Remove PID gains, try a step response on analog input signal controlling speed and measure output? Then you have a good idea of response gains could be calculated on computer.
Have some other algorithm in course litterature, do not remember and have too look it up, do not have time now. > nicklas > > just to clear up a few things > > the rs482 is for a chinese windows based tuning program. it is completely > separate from linuxcnc. > > the drives do accept modbus but that is a job I have no fancy tackling with > linuxcnc lol > > and yes any tuning stuff you can find would be appreciated. the problem is > I cannot use Halscope yet. until I have the servos tuned already I think > pretty close.
