2.1 Components of synchronized actions
2.1.1

Definition of motion-synchronous actions

Defining programs
Motion-synchronous actions can be defined as follows:
• In the part program
• Static synchronized actions in an asynchronous subprogram activated by the PLC
2.1.2

Execution of synchronized actions

Conditions for execution
The actions programmed in motion-synchronous actions are executed, when:
• the synchronized action exists and has not been deselected with CANCEL(ID).
• the synchronous action is not locked, no LOCK(ID), see Chapter 2.5.1 "Coordination of
• evaluation of the action is due as a result of the programmed frequency keyword or
• the appropriate condition is fulfilled.
• For further details, please see the following subsections.
2.1.3

List of possible actions

• Output of M, S and H auxiliary functions to the PLC
• Setting (writing) of main run variables enables the following:
• Reading the MD value for the interpretation time $MD...=
• Changing of SW cam positions and times (setting data)
• Modification of coefficients and limits from FCTDEF
• Polynomial evaluation SYNFCT
• Online tool offset FTOC

– Overlaid movement ($AA_OFF), option.
– Applied tool length offsets ($AA_TOFF), option.
– Feedrate control ($AC_OVR, $AA_OVR), disabling of a programmed axis motion
– Allocate Servo–data–values $V...=
– Reading or writing arithmetic variable $R[n]=
– Writing the SD value in the main run $$SD
