So it has something to do with some sort of lag in the servo driver. I'll
be emailing leadshine
Today I received a second AC806 drive in the mail. It is a V1 ACS806.
The V1 is simpler to tune. It only has a current loop Kp and Ki, as well as
position loop Kp, Ki, and Kd.
I tried that on the same motor that the AVS806V2 is having trouble with.
Following error is now down to under 20 counts

That seems like a very small motor, and a very fast travel.
Is it possible that the motor is simply running out of steam?

If you can't fix it, you don't own it.

Ok this makes sense. Thanks all for your explanations. I guess I just
wasn't sure what was reasonable behavior and what wasnt.
So if the motor is rated for 36v, and the drive is rated for 80 volts max.
How much voltage can I get away with delivering to the drives without
damaging equipment?

Thanks to everybody for the information. If anything it helped me
understand the nature of servos better as I've been sitting here tweaking
the machine.
I tried 2 experiments to see if I could get better results.
#1. Give it 80Volts: I hooked the driver up to an 80v PS. The drive clearly
had

#2. Run the motor with no load: I disconnected the motor drive belt.
Re-tuned the servo and then started running it in linux cnc. Net result...
exactly the same behavior.

I think you should tune the drive with the load that it
I recently installed an ACS806 brushless drive along with a BLM57130
leadshine motor. The motor is a 130W motor with a 4000ppr encoder.
The controller is a step and direction type, with the encoder feedback

I have tuned it up and it seems to be tuned well, and has a low following

The problem is that it seems to rapidly increase from there. 0.1mm around

This is just my opinion, but to me 130 Watts is way too small,
especially with a router where you might need
