5 SDO (Service Data Object) COMMUNICATION

5.1 SDO communication-related services

SDO (Service Data Object) COMMUNICATION

In SDO (Service Data Object) communication, object data can be transmitted and received asynchronously between a master
station (controller) and a slave station (servo amplifier).

5.1

SDO communication-related services

The servo amplifier supports the following services related with SDO communication.

Services

Description

SDO Download Expedited

This service writes data of up to 4 bytes to the slave station.

SDO Download Normal

This service writes data of the specified bytes to the slave station.
