Hi Richard,

What is the max motor speed you have set for the on-line mode of the controller?
It seems you need to reduce it a little bit.

Also I think your P term is a bit aggressive. Can you set it to 30 or less?


Thanks

99 % and 100% for the 2 motor speed setting.
and PID 30.0.0


30 rpm and 480mm/s

Ok,

Set On-line speed to 85%
Set Offline speed to 85%

And set P = 25


Give it a try. I think it will be much smoother.

Don't forget after testing to set the offline speed to 25% or less so it will be slower for the homing function (park motors slowly)


Thanks

I needed all the speed to adjust well.
I do not have a PC connected, just the card to a USB hub

I have to test again, I do these tests tomorrow
I would like you do with the oscilloscope. but I can not seem to set the oscilloscope;
where you connect the probe?

[tronicgr]

Connect the probe on the pin row "S" of the analog input on the AMC1280USB, and the potentiometer on the Screw terminal.

The alligator clip on the probe is the GND.

that's what I did.
I must have a problem adjusting the oscilloscope ...

I do not see the downhill and overtaking.
I do not control well this scope ...
I wonder if I'm not a function that is the problem.

I have 1V per division.
the fastest rate.

I think I set the oscilloscope speed to 100ms/div on the video but you can set it to more.


There are lots of videos to learn how to use it:

oh ok I'll watch it ...
Youtube and tutorials, there's something for everyone!
thank you
