*
[50 - 1000
V]
Enter the nominal motor voltage
according to the motor nameplate data.
The default value corresponds to the
nominal rated output of the unit.
This parameter cannot be adjusted while
the motor is running.
1-23 Motor Frequency

*
[20 -
400 Hz]
Select the motor frequency value from the
motor nameplate data.For 87 Hz operation
with 230/400 V motors, set the nameplate
data for 230V/50Hz. Adapt
and
to the 87Hz application.
NOTE
This parameter cannot be adjusted while the motor is
running.
1-24 Motor Current
Range:
Function:

*
[0.01 - 26.0
A]
Enter the nominal motor current value
from the motor nameplate data. This
data is used for calculating motor
torque, motor thermal protection etc.
NOTE
This parameter cannot be adjusted while the motor is
running.
1-25 Motor Nominal Speed
Range:
Function:

*
[100.0 -
60000.0 RPM]
Enter the nominal motor speed
value from the motor nameplate
data. This data is used for
calculating automatic motor
compensations.
NOTE
This parameter cannot be adjusted while the motor is
running.
1-29 Automatic Motor Adaption (AMA)

Complete
AMA
Performs AMA of the stator resistance R
S
, the
stator leakage reactance X
1
, the rotor leakage
reactance X
2
and the main reactance X
h
.
NOTE
Please note that terminal 27 Digital Input
(
5-12 Terminal 27 Digital Input
) has coast
inverse as default setting. This means that
AMA can not be performed if there is no
24V to terminal 27, so please connect
terminal 12 to terminal 27.
[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.
Activate the AMA function by pressing [Hand on] after
selecting [1] or [2]. 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 can not be performed on a motor with a
bigger power rating than the frequency converter,
e.g. when a 5.5kW motor is connected to a 4kW
frequency converter.
NOTE
Avoid generating external torque during AMA.
