Communication services
The master communicates with the object dictionary via the interface and use of the
communication services (see chap. 3.2, p. 15). The communication services are based on
CANopen device systems.
Object Dictionary
The object dictionary contains parameters, set values and actual values of a drive. The
object dictionary is the link between the application (drive functions) and the
communication services. All objects in the object dictionary can be addressed by a 16-bit
index number (0x1000 to 0x6FFF) and an 8-bit sub-index (0x00 to 0xFF).
Index
Assignment of the objects
0x1000 to 0x1FFF
Communication objects
0x2000 to 0x5FFF
Manufacturer-specific objects
0x6000 to 0x6FFF
Objects of the drive profile to CiA 402
The values of the parameters can be changed by the communication side or by the drive
side.
Application part
The application part contains drive functions corresponding to CiA 402. The drive
functions read parameters from the object dictionary, obtain the setpoints from the
object dictionary and return actual values. The parameters from the object dictionary
determine the behaviour of the drive.
No further details of the application part are given in this document. The
communication with the drive and the associated operating modes are described in
the separate “Drives Functions” manual.
