1-10 Motor Construction
Option: Function:
NOTICE
This option is valid for FC 302 only.
This option is fully functional in
firmware version 7.31 and later.
Consult Danfoss before using this
option in a frequency converter with
an earlier firmware version.
1-11 Motor Model
Option: Function:
Automatically sets the factory values for the
selected motor. If the default value
Std.
Asynchron is used, determine settings
manually according to the selection
parameter 1-10 Motor Construction .
[1] Std.
Asynchron Default motor model when [0] Asynchron is
selected in parameter 1-10 Motor
Construction .
[2] Std. PM, non
salient Selectable when [1] PM, non-salient SPM is
selected in parameter 1-10 Motor
Construction .
[3] Std. PM
salient
[10] Danfoss OGD
LA10
Selectable when [1] PM, non-salient SPM is
selected in parameter 1-10 Motor
Construction . Only available for T4, T5 in 1.5–
3 kW. Settings are loaded automatically for
this specific motor.
[11] Danfoss OGD
V210
Selectable when [1] PM, non-salient SPM is
selected in parameter 1-10 Motor
Construction . Only available for T4, T5 in
0.75–3 kW. Settings are loaded automatically
for this specific motor.
1-14 Damping Gain
Range: Function:
140
%
*
[0 -
250 %] The damping gain stabilizes the PM machine to
run smoothly and with stability. The value of
damping gain controls the dynamic performance
of the PM machine. High damping gain gives
high dynamic performance and low damping
gain gives 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 becomes 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
1-15 Low Speed Filter Time Const.
Range: Function:
constant. However, if this value is too
short, the control becomes unstable.
1-16 High Speed Filter Time Const.
Range: Function:
Size related
*
[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 becomes unstable.
1-17 Voltage filter time const.
Range: Function:
Size
related
*
[0.001 - 2
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.
1-18 Min. Current at No Load
Range: Function:
0 %
*
[0 - 50 %] Adjust this parameter to achieve a smoother
motor operation.
3.2.6 1-2* Motor Data
This parameter group contains input data from the
nameplate on the connected motor.
NOTICE
Changing the value of these parameters affects the
setting of other parameters.
NOTICE

parameter 1-10 Motor Construction is set to [1] PM, non-
salient SPM , [2] PM, salient IPM , [5] Sync. Reluctance :
•
Parameter 1-20 Motor Power [kW] .
•
Parameter 1-21 Motor Power [HP] .
•
Parameter 1-22 Motor Voltage .
•
Parameter 1-23 Motor Frequency .
