Linear Vibration Welder 5000 Series
Autotune Mode
Use this feature to automatically determine the resonant
frequency of the vibrating Assembly.
(The upper assembly includes the springs, carriers and
tooling.)
Before using the Autotune feature, attach the upper tooling
securely to the springs and torque it to specifications. The
linear vibration welder frequency is nominally 220 Hz.
When Autotune is complete, a message is displayed.
Touch this button
to turn Auto-Ping
OFF and ON.
Touch this button
to reset the Auto-
Ping counter.
Weld Amplitude – See Operate view > Weld Amplitude.
Frequency – See Operate view > Frequency.
Current Amplitude – This is the amplitude at the moment
the Autotune or Run Tool tests are made.
Q Factor -. The current Q Factor value.
Stored Q Factor - The Q Factor value from the last saved
setup. This can be useful when changing tools back and
forth to verify the Q Factor value is relatively the same
as before.
Auto-Ping - When on, this feature automatically does an
Autotune after a selected number of cycles are completed.
The operator sets the counter with a preset range between
1 and 300 cycles.

NOTE
The acceptable frequency range is
195 Hz – 240 Hz.
NOTE
If Autotune is performed with no upper
tool installed, the machine will alarm.
This alarm can only be cleared after a
successful Autotune is done.
(An acceptable frequency range was
reached, and the upper tool is installed.)
NOTE
What is Q Factor?
It is the system's resonance quality fac-
tor. It is used to determine how quickly
a weld fixture's amplitude decays. If a
tool has been changed, this value can
be used to detect changes in the sys-
tem from the previous time the tool was
used. Problems with springs or loose
bolts may account for changes in
