Function:
[Application Enter the nominal motor voltage
dependant] according to the motor nameplate
data. The default value
corresponds to the nominal rated
output of the unit.
Function:
Min - Max motor frequency: 20 - 1000 Hz.
Select the motor frequency value from the
motor nameplate data. If a value different
from 50 Hz or 60 Hz is selected, it is necessary
to adapt the load independent settings in
par. 1-50 Motor Magnetisation at Zero Speed to
par. 1-53 Model Shift Frequency. For 87 Hz
operation with 230/400 V motors, set the
nameplate data for 230 V/50 Hz. Adapt
par. 4-13 Motor Speed High Limit [RPM] and
par. 3-03 Maximum Reference to the 87 Hz
application.
Function:
[Application Enter the nominal motor current
dependant] value from the motor nameplate
data. The data are used for
calculating torque, motor protec-
tion etc.
Function:
[10 - 60000 Enter the nominal motor speed value
RPM] from the motor nameplate data. The
data are used for calculating motor
compensations.
NOTE
Motor speed must always be
lower than synchronous
speed.
Function:
[0.1 - Enter the value from the motor
nameplate data. The default value
corresponds to the nominal rated
output. This parameter is available
when par. 1-10 Motor Construction is
set to PM, non salient SPM [1], i.e. the
parameter is valid for PM and non-
salient SPM motors only.

NOTE
It is important to set motor par. 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.

Function:
The AMA function optimises dynamic motor
performance by automatically optimising the
advanced motor parameters (par. 1-30 Stator
Resistance (Rs) to par. 1-35 Main Reactance (Xh))
at motor standstill.
Activate the AMA function by pressing [Hand on]
after selecting [1] or [2]. See also the section
Automatic Motor Adaptation in the Design Guide.
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.
This parameter cannot be adjusted while the
motor is running.

T4/T5 E and F Frames, T7 D, E and F Frames will
only run a Reduced AMA when the complete
AMA is selected. It is recommended to obtain
the Advanced Motor Data from the motor
manufacturer to enter into par. 1-31 through
1-36 for best performance.
