Table 3.5 Recommendations for Various Applications
If the motor starts oscillating at a certain speed, increase
parameter 1-14 Damping Gain. Increase the damping gain
value in small steps. Depending on the motor, this
parameter can be set to 10–100% higher than the default
value.

Settings
Increase parameter 1-14 Damping
Gain, parameter 1-15 Low Speed Filter
Time Const., and parameter 1-16 High
Speed Filter Time Const.
Increase parameter 1-17 Voltage filter
time const.
Increase parameter 1-66 Min. Current
at Low Speed to adjust the starting
torque. 100% current provides
nominal torque as starting torque.
This parameter is independent of
parameter 30-20 High Starting Torque
Time [s] and parameter 30-21 High
Starting Torque Current [%]). Working
at a current level higher than 100%
for a prolonged time can cause the
motor to overheat.
Increase parameter 14-41 AEO
Minimum Magnetisation for highly
dynamic applications. Adjusting
parameter 14-41 AEO Minimum
Magnetisation ensures a good
balance between energy efficiency
and dynamics. Adjust
parameter 14-42 Minimum AEO
Frequency to specify the minimum
frequency at which the frequency
converter should use minimum
magnetization.
Avoid short ramp-down times.
Function:
Select the motor design type.
NOTICE
FC 301 allows only selection of
asynchronous motors.
Use for ASM/IM motors.
Use for SPM motors, surface
mounted magnet.
PM motors are divided into 2
groups, with either surface-
mounted (SPM)/non-salient
magnets or interior-mounted (IPM)/
salient magnets.

[2] PM, salient Use for IPM motors, interior-
IPM mounted magnet.
PM motors are divided into 2
groups, with either surface-
mounted (SPM)/non-salient
magnets or interior-mounted (IPM)/
salient magnets.

[5] SynRM Use for SynRM, synchronous
reluctance motors.
[6] PMaSynRM Use for PMaSynRM, Permanent
Magnet assisted synchronous
reluctance motors.
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 Selectable when [1] PM, non-salient
salient SPM is selected in
parameter 1-10 Motor Construction.
[3] Std. PM salient
[10] Danfoss OGD Selectable when [1] PM, non-salient
LA10 SPM is selected in
parameter 1-10 Motor Construction.
Only available for T4, T5 in 1.5–
3 kW. Settings are loaded automat-
ically for this specific motor.
[11] Danfoss OGD Selectable when [1] PM, non-salient
V210 SPM is selected in
parameter 1-10 Motor Construction.
Only available for T4, T5 in 0.75–
3 kW. Settings are loaded automat-
ically for this specific motor.
