6.2.3 Amplitude Control
Depending on the internal DIP switch settings (please refer to chapter
6.2.6), you can reduce the amplitude by up to 50 % with respect to the
maximum amplitude as follows:
• Using an external control. This control action is a continuous
adjustment during the welding process.
• Using the potentiometer located on the front, please refer to chapter
4.6.1.
This type of control is suitable for applications where
• materials difficult to process are used,
• an amplitude is required that is in between the gain ratios of two
different boosters.
6.2.4 Ramp Start (Soft Start)
A ramp function improves the start behaviour and the start time.
• Start behaviour
The system adapts itself automatically to different horn shapes and
pressure conditions.
The start behaviour is improved and the stress on the components
of the acoustic stack is reduced.
• Start time (settling time)
The start time can be adapted to the weld time.
Example: With a weld time of only 50 ms, a start time of 105 ms
would be unproportionally long. On account of the ramp function the
start time can be reduced to 10 ms.
The four start times 10, 35, 80 and 105 ms are adjusted using DIP
switches (please refer to chapter 6.2.6).
