Load Initial Profile Values
Chapter 8
8-9
-IPC64 determines the position at which the QDC module begins to
allow pressure transitions. A non-zero value measured from the mold
end forces the QDC module NOT to transition on pressure until the
ram (screw) reaches this position. A zero setpoint forces the QDC
module to use any non-zero setpoint in IPC62 or IPC63 over the
entire injection profile.
We recorded zero on Worksheet 8-A to inhibit this function.
The valve spanning procedures in chapter 9 require these initial values.
We help you select the correct final values required by your application in
chapter 10. For additional information, refer to the Plastic Molding
Module Reference Manual (publication 1771-6.5.88).
After you determine initial values and record them on Worksheet 8-A,
you are ready to proceed.
1.
Enter all worksheet values into your PLC-5 data table.
Important: Be sure that you have not altered any setpoints, and that you
have entered each and every setpoint exactly as on the worksheet.
2.
Use the procedure described in chapter 4 to download command
blocks to the QDC module. We repeat the IPC block download data.

Check SYS61 and SYS62 for programming errors. Correct as needed.
Use Worksheet 8-B to enter setpoints for a ram (screw) pressure vs. time
pack/hold profile. The valve spanning procedures in chapter 9 require
specific values. We have already entered many values for you, and help
you determine other values in the text that follows.
