4.2.5.11 Sync Stage
Set synchronization point between stages for spindle networks.
All spindles will wait on this stage until all controllers are ready to
proceed to the next stage.
Stage Timeout (s):
Total time in seconds the controller will wait in
this stage before timing out and aborting the rundown.
4.2.5.12 Thread Forming Stage
The Thread Forming PSet Strategy can be used in fastening
applications where the initial thread-forming torque is greater
than the final torque target to be left on the fastener. This
strategy is intended to be used as the first stage of a multistage
PSet, prior to the final audit stage.
The Thread Forming Strategy is a variant of the Angle Control
Torque Monitoring Stage, which, in addition, includes a reset of
the overall peak torque value when the stage completes. This
provides a way to reset the peak torque value after thread
forming so that only the peak torque from the fastening portion
of the rundown is used for the overall evaluation of the rundown
and reported.
Sequence of Operation:
The stage will run until the angle target is
reached, or is terminated early. If the stage completes
successfully, the overall peak torque is reset to the current torque
value, then the next stage in the sequence will begin. If the
stage is terminated early, or fails on the torque and angle limits,
the overall peak torque is not reset and the rundown will be
terminated.
