My MESA 7i95T wiring

 it means , that 1 click to MPG = 4 pulses for feed?

so what is the solution ? set 1/4 of the feed value ?

only use the input designated for MPG (foto - input A0,B0) ?

 



i am trying to understand the links

MPG wheel connection - fixed

MPG ENCODER INPUTS

Standard 7I95T firmware provides 4 quadrature MPG encoder inputs on isolated inputs 0 through 7.
Since the input threshold on isolated inputs is about 3V, its best to use sinking inputs (with the input common terminal tied to +5V) with TTL output level MPGs.

INPUT ENCODER 
0     QUADA-0      MPG 0
1     QUADB-0 
 
2     QUADA-1      MPG 1
3     QUADB-1 
 
4     QUADA-2      MPG 2
5     QUADB-2

6     QUADA-3      MPG 3
7     QUADB-3

 


The problem for me is that the MPG hand wheel function for inputs IN 00-07 cannot be selected from the submenu in the PNCONFG menu.
I don't know how to manually edit HAL.

MPG - initial attempts



is used original connection of MPG wheel to Encoder 4, configuration only with PNCconfig and manual editing of one component in HAL file based on the solution in this post :
162.243.45.186/39-pncconf/51627-mpg-issue-on-mesa-7i77

net joint-select-a     (b,c)


to

net axis-select-x    (y,z)

I need to change the scale and maximum speed settings.

It's a shame that the MPG configuration error in PNCCONFG hasn't been fixed - it would be possible for beginners (like me) to configure MESA 7i95T (and others...) using only PNCCONFG without manual editing
