Adv Process Control Sub-menu Items
The six sub-menu items and their corresponding displays
are shown (See Figure 5-61.) and described below and
on the next page:
1) Phase Shift
Phase shift is used to adjust the timing of the ul-
trasound output driving pulses. A positive number
delays the start of the output pulses and a negative
number causes the signal output to start earlier.
Phase Shift range is + 20° to - 20°
2) Free Run Freq
Free run is the frequency at which the generator
drives the ultrasound output pulses until a valid
feedback signal is detected. Typically this value
should be below the operating frequency of the stack
Adjust manually within the prescribed limitations
for your particular generator model.
3) Freq Lock and Hold
When frequency lock and hold is disabled the
frequency of the stack is tracked by changing the
frequency of the ultrasound driving pulses to match
the feedback signal frequency.
When enabled the frequency of the feedback is
tracked until lock is achieved then it is ignored and
the ultrasound output remains at a fixed frequency
until the end of the weld.
Enable or Disable this feature.
Moving to the Next Sub-menu
When > is next to RAMP DOWN TIME, and the
down key (minus) is pressed, the next sub-menu
for System Status IO replaces the Adv Process
Control sub-menu.
