio up in corner of the shop when sewing. For some reason on that one particular day, the servo drive on that one machine that was plugged-in wall on same circuit as the Radio. The Servo transferred a 'whine' to FM Radio channel, and it was bleeding some frequency interference, and that what I heard every time I picked-up the RPM's on that one machine.
