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), and P3-07
(Communication Response Delay Time), are optional. Please refer to Chapter 8 of this user
manual.
The followings show the content of parameter P3-00 and its corresponding address, 0300H –
0301H, which is shown in the rightmost column.

Range
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, CANopen,
and DMCNET.
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.
