Parameter 408
Number:
Data Type: REAL
P 4.2.3.2 Rotor Resistance Rr
Set the motor rotor resistance. Overwritten by AMA.
Default Value: 0.79
Parameter 409
Number:
Data Type:
REAL
Use any of the following methods for setting Rr:
Run an AMA on a cold motor. The drive measures the value from the motor. All compensations are reset to 100%.
l
Enter the Rr value manually. Obtain the value from the motor supplier.
l
Use the Rr default setting. The drive establishes the setting based on the motor nameplate data.
l
P 4.2.3.3 Iron Loss Resistance Rfe
Set the motor iron-loss equivalent resistance.
Default Value:
874
Parameter 413
Number:
Data Type: REAL
The RFe value cannot be found by performing an AMA. The RFe value is especially important in torque control applications. If RFe is
unknown, make sure to keep the default setting of the parameter.
P 4.2.3.4 Stator Leakage Reactance Xls
Set the motor stator leakage reactance. Overwritten by AMA.
Default Value: 0.03
Parameter
440
Number:
Data Type: REAL
Use any of the following methods for setting Xls:
Run an AMA on a cold motor. The drive measures the value from the motor.
l
Enter the Xls value manually. Obtain the value from the motor supplier.
l
Use the Xls default setting. The drive establishes the setting based on the motor nameplate data.
l
P 4.2.3.5 Rotor Leakage Reactance Xlr
