The unit of pos-scale is increments/distance unit, like steps/mm or steps/inch.
If you motor's encoder has 500 pulses/rev, then it is 2000 increments/rev.
With a axis movement of 5 mm/motor revolution you should set pos-scale = 2000/5 and 2000/180 respectively.
400 and 11.111

It may be possible to set the increments/rev separately from the encoders value, check the drive manual if the above doesn't match.

 

Not sure what you mean by encoder_value.
You have the cia402.x.pos-scale to work with.
Instead of mathematically figuring it out, multiply the current value with 6.5/2 = 3.25 and try again.
If you find that number matches a known relation, use that.

I think the following errors follows from the pos-scale. At least get this right first.

mine too, do you fix that

Did you start the motor?

Hello,
I'm trying to start the motor but it's not working, I tried via halrun and via sudo ethercat upload -p and motor enters OP, but it doesn't accept OP_STATUS, always 0, and the motor dont move, please can you help me somehow.

I have been trying to solve these problems on my own with very little headway:

When the Servo moves 2 inches, LinuxCNC registers it as ~6.5inches regardless of the encoder_scale value

joint following error when I try to jog over ~60in/min (linuxcnc units)

joint following error when try to home (probably related)

I haven't even gotten to the real configuration and am already failing :'/
Help is appreciated
