SUMMARY OF OBJECT DICTIONARY (OD)
For details of the object dictionary, refer to the following manual.
MR-J5-G-N1 User's Manual (Object Dictionary)
The data that a CAN application protocol over EtherCAT (CoE) device holds, such as control parameters, command values,
and feedback values, is handled as an object composed of an Index value, object name, object type, R/W attribute, and other
elements. The data is exchanged between the master and slave devices. The aggregate of these objects is called an object
dictionary (OD).
3.1
Section definition of object dictionary
With the CoE protocol (CAN application protocol over EtherCAT), objects of an object dictionary are categorized by Index
depending on the descriptions as shown in the following table. Refer to the Reference column for the details of each object.
A multi-axis servo amplifier uses one ESI file for objects of all axes. Therefore, from the second axis onward, the object
addresses (Index) differ from those of the first axis. Indexes 1000h to 1FFFh are used for common objects for all axes, and
Indexes 2000h onward are used for objects for individual axes. An individual axis can be specified by adding offsets to objects
addresses (Index).
