11.3 Acceleration and Deceleration Curves
11.3.1 Linear Curves
The slope of the fixed acceleration curves defines the time that is
required to accelerate the rotor by 1,000 rpm.
Linear as well as quadratic curves are numbered in the direction of
increasing acceleration (from right to left).
The deceleration curves are inverted images of the acceleration
curves and are assigned the same numbers. An exception is curve 0.
It decelerates brakeless.
In general, the runtime, until the set speed is reached, depends on
the moment of inertia of the rotor.
Linear slope (curves 0 - 9)
Curve 9 is a special case compared to the other curves. The
centrifuge accelerates with maximum power. The runtime, until the
set speed is reached, depends solely on the moment of inertia of the
rotor.
