Chapter 8 Communications
8.1 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.
