152 Stator Leakage Reactance

(STATOR LEAKAGE)
Value:
Ohm
Function:
Set the stator leakage reactance of the motor.
Description of choice:
X can be set as follows:
1
1. Automatic Motor Adaptation, where the
frequency converter measures on the motor
to determine the value.
2. The motor supplier states the value.
3. The factory setting of X
frequency converter itself on the basis of the
motor nameplate data, is used.

153 Rotor Leakage Reactance

(ROTOR LEAKAGE)
Value:
Ohm
Function:
Set the rotor leakage reactance of the motor.
Description of choice:
X can be set as follows:
2
1. Automatic Motor Adaptation, where the
frequency converter measures on the motor
to determine the value.
2. The motor supplier states the value.
3. The factory setting of X
frequency converter itself on the basis of the
motor nameplate data, is used.
154 Main Reactance
(MAIN REACTANCE)
Value:
Ohm
Function:
Set the main reactance of the motor.
Description of choice:
X can be set as follows:
h
1. Automatic Motor Adaptation, where the
frequency converter measures on the motor
to determine the value.
2. The motor supplier states the value.

156 Pole Number (POLE NUMBER)
Value:
Depends on motor type
Value 2 - 100 poles
Function:
Set the pole number of the motor
Description of choice:
Poles ~ n @ 50 Hz
n
2 2700 - 2880
4 1350 - 1450
6 700 - 960
The above table shows the normal speed range
for various motor types. Motors designed for other
frequencies must be defined separately.

158 Iron loss Resistance

(IRONLOSS RES.)
Value:
1 -10.000
Function:
Set the equivalents of the R
for iron losses in the motor.
Description of choice:
The function is switched off when the value
10.000 is chosen.
The Iron loss resistance most be less than:
2
R < P / I
Fe 0 0
