Sorry if I put this new tread in the wrong place.

So my name is Luis I'm from Brazil, I have a big problem with brother cnc TC731, the spindle motor and driver is damaged and I can't find the spare parts for that machine here in Brazil. I have a Siemens driver and motor in good conditions. I would like to adapt it in the machine, has someone already did it or something similar?
Another problem, the electrical diagram doesn't has the information about the communication between cnc and spindle driver, pins information. Maybe someone has it to send me, I appreciate a lot.

Thanks for some help.
