Upper Limit
The feedback voltage upper and lower limits can be used for automatic Material
supply disruptions detection of the winding application, which represent the upper and
lower bounds of the Material supply disruptions, respectively. Due to the particularity of
the winding application, F09.35 and F09.36 can be Used to reflect the real sensor
boundaries, which is more conducive to system stability.
