Function:
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor parameters (parameters 1-30
to 1-35) at motor standstill.
Activate the AMA function by pressing [Hand
on] after selecting [1] or [2]. See also the
section Automatic Motor Adaptation. After a
normal sequence, the display will read: "Press
[OK] to finish AMA". After pressing the [OK]
key the frequency converter is ready for
operation.
This parameter cannot be adjusted while the
motor is running.
Performs AMA of the stator resistance R
rotor resistance R , the stator leakage
r
reactance X , the rotor leakage reactance X
1
and the main reactance X
FC 301: The complete AMA does not include
X measurement for FC 301. Instead, the X
h
value is determined from the motor database.
Par. 1-35 may be adjusted to obtain optimal
start performance.
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 drive
and the motor.
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 permanent magnet
motors.
