Motion synchronous actions

10.1 Basics
Programming
A synchronized action is programmed on its own in a separate block and triggers a machine
function as of the next executable block (e.g. traversing movement with G0, G1, G2, G3).
Synchronized actions comprise up to 5 command elements with different tasks:
Syntax:
DO <action1> <action2> ...
<KEYWORD> <condition> DO <action1> <action2> ...
ID=<n> <KEYWORD> <condition> DO <action1> <action2> ...
IDS=<n> <KEYWORD> <condition> DO <action1> <action2> ...
Significance:
DO
<action1>
<action2>
...
<KEYWORD>
<condition>
ID=<n>
or
IDS=<n>
560
Instruction to initiate the programmed action(s)
Only effective if the <condition> is fulfilled (if programmed).
→ See " Actions "
Action(s) to be started
Examples:
• Assign variable
• Start technology cycle
The cyclic check of the <condition> of a synchronized action
is defined using the keyword (WHEN, WHENEVER, FROM or
EVERY).
→ See " Cyclic checking of the condition "
Gating logic for main run variables
The condition is checked in the IPO clock cycle
Identification number
The area of validity and the position within the machining
sequence is defined using the identification number.
→ See " area of validity and machining sequence "
