I'm a bit confused about the configuration page relating to axis resolution and velocity and how the C program motion, Step response, KCNC trajectory planner and jog speeds interplay. Are they consistent with each other?

Hi AZ,

Please read this wiki article and let us know if you still have questions.

I read the article but i have still a question about a servo installation. For example if i want the max motor revolutions to be 1500rpm, and the servo drive/motor gives 1024 counts/rev, what should i but in the velocity parameter.

1500 / 60 x 1024 = 25600 counts/sec

The servo drive gives an incremental output A,/A, B, /B. Does not Kflop read that x 4? So that kflop read every rev 1024 x 4 = 4096?

That's always confusing. It depends on whether the 1024 is quadrature cycles (sometimes referred to as "lines") or quadrature counts. You said counts so I assumed quadrature counts. If I'm wrong the result will be obvious so multiply by 4.
