396 Fieldbus control through the embedded fieldbus interface (EFB)
State transition diagram
The diagram below shows the state transitions in the drive when the drive is using the
ABB Drives profile, and configured to follow the commands of the control word from
the embedded fieldbus interface. The upper case texts refer to the states which are
used in the tables representing the fieldbus Control and Status words. See sections
