1-29 Automatic Motor Adaptation (AMA)
Option: Function:
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor parameters (par. 1-30 to par.
1-35) at motor standstill.
Activate the AMA function by pressing [Hand
on] after selecting [1] Enable complete AMA or
[2] Enable reduced AMA. See also the section
Automatic Motor Adaptation. After a normal
sequence, the display will read: "Press [OK] to
finish AMA". After pressing [OK], the frequency
converter is ready for operation.
1-29 Automatic Motor Adaptation (AMA)
Option: Function:
This parameter cannot be adjusted while the
motor is running.
[0] * OFF
[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
frequency converter 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.
It is important to set motor parameter group 1-2*
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.
Avoid generating external torque during AMA.
If one of the settings in parameter group 1-2* is changed,
par. 1-30 to par. 1-39, the advanced motor parameters, will
return to default setting.
