model). Hold Time and the selectable Afterburst (AB) Delay parameters can be adjusted
from all three welding modes.
NOTICE
Note that, while AB Time and AB Delay are selectable, they do not have to be set. The
two parameters work in tandem - if AB Time is selected, then AB Delay must also be
selected, Afterburst is used to release workpieces that stick to the horn face after
welding.
Table 6.1 Parameter Functions
Parameters Mode Switch Function
Weld Time All Mode
sets the amount of time ultrasonic energy is
applied to the workpiece. In Collapse or
Absolute Distance Modes the weld time
parameter acts as a cycle abort condition.
Ensure Time is setup to allow for the
collapse or absolute distances to be
attained during a weld.
Collapse
Distance IW+
only
Collapse Mode
sets the amount of collapse distance
travelled from TRS while ultrasonics were
active. Note that the actual collapse
includes distance travelled during Hold
Time which, depending on your application,
may increase the weld collapse distance.
Absolute
Distance IW+
only
Absolute Mode
sets the amount of absolute distance
travelled from ULS while ultrasonics were
active. Note that the actual absolute
includes distance travelled Hold Time
which, depending on your application, may
increase or decrease the weld absolute
distance.
Hold Time All modes HOLD TIME
sets the amount of time force is applied to
the workpiece after ultrasonic energy is
turned off, and while the horn is still
contacting the workpiece.
AB Time All modes AB TIME
if selected, controls the length of time
ultrasonic energy is active after AB Delay.
Aids in dislodging a workpiece from the
horn, if necessary. Used in conjunction with
AB Delay.
AB Delay All modes AB DELAY
if selected, controls the amount of time
between the removal of force from the
workpiece and the point at which AB Time
starts. Aids in dislodging a workpiece from
the horn, if necessary, Required with AB
Time.
