4.4.3 PROFIdrive State Transition Diagram
In the PROFIdrive control prole, the control bits:
•
0–3 perform the basic start-up/power-down functions.
•
4–15 perform application-oriented control.
Illustration 4.4 shows the basic state transition diagram, where control bits 0–3 control the transitions, and the corresponding
status bit indicates the actual state. The black bullets indicate the priority of the control signals, where fewer bullets indicate
lower priority, and more bullets indicate higher priority.
