Start LPC Position Setpoint (CPC61)
This clamp position is used by the QDC module as protection against
running a Clamp Close Profile into the Mold Protection Zone. If this
position is reached while the QDC module is executing any of the first
three Clamp Close Profiles, the QDC module immediately terminates
execution of the ongoing Clamp Close profile and either:
begins Low Pressure Close
sets its outputs to zero (depending on the state of CPC03-B11, the Mold
Protection Zone Overrun Bit)
Enter a value for the Start LPC Position Setpoint that corresponds to a safe
distance away from Mold Safe (CPC62). We recommend an initial value
significantly larger than the Start LPC Position Setpoint you would
typically use during normal machine operation. A detailed discussion of
this setpoint is presented in chapter 10 to assist you in selecting the correct,
final value required by your application. Refer to Section 3 of the Plastic
Molding Module Reference Manual (pub. no. 1771-6.5.88) for more
information.
End-of Segment Position Setpoints
(CPC11, CPC14, CPC17, CPC20, CPC23, CPC26, CPC29, CPC32, CPC35,
CPC38)
C onfigure only the first clamp close profile segments. Enter values for
segments of second, third, and low pressure close profiles equal to zero
(CPC20, CPC23, CPC26, CPC29, CPC32, CPC35, and CPC38 should all
be zero). Determine End-of Segment Position Setpoint Values for first
clamp close as follows:
Jog the mold to its full open position and observe the value in SYS27
(Pro-Set 600 address N41:179). Subtract the value you entered for
Start LPC Position Setpoint (CPC61) from SYS27. Divide this
difference into three equal sections. The dividing line of each section
should be entered into the end-of-segment position setpoints for
segments 1, 2, and 3.
Important: Keep in mind that these positions are all absolute distances
measured from zero. Refer to Section 3 of the Plastic Molding Module
Reference Manual (pub. no. 1771-6.5.88) for more information.
