Parameter Descriptions
1-10 Motor Construction
Option: Function:
PM motors are divided into two groups,
with either surface mounted (non salient)
or interior (salient) magnets.
[3] SynRM
1-11 Motor Model
Automatically sets the manufacturer's values for the selected
motor. If the default value [1] is used, settings must be
determined manually, according to the choice in 1-10 Motor
Construction.
This parameter is FC 302 only.
Option: Function:
[1] Std. Asynchron Default motor model when [0]*
Asynchron is selected in 1-10 Motor
Construction. Enter motor parameter
manually.
[2] Std. PM, non salient Selectable when [1] PM, non salient
SPM is selected in 1-10 Motor
Construction. Enter motor parameter
manually.
[10] Danfoss OGD LA10 Selectable when [1] PM, non salient
SPM is selected in 1-10 Motor
Construction. Only available for T4, T5
in 1.5-3 kW. Settings are loaded
automatically for this specific motor.
See Table 3.4 for details.
NOTE
This parameter is FC 302 only.
1-14 Damping Gain
Range: Function:
140 [0 - The damping gain will stabilize the PM machine
% 250 %] 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 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.

3.3.4 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.
NOTE
1-20 Motor Power [kW], 1-21 Motor Power [HP], 1-22 Motor
Voltage and 1-23 Motor Frequency will not have effect
when 1-10 Motor Construction = [1] PM, non salient SPM.

MG33MG02 - VLT is a registered Danfoss trademark
Function:
[0.01 - 20 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.
Function:
[0.001 - 1 Reduces the influence of high
*
s] 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.

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.
