
Parameter setting examples – ACS880
Speed control using the ABB Drives – Enhanced
communication profile
This example shows how to configure a speed 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
When Reference 1 (REF1) is used, a reference value of ±20000
(4E20h) corresponds to the reference set with parameter 46.01
Speed 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.
