By forming a mean value over several cycles, it is possible
to damp the signal, although larger variations will still be
apparent. Eff ects with diff erent cycle durations generally
only occur with non-symmetrically formed segment plates;
even diff erently aligned screw heads on a shaft can lead to
variations in cycle duration. That is why it often makes sense
to work with just one operation element per revolution at
higher rotational speeds.
Limits to the Procedure for Measuring Cycle
What happens if the rotational speed drops sharply, i. e. the
machine brakes quickly? To begin with, it is not possible to
detect any further pulses. An integrated measuring procedure
must be activated for this purpose. Even when the machine
is stopped, the frequency cannot be immediately set to 0 Hz.
In theory, the asymptotically decreasing process can take an
infi nite amount of time.
