AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
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
Index (hex) Area Description
0000 to 0FFF Data Type Area Definitions of data types.
1000 to 1FFF CoE Communications Area Definitions of objects that can be used by all serv-
ers for designated communications.
2000 to 2FFF Manufacturer Specific Area 1 Objects with common definitions for all OMRON
products.
3000 to 5FFF Manufacturer Specific Area 2 Objects with common definitions for all 1S-series
Servo Drives (servo parameters).
