NOTICE
When parameter 1-10 Motor Construction is set to options
that enable permanent motor mode, the only option
available is [1] Enable Complete AMA.
Activate the AMA function by pressing [Hand On] after
selecting [1] Enable Complete AMA or [2] Enable Reduced
AMA. After a normal sequence, the display reads: Press [OK]
to finish AMA. After pressing [OK], the frequency converter
is ready for operation.

Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor parameters while the motor is
stationary.
No function
When parameter 1-10 Motor Construction is set
to [0] Asynchron, perform AMA of
parameter 1-30 Stator Resistance (Rs),
parameter 1-33 Stator Leakage Reactance (X1),
and parameter 1-35 Main Reactance (Xh).
When parameter 1-10 Motor Construction is set
to options that enable permanent motors,
perform AMA of parameter 1-30 Stator
Resistance (Rs), and parameter 1-37 d-axis
Inductance (Ld).
NOTICE
Terminal 27 Digital Input
(parameter 5-12 Terminal 27 Digital Input)
has coast inverse as the default setting.
This means that AMA cannot be
performed if there is no 24 V to terminal
27.
Performs a reduced AMA of the stator
resistance R in the system only. Select this
s
option if an LC filter is used between the
frequency converter and the motor.

NOTICE
•
For the best adaptation of the frequency
converter, run AMA on a cold motor.
•
AMA cannot be performed while the motor is
running.
•
AMA cannot be performed on a motor with a
bigger power rating than the frequency
converter, for example, when a 5.5 kW (7.4 hp)
motor is connected to a 4 kW (5.4 hp)
frequency converter.
NOTICE
Avoid generating external torque during AMA.
NOTICE
If one of the settings in parameter group 1-2* Motor Data
is changed, the advanced motor parameters,
parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles, return to default setting.
NOTICE
Perform a full AMA without filter only, while reduced
AMA should be run with a filter.
3.2.5 1-3* Motor Data II
This parameter group comprises input data from the
nameplate on the connected motor.
NOTICE
These parameters cannot be adjusted while the motor is
running.
