Range: Function:
measure the value from the
motor.
2. Enter the X
1
value manually.
Obtain the value from the
motor supplier.
3. Use the X
1
default setting. The
frequency converter establishes
the setting on the basis of the
motor name plate data.
See Illustration 3.6.

Range: Function:
Size
related*
[ 0.0400 -
400.0000
Ohm]
Set the rotor leakage reactance of the
motor using one of these methods:
1. Run an AMA on a cold motor.
The frequency converter will
measure the value from the
motor.
2. Enter the X
2
value manually.
Obtain the value from the
motor supplier.
3. Use the X
2
default setting. The
frequency converter establishes
the setting on the basis of the
motor name plate data.
See Illustration 3.6.
1-35 Main Reactance (Xh)
Range: Function:
Size
related*
[ 1.0000 -
10000.0000
Ohm]
Set the main reactance of the motor
using one of these methods:
1. Run an AMA on a cold motor.
The frequency converter will
measure the value from the
motor.
2. Enter the X
h
value manually.
Obtain the value from the
motor supplier.
3. Use the X
h
default setting.
The frequency converter
establishes the setting on the
basis of the motor name
plate data.
1-36 Iron Loss Resistance (Rfe)
Range: Function:
Size
related*
[ 0 -
10000.000
Ohm]
Enter the equivalent iron loss
resistance (R
Fe
) value to compensate
for iron loss in the motor.
1-36 Iron Loss Resistance (Rfe)
Range: Function:
The R
Fe
value cannot be found by
performing an AMA.
The R
Fe
value is especially important
in torque control applications. If R
Fe
is unknown, leave 1-36 Iron Loss
Resistance (Rfe) on default setting.
1-37 d-axis Inductance (Ld)
Range: Function:
Size
related*
[ 0 -
1000.0
mH]
Enter the value of the d-axis inductance.
Obtain the value from the permanent
magnet motor data sheet.
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).
FC 302 only.
1-39 Motor Poles
Range: Function:
Size related* [2 - 100 ] Enter the number of motor poles.
Poles ~n

2 2700-2880 3250-3460
4 1350-1450 1625-1730
6 700-960 840-1153
Table 3.4
The table shows the number of poles for normal speed
ranges of various motor types. Define motors designed for
other frequencies separately. The motor pole value is
always an even number, because it refers to the total
number of poles, not pairs of poles. The frequency
converter creates the initial setting of 1-39 Motor Poles
based on 1-23 Motor Frequency and 1-25 Motor Nominal
Speed.
1-40 Back EMF at 1000 RPM
Range: Function:
Size
related*
[ 10. -
9000 V]
Set the nominal back EMF for the motor
when running at 1000 RPM. This
parameter is only active when
1-10 Motor Construction is set to [1] PM
motor (Permanent Magnet Motor).
FC 302 only.
