Note
Autonomous (emergency) operation is possible only for Motor Modules and Basic Line
Modules with article numbers that end with the code ..3, e.g. 6SL3130-6TE21-6AA3.
Principle of operation
Two task profiles are obtained for autonomous operation:
● Recognize that a component is getting into a critical state and the protective function
must be maintained.
● Restore communication with the higher-level controller.
In order to maintain the protective function, the time-slice system must remain active.
The logged-on time-slice system remains active until the protective functions signal that a
safe state has been reached and the time slices can therefore be deactivated. When
restarting the communication, if the DRIVE-CLiQ master signals that no bus timing changes
have been made with respect to the old parameterization, then synchronization is possible.
The time-slice system remains the same as before.
Note
All algorithms for autonomous operation are executed as a background process for the
component. They thus have no influence on the computer resources utilized cyclically by the
component.
Communication restart includes a topology detection during emergency operation.
Note
When the component is running in emergency mode, it cannot be deactivated.
Preparation for autonomous time-slice operation
The application signals (basic system DRIVE-CLiQ slave components) preparation for
autonomous time-slice operation. This occurs, for example, when the "armature short-circuit"
protective function is active or in chopper operation.
Changeover from normal to autonomous operation
The application activates autonomous time-slice operation. Changeover takes place
instantaneously.
Changeover from autonomous to normal operation
It is always possible to change over into normal operation without a POWER ON.
