I is useful for getting rid of steady-state error.
What happens if you go higher with P? Does it start oscillating? More D might help you get more P and still be stable.
On one axis of my machine I found that I needed negative D. This was a sign that the motor direction and encoder direction disagreed with each other, and swapping one helped a lot.

I noticed that before I adjusted the "I" value all of my moves were exactly 1 thousandth off in the positive direction. putting in some "I" helped with that problem.

DaOne, greetings.
I have a 3 DC servo motors Getty's model 20. (A06B-0602-B021). and I have the mesanet kit 5i25-7i77.
The query is if you could guide me how to make the connection between the servo drive ( A06B-6045-H005/H006) and 7i77 and the connection of the encoder and the 7i77.
Thank you in advance for your attention.
Jorge Viloria.
