11.1 General information

11.1.1 Internal state machine

The execution of the different basic functions is internally controlled by a state machine which can

adopt the following "function states":

[11-1] Function states of the state machine "Basic functions"

The state machine ensures that:

• one basic function at a time adopts the control of the drive.

• only the basic function with the highest priority (= smallest number) is executed if several basic

functions are activated at the same time.Priorities

( 378)

• the drive always has a defined state both in case of error and in normal operation.
