Explicit Messaging
In many applications it is necessary to read or write parameters in the drive. This
allows increased flexibility in implementation of the machine functionality.
To allow this occasional (acyclic) data exchange of drive and motor parameters,
the drive supports explicit messaging.
The MSG instruction can read from or write to a parameter by accessing the drive's
communication object. When parameterizing the MSG instruction, below are some
important parameters:
Class = 401hex (for G120)
Instance = parameter number
p1027 = instance 1027
Attribute = parameter index number (hex) Index
Index 0 = attribute 0
Index 1 = attribute 1
...
Index 65535
Get attribute single = read a parameter
Set attribute single = write a parameter
