Danfoss VLT HVAC Basic Drive FC 101 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 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.
