some good advice (pid)

peter.

I've done this, the truth friend does not quite understand the concept.

please guide me a little more

thanks

ultimate plot improved.

Thats quite a bit better and may actually be acceptable since this is a rapids move with rather aggressive acceleration and cutting moves will have lower velocities and accelerations

Peter,

I cut a little acceleration. tapeworm in the lead 800 to 600.

Watch these results.

one as defined proper acceleration.

how much would my maximum error right now.

peter,

What is the next step?

Or already set the PID?

And not I've noticed. LOL

thanks for all your cooperation

Can you increase P any? it looks like its more stable now

After getting P set I would start adding some 'I' term gradually

Peter,

achieve P = 5. more oscillate the servomotors.

D try, but accomplish nothing positive. more oscillate the servomotors.

I tested "I". There was no improvement. one thing I noticed is that the value of "Z" was diminishing. with increasing "I"

peter. I'm far from achieving my servomotors tuning?

I would not expect D to help much in s velocity mode servo (D is handled by the drive itself)

'I' may have to be fairly high before you see an effect
one way to adjust I is to add more until you get oscillation and then use about 1/2 to 1/3 the amount of I where oscillation started
