1-29 Automatic Motor Adaptation (AMA)
Option: 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 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
frequency converter 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 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.
NOTICE
It is important to set motor parameters in parameter
group 1-2* Motor Data correctly, since these form part of
the AMA algorithm. An AMA must be performed to
achieve optimum dynamic motor performance. It may
take up to 10 min, depending on the power rating of the
motor.
NOTICE
Avoid generating external torque during AMA.
