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, clamp, and eject 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 and Eject Operations –
We present the usage and effect of other QDC module parameters for
clamp and eject operations 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.
