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

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. Alterna-
tively, 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) or
[5] Sync. Reluctance
.
For a selection with 1 decimal, use this
parameter. For a selection with 3 decimals,
use
parameter 30-80 d-axis Inductance (Ld)
FC 302 only.
