Tune Your Machine
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.
We present this chapter in three 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 inject and clamp operations of your plastic molding process.
If your application does not require closed-loop operation, skip this
section and proceed to the section entitled Injection Tuning
Considerations for Producing Parts.
Injection Tuning Considerations for Producing Parts – We present
the usage and effect of QDC module injection parameters that require
specific considerations. We 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.
Tuning Considerations for Clamp Operation – We present the usage
and effect of other QDC module parameters for clamp operation that
require specific considerations. As with the previous section, we
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.
