Parameter Description
1-34 Rotor Leakage Reactance (X2)
Range: Function:
Size [ 0.0400 - Set the rotor leakage reactance of the
related 400.0000 motor using one of these methods:
*
Ohm]
1.
2.
3.
See Figure 3.4.
NOTICE!
1-34 Rotor Leakage Reactance (X2) will not have effect when
1-10 Motor Construction = [1] PM, non-salient SPM.

Range: Function:
Size [ 1.0000 - Set the main reactance of the motor
related 10000.0000 using one of these methods:
*
Ohm]
1.
2.
3.
NOTICE!
1-35 Main Reactance (Xh) will not have effect when
1-10 Motor Construction = [1] PM, non-salient SPM.
NOTICE!
This parameter cannot be adjusted while running.

1-36 Iron Loss Resistance (Rfe)
Range: Function:
Size [ 0 - Enter the equivalent iron loss
related 10000.000 resistance (R
*
Ohm] for iron losses in the motor.
The R
performing an AMA.
The R
in torque control applications. If R
is unknown, leave 1-36 Iron Loss
Resistance (Rfe) on default setting.
NOTICE!
This parameter cannot be adjusted while the motor is
running.
NOTICE!
This parameter is not available from the LCP.
1-37 d-axis Inductance (Ld)
Range:
Size related [ 0.000 - 0.000
*
mH]
NOTICE!
This parameter is only active when 1-10 Motor Construction
has the value PM, non-salient SPM [1] (Permanent Magnet
Motor).
Stator resistance and d-axis Inductance values are
normally, for asynchronous motors, described in technical
specifications as between line and common (starpoint). For
permanent magnet motors, they are typically described in
technical specifications as between Line-Line. PM motors
are typically built for star connection.
