P-37 d-axis Inductance (Ld)
Range:
0 mH* [0 - 0.000 mH]
Function:
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 value manually. Obtain the value from the motor supplier.
h
3. Use the X 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
The R value cannot be found by performing an Auto Tune.
