1-29 Automatic Motor Adaptation (AMA)
Option: 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 (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 reads: "Press [OK]
to finish AMA". After pressing [OK] the
adjustable frequency drive is ready for
operation.

[1] Enable
complete
AMA
Performs AMA of the stator resistance R
S
, the
rotor resistance R
r
, the stator leakage reactance
X
1
, the rotor leakage reactance X
2
and the
main reactance X
h
.
FC 301: The complete AMA does not include
X
h
measurement for FC 301. Instead, the X
h
value is determined from the motor database.
1-35 Main Reactance (Xh) may be adjusted to
obtain optimal start performance.
[2] Enable
reduced
AMA
Performs a reduced AMA of the stator
resistance R
s
in the system only. Select this
option if an LC filter is used between the drive
and the motor.
Note:
•
For the best adaptation of the adjustable
frequency drive, run the AMA on a cold motor.
•
AMA cannot be performed while the motor is
running.
•
AMA cannot be performed on permanent magnet
motors.
