1-23 Motor Frequency
Range:
Function:
50. Hz*
[20 - 1000 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 par.4-13
Motor Speed High Limit [RPM]
and par.3-03
Maximum Reference
to the 87 Hz application.
NOTE!
This parameter cannot be adjusted while the motor is running.
1-24 Motor Current
Range:
Function:
7.20 A*
[0.10 - 10000.00 A]
Enter the nominal motor current value from the motor nameplate data. This data is used for cal-
culating motor torque, motor thermal protection, etc.
NOTE!
This parameter cannot be adjusted while the motor is running.
1-25 Motor Nominal Speed
Range:
Function:
1420. RPM* [100 - 60000 RPM]
Enter the nominal motor speed value from the motor nameplate data. This data is used for calcu-
lating automatic motor compensations.
NOTE!
This parameter cannot be changed while the motor is running.
1-29 Automatic Motor Adaptation (AMA)
Option:
Function:
The AMA function optimizes dynamic motor performance by automatically optimizing the advanced
motor parameters par. 1-30
Stator Resistance (Rs)
to par. 1-35
Main Reactance (Xh)
) while the
motor is stationary.
[0] *

[1]
Enable complete AMA
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
.
[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.
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 adjustable frequency drive is ready for operation.
Note:
•
For the best adaptation of the adjustable frequency drive, run AMA on a cold motor.
