1S-series Servo Drives with Built-in EtherCAT Communications use the object dictionary for CAN appli-
cation protocol over EtherCAT (CoE) as a base for communications.
An object is an abstract representation of a particular component within a device, which consists of
data, parameters, and methods.
An object dictionary is a data structure that contains description of data type objects, communication
objects and application objects.
All objects are assigned four-digit hexadecimal indexes in the areas shown in the following table.
1-1-3 Object Dictionary
