Chapter 9 Communication
9.1 RS-485 / RS-232 Communication Hardware Interface
This servo drive supports the serial communication of RS-485 and RS-232. Communication
function enables the servo drive to access and change parameters inside the system.
However, RS-485 and RS-232 cannot be used at the same time. Parameter P3-05 can use
RS-485 and RS-232 as the communication protocol. Followings are the wiring description.

NOTE
1)
15-meter communication cable is suitable for less interference
environment. If the transmission speed is over 38400bps, the
length of communication cable should be shorter than 3 meters
so as to ensure the accuracy of transmission.
2)
Numbers shown in the above diagram represent the pin number
of each connector.
