14. COMMUNICATION FUNCTION
14 - 4
14.2 Communication specifications
14.2.1 Outline of communication
Receiving a command, this servo amplifier returns data. The device which gives the command (e.g. personal
computer) is called a master station and the device (servo amplifier) which returns data in response to the
command is called a slave station. When fetching data successively, the master station repeatedly
commands the slave station to send data.
