Hallo
everyone, I carry on with my test in the kflop board, this time I incorporated
or I install a quadrature scale to measure, the scale is 0.005mm
resolution,so 200 counts/mm.
if
the Kflop reed at 4X the count numbers/mm,
(because there are 4
different states in a complete cycle of the A B signals. So it is 200x4 = 800
counts/mm.)
My
motor has 200step/rev
the
driver has 1/16 µstep
The total nº µstep is
200x16= 3200 µstep/rev
The ball screw has 4mm pich so 3200/4= 800µstep/mm
The conection of the ball screw and motor ar 1:1 I mean
direct.
so the gain is : µstep of
motor/counts of encoder 800/800 = 1
The PROBLEM is that this gain (1) is
incorrect, if I put that value the measure of the scale is totaly diferent of
the motor .
To have the right measure in the kmotion in
the blue numbers I have to put 4 in the gain value.
WHY???? The Kflop does not read 4X or
I making something wrong?
This is the before step to make close loop with the stepper motor and the digital
scale, but before that I want to know this clear.
