What is the best way to connect AC servo (for servo motor hub) to Arduino Mega, CANOPEN/RS485?

Question

Arduino

I have two servos (servo manual - www.zlingkj.com/Upload/1602402761.pdf ) and an Arduino Mega. The question is how best to make the connection and are there ready-made examples?

There are built-in ports for CANOPEN and RS485 communication (4 pins each)

UPD.
Oh, I didn't even look at the link. Your crap is controlled by either CAN or RS485 bus. In general, the instruction is incomplete, you can look at an analogue, for example this one, it has a much more detailed manual. https://drive.google.com/file/d/1_zax1QebzwfDw8Wtz...
