Motion synchronous actions

Structure, basic information

10.1
Function
Synchronized actions allow actions to be executed such that they are synchronized to
machining blocks.
The time at which the actions are executed can be defined by conditions. The conditions are
monitored in the interpolation cycle. The actions are therefore responses to real-time events,
their execution is not limited by block boundaries.
A synchronized action also contains information about its service life and about the
frequency with which the programmed main run variables are scanned and therefore about
the frequency with which the actions are started. In this way, an action can be triggered just
once or cyclically in interpolation cycles.
Possible applications:
• Optimization of runtime-critical applications (e.g. tool changing)
• Fast response to an external event
• Programming AC controls
