Index Pulse & Length Thresholds
The Index Pulse and Length Thresholds can be used to control a cutter and
provide pre-cut queues to the process control system so, for example, the line
can be slowed prior to a cut. The Index Pulse is configured to trigger at a
specified length interval, and the Length Thresholds can be configured to
trigger at preset lengths before the Index Pulse triggers. The Length
Threshold outputs remain high until the Index Pulse triggers and resets. The
index pulse automatically resets the Length Threshold outputs—no external
wiring is required.
Another way to reset these outputs is to set the Index Pulse Setting to a high
value and reset the threshold outputs by asserting the Length Reset Input.
The Length Thresholds are available as an alternate output function of the
User Scaleable Pulse Output.
Example:
Setting Value
Index Pulse Setting 100 m
Index Pulse Length 100 ms
Length Threshold A 90 m
Length Threshold B 80 m
