Hello,

I'm using kflop with servo drives which takes STEP/DIR position input. The Kflop is set for STEP/DIR output but this seems to invalidate any PID loop parameters.
Whatever is set in P,I,D - output allways seen 0 in step response screen and no effect.

From Step response it looks like there is constant delay from output to actual position. Attached is proof how 2x changed velocity produces constant 2x changed position error.
I was willing to tune it out - but P,I,D just does not work.

What is the correct way to go in such situation?
