13. COMMUNICATION FUNCTION
13.2.2 Parameter setting
When the USB/RS-422 communication function is used to operate the servo, set the communication
specifications of the servo amplifier in the corresponding parameters.
After setting the values of these parameters, they are made valid by switching power off once, then on again.
(1) Serial communication baud rate
Choose the communication speed. Match this value to the communication speed of the sending end
(master station).
Parameter No. PC21
Communication baud rate
0: 9600[bps]
1: 19200[bps]
2: 38400[bps]
3: 57600[bps]
4: 115200[bps]
(2) RS-422 communication response delay time
Set the time from when the servo amplifier (slave station) receives communication data to when it sends
back data. Set "0" to send back data in less than 800 s or "1" to send back data in 800 s or more.
RS422 communication response delay time
0: Invalid
1: Valid, reply sent in 800 s or more
Parameter No. PC21
(3) Station number setting
Set the station number of the servo amplifier in parameter No. PC20. The setting range is station 0 to 31.
