FC101 Programming Guide
1-35 Main Reactance (Xh)
Range: Function:
measures the value from the
motor.
•
Enter the X
h
value manually.
Obtain the value from the motor
supplier.
•
Use the X
h
default setting. The
frequency converter establishes
the setting based on the motor
nameplate data.
1-37 d-axis Inductance (Ld)
Range: Function:
Size related* [ 0 - 65535 mH] Obtain the value from the
permanent magnet motor
datasheet.
1-38 q-axis Inductance (Lq)
Range: Function:
Size
related*
[ 0.000 -
65535 mH]
Set the value of the q-axis
inductance. Obtain the value from
the permanent magnet motor
datasheet. The value cannot be
changed when the motor is running.
1-39 Motor Poles
Range: Function:
Size
related*
[2 -
100 ]
Enter the number of motor poles. The
motor pole value is always an even
number, because it refers to the total
pole number, not pairs of poles.
3.2.6 1-4* Motor Data III
This parameter group comprises input data from the
nameplate on the connected motor.
NOTICE
These parameters cannot be adjusted while the motor is
running.
1-40 Back EMF at 1000 RPM
Range: Function:
Size related* [1 - 9000 V] Line-line RMS back EMF voltage at
1000 RPM.
1-42 Motor Cable Length
Range: Function:
50 m* [0 - 100 m] Set the motor cable length during commis-
sioning.
1-43 Motor Cable Length Feet
Range: Function:
164 ft* [0 - 328 ft] Set the motor cable length during commis-
sioning.
1-44 d-axis Inductance Sat. (LdSat)
Range: Function:
Size
related*
[ 0 -
65535
mH]
This parameter corresponds to the
inductance saturation of Ld. Ideally, this
parameter has the same value as
parameter 1-37 d-axis Inductance (Ld).
However, if the motor supplier provides
an induction curve, enter the induction
value here, which is 200% of the
nominal current.
1-45 q-axis Inductance Sat. (LqSat)
Range: Function:
Size
related*
[ 0 -
65535
mH]
This parameter corresponds to the
inductance saturation of Lq. Ideally, this
parameter has the same value as
parameter 1-38 q-axis Inductance (Lq).
However, if the motor supplier provides
an induction curve, enter the induction
value here, which is 200% of the
nominal current.
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 species 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 specied
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.
