[ 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 230 V/50 Hz. Adapt
4-14 Motor Speed High Limit [Hz]
and
to the 87 Hz
application.
NOTE!
This parameter cannot be adjusted while the motor is
running.
1-24 Motor Current

*
[ 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 - 60000
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.
1-26 Motor Cont. Rated Torque
Range:

*
[0.1 - 10000.0
Nm]
This parameter is available only
when
1-10 Motor Construction
is
set to
[1] PM, non-salient SPM
.
NOTE!
Changing this parameter will affect settings of other
parameters.
1-29 Automatic Motor Adaption (AMA)
Option:
Function:
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor
to
while the motor is
stationary.
[0] Off
No function
[1] Enable
Complete
AMA
Performs AMA of the stator resistance R
S
, the
stator leakage reactance X
1
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 cannot be performed if there is
no 24 V to terminal 27; therefore,
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
adjustable frequency drive and the motor.
NOTE!
When
1-10 Motor Construction
is set to
[1] PM, non-salient
SPM
, the only option available is
[2] Enable Reduced AMA
.
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 adjustable frequency drive is ready for
operation.
NOTE!
•
For the best adaptation of the adjustable
frequency drive, 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 adjustable
frequency drive, e.g., when a 7.5 hp [5.5 kW]
motor is connected to a 5 hp [4 kW] adjustable
frequency drive.
NOTE!
Avoid generating external torque during AMA.
