Overview of possible actions in synchronized actions

Actions in synchronized actions consist of value assignments, function or parameter calls,
keywords or technology cycles. Complex executions are possible using operators.
Possible applications include:
● Calculations of complex expressions in the IPO cycle
● Axis movements and spindle controls
● Setting data from synchronized actions can be changed and evaluated online (e.g. output
● Output of auxiliary functions to PLC
● Set-up additional safety functions
● Set superimposed movement, online tool offset and clearance control
● Execute actions in all operating modes
● Influence synchronized actions from PLC
● Run technology cycles
● Output of digital and analog signals
● Record performance recording of the synchronized actions at the interpolation cycle and
the computation time of the position controller for the loading report
● Diagnostic capabilities in the user interface
