88 SEND ALL SAMPLES UNTIL NEXT SPC OFFSET
This function tells the control to start collecting weld data for all welds.
This function should follow the SET SPC OFFSET function in the weld
schedule because it is still necessary to assign a starting bin number.
Weld data collection continues until the control executes another
schedule containing this function (without the offset function), to reset
the global data collection process.
This function overrides the global Data Collection Sample Size and
Data Collection Sample Frequency setup parameters. These are
described next.
Caution: This function is NOT designed for use in a
normal production run. It is intended for special
situations (such as tear-down) which require
continuous data collection.
SPC setup Parameters
DATA COLLECTION SAMPLE SIZE: 05 (1–99)
DATA COLLECTION SAMPLE FREQUENCY:0100 (1–9999)
These two parameters set a global command which allows the weld
control to sample data for analysis at controlled intervals.
The sample size is the amount of weld data collected for analysis
(number of consecutive welds, per bin). The sample frequency is the
total number of welds per bin, where data was collected (the samples are
taken from).
For example, by setting the Data Collection Sample Size parameter to 2
and the Data Collection Sample Frequency parameter to 8, the control
will collect weld data for 2 consecutive welds (in bin #1), and flag the
XWSS to retrieve the data. It will then collect data for 6 more cycles
(without flagging XWSS) before starting the process again.
The example table on the next page is for Bin #1 ONLY.
