Parameter Description
1-35 Main Reactance (Xh)
Range:
100.000 [1.0000 - 10000.0000 Ohm] Set the main reactance of the motor using one of these methods:
0 Ohm*
Note
This parameter cannot be adjusted while running.
1-36 Iron Loss Resistance (Rfe)
Range:
10000.0 [0 - 10000.000 Ohm]
00
Ohm*
Note
This parameter cannot be adjusted while the motor is running.
1-39 Motor Poles
Range:
4. N/A* [2 - 100 N/A]
62
Function:
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.
Function:
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
ting.
Function:
Enter the number of motor poles.
Poles ~n n @ 50 Hz
2 2700 - 2880
4 1350 - 1450
6 700 - 960
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
