Parameters
1-46 Position Detection Gain
Range: Function:
100 % [ 20 - Use this parameter to adjust the height of
*
200 %] the test pulse during position detection at
start. This parameter is valid from software
version 2.80.
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 - This parameter specifies the saturation curve of
200 %] the q-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.
3.2.7 1-5* Load Indep. Setting
Parameters for load-independent motor settings.
1-50 Motor Magnetisation at Zero Speed
Range: Function:
100 [0 - Use this parameter along with parameter 1-52 Min
% 300 % 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.

Function:
[0.1 - 10.0 Set the required frequency for normal
magnetizing current.
Use this parameter along with
parameter 1-50 Motor Magnetisation at Zero
Speed. See Illustration 3.2.
Function:
[0 - 999 Enter voltage at each frequency point
*
V] to form a U/f characteristic matching
the motor. Frequency points are
defined in parameter 1-56 U/f Charac-
teristic - F.
Function:
[0 - Enter frequency points to form a U/f charac-
400.0 teristic matching the motor. Voltage at each
Hz] point is defined in parameter 1-55 U/f Charac-
teristic - U.
Make a U/f characteristic based on 6 definable
voltages and frequencies, see Illustration 3.3.
Simplify U/f characteristics by merging 2 or
more points (voltages and frequencies). Set
the points at equal values.
