1-35 Main Reactance (Xh)
Range: Function:
Application [Application Set the main reactance of the motor
dependent dependant] using one of these methods:
*
1-36 Iron Loss Resistance (Rfe)
Range:
Application [Application
dependent dependant]
*
1-37 d-axis Inductance (Ld)
Range:
Application [Application Enter the value of the d-axis
dependent dependant] inductance. Obtain the value from
*
the permanent magnet motor data
sheet.
This parameter is only active when
1-10 Motor Construction has the
value PM, non-salient SPM [1]
(Permanent Magnet Motor).
For a selection with one decimal,
use this parameter. For a selection
with three decimals, use 30-80 d-
axis Inductance (Ld).
FC 302 only.
1. Run an AMA on a cold
motor. The frequency
converter will measure the
value from the motor.
2. Enter the X value
h
manually. Obtain the value
from the motor supplier.
3. Use the X default setting.
h
The frequency converter
establishes the setting on
the basis of the motor
name plate data.
Function:
Enter the equivalent iron loss
resistance (R ) value to
Fe
compensate for iron loss in the
motor.
The R value cannot be found by
Fe
performing an AMA.
The R value is especially
Fe
important in torque control
applications. If R is unknown,
Fe
leave 1-36 Iron Loss Resistance
(Rfe) on default setting.
