If the motor starts oscillating at a certain speed, increase 1-14 Damping Gain.
Increase the value in small steps. Depending on the motor, a good value for this
parameter can be 10% or 100% higher than the default value. Starting torque can
be adjusted in 1-66 Min. Current at Low Speed. 100% provides nominal torque as
starting torque.
5.4.5 Automatic Energy Optimization (AEO)
Note: AEO is not relevant for permanent magnet motors.
Automatic Energy Optimization (AEO) is a procedure that minimizes voltage to the
motor, reducing energy consumption, heat, and noise.
To activate AEO, set parameter 1-03 Torque Characteristics to [2] Auto Energy
Optim. CT or [3] Auto Energy Optim. VT.
5.4.6 Automatic Motor Adaptation (AMA)
Note: AMA is not relevant for permanent magnet motors.
Automatic motor adaptation (AMA) is a procedure that optimizes compatibility
between the adjustable frequency drive and the motor.

Motor
The adjustable frequency drive builds a mathematical model of the motor for
regulating output motor current. The procedure also tests the input phase
balance of electrical power. It compares the motor characteristics with the data
entered in parameters 1-20 to 1-25.
The motor shaft does not turn and no harm is done to the motor while running
the AMA.
Some motors may be unable to run the complete version of the test. In that case,
select [2] Enable reduced AMA.
If an output filter is connected to the motor, select Enable reduced AMA.
Key
1-17 Voltage filter time const. to be increased by
factor 5 to 10
1-14 Damping Gain should be
reduced
1-66 Min. Current at Low Speed
should be reduced (<100%)
Keep calculated values
1-14 Damping Gain, 1-15 Low Speed Filter Time
Const. and 1-16 High Speed Filter Time Const. should
be increased
1-17 Voltage filter time const. should be increased
1-66 Min. Current at Low Speed should be increased
(>100% for a prolonged time can overheat the motor)
