R3: Extended stop and retract

9.5 Examples

Motion synchronous actions
Synchronous motion actions are executed in the interpolator clock cycle. Increasing the
interpolator clock cycle, e.g. due to a high number of active synchronized motion actions,
results in a coarser time grid for evaluating trigger conditions and triggering responses for
extended stopping and retraction.

9.5.1

NC-controlled reactions

Task
The A axis is to operate as the generator drive, while the X axis should retract 10 mm at
maximum velocity in the event of a fault. The Y and Z axes should stop after a delay of 100
ms so that the X retraction axis has sufficient time to cancel the mechanical coupling.
The example is performed using NC-controlled reactions.
Only the essential parts of the entire functionality are displayed.
Requirements
The "Extended stop and retract", "Static synchronized actions" and "ASUB" options must be
set.
