13. COMMUNICATION FUNCTION 

POINT 

 

The USB communication function (CN5 connector) and the RS-422 
communication function (CN3 connector) are mutually exclusive functions. They 
cannot be used simultaneously. 

 

 
Using the serial communication function of RS-422, this servo amplifier enables servo operation, parameter 
change, monitor function, etc. 
 
13.1 Configuration 

(1) Single axis 

Operate the single-axis servo amplifier. It is recommended to use the following cable.

Note 1. The BMJ-8 (Hakko Electric Machine Works) is recommended as the branch connector. 

2. The final axis must be terminated between RDP (pin No.3) and RDN (pin No.6) on the receiving side (servo amplifier) with a 

150  resistor.
