Before MC_BR_RegMarkCapture001 can be used, the feed axis must be set to the registration mark being used. The function block then uses the next valid trigger (i.e. registration mark) at the configured location as its reference (or according to the configuration in "ProductParameters").
A MC_BR_EventMoveXxxxx or MC_BR_MoveXxxxxTriggStop function block can be used to set up the procedure. These function blocks make it possible to specify an additional specific distance to be covered or a defined position to be traversed after a trigger signal has arrived.
A LATCH SPT function block can be used if trigger width evaluation is necessary during setup. To do this, the "LATCH_STATUS" output of the SPT function block must be used as the "EventInput.EventSourceParID" of the MC_BR_EventMoveXxxxx function block.
Information:
•Width evaluation (LATCH_EV_WIDTH_MIN, LATCH_EV_WIDTH_MAX) must be specified in axis units.
•The "LATCH_STATUS" output is only set after the falling (i.e. second) edge (after a valid trigger has been detected).
The feed axis does not have to be set up in this mode. The first valid trigger is used as a reference point for subsequent measurements.
