Parameter Descriptions
Application Settings
Low inertia applications Keep calculated values
High inertia applications parameter 1-66 Min. Current at Low
Speed
Increase speed to a value between
default and maximum depending on
application.
Set ramp times matching the
application. Too fast ramp up causes
an overcurrent/overtorque. Too fast
ramp down causes an overvoltage
trip.
High load at low speed parameter 1-66 Min. Current at Low
Speed
Increase speed to a value between
default and maximum depending on
application.
Table 3.5 Recommendations for FLUX Applications
Adjust starting torque in parameter 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 valid for FC 302 and
FCD 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
parameter 1-10 Motor Construction.
[1] Std. Default motor model when [0]* Asynchron is
Asynchron selected in parameter 1-10 Motor Construction.
Enter motor parameter manually.
[2] Std. PM, non Selectable when [1] PM, non salient SPM is
salient selected in parameter 1-10 Motor Construction.
Enter motor parameter manually.
[10] Danfoss Selectable when [1] PM, non-salient SPM is
OGD LA10 selected in parameter 1-10 Motor Construction.
Only available for T4, T5 in 1.5-3 kW. Settings

1-11 Motor Model
Option:
[11] Danfoss
OGD V206
OGD Auto-Detection and Model Change Function
The function is activated when one of the following
options is selected: either [10] Danfoss OGD LA10 or [11]
Danfoss OGD V206 in parameter 1-11 Motor Model.
The frequency converter checks if the correct OGD model
is selected. If a wrong OGD model is selected, the
frequency converter performs the following actions:
•
•
•
•
The model check takes place every time the frequency
converter gets a start signal from the LCP, a digital input
or a fieldbus.

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.

Function:
[0 - The damping gain stabilises the PM machine to
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.
