LOS (Loss of Signal)
Sin/Cos Winding is Open Circuit or Has Many Shorted Turns
DOS (Degradation of Signal)
Sin/Cos winding has some shorted turns then, Large Magnitude variation
Excitation winding has shorted turns then Magnitude > maximum allowable
input voltage
LOT (Loss of Tracking)
Tracking Error > 5 º, Step change in Speed, Speed too high etc.
