1-29 Automatic Motor Adaptation (AMA)

VLT
Operating Instructions High Power
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.

Note:
•
[16]
For the best adaptation of the frequency
[17]
converter, run AMA on a cold motor.
[18]
•
AMA cannot be performed while the motor is
[19]
running.
[20]
•
AMA cannot be performed on permanent magnet
[21]
motors.
[22]
[23]
It is important to set motor parameter group 1-2*
[24]
correctly, since these form part of the AMA algorithm. An
[28]
AMA must be performed to achieve optimum dynamic
[29]
motor performance. It may take up to 10 min, depending
[32]
on the power rating of the motor.
[34]
[35]
Avoid generating external torque during AMA.
[36]
[55]
If one of the settings in parameter group 1-2* is changed,
[56]
par. 1-30 to par. 1-39, the advanced motor parameters, will
[57]
return to default setting.

value is determined from the motor database.
1-35 Main Reactance (Xh) may be adjusted to
