Need help to set PID

[3D-CNC-Reutlingen]

i have flashed the tarocco succesfully , but i have trouble to set PID settings.
the board is connected with a programm named hterm. i used the info from your user manual to connect it and i can read the incoming data.
i tried to set mostly the p settings (tried i and d too) but i cannot see any difference.
The controller is connected to a 24V Motor with 7600rpm.
the encoder is labeled as: encoder response frequency 100kHZ ; base pulse count 11
the range i want to use the setup is from 10-8192Hz wich is given from a sps (fx14nt).
i tried using the programm suggested at crowdsupply but i couldnt figure out to send data from there nor i was able to see anything while i was connected and motor was running.
with hterm i tried to set values but couldnt see any difference, maybe slightly im not sure.
I also changed setting in firmware itself, build it and flashed it, but same problem.
It would help me a lot if someone could give me some clues what i am doing wrong, or where the problem is.
