1-31 Rotor Resistance (Rr)
Range: Function:
converter will measure the
value from the motor. All
compensations are reset to
100%.
2. Enter the R
r
value manually.
Obtain the value from the
motor supplier.
3. Use the R
r
default setting.
The frequency converter
establishes the setting on
the basis of the motor
nameplate data.
1-33 Stator Leakage Reactance (X1)
Range: Function:
Application
dependent
*
[Application
dependant] Set the stator leakage reactance of
the motor using one of these
methods:
1. Run an AMA on a cold
motor. The frequency
converter will measure the
value from the motor.
2. Enter the X
1
value
manually. Obtain the value
from the motor supplier.
3. Use the X
1
default setting.
The frequency converter
establishes the setting on
the basis of the motor
name plate data.
1-34 Rotor Leakage Reactance (X2)
Range: Function:
Application
dependent
*
[Application
dependant] Set the rotor leakage reactance of
the motor using one of these
methods:
1. Run an AMA on a cold
motor. The frequency
converter will measure the
value from the motor.
2. Enter the X
2
value
manually. Obtain the value
from the motor supplier.
3. Use the X
2
default setting.
The frequency converter
establishes the setting on
the basis of the motor
name plate data.
1-35 Main Reactance (Xh)
Range: Function:
Application
dependent
*
[Application
dependant] Set the main reactance of the motor
using one of these methods:
1. Run an AMA 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.
1-36 Iron Loss Resistance (Rfe)
Range: Function:
Application
dependent
*
[Application
dependant] 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 AMA.
The R
Fe
value is especially
important in torque control
applications. If R
Fe
is unknown,
leave 1-36 Iron Loss Resistance
(Rfe) on default setting.
1-37 d-axis Inductance (Ld)
Range: Function:
Application
dependent
*
[Application
dependant] Enter the value of the d-axis
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.
