It seemed easier to me set it as a linear axis and measure.. how can i set it as a rotary "A" and tune it to 360 degrees ?

I have a rotary axis as x. normally i use steps per unit as 200 and velocity as 120. I have calculated a full rotation on x axis exact value of x12.6 and my 90 degree rotation is x3.15,
On another machine i was able to make a different reduction.
I made
Steps per: 195.4 and velocity: 36
Then i calculated an absolute rotation as X6.407,
after that when i try to send x axis to 6.407 i saw that is going somewhere else like x6.38,
I tried to change values like making steps per:1.954 and velocity:3600
In this calculation my full rotation was x640.7
i can get x640.7 on full rotation but my 90 degree rotation was x160.175 and i could'nt get exact value. it went x160.08 and measurements were wrong on table.
Any suggestions for this situation ?

if i set 8000 to "step per" it means that it will turn 3200 RPM right ? (for this calculation)

again a little confused !!! cant we turn this servo continuous 3200 Rotation Per Minute ?? or 533.333 Rotation Per Second ?

i didnt mean any movement of axis.. i just mean, how many  "step per" do we need to turn motor 3200 RPM with 2000 line encoder.. we need totally 426,666 KHZ but.. what could we set "step per" from motor tuning to turn servo 3200 RPM ??

i understood that i'll need 426Khz for 2000 line - 8000 in quadrature for 3200 RPM ! but what will be the "step per" in this calculation ?  ( 8000 ? )

if we have 2000 line encoder,, how many step per do we need to turn this same servo motor 3200 RPM

thank you, again and again !! now everything is clear..

does it works for closed loop operation ?  --->

http://www.rogersmachine.net/encoderinfo.html

it says that " Alerts the operator of positioning errors on each axis. "
