1-23 Motor FrequencyRange: Function:50. Hz* [20 - 1000 Hz] Select the motor frequency value from the motor nameplate data.For 87 Hz operation with 230/400V motors, set the nameplate data for 230 V/50 Hz. Adapt par. 4-13Motor Speed High Limit[RPM] and par. 3-03Maximum Reference to the 87 Hz application.NB!This parameter cannot be adjusted while the motor is running.1-24 Motor CurrentRange: 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 SpeedRange: 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 advancedmotor parameters par. 1-30 StatorResistance (Rs) to par. 1-35 MainReactance (Xh)) while themotor is stationary.[0] * Off No function[1] Enable complete AMA performs AMA of the stator resistance RS, 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 Rs in the system only. Select this option if an LCfilter 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 sectionAutomatic 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 running8.
