1-35 Main Reactance (Xh)
Range: Function:
100.000
0 Ohm*
[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 sup-
plier.
3. Use the X
h
default setting. The frequency converter establishes the
setting on the basis of the motor name plate data.
Note
This parameter cannot be adjusted while running.
1-36 Iron Loss Resistance (Rfe)
Range: Function:
10000.0
00
Ohm*
[0 - 10000.000 Ohm] Enter the equivalent iron loss resistance (R
Fe
) value to compensate for
iron losses in the motor.
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 par.1-36
Iron Loss Resistance (Rfe) on default set-
ting.
Note
This parameter cannot be adjusted while the motor is running.
1-39 Motor Poles
Range: Function:
4. N/A* [2 - 100 N/A] Enter the number of motor poles.
Poles ~n
n
@ 50 Hz ~n
n
@60 Hz
2 2700 - 2880 3250 - 3460
4 1350 - 1450 1625 - 1730
6 700 - 960 840 - 1153
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 par.1-39
Motor Poles based on par.1-23 Motor Fre-
quency
Motor Frequency
and par.1-25 Motor Nominal Speed
Motor Nom-
inal Speed
.
This parameter cannot be adjusted while the motor is running.
