What You Have Accomplished
The valve spanning procedure you just completed has defined the:
range of velocity available during any clamp close profile
end-of-range maximum and minimum signal levels for linear control of
the clamp velocity valve in open-loop control.
For this
range limit
When trying to obtain
the velocity in:
The QDC module drives the selected
velocity valve to % output signal in:
Minimum FCC45, SCC45, TCC45 FCC47, SCC47, TCC47
Maximum FCC46, SCC46, TCC46 FCC48, SCC48, TCC48
Now for all open-loop velocity profiles for clamp close, the QDC module
assumes a linear relationship between clamp velocity and signal output.
