Hi Amir, not really sure what you are meaning.
The servos encoder have 2000 line (8000 counts per rev) and the gearing on the axis is 2.5:1 with 5mm pitch screws so resolution will be 0.00025mm and I am hoping to get the tuning so I have a following error of 20 counts/20mS so that would mean the axis would trip if it was ever 0.005mm out of position.
Is that what you mean?
