FC 300 Instruction Manual
How to Program
NOTE
If a delta connection is used, select
the rated motor frequency for the
delta connection.
1-24 Motor Current
Range:
Motor type depende nt.
Function:
Enter the nominal motor current value from
the motor nameplate data. The data are
used for calculating torque, motor protection,
etc. This parameter cannot be adjusted
while the motor is running.
1-25 Motor N om in al 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 comp lete AMA [1]
Enable reduced AMA [2]
Function:
The AMA functi on optimises dynamic motor
performance by automatically optimising the
advanced motor parameters (par. 1-30 to par.
1-35) while the m otor is stationary.

value is determined from the motor database.
Par. 1-35 Main Reactance (X

) may be adjusted
to obtain optimal start performa nce.
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.Afteranormal
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 ada ptation of the fre quency
converter, run AMA on a cold motor.
• AMA cannot be performed while the
motor is running.
• AMA cannot be performed on permane nt
magnet motors.
NOTE
It is important to set m o tor 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.
NOTE
Avoidgeneratingexternaltorque
during AMA.
NOTE
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 p arameter cann
ot
be adjusted while the motor is running.
3-02 Minimum Reference
Option:
-100000.000 - MaxReference (par. 3-03)

Function:
The Minimu m referen ce is the minimum
value obtained by the sum of all references.
