Adv Process Control Sub-menu Items
The six sub-menu items and their corresponding displays
are shown (See Figure 5-41.) and described below and
on the next page:
1)
Frequency Tracking
When enabled, at the end of each cycle the operating
frequency is applied to the Free Running Frequency
setting. It’s based on a 16 point average. Therefore,
after 16 cycles, the actual operating frequency will
be the Free Running Frequency setting. If the press
has not been cycled for a minimum of 5 minutes, the
press will request that the stack be scanned in order to
verify the optimum Free Running Frequency setting.
For more information about Frequency Tracking, refer
to our
Application Note 513
on the Dukane website at:
http://www.dukane.com/us/DL_ApplData.asp
2)
Free Run Frequency
Free run is the frequency at which the press drives
the ultrasound output pulses until a valid feedback
signal is detected. Typically this value should be
below the operating frequency of the stack
Use the Scan feature to determine the optimum Free
Run Frequency.
When

down key (minus) is pressed, the next sub-menu for
