9.2 RS-485 / RS-232 Communication Parameters Setting
The following four parameters, P3-00 (Address Setting), P3-01 (Transmission Speed), P3-02
(Communication Protocol) and P3-05 (Communication Mechanism), are essential and must be set
for the communication of the servo drive. The rest, such as P3-03 (Communication Error Disposal),
P3-04 (Communication Timeout), P3-06 (Control Switch of Digital Input), P3-07 (Communication
Response Delay Time) and P3-08 (Monitor Mode) is optional. Please refer to Chapter 8 of this user
manual.

When using RS-232/RS-485 to communicate, one servo drive can only
set one address. The duplicate address setting will cause abnormal
communication.
This address represents the absolute address of the servo drive in
communication network. It is also applicable to RS-232/485 and CAN
bus.
When the communication address setting of MODBUS is set to 0xFF,
the servo drive will automatically reply and receive data regardless of
the address. However, P3-00 cannot be set to 0xFF.
