3.3.2 1-1* Special Settings
NOTE
This parameter group cannot be adjusted while the motor
is running.
1-10 Motor Construction
Option:
Function:
Select the motor construction type.
[0]
*
Asynchron
For asynchronous motors.
[1]
PM, non salient
SPM
For permanent magnet (PM) motors.
Note that PM motors are divided into
two groups, with either surface mounted
(non salient) or interior (salient) magnets.
Motor construction can either be asynchronous or
permanent magnet (PM) motor.
1-11 Motor Model
Automatically sets the manufacturer’s values for the selected
motor. If the default value [1] is used, settings must to be
determined manually, according to the choice in
This parameter is FC302 only.

Std. PM, non salient
[10]
Danfoss OGD LA10
Settings are loaded
automatically for this
specific motor.
NOTE
This parameter is FC302 only.
1-14 Damping Gain
Range:
Function:
140
%
*
[0 -
250 %]
The damping gain will stabilize the PM machine
in order to run the PM machine smooth and
stable. The value of Damping gain will control
the dynamic performance of the PM machine.
High damping gain will give high dynamic
performance and low damping gain will give low
dynamic performance. The dynamic performance
is related to the machine data and load type. If
the damping gain is too high or low the control
will become unstable.
1-15 Low Speed Filter Time Const.
Range:
Function:
Size related
*
[0.01 -
20.00 s]
This time constant is used below
10% rated speed. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control gets
unstable.
1-16 High Speed Filter Time Const.
Range:
Function:
Size related
*
[0.01 -
20.00 s]
This time constant is used above
10% rated speed. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control gets
unstable.
1-17 Voltage filter time const.
Range:
Function:
Size related
*
[0.001 -
1.000 s]
Reduces the influence of high
frequency ripple and system
resonance in the calculation of
supply voltage. Without this filter, the
ripples in the currents can distort the
calculated voltage and affect the
stability of the system.
3.3.3 1-2* Motor Data
Parameter group 1-2* comprises input data from the
nameplate on the connected motor.
NOTE
Changing the value of these parameters affects the setting
of other parameters.
1-20 Motor Power [kW]
Range:
Function:
Size
related
*
[ 0.09 -
3000.00
kW]
Enter the nominal motor power in kW
according to the motor nameplate data.
The default value corresponds to the
nominal rated output of the unit.
This parameter cannot be adjusted
while the motor is running. This
parameter is visible in LCP if
is
[0] International.
NOTE
Four sizes down, one size up from
nominal unit rating.
