Parameter 1-34 Rotor Leakage Reactance (X2)
Table 87: Parameter 1-34 Rotor Leakage Reactance (X2)
1-34 Rotor Leakage Reactance (X2)
Default value: Size related Parameter type: Range, 0.0400 - 400.0000 Ohm Setup: All setups
Conversion index: -4 Data type: Uint32 Change during operation: False
N O T I C E
This parameter is only relevant for asynchronous motors.
Set the rotor 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
2
value manually. Obtain the value from the motor supplier.
Use the X
2
default setting. The drive establishes the setting based on the motor nameplate data.
N O T I C E
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 1-35 Main Reactance (Xh)
Table 88: Parameter 1-35 Main Reactance (Xh)
1-35 Main Reactance (Xh)
Default value: Size related Parameter type: Range, 1.0000 - 10000.0000 Ohm] Setup: All setups
Conversion index: -4 Data type: Uint32 Change during operation: False
N O T I C E
This parameter cannot be adjusted while the motor is running.
N O T I C E
Parameter 1-35 Main Reactance (Xh) does not have effect when parameter 1-10 Motor Construction is set to [1] PM, non-salient SPM .
Set the main 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
h
value manually. Obtain the value from the motor supplier.
Use the X
h
default setting. The drive establishes the setting based on the motor nameplate data.
N O T I C E
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 .
