Span Your Clamp and Ejector Valves
Chapter 9
9-14
We recommend that you next span the clamp close velocity (flow)
valve(s). Do this in three parts:
Revise/confirm critical values for velocity valve spanning
Span your clamp close velocity (flow) valve(s)
Test your values
Important: Many injection molding machine OEMs and hydraulic valve
manufacturers provide data regarding valve spanning (working range) for a
particular valve on their machine. If valve spanning information is
available from your OEM for your machine’s flow valve during clamp
close operations, enter the values into FCC45-48, SCC45-48, and
TCC45-48, and proceed to the section in this chapter on spanning your
Clamp Open Pressure Valve(s).
Revise/Confirm Critical Values
Over the last two chapters you entered values into configuration blocks and
profile blocks necessary to run clamp close profiles in open-loop. At this
time, review the current values of the critical settings identified below.
New parameters which need to be set are also identified. Maintain the
same configuration and profile values entered over the last two
chapters unless directed to do so otherwise in this chapter.
Verify all entries made from the previous two chapters are correct. For
Clamp Close Profiles, your current configuration should:
Disable Expert Response Compensation

(CPC04)
Select Inches (mm)/second as the Velocity Units (CPC03)
Identify the selected velocity control valve(s) (FCC02, SCC02, TCC02)
Identify Unselected Valve Set-output Values (FCC09-12, SCC09-12,
TCC09-12)
Enable Open-loop Control (CPC04)
Logically Bridge all Clamp Close Profiles (CPC03)
Disable all ramping with 0 as ramp accel and decel setpoints
(FCC17-20, SCC17-20, TCC17-20 for accel, FCC25-28, SCC25-28,
TCC25-28 for decel)
Identify velocity control limits (FCC45-46, SCC45-46, TCC45-46) and
corresponding min and max outputs (FCC47-48, SCC47-48, TCC47-48)
Identify all end-of segment position setpoints (CPC11, CPC14, CPC17,
CPC20, CPC23, CPC26, CPC29, CPC32, CPC35, CPC38)
Select Start LPC on Zone Overrun (CPC03-B11 = 0)
Identify Start LPC Position Setpoint (CPC61)
