8.1.2 Signal monitoring

The graphic above shows a Lissajous figure of the SinCos
signals. With optimal signals, the figure is an optimal circle
having the diameter of the amplitude (unit circle). The limits to
be monitored are shown in gray, so that all error presump-
tions according to EN 61800-5-2 can be detected.
Requirements
To make sure that all unit circle quadrants are passed
through and that there is no hold error (stuck-at-fault), the
number of periods of the sine signal must be equal to the
number of periods of the cosine signal.
The minimum and maximum limits of the Lissajous figure
must be monitored in a way suitable for the application.
Chapter Technical Data [} 42] lists the technical characterist-
ics of the SinCos output.
