152 Stator Leakage Reactance
(STATOR LEAKAGE)
Value:
Ohm
✭
Depends on unit
Function:
Set the stator leakage reactance of the motor.
Description of choice:
X
1
can be set as follows:
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
1
, selected by the
frequency converter itself on the basis of the
motor nameplate data, is used.
153 Rotor Leakage Reactance
(ROTOR LEAKAGE)
Value:
Ohm
✭
Depends on unit
Function:
Set the rotor leakage reactance of the motor.
Description of choice:
X
2
can be set as follows:
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
2
, selected by the
frequency converter itself on the basis of the
motor nameplate data, is used.
154 Main Reactance
(MAIN REACTANCE)
Value:
Ohm ✭
Depends on unit
Function:
Set the main reactance of the motor.
Description of choice:
X
h
can be set as follows:
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
h
, selected by the
frequency converter itself on the basis of the
motor nameplate data, is used.
156 Pole Number (POLE NUMBER)
Value:
Depends on motor type
Value 2 - 100 poles ✭
4-pole motor
Function:
Set the pole number of the motor
Description of choice:
Poles ~ n
n
@ 50 Hz ~ n
n
@ 60Hz
2 2700 - 2880 3250 - 3460
4 1350 - 1450 1625 - 1730
6 700 - 960 840 - 1153
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
✭
10.000
Function:
Set the equivalents of the R
Fe
to compensate
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:
R
Fe
< P
0
