VLT AutomationDrive FC 301/302
Programming Guide
For salient PM motors: AMA is not available. If only line-line data is available, divide the line-line value by 2 to achieve the line-to-
common (star point) value. Alternatively, measure the value with an ohmmeter. This also takes the resistance of the cable into
account. Divide the measured value by 2 and enter the result.
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 1-31 Rotor Resistance (Rr)
Table 85: 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]
SynRM.
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.
r
Parameter 1-33 Stator Leakage Reactance (X1)
Table 86: 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.
