When the ultrasonic supply is READY a timer is started to generate the 50
ms impulse command in rung 0. When the timer is finished it will be reset by
rung 0001 so it will be ready to go as soon as the cycle is completed and
ready returns true.
While the timer is timing, output O:3/0 is set causing the ultrasonic system
to begin a new cycle. This is the 50 ms impulse signal (rung 0002).
Once the new cycle has started, the ready signal will be false and the next
job number is sent to the output at output O:1.0. So the address code for the
next cycle is set and stable long before the present cycle is completed (rung
0003).
Rung 0004 generates the next job address code and updates the holding
register, N7:2, with the next job number. If the number is greater than 15, it
gets reset to 1 to start over.
This sample runs round and round as fast as possible limited by the
application time settings, the ultrasonic press movement (gap to the fixture
and parts) and travel distance. Over 80 weld cycles per minute are possible
with very short weld times, higher pressures and shorter press stroke
settings.
