8.2 Communication Parameter Settings
The following describes the communication addresses for the communication parameters.
Parameters P3-00, P3-01, P3-02 and P3-05 are required to be set for any communication
between the servo drives and motors. The other optional parameters such as P3-03, P3-
04, P3-06, P3-07 and P3-08 are used depending on different customer demands and
applications.
For optional communication parameters, please refer to the Chapter 7.

X: Axis number which indicates the value must be within the range
from 0 through F.
Y: Group number which indicates the value must be within the range
from 0 to through 7
When using RS
-232/485 communication, this parameter is used set
the communication address in hexadecimal format. If the AC servo
drive is controlled by RS-232/485 communication, each drive (or
device) must be uniquely identified. One servo drive only can set one
address. If the address is duplicated, there will be a communication
fault. This address is an absolute address which represents the servo
drive on a RS-232/485 network.
Please note:
1. When the address of host (external) controller is set to 0xFF, it is
with auto-respond function. Then, the servo drive will receive from
and respond to host (external) controller both no matter the
address is matching or not. However, the parameter P3-00 cannot
be set to 0xFF.
