Drive parameter object, Class 90h
With FDNA-01, drive parameters can also be accessed via explicit
messaging. Explicit messaging makes use of objects consisting of
three parts: class , instance and attribute .
Note: When using the Drive parameter object to update the
fieldbus configuration groups, changes to the fieldbus configuration
will only take effect when the module is powered up the next time
or when a ‘Fieldbus Adapter parameter refresh’ is given.
Class is always 144 (90h). Instance and attribute correspond to the
drive parameter group and index in the following way:
For example, parameter 99.01 is accessed as follows:
22 Speed
Scale
Get, Set Speed scaling factor. See
parameter description
10 ODVA

24 Torque
