PG2 Wiring Diagram
DOS(Degradation of Signal) If the amplitude of the sine wave input of the S1-/S3/ S2-/S4 is lower than or higher than
the encoder IC's specification, a red light will be on. The possible reasons which cause this problem are the following.
1. The turns ratio of the resolver encoder is not 1:0.5 which makes the sine wave input of the S1-/S3/S2-/S4 not
equal to 3.5±0.175Vrms.
2. While motor is running, motor creates common mode noise which makes accumulated voltage to be more than
3.5±0.175Vrms
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 degree, 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 10KHz
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.
