Tune Your Machine for Producing Parts
In chapter 9 you ran simple open-loop profiles to span your valves. This
chapter presents guidelines to help you adjust parameters in configuration
and profile blocks to optimize machine performance for production runs.
In this chapter, we consider the following items not covered previously.
closed-loop tuning
part tuning parameters that require specific considerations
We present this chapter in two major sections:
Closed-loop Tuning – We discuss the usage and effect of the QDC
module’s PID gain constants, and procedures to determine proper gain
settings for your plastic molding process. If your application does not
require closed-loop operation, skip this section and proceed to the
section entitled Part Tuning Considerations.
Tuning Considerations for Production Parts – We discuss the usage and
effect of other QDC module parameters. We present this section in a
discussion rather than a procedural format. The discussions assume you
are familiar with conventions, terminology, and procedures used in the
Injection Molding Industry, this manual, and the Plastic Molding
Module Reference Manual (publication 1771-6.5.88).
