Chapter 9 Communications
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.
RS-232
Configuration
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.
