Use the X default setting. The
1
frequency converter establishes
the setting on the basis of the
motor name plate data.
Run an Auto Tune on a cold
motor. The frequency converter
will measure the value from the
motor.
Enter the X value manually.
2
Obtain the value from the motor
supplier.
Use the X default setting. The
2
frequency converter establishes
the setting on the basis of the
motor name plate data.
Run an Auto Tune on a cold
motor. The frequency
converter will measure the
value from the motor.
Enter the X value manually.
h
Obtain the value from the
motor supplier.
Use the X default setting.

The frequency converter
establishes the setting on
the basis of the motor name

P-36 Iron Loss Resistance (Rfe)
Range: Function:
10000.000 [0 - Enter the equivalent iron loss
Ohm 10000.000 resistance (R

The R
important in torque control
applications. If R
leave P-36 Iron Loss Resistance (Rfe)
on default setting.
P-37 d-axis Inductance (Ld)
Range: Function:
0 mH [0.000 - Enter the value of the d-axis
*
1000.000 mH] inductance. Obtain the value from the
permanent magnet motor data sheet.
The d-axis inductance cannot be found
by performing an Auto Tune.
P-46 Position Detection Gain
Range: Function:
100 % [20 - 200 %] Adjusts the amplitude of the test pulse
