Important: If, after attempting to tune your pressure loops using the
procedure in chapter 10, you believe your application requires the use of
dependant gain (ISA) pressure algorithms, refer to Section 3 of the Plastic
Molding Module Reference Manual (pub. no. 1771-6.5.88) for information
on this option.
Expert Response Compensation Minimum Percentage Ć Velocity
(FCC05, SCC05, TCC05, FOC05, SOC05, TOC05, OSC05, EAC05, ERC05)
The QDC module utilizes a proprietary, enhanced control scheme called
Expert Response Compensation. Expert Response Compensation (ERC)
accounts for changes in your machine, machine hydraulics, raw materials,
and other process variables. Using an exclusive algorithm, ERC adjusts
the control scheme to counterbalance changes, both abrupt upsets and long
term deviations, to your process.
Enter 1000 (10%) for each ERC Velocity Minimum Percentage. A
detailed discussion of this type of setpoint is presented in chapter 10 assist
you in selecting the correct, final values required by your application.
Refer to Section 3 of the Plastic Molding Module Reference Manual (pub.
no. 1771-6.5.88) for more information.
Expert Response Compensation Minimum Percentage Ć Pressure
(FCC06, SCC06, TCC06, LPC06, FOC06, SOC06, TOC06, OSC06, EAC06, ERC06)
A minimum Expert Response Compensation value must be entered for
pressure control algorithms just as it was for velocity control. Again, we
recommend a starting value of 10%.
Enter 1000 (10%) for each ERC Pressure Minimum Percentage. A
detailed discussion of this type of setpoint is presented in chapter 10 to
assist you in selecting the correct, final values required by your
application. Refer to Section 3 of the Plastic Molding Module Reference
Manual (pub. no. 1771-6.5.88) for more information.
