13. COMMUNICATION FUNCTIONS

13.2.2 Parameter setting

When the RS-422/RS-232C 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) Communication baudrate

Choose the communication speed. Match this value to the communication speed of the sending end
(master station).

Communication baudrate
0:  9600[bps]
1:19200[bps]
2:  4800[bps]

Parameter No. 16

− −

−

(2) RS-422/RS-232C serial interface selection

Select the RS-422 or RS-232C communication standard. RS-422 and RS-232C cannot be used together.

RS-422/RS-232C communication standard selection
0: RS-232C used
1: RS-422 used

Parameter No. 16

−

− −

(3) Communication 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 400μs or "1" to send back data in 400μs or
more.

Communication delay time
0: Invalid, reply sent in less than 400

µ

s

1: Valid, reply sent in 400

µ

s or more

Parameter No. 16

− − −

(4) Station number setting

Set the station number of the servo amplifier in parameter No. 15. The setting range is stations 0 to 31.
