P 4.2.3.2 Rotor Resistance Rr
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
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
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
Use any of the following methods to set Xlr:
Run an AMA on a cold motor. The drive measures the value from the motor.
l
Enter the Xlr value manually. Obtain the value from the motor supplier.
l
Use the Xlr default setting. The drive establishes the setting based on the motor nameplate data.
