Chapter 8 MODBUS CommunicationsASDA-AB Series

8.2Communication Parameter Settings

The following describes the communication addresses for the communication parameters.

For communication parameters, please refer to the Chapter 7. Communication Addresses 0301, 0302, and 0305 have to be set identically for all the drives and devices to communicate correctly.

0300H

Default: 1

Communication

Range: 1~254

Address Setting

 

 

 

If the AC servo drive is controlled by RS-232/485/422 communication, each drive (or device) must be uniquely identified and addressed between 1 and 254. Access to program this number is via parameter P3-00.

0301H

Default: 1

Transmission

Range: 0~5

Speed

Settings:

 

0: Baud rate 4800 (data transmission speed: bits / second)

 

1: Baud rate 9600 (data transmission speed: bits / second)

 

2: Baud rate 19200 (data transmission speed: bits / second)

 

3: Baud rate 38400 (data transmission speed: bits / second)

 

4: Baud rate 57600 (data transmission speed: bits / second)

 

5: Baud rate 115200 (data transmission speed: bits / second)

 

 

This parameter is used to set the desired transmission speed between the computer and AC servo drive. Users can set this parameter and control transmission speed to reach the maximum baud rate of 115200 bps.
