How to Programme
1-25 Motor Nominal Speed
Range:
100 - 60000 RPM
*
RPM
Function:
Enter the nominal motor speed value from the
motor nameplate data. The data are used for
calculating motor compensations. This parameter
cannot be adjusted while the motor is running.

1-29 Automatic Motor Adaptation (AMA)
Option:
*
OFF
[0]
Enable complete AMA
[1]
Enable reduced AMA
[2]
Function:
The AMA function optimises dynamic motor
performance by automatically optimising the
advanced motor parameters (par. 1-30 to par.
1-35) while the motor is stationary.
Select the type of AMA.
Enable complete AMA
[1]
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
. Select this option if an LC filter is
used between the drive and the motor.
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.
Par. 1-35
Main Reactance (X
h
)
may be adjusted
to obtain optimal start performance.
Select
Reduced AMA
[2] performs a reduced AMA
of the stator resistance R
s
in the system only.
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.
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.
NB!:
It is important to set motor par. 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.
NB!:
Avoid generating external torque
during AMA.
NB!:
If one of the settings in par. 1-2* Motor
Data is changed, par. 1-30 to 1-39,
the advanced motor parameters, will
return to default setting. This parameter cannot
be adjusted while the motor is running.
