Drive parameter handling
With the RDNA-01, drive parameters can also be accessed. The
function is implemented by employing the so-called Explicit
Messaging properties of the DeviceNet protocol. Explicit
Messaging makes use of objects consisting of three parts,
Class,
Instance,
and
Attribute.
Class
is always 144 (90h).
Instance
and
Attribute
correspond to
the drive parameter Group and Index in the following way:
•
Instance
= Parameter Group (01…99)
•
Attribute
= Parameter Index (01…99)
For example, Parameter 99.01 is accessed as follows:
•
Class
= 144 = 0x90
•
Instance
= 99 = 0x63
•
Attribute
= 1 = 0x01.
In addition, the instance 100 (0x64) can be used to access the
data sets using explicit messaging. The first word of data set 2, for
example, can be accessed with class 0x90, instance 0x64
attribute 4. Refer to the drive firmware manual for more
information.
