    Hi Sean,

    You might try lower P gain or lower Acceleration to reduce overshoot.

    Adding D gain with a 2nd order Low pass filter of maybe 200Hz Q=1.4

    Tom

    Thank you so much for the help , i think i have it where it is workable , now to set it up in Kmotion.exe

    i have set up M3,M4,M5 and S in the tool setup , using your example in the CSS folder and the Motor starts and changes direction . but it doesn't Stop or display speed.

    i have the FACTOR set at 50 holes*4 edges = 200/60 or should i be using a different format as i read somewhere 1=3750 or 20157 = 3750

    i think i have read so many posts and guides now that i am confusing myself.

    If i use the zero button in step/response screen to stop the motor it goes to -2047 = -9.995v in the analogue screen and then when i start the motor again it ramps to zero then the speed i want , which is causing some of the the slow motor start

    regards

    Sean
