1-23 Motor Frequency
Range:
50. Hz* [20 - 1000 Hz]
NOTE!
This parameter cannot be adjusted while the motor is running.
1-24 Motor Current
Range:
7.20 A* [0.10 - 10000.00 A]
NOTE!
This parameter cannot be adjusted while the motor is running.
1-25 Motor Nominal Speed
Range:
1420. RPM* [100 - 60000 RPM]
NOTE!
This parameter cannot be changed while the motor is running.
1-29 Automatic Motor Adaptation (AMA)
Option:
[0] * Off
[1] Enable complete AMA
[2] Enable reduced AMA
Activate the AMA function by pressing [Hand on] after selecting [1] or [2]. See also the section
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.
Function:
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
Maximum Reference
and par.3-03
Function:
Enter the nominal motor current value from the motor nameplate data. This data is used for cal-
culating motor torque, motor thermal protection, etc.
Function:
Enter the nominal motor speed value from the motor nameplate data. This data is used for calcu-
lating automatic motor compensations.
Function:
The AMA function optimizes dynamic motor performance by automatically optimizing the advanced
motor parameters par. 1-30 Stator Resistance (Rs)
