13. COMMUNICATION FUNCTION
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 or RS-422/232C
communication converter.
Personal computer
(2) Multidrop connection
(a) Diagrammatic sketch
Up to 32 axes of servo amplifiers from stations 0 to 31 can be operated on the same bus.
