Ejector Forward Dwell Timer Preset (EPC57)
The QDC module starts an internal Ejector Forward Dwell Timer
dependent upon the state of EPC03-B15.
Enter 0 for the Ejector Forward Dwell Timer Preset. For additional
information 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).
Ejector Strokes Required (EPC64)
The QDC module uses this entry as a counter preset to determine how
many times the ejector position must attain one of its advanced positions
(EPC59 or EPC29) during the Ejector Profile before the QDC module is
allowed to initiate the final “full retract” portion of the Ejector Profile.
A zero entry inhibits the entire Ejector Profile.
Enter 1 for Ejector Strokes Required. The valve spanning procedures
presented in chapter 9 require this initial value. For additional information
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).
