4.5.1 Communication connection with servo host computer (RS422)
Servo drives communicate with the host computer via RS422 communication. A USB to RS422 (RJ45
connector) cable is required for communication, and you need to equip it by yourselves.
(1) VD2A&VD2B
VD2A and VD2B servo drives communicate with the host computer via the CN3 interface by RS422
