What You Have Accomplished
The valve spanning procedure you just completed has defined the:
range of velocity available during any clamp open 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
FOC45,SOC45,TOC45,OSC45 FOC47, SOC47, TOC47, and OSC47
Maximum
FOC46,SOC46,TOC46,OSC46 FOC48, SOC48, TOC48, and OSC48
Now, for all clamp-open velocity profiles, the QDC module assumes a
linear relationship between clamp velocity and signal output in open loop.
