motor tuning conversioni

[JeffB]

I looked at the formulas for converting the motor tuning but the resultant values seem very low:

 

..................…..Turbo.....Power

ServoKp......…...18990 ….9.495E-16

ServoKi…………. 16000 ….8E-20

ServoKvfb...........1800 ….1.7091E-19

ServoKvff………….2060 ….1.95597E-19

ServoKaff………..49000....4.65255E-18

ServoMaxInt..4194304....3.98249E-13

 

Does this make logical sense? Note that PosSf and Pos2Sf are 1 on both

 

PS I tried lining up the columns uses tabs and spaces, both to no avail. Hence the dots.

What formulas are you using for the conversion? According to the ones in the "I-Variable Equivalent" app note and the Software Reference Manual, we get results like:

 

Servo.Kp = 18990 * 96 / (2^19 * 1) = 3.477

Ahh, I was using 2e19. Got it; thanks;
