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.
NB!
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.
NB!
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.
NB!
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] * Off No function
[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 frequency converter 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 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
