1-46 Position Detection Gain
Range: Function:
100 % * [ 20 -
200 %]
Use this parameter to adjust the height of
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 -
200 %]
This parameter species the saturation curve of
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
specied
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 -
300 %
]
Use this parameter along with parameter 1-52 Min
Speed Normal Magnetising [Hz] to obtain a
dierent
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.

1-52 Min Speed Normal Magnetising [Hz]
Range: Function:
1 Hz * [0.1 - 10.0
Hz]
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.
1-55 U/f Characteristic - U
Array[6]
Range: Function:
Size related * [0 - 999
V]
Enter voltage at each frequency point
to form a U/f characteristic matching
the motor. Frequency points are
dened in parameter 1-56 U/f Charac-
teristic - F.

[0 -
400.0
Hz]
Enter frequency points to form a U/f charac-
teristic matching the motor. Voltage at each
point is dened in parameter 1-55 U/f Charac-
teristic - U.
Make a U/f characteristic based on 6 denable
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.

Parameters for adjusting the load-dependent motor
settings.

*
[-400 -

Enter the % value for slip compensation
to compensate for tolerances in the
value of n
M,N
. Slip compensation is
calculated automatically, which is based
on the nominal motor speed n
M,N
.
