The start sequence for the parameter example above is given below.
Control word:
•
Reset the fieldbus communication fault (if active).
•
Enter 47Eh (1150 decimal) -> READY TO SWITCH ON.

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
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.
