Table 3.6 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 between 10% and 100% higher
than the default value.

Settings
Increase 1-17 Voltage filter time const.
by factor 5 to 10.
Reduce 1-14 Damping Gain.
Reduce 1-66 Min. Current at Low
Speed (<100%).
Keep the default values.
Increase 1-14 Damping Gain,
parameter 1-15 Low Speed Filter Time
Const., and parameter 1-16 High
Speed Filter Time Const.
Increase 1-17 Voltage filter time const.
Increase 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 14-41 AEO Minimum
Magnetisation for highly dynamic
applications. Adjusting 14-41 AEO
Minimum Magnetisation ensures a
good balance between energy
efficiency and dynamics. Adjust
14-42 Minimum AEO Frequency to
specify the minimum frequency at
which the frequency converter
should use minimum magnetisation.
Function:
Select the motor design type.
Use for asynchronous motors.
Use for salient or non-salient PM motors.
PM motors are divided into 2 groups, with
either surface-mounted (SPM) / non-salient
magnets or interior mounted (IPM) / salient
magnets. This option is valid for FC 302 only.
Use for salient or non-salient PM motors.

Use for synchronous reluctance motors. This
option is valid for FC 302 only.
CAUTION
This option has the following firmware
version limitations:
•
Version 7.26 and earlier - do
not use this option. There is a
risk of damage to the frequency
converter.
•
Version 7.27 - use this option
only when flying start is
enabled in
parameter 1-73 Flying Start.
