• True Digital Autotune with Memory (AT/M) – Provides
fully-automatic tuning and stores horn frequency at the
end of each weld.
•
Total Amplitude Control – Utilizing Branson's digital
power supply technology, you have complete control
of amplitude throughout the weld cycle: programmable
starting ramp, digital setting of weld amplitude, and
energy braking.
•
Programmable Starting Ramp – Adjustable starting
ramps from 10 milliseconds to 1.0 second to accommo-
date starting characteristics of a wide range of horns.
This feature makes it easier to start more difficult horns.
When utilizing smaller horns, you can minimize the
starting ramp reducing cycle times.
•
Auto Seek – Automatically measures stack frequency
and stores it in memory. Five selectable Auto Seek
choices are available.
•
Energy Braking – A controlled stopping of the ultrasonic
stack. This feature eliminates the traditional “ring down”
of the stack creating a more consistent energy input into
the parts. Small horns can actually be stopped faster,
increasing throughput in high-speed automation.
•
Self-diagnostics and Monitoring – Visual, audible, and
logic output alarms.
•
Multiple Weld Modes – Depending on the control level
selected, weld by time, peak power, energy, or distance
(absolute or collapse).
•
Line / Load Regulation – Corrects for variations due
to power line fluctuations and varying load conditions
through Branson's closed-loop amplitude control.
Output amplitude is maintained with a variation of only
±2% with line voltage variations of ±10%, regardless of
load, improving weld consistency (Fig. 1).
•
Password Protection – Feature for lock-out of unauthor
-
ized process changes once the equipment is set up for
a specific application.
•
Built-in Cycle Counters – Track production throughput
and alarms.
•
Selectable Pre-triggering – Auto, distance, and time.
•
System Protection Monitor (SPM) – Five levels of power
supply protection are provided: 1. Phasing, 2. Over
voltage, 3. Over current, 4. Over temperature, 5. Power
•
Automation Interface – Available for direct hookup with
PLCs and PCs. Required automation I/Os are provided
through a 24V DC logic interface.
