1-33 Stator Leakage Reactance (X1)
Option:
Ohm
Function:
Set the stator leakage reactance of the motor
using one of these methods:
Run an AMA on a cold motor. The
1.
adjustable frequency drive will measure
the value from the motor.
Enter the X value manually. Obtain the
2.
1
value from the motor supplier.
3. Use the X default setting. The adjustable
1
frequency drive establishes the setting on the
basis of the motor nameplate data.
This parameter cannot be adjusted while
the motor is running.
1-34 Rotor Leakage Reactance (X2)
Option:
Ohm
Function:
Set the rotor leakage reactance of the motor
using one of these methods:
Run an AMA on a cold motor. The
1.
adjustable frequency drive will measure
the value from the motor.
Enter the X value manually. Obtain the
2.
2
value from the motor supplier.
Use the X default setting. The adjustable
3.
2
frequency drive establishes the setting on the
basis of the motor nameplate data.
This parameter cannot be adjusted while
the motor is running.
1-35 Main Reactance (Xh)
Option:
Ohm
Function:
Set the main reactance of the motor using
one of these methods:
Run an AMA on a cold motor. The
1.
adjustable frequency drive will measure
the value from the motor.

1-36 Iron Loss Resistance (Rfe)
Range:
1 - 10.000 Ω
Function:
Enter the equivalent iron loss resistance (R
to compensate for iron losses in the motor.
The R value cannot be found by performing an AMA.
Fe
The R value is especially important in torque

This parameter cannot be adjusted while
the motor is running.
1-37 d-axis Inductance (Ld)
Range:
0.0 - 1000.0 mH
Function:
Enter the value of the d-axis inductance. Obtain the
value from the permanent magnet motor data sheet.
This parameter is only active when par. 1-10
Motor Design has the value PM, non-salient SPM
[1] (Permanent Magnet Motor).
This parameter is available for FC 302 only.
This parameter cannot be adjusted while
the motor is running.
1-39 Motor Poles
Option:
