11 EtherCAT overview
EtherCAT
tem for positioning applications. EtherCAT
DS402 "drives and motion control" (drives and positioning controls). This standard
describes and defines the required objects and functions for positioning controllers.
Every EtherCAT
The objects can be divided into the two main groups – communication objects and
application objects. The objects are addressed by their index 0xnnnn (16 bit) and
sub-index 0xnn (8 bit).
11.1

Communication Objects

The communication objects are located in the index range 0x1nnn. They describe the
communication behaviour of an EtherCAT
jects comprise device information
(e. g. manufacturer's vendor-id or inverter serial number). With the help of communi-
cation objects the application objects for device control are mapped to the PDO mes-
sages.
11.2

Application Objects

The application objects are divided into two groups again. The index range 0x2000 –
0x5FFF is reserved for manufacturer specific objects and the index range 0x6nnn is
reserved for device profile specific objects. Device profile specific objects 0x6nnn are
defined by DS402 drives and motion control. They are used for controlling the device
application (start/stop, speed, motion control functions).
