11.3.2 Quadratic Curves
The deceleration curves are inverted images of the acceleration
curves and are assigned the same numbers.
Quadratic slope (curves 10 - 19)
Curve 19 is a special case compared to the other curves. The
centrifuge accelerates with maximum power. The runtime depends
solely on the moment of inertia of the rotor.
