1-36 Iron Loss Resistance (Rfe)
Range: Function:
10000.000
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.

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

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 adjustable frequency drive creates the
initial setting of par.1-39
Motor Poles
based on par.1-23
Motor Frequency
and par.1-25
