2.6 Glossary of Terms
The following terminology may be encountered when using or operating a 2000Xc
ultrasonic welding system.
Table 2.3 Glossary of Terms
Name Description
AB Amplitude The amplitude at the horn face during the afterburst step.
AB Delay
Time delay between the end of the hold and the start of the
afterburst.
AB Time The duration of the afterburst.
Absolute Cutoff
Ends the ultrasonic portion of the cycle when the set absolute
distance is reached.
Absolute Distance The distance the horn has traveled from home (ULS deactivation).
Absolute Mode
A mode of operation in which the ultrasonic portion of the cycle is
terminated when a user-specified distance from home has been
reached.
Absolute Position The position of the actuator after clearing the Upper Limit Switch.
Accept-as-is
A disposition permitted for a nonconforming item when it can be
established that the item is satisfactory for its intended use
without violating safety or functional requirements.
Act Clr Output
Actuator Clear output signal, sent upon the welder reaching a safe
position of the actuator return stroke.
Actual
A reported value that occurred during the weld cycle. The converse
is the set parameter that was requested during the setup.
Actuator
The unit that houses the converter, booster, and horn assembly in
a rigid mounting allowing it to move up and down either
mechanically or pneumatically to apply a predetermined pressure
on the workpiece.
Afterburst
Ultrasonic energy applied after the hold step. Used to break away
sticking parts from the tooling.
Alarm Beeper An audible signal that sounds when a general alarm has occurred.
Alarm Log
A record of alarms that have occurred to the welder. Records time,
date, alarm number, and cycle number.
Amp A
The amplitude applied to the part from the start of the weld to the
step change.
Amp B
The amplitude applied to the part from the step change to the end
of the weld.
Amp Control The ability to set amplitude digitally or by an external control.
Amplitude
The peak-to-peak movement at the horn face. Always expressed
as a percentage of the maximum.
Amplitude Graph A graph of amplitude percentage plotted against time.
