VLT® AutomationDrive EZ FC 321
Programming Guide
• 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.

• 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 1-35 Main Reactance (Xh)
Table 89: Parameter 1-35 Main Reactance (X2)
1-35 Main Reactance (X2)
Default value: Size related
Conversion index: -4
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 value manually. Obtain the value from the motor supplier.

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 1-36 Iron Loss Resistance (Rfe)
Table 90: Parameter 1-36 Iron Loss Resistance (Rfe)
1-36 Iron Loss Resistance (Rfe)
Default value: Size related
Conversion index: -3
Enter the equivalent iron loss resistance (R
performing an AMA. The R
Fe
Loss Resistance (Rfe) on default setting.
Parameter 1-37 d-axis Inductance (Ld)
Table 91: Parameter 1-37 d-axis Inductance (Ld)
1-37 d-axis Inductance (Ld)
Default value: 0.0 mH
Conversion index: -4
Enter line-to-common direct axis inductance of the PM motor. Obtain the value from the permanent magnet motor datasheet. If
only line-line data is available, divide the line-line value by 2 to achieve the line-common (star point) value. Alternatively, measure
the value with an inductance meter. This also takes the inductance of the cable into account. Divide the measured value by 2 and
enter the result. This parameter is only active when parameter 1-10 Motor Construction is set to [1] PM, non-salient SPM (Permanent
Magnet Motor) or [5] Sync. Reluctance. For a selection with 1 decimal, use this parameter. For a selection with 3 decimals, use param-
eter 30-80 daxis Inductance (Ld).
