Motion synchronous actions
10.4 Actions in synchronized actions
The following applications are possible:
• Calculations of complex expressions in the IPO cycle
• Axis movements and spindle controls
• Change and evaluate online setting data from synchronized actions, such as positions,
• Output of auxiliary functions to PLC
• Setting up 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
• Diagnostic capabilities in the user interface
