P-35 Main Reactance (Xh)
Range: Function:
100.0000
Ohm*
[1.0000 - 10000.0000 Ohm] Set the main reactance of the motor using one of these methods:
1. Run an Auto Tune 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 supplier.
3. Use the X
h
default setting. The frequency converter establishes the setting on the basis of the
motor name plate data.
P-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 loss in the motor.
The R
Fe
value cannot be found by performing an Auto Tune.
The R
Fe
value is especially important in torque control applications. If R
Fe
is unknown, leave par. P-36 Iron
Loss Resistance (Rfe) on default setting.
P-37 d-axis Inductance (Ld)
Range: Function:
0 mH* [0 - 0.000 mH] Enter the value of the d-axis inductance. Obtain the value from the permanent magnet motor data sheet.
The d-axis inductance cannot be found by performing an Auto Tune.
