14.2.1 Communication overview

This servo amplifier is designed to send a reply on receipt of an instruction. The device which gives this
instruction (e.g. personal computer) is called a master station and the device which sends a reply in
response to the instruction (servo amplifier) is called a slave station. When fetching data successively, the
master station repeatedly commands the slave station to send data.
