*
[ 0.0400 -
400.0000
Ohm]
NOTICE
This parameter is only relevant
for asynchronous motors.
Set the rotor leakage reactance of
the motor using 1 of these
methods:
•
Run an AMA on a cold
motor. The frequency
converter measures the
value from the motor.
•
Enter the X
2
value
manually. Obtain the value
from the motor supplier.
•
Use the X
2
default setting.
The frequency converter
establishes the setting
based on the motor
nameplate data.
See

NOTICE
The parameter value is
updated after each torque
calibration if option
[3] 1st
start with store
or option
[4]
Every start with store
is
selected in
parameter 1-47 Torque

Ohm]
Set the main reactance of the
motor using 1 of these methods:
1.
Run an AMA on a cold
motor. The frequency
converter measures the
value from the motor.
2.
Enter the X
h
value
manually. Obtain the value
from the motor supplier.

*
[ 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 AMA.
The R
Fe
value is especially
important in torque control
applications. If R
Fe
is unknown,
leave
on default setting.
1-37 d-axis Inductance (Ld)
Range:
Function:
Size

*
[0.000 -
1000.000 mH]
Enter line-to-common direct axis
inductance of the PM motor. Obtain
the value from the permanent
magnet motor datasheet.
If only line-line data is available,
divide the line-line value by 2 to
achieve the line-common (star
point) value. Alternatively, measure
the value with an inductance meter.
This also takes the inductance of
the cable into account. Divide the
measured value by 2 and enter the
result.
This parameter is only active when
parameter 1-10 Motor Construction
is
set to
[1] PM, non-salient SPM
(Permanent Magnet Motor).
For a selection with 1 decimal, use
this parameter.
NOTICE
The parameter value is
updated after each torque
calibration if option
[3] 1st
