Function:
The motor pole value is always an even
number, because it refers to the total pole
numbers, not pairs of poles.
Function:
[10 - 9000 V] Line-line RMS back EMF voltage at
1000 RPM.
Function:
[0 - This parameter corresponds to the
inductance saturation of Ld. Ideally, this
parameter has the same value as
parameter 1-37 d-axis Inductance (Ld). If
the motor supplier provides an induction
curve, enter the induction value at 200%
of the nominal value.
Function:
[0 - This parameter corresponds to the
inductance saturation of Lq. Ideally, this
parameter has the same value as
parameter 1-38 q-axis Inductance (Lq). If
the motor supplier provides an induction
curve, enter the induction value at 200%
of the nominal value.
Function:
Adjusts the amplitude of the test pulse
during position detection at start. Adjust
this parameter to improve the position
measurement.
Function:
This parameter specifies the saturation curve of
the d-inductance values. From 20–100% of this
parameter, the inductances are linearly
approximated due to parameter 1-37 d-axis
Inductance (Ld), parameter 1-38 q-axis Inductance
(Lq), parameter 1-44 d-axis Inductance Sat.
(LdSat), and parameter 1-45 q-axis Inductance
Sat. (LqSat). Below and above they are specified
by the corresponding parameters. Parameters
are related to the motor nameplate load
compensations, the application load type, and
the electronic brake function for quick stop/
hold of the motor.

Function:
[ 20 - This parameter specifies the saturation curve of

Function:
[0 - 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
magnetizing current. If the setting is too low, the
torque on the motor shaft may be reduced.
