Load Initial Profile Values
Chapter 8
8-34
The valve spanning procedures in chapter 9 require these initial bit
settings. Where required, we help you select correct final values for your
application in chapter 10. For additional information, refer to the Plastic
Molding Module Reference Manual (publication 1771-6.5.88).
Velocity Setpoints
(OPC09, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39)
Use these words to configure velocity vs. position profiles. Enter velocity
in units per second. Each velocity setpoint controls the velocity of its
corresponding segment.
Select setpoints for first clamp open segments 1-3 and open slow segment
1, typical of velocities you would run during normal machine operation.
Enter these setpoints into OPC09, 12, 15, and 36 on Worksheet 8-E.
We set the remaining velocity setpoints to zero.
Pressure Setpoints
(OPC10, 13, 16, 19, 22, 25, 28, 31, 34, 37, 40)
Use these words to configure pressure vs. position profiles. Enter pressure
in PSI or Bar. Each pressure setpoint controls the pressure of its
corresponding segment.
For OPC10, 13 and 16 (first clamp open), enter pressure setpoints typical
of machine operation.
For OPC37(open slow), enter a pressure typical of machine operation.
We entered zero for the remaining pressure setpoints on Worksheet 8-E.
The valve spanning procedures in chapter 9 require these initial velocity
and pressure values. We help you select correct final values for your
application in chapter 10. For additional information, refer to Section 3 of
the Plastic Molding Module Reference Manual (publication 1771-6.5.88).
Mold Open Position Setpoint
(OPC62)
This setpoint defines the position when the clamp is fully open. The QDC
module uses it as the end of open slow position setpoint. If the clamp
reaches this position during the open slow profile, the QDC module
immediately terminates the profile and sets its outputs to OSC33-36.
To determine OPC62, we recommend you jog your clamp to its maximum
open position and observe the value in SYS27 (N40:179).
Enter this value for OPC62 on Worksheet 8-E.
