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
