Parameter 1-31 Rotor Resistance (Rr)
Table 86: Parameter 1-31 Rotor Resistance (Rr)
1-31 Rotor Resistance (Rr)
Default value: Size related
Conversion index: -4
Parameter 1-31 Rotor Resistance (Rr) has no effect when parameter 1-10 Motor Construction is set to [1] PM, non-salient SPM, [5] Sync.
Reluctance.
Set the rotor resistance value R
• Run an AMA on a cold motor. The drive measures the value from the motor. All compensations are reset to 100%.
• Enter the R value manually. Obtain the value from the motor supplier.
r
• Use the R default setting. The drive establishes the setting based on the motor nameplate data.

Parameter 1-33 Stator Leakage Reactance (X1)
Table 87: Parameter 1-33 Stator Leakage Reactance (X1)
1-33 Stator Leakage Reactance (X1)
Default value: Size related
Conversion index: -4
This parameter is only relevant for asynchronous motors.
Set the stator leakage reactance of the motor using 1 of these methods:
• Run an AMA on a cold motor. The drive measures the value from the motor.
• Enter the X value manually. Obtain the value from the motor supplier.
1
• Use the X default setting. The drive establishes the setting based on the motor nameplate data.

The parameter value is updated after each torque calibration if option [3] 1st start with store or option [4] Every start with store is
selected in parameter 1-47 Torque Calibration.
Parameter 1-34 Rotor Leakage Reactance (X2)

1-34 Rotor Leakage Reactance (X2)
Default value: Size related
Conversion index: -4
This parameter is only relevant for asynchronous motors.
Set the rotor leakage reactance of the motor using 1 of these methods:
