Frequency control using the ABB Drives – Enhanced
communication profile
This example shows how to configure a frequency control
application that uses the ABB Drives - Enhanced profile. In
addition, some application-specific data is added to the
communication.
The start/stop commands and reference are according to the ABB
Drives profile. For more information, see section
communication profile
In the frequency control mode, when Reference 1 (REF1) is used,
a reference value of ±20000 (4E20h) corresponds to the reference
set with parameter 46.02 Frequency scaling in the forward and
reverse directions.
The minimum and maximum 16-bit integer values that can be
given through the fieldbus are -32768 and 32767 respectively.
