Design
Integrated power supply and process controller
saves space, and simplifies setup and operation
Modular component design maximizes product
flexibility and cost effectiveness by allowing the
selection of various power levels and process control
features
System upgradeability allows quick, simple field
installation of control and/or user interface features
not originally selected
Retrofittable to existing ultrasonic press systems to
bring precise process control and monitoring features
to applications already in production
19" (48cm) rack mountable version for easy system
integration at minimal cost
Universal IEC 320 power cord receptacle accommodates
most worldwide power requirements
Networking capabilities for multihead and automated
systems’ setup and monitoring through a single user
interface available
User interface options available for full-screen data
entry and parameter viewing
Compatible with current PAS presses, thrusters,
and probes
Dynamic Process Control
Powerful 32-bit RISC microprocessor addresses more
data in less time for superior performance
Real-time, multitasking operating system simultaneously
controls and monitors process parameters
One millisecond sample rate samples cycle parameters
one thousand times per second on a cycle-by-cycle basis
for greater accuracy, consistency, and control
Primary and secondary control functions offer total
flexibility in process control, reducing rejects and increasing
part consistency
Unique Dual Pressure mode increases the clamp force for
a better melt during the weld cycle, or a tighter assembly
during the hold cycle
For parts requiring more than one assembly operation and
more than one set of process parameters, Sequencing
mode automatically changes setups after a user-defined
number of process cycles
Data sampling mode allows user-selectable sample sizes
and intervals for downloading or internal storage of up to
10,000 characteristics
Nonvolatile setup memory stores 25 setups to eliminate
repetitive setup procedures and conveniently accommodate
multiple projects
Built-in serial and parallel communications ports for realtime
interfacing to external devices such as a printer for
permanent documentation, an optional user interface for
full-screen display, or another computer for additional
data storage or statistical process control (SPC) analysis
Self-diagnostic error messages simplify troubleshooting
and correcting setup and programming mistakes
Front Panel Interface
Four line by twenty character LCD display shows cycle
data and setup information using terms that are easy to
understand
Twelve-button keypad with one touch “Hot Keys ” makes
programming and parameter entry, selection, or modification
fast and easy
System power output indicates normal or possible
overload operating condition during the weld cycle
Auxiliary outputs provide automation-ready signals, such
as ready out, part limit status, in dwell, and part status, for
flexible, easy system integration with automated machinery
and PLCs
Programmable bad part limits indicate all parameters
outside the tolerance established for an acceptable part
Programmable suspect part limits indicate parameters in a
range that would cause a part to be suspect
User-activated limit indicators label bad and suspect
parts on printouts and an optional user interface showing
out-of-tolerance parameters
Bad part audible and/or electronic alarm alerts the
operator to any reject parts without having to look at the
user interface
Separate suspect part audible and/or electronic alarm
tells the operator to set the part aside for inspection
On-screen, real-time power, distance, optional force and
pressure, and time graphic output for immediate analysis
or documentation of assembly process data (requires an
optional user interface)
Frequency and power displays for checking and monitoring
acoustic stack characteristics
Optional remote setup switching allows setup selection in
response to a keyed fixture or a PLC signal, minimizing
changeover time and increasing productivity
Programmable pressure profiling and force by interface
with the electronic pressure regulator, pressure transducer,
and load cell press options offer increased control,
repeatability, and consistency
System status panel displays any of six self-diagnostic
messages, including Fault, Input Test, Overload, On Line,
Overtemperature, or Off Line
Distance Module and Linear Encoder
Weld by distance mode controls the melt collapse
distance to insure that the same volume of material melts
on each part so that the finished joint strength is consistent
Weld by absolute distance mode controls the finished part
height to yield uniform assemblies
All distance parameters (downstroke, trigger delay, weld,
hold, absolute weld, total weld, and total stroke distances)
are monitored, with upper and lower limits for bad and
suspect parts to verify quality and consistency
High quality linear optical encoder with a one-micron
resolution for excellent precision and repeatability
Graphing capability for plotting a Distance vs. Time curve
on every weld, either on an optional user interface or a
serial or parallel printer
Power and Energy Module
Weld by peak power mode terminates ultrasound when
the available joint material is completely melted, compensating
for variations in the molded part
Weld by energy mode delivers a specific amount of
energy to the work to enhance process control
Monitors all power and energy parameters with upper
and lower limits for bad and suspect parts
System power output indicates normal or possible
overload operating condition during the weld cycle
System status panel displays any of six self-diagnostic
messages, including Fault, Input Test, Overload, On Line,
Overtemperature, or Off Line
Graphing capability for plotting a Power vs. Time curve
on every weld, either on an optional user interface or a
serial or parallel printer
