15. COMMUNICATION FUNCTIONS

This servo amplifier has the RS-422 and RS-232C serial communication functions. These functions can be
used to perform servo operation, parameter changing, monitor function, etc.
However, the RS-422 and RS-232C communication functions cannot be used together. Select between RS-
422 and RS-232C with parameter No.16. (Refer to section 15.2.2.)
