The HLFB signal comes from motor, in case if there is any problem with the motor so this HLFB signal tells the C86ACCP that there is a fault in the motor and then C86ACCP tell acorn and acorn display drive fault.
Everything is working, there is only one problem if any time there is any fault in my A-axis will come then C86ACCP does not know that there is something wrong.
I can make it work by just take servo drive fault signal and feed it to HLFB port but the servo fault signal work with 24v and HLFB pin of C86ACCP accept 5volt.
It would be great if somehow acorn db25 will work, i dont know why the signals are not comming in db25 port
