NOTICE
When 1-10 Motor Construction is set to [1] PM, non-salient
SPM, the only option available is [2] Enable Reduced AMA.
Activate the AMA function by pressing [Hand On] after
selecting [1] or [2]. 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 can not 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.

TR150 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 1-30 Stator Resistance (Rs) to
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,
1-30 Stator Resistance (Rs) to 1-39 Motor Poles, will return
to default setting.
NOTICE
Full AMA should be run without filter only while
reduced AMA should be run with filter.

while the motor is running.
Set the stator resistance value. Enter the
value from a motor data sheet or
perform an AMA on a cold motor.
Function:
[ 0.0 - 999.9 Ohm] Set stator leakage reactance of
motor.
Function:
Set the main reactance of the motor using
one of these methods:
1. Run an AMA on a cold motor. The
frequency converter measures the
value from the motor.
2. Enter the X value manually. Obtain
h
the value from the motor supplier.
3. Use the X default setting. The
h
frequency converter establishes the
setting on the basis of the motor
name plate data.
Function:
[ 0 - Obtain the value from the permanent
1000 ] magnet motor data sheet. The d-axis
inductance cannot be found by
performing an AMA.
