Acceleration and deceleration curves

Version 11/2017, Rev. 1.7.1 of 08/12/2022 • sb
Translation of the original operating manual,
Linear 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 (spin-out).
In general, the runtime, until the set speed is reached, depends on the
moment of inertia of the rotor.
Linear curves
The slope of the fixed acceleration curves defines the time that is required
to accelerate the rotor by 1,000 rpm.
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.
Linear curve no.
