Load Initial Configuration Values

Chapter 7

7-3

The QDC module incorporates close fast functionality with three separate
close profiles (refer to chapter 1 of this manual for more information):

First Close (FCC)
Second Close (SCC)
Third Close (TCC)

By allowing up to three separate, segmented profiles, the QDC module
increases your mold closing control flexibility. Also, the final clamp close
profile, characterized by pressure control, is Low Pressure Close (LPC).

The QDC module incorporates Break-Away Open and Open Fast
functionality through the use of three separate open profiles:

First Clamp Open (FOC)
Second Clamp Open (SOC)
Third Clamp Open (TOC)

The QDC module controls Open Slow utilizing the Clamp Open Slow
(OSC) profile. Ejector Advance (EAC) and Ejector Retract (ERC) are also
configured in this chapter.

Important:

The majority of the configuration parameters are similar from block to

block. For example, all phases need the “selected” valve identified for
pressure control, and the set-output values for all “unselected” valves
need to be identified. Because of this, worksheets for each
configuration block are found at the beginning of the chapter.

At the beginning of each configuration section, please note the control

block and words which contain this configuration parameter. After each
section is discussed, fill in values for the mentioned words in the
appropriate worksheets that follow.

The valve spanning procedure in chapter 9 of this manual requires

preset values in many of the configuration block words. The
worksheets on the following pages have many of the required initial
values already filled in for you. Other words require that you enter
values based on your machine’s specific hydraulic configuration.
