my machine is configurition by 1 ppmac,2acc24e3(8channel include 4pwm,4vppfeedback and
4analog,4vppfeedback);FEEDBACK FIGURE IS GOOD
now I use one channel include 1pwm and 1vpp,current loop tune figure
IS VERY GOOD
openloop tune figure IS VERY POOR
again I use one channel include 1analog and 1vpp,use same motor and feedback,openloop tune figureIS VERY POOR
I don't know why it is?
