Noises - hmmm. Hard to say but could be missed steps. Have you looked at the steppers to determine what current they draw? Have you tuned the driver so it's delivering the needed current. What happens when you try to run a stepper unloaded (disconected frm the lead screw)? Those are big motors and pull a fair amount of current. Very few 3DPrinters use NEMA 23s.

We need to run at that speed or close to it but we still couldn't get even half of it (60mm/s)Quote

200 x 16 / 581steps= 5.5077mm pitch for the ballscrew. Pretty unusual....
Ballscrews are faster than trapezoidal screws and threaded rods, but I doubt they can run at 127mm/s
I have 4mm pitch ballscrews in my printer and I'm happy to run them at 30mm/s ( 40mm/s tops )

Im not an expert but there are some things here that are likely to cause issues. Hopefully the more knowledgeable will jump in if this is relevant.
127mm/sec is fast. Many here are printing down at 30mm/s so I would reduce that.
You set the min speed to 7000 ???? What units is that in? Clearly the min speed needs to be lower than the speed you want to print at. And the max should be higher.
Heres the thing I am questioning - If you ask it to move above the max speed what is the resultant speed? If you min speed is to high can the controller/driver/motor handle it. The motors are driven by a series of pulses, the frequency is limited to the max the controller can provide. If you try to send at a higher frequency the timing could get screwed or the motors just not respond fast enough.
