VLT AutomationDrive FC 301/302 Programming Guide
Function:
Set the stator leakage reactance of the
motor using one of these methods:
1. Run an AMA on a cold motor.
The frequency converter
measures the value from the
motor.
2. Enter the X value manually.
1
Obtain the value from the
motor supplier.
3. Use the X default setting. The
1
frequency converter establishes
the setting based on the motor
nameplate data.
See Illustration 3.6.

1-36 Iron Loss Resistance (Rfe)
Range: Function:
Size [ 0 - Enter the equivalent iron loss
related 10000.000 resistance (R
*
Ohm] for iron loss in the motor.
The R
performing an AMA.
The R
in torque control applications. If R
unknown, leave 1-36 Iron Loss
Resistance (Rfe) on default setting.
1-37 d-axis Inductance (Ld)
Range: Function:
Size [0.0 - Enter line to common direct axis inductance
related 1000.0 of the PM motor. Obtain the value from the
*
mH] permanent magnet motor data sheet.
If only line-line data are available, divide the
line-line value by 2 to achieve the line-
common (starpoint) value. Alternatively
measure the value with an inductancemeter,
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
1-10 Motor Construction has the value [1] PM,
non-salient SPM (Permanent Magnet Motor).
For a selection with one decimal, use this
parameter. For a selection with three
decimals, use 30-80 d-axis Inductance (Ld).

1-38 q-axis Inductance (Lq)
Range: Function:
Size related [0.000 - 1000 Set the value of the q-axis

sheet.
1-39 Motor Poles
Range: Function:
Size related [2 - 128 ] Enter the number of motor poles.
