FB Processdata Input mapping in application
In addition to sending control commands and speed reference values to the application, 8 process
data items can be sent directly to the application to control other features via fieldbus. These can
be, for example, activating preset frequencies, activating or deactivating faults, selecting different
ramp times, controlling I/O's, and so on. Different applications support different features. For more
information, see the application manual. Also, always check the value of the sent data in the appli-
cation manual to see in which format they are given (for example, % values, bit coded values, and
so on).
