NOTICE
When 1-10 Motor Construction is set to [1] PM, non-salient
SPM, 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.
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, e.g. when a 5.5 kW motor is
connected to a 4 kW frequency converter.
NOTICE
Avoid generating external torque during AMA.

Programming Guide
Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.
The AMA function optimises dynamic motor
performance by automatically optimising the
advanced motor parameter 1-30 Stator
Resistance (Rs) to parameter 1-35 Main
Reactance (Xh) while the motor is stationary.
No function
Performs AMA of the stator resistance R
stator leakage reactance X and the main
1
reactance X .
h
NOTICE
Terminal 27 Digital Input (5-12 Terminal
27 Digital Input) has coast inverse as
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
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
Full AMA should be run without filter only, while
reduced AMA should be run with filter.

4.2.4 1-3* Adv. Motor Data I

Set parameters for advanced motor data. The motor data
, the
S
in parameters 1-30 to 1-39 must match the motor for
optimal performance. If the motor data is not known,
running an AMA is recommended.

Set the stator resistance value. Enter
the value from a motor data sheet or
perform an AMA on a cold motor.
Function:
Set rotor resistance of
motor.
Function:
motor.
Function:
Set the main reactance of the motor using
one of these methods:
•
Run an AMA on a cold motor. The
frequency converter measures the
value from the motor.
•
Enter the X value manually.
h
Obtain the value from the motor
supplier.
•
Use the X default setting. The
h
frequency converter establishes the
setting on the basis of the motor
name plate data.
