R3: Extended stop and retract

6.4 Boundary conditions

6.4 Boundary conditions
Operational performance of the components
The drive components involved in the extended stopping and retraction must be capable of
functioning. If one of these components fails, the full scope of the described reaction no
longer applies. Axis-specific servo or drive alarms indicating the failure of one of these
components are also implicitly signaling that the configured stop or retract reaction of the axis
involved is no longer available or only partially.
Motion synchronous actions
Motion synchronous actions are executed in the interpolator cycle. Increasing the
interpolation cycle, e.g. due to a high number of active motion synchronized actions, results in
a coarser time grid for evaluating trigger conditions and triggering responses for extended
stopping and retraction.
