is terminated at a predetermined point in the stroke, measured from the
top of the stroke. In collapse, the weld is terminated at a predetermined
point in the stroke after the horn contacts the part and the trigger switch is
activated. The position display is digital. With position modes, upper and
lower limit ranges may be selected.
• Digital parameter entry with autoranging - when entering parameters
gives precise settings for repeatable accuracy. The autoranged values enable
fine resolution and setup accuracy.
• A linear optical encoder - (IW+ models only) measures weld “distance.”
The resolution on the encoder is 0.0001 inch (0.0025 mm).
• Afterburst with variable delay and duration - is available to dislodge a part
or material adhering to the horn face.
• Individual select keys - allow easy selection of parameters to be modified.
Active choice is lighted.
• Sequence of operation - is displayed in the digital LED window during the
welding cycle.
• Self-diagnostics and cycle monitoring - features and capabilities provide
fast, accurate troubleshooting and minimize downtime. During initial power-
up, the unit completes a self-check and identifies any fault conditions or
parameter errors before indicating that the system is “ready” for operation.
• Visual and audible alarms, and external outputs - identify overload,
machine faults and setup errors (e.g., emergency stop engaged).
• Fast-response LED storage meter - displays power loading in 5% incre-
ments, and provides storage of the peak power achieved during the weld
cycle as well as better visibility; 100% of rated output of the power supply
is delivered at full meter reading.
• Peak power reading - from the last welding cycle is available on the digital
LED display by depressing the “reset” switch. Similarly, power in the tuning
mode is digitally displayed when the “test” switch is depressed.
• LED readouts display parameter settings - during setup and operation
for easy reference and monitoring. LEDs are large and easy to read in most
light conditions.
• Lockout of front panel switches - is provided by and internal dip switch,
preventing unauthorized parameter changes to the setup.
• Nonvolatile storage of cycle parameters - provides storage of last-used
cycle parameters even if the system is shut off or a power interruption occurs.
2000 Series
Equipment
Standard
Features
• Autotune plus Memory (AT/M) -
Provides fully-automatic tuning in a
range of + 500 Hz centered around
19.950 kHz for 20 kHz horns and
stores horn frequency at the end of
each weld cycle.
• System Protection Monitor (SPM) -
Five levels of power supply protection
are provided: 1) phasing, 2) over volt-
age, 3) over current, 4) over tempera-
ture, and 5) power. The benefits of
this feature are to avoid equipment
failures and to provide greater weld
accuracy and repeatability.
• Automatic pretriggering - is avail-
able to provide pretriggering without
a mechanical switch to wear, adjust,
or fail.
• Dynamic Triggering - provides con-
sistent weld quality by initiating (trig-
gering) ultrasonic vibrations after a
preset force, ranging from 15-200 lbs.
(67 - 890 N), is applied to the part.
As melting of the plastic occurs,
dynamic follow-through ensures the
smooth, efficient transmission of ultra-
sonic energy into the part by maintain-
ing horn/part contact and force. The
range of dynamic follow-through is
from 15 - 200 lbs. (67 N to 890 N). The
Dynamic Trigger mechanism of the
2000 Series includes a 48 position con-
trol dial for greater accuracy and con-
