Brief description

Definition of synchronized actions
Motion-synchronous actions (or "synchronized actions" for short) are instructions
programmed by the user, which are evaluated in the interpolation cycle of the NCK in
synchronization with the execution of the part program. If the condition programmed in the
synchronized action is fulfilled or if none is specified, then actions assigned to the instruction
are activated in synchronism with the remainder of the part program run.
Applications
The following selection from the wide range of possibilities indicates how actions
programmed in synchronized actions can be usefully employed.
• Output of auxiliary functions to PLC
• Writing and reading of main run variables
• Positioning of axes and spindles
• Activation of synchronous procedures, such as:
• Activation of technology cycles
• Online calculation of function values
• Online tool offsets
• Activation/deactivation of couplings/coupled motion
• Take measurements
• Enabling/disabling of synchronized actions
All possible applications of this function are described in the "Detailed Description" chapter.
