1-43 Motor Cable Length Feet
Range: Function:
164 ft
*
[0 - 328 ft] Set the motor cable length. The length unit
is foot.
1-44 d-axis Inductance Sat. (LdSat)
Range: Function:
Size
related [ 0 -
1000
mH] This parameter is active only when
parameter 1-10 Motor Construction
is set to
[3]
PM, salient IPM, Sat
.
This parameter corresponds to the saturation
inductance of d-axis. The default value is the
value set in
parameter 1-37 d-axis Inductance
(Ld)
. Do not change the default value in most
cases. If the motor supplier provides the
saturation curve, enter the d-axis inductance
value, which is 100% of the nominal current.

*
[ 0 -
1000
mH] This parameter is active only when
parameter 1-10 Motor Construction is set to
[3] PM, salient IPM, Sat .
This parameter corresponds to the q-axis
saturation inductance. The default value is
the value set in
parameter 1-38 q-axis
Inductance (Lq) . Do not change the default
value in most cases. If the motor supplier
provides the saturation curve, enter the q-
axis inductance value, which is 100% of the
nominal current.
1-46 Position Detection Gain
Range: Function:
100 %
*
[ 20 -
200 %] Adjusts the amplitude of the test pulse
during position detection at start. Adjust
this parameter to improve the position
measurement.
1-48 Current at Min Inductance for d-axis
Range: Function:
100 % [ 20 - 200 %] Use this parameter to set the inductance
saturation point.
1-49 Current at Min Inductance for q-axis
Range: Function:
100 % [ 20 -
200 %]
This parameter specifies the saturation curve of
the q-inductance values. From 20–100% of this
parameter, the inductance is linearly
approximated due to
parameter 1-38 q-axis
Inductance (Lq) and parameter 1-45 q-axis
Inductance Sat. (LqSat) . These parameters are
related to the motor nameplate load compen-
sations, the application load type, and the
1-49 Current at Min Inductance for q-axis
Range: Function:
electronic brake function for quick stop/hold of
the motor.
4.2.6 1-5* Load Indep. Setting
Parameters for load-independent motor settings.
1-50 Motor Magnetisation at Zero Speed
Range: Function:

%
*
[0 -
300 %
] Use this parameter along with parameter 1-52 Min
Speed Normal Magnetising [Hz] to obtain a
different thermal load on the motor when running
at low speed.
Enter a value that is a percentage of the rated
magnetising current. If the setting is too low, the
torque on the motor shaft may be reduced.
