Parameter Descriptions
Adjust starting torque in 1-66 Min. Current at Low Speed.
100% provides nominal torque as starting torque.
1-10 Motor Construction
Option: Function:
Select the motor design type.
[0] Asynchron For asynchronous motors.
*
[1] PM, non salient For salient or non-salient PM motors.
SPM PM motors are divided into 2 groups, with
either surface-mounted (non-salient) or
interior (salient) magnets.
[3] SynRM
1-11 Motor Model
Option: Function:
NOTICE
This parameter is FC 302 only.
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.
[1] Std. Default motor model when [0]* Asynchron is
Asynchron selected in 1-10 Motor Construction. Enter
motor parameter manually.
[2] Std. PM, non Selectable when [1] PM, non salient SPM is
salient selected in 1-10 Motor Construction. Enter
motor parameter manually.
[10] Danfoss OGD Selectable when [1] PM, non salient SPM is
LA10 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.

1-14 Damping Gain
Range: Function:
140 [0 - The damping gain stabilises the PM machine to
% 250 run the PM machine smooth and stable. 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.
