Chapter 8 Option CardsC2000 Plus
8-29
LOT (Loss of Tracking): Compare the angle of S1-/S3/S2-/S4 sine wave input to the R1-R2 cosine
wave. If their difference is more than 5 degrees, a red light will be on. Here are the possible reasons
why that happens:
1. The output frequency of the PG card is incorrect.
2. The specification of Resolver’s encoder is not 10 kHz
3. The motor creates common mode noise while it is running. That causes a big difference, while
the motor is rotating, between main winding’s cosine wave angle and the sine wave angle of
second and third windings.
