Autotune Mode; Current Amplitude - Dukane VWA-4300 User Manual

Linear Vibration Welder 4000 Series, Model VWA User's Manual

Autotune Mode

Use this feature to automatically determine the resonant
frequency of the vibrating Assembly.
(The upper assembly includes the swing frame, carriers
and tooling.)
Before using the Autotune feature, attach the upper tool-
ing securely to the swing frame and torque it to specifica-
tions. The linear vibration welder frequency is nominally
220 Hz.

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.

The acceptable frequency range is 200

NOTE
If Autotune is performed with no upper
tool installed, the machine will alarm. This
alarm can only be cleared after a success-
ful Autotune is done.
(An acceptable frequency range was reached,
and the upper tool is installed.)
NOTE
Why use Auto-Ping?
Under certain conditions, the tempera-
ture of some welder parts may vary over
time resulting in changes to the resonant
frequency of the tool. With auto-ping the
welder automatically compensates for these
changes by periodically measuring the
resonant frequency. It then sets the welder
running frequency to match it.
Benefits: welder parts run cooler, and there
is reduced energy use. This results in lower
stresses to welder parts and extends equip-
ment life.
