6.2.5 Autotune
The Autotune function is used to determine the exact horn frequency
automatically. The Autotune function consists of two individual
functions:
• Auto-Seek
An ultrasonic test signal is applied to the acoustic stack once per
minute. This way, the current resonant frequency of the horn is
determined regularly which may change due to heat expansion.
• Autotune/Memory
After completion of each faultless weld cycle the frequency of the
horn is automatically stored for the next weld.
