8.2 Communication Parameter Settings

The following describes the communication addresses for the communication parameters.
For communication parameters, please refer to the Chapter 7.

Communication
Address Setting
When using RS-232/485 and CANbus 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 duplicate, there will be a communication
fault. This address is an absolute address which represents the servo drive on a RS-
232/485 or CANbus network. 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.
