Hello again!
I checked 7i39 manual 2 more times, did not find any warning that
would tell not to pull up to 5V, so I turned PC off and set all the
5i23 connectors to pull up to 5V.
What I am seeing now makes me think that there is something wrong:

Hello, folks!
I would appreciate some advice on servo tuning.
I have Keling Nema23 BLDC servo motors attached to Mesa 7i39.
And also zero experience with this :)
The way I am doing the tuning is:
1) start Emc, hit F1 and F2;
2) open Machine - Calibration;
3) change P value, for example, from 1

We intend to use 7i23+7i47x2.
Where can we find SVST12_12_7I47 firmware and pinout?
