Fig. 6−15 State representation of positioning drive
The ECSxP position controller contains a state machine with a corresponding state control.
In each state, a related function is processed.
State changes (transitions; e.g. "EnterTrouble") take place under certain conditions.
During one program cycle, only one of the states is really active. This does not apply to the
"PosFunctions" state which is always processed in parallel.
The "Stand−by" state is of central importance since it is always activated when a state
changes to another. If you change e.g. from "Trouble" to "ManualJog", "Stand−By" will be
active for one cycle.
Use the "Enter..." transitions (see illustration) to change from "Stand−By" to another state
("Homing", "Trouble", ...) of the state machine.
Use the "Exit..." transitions to change back to the central "Stand−by" state.
