ID* Fault Name Fault Descriptions Corrective Actions
68
SdRv
SpdFbk Dir Rev
Fault
Rotating direction is different from the commanding direction detected by the
sensorless.
Solution
Verify if the parameter setting of the motor drive is correct
Increase the estimator's bandwidth and verify if parameters relating to the
sensorless are correct.
69
SdOr
SpdFbk over SPD
Fault
Overspeed rotation detected by the sensorless
Solution
Verify if the parameter setting of the motor drive is correct
Increase the estimator's bandwidth and verify if parameters relating to the
sensorless are correct.
Verify if the gains of the speed circuit is reasonable.
70
SdDe
SpdFbk deviate
Fault
Big difference between the rotating speed and the command detected by the
sensorless
Solution
Verify if the parameter setting of the motor drive is correct
Increase the estimator's bandwidth and verify if parameters relating to the
sensorless are correct.
Verify if the gains of the speed circuit is reasonable.
