8.2 RS-485 / RS-232 Communication Parameter Settings
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 7 of this user manual.
The following table shows the contents of parameter P3-00. The corresponding
communication address is 0300H ~ 0301H as shown in the right column.

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.
