5.4.5 Automatic Energy Optimisation (AEO)NOTICEAEO is not relevant for PM motors.Automatic Energy Optimisation (AEO) is recommended for• Automatic compensation for oversized motors• Automatic compensation for slow system loadchange• Automatic compensation for seasonal changes• Automatic compensation for low motor loading• Reduced energy consumption• Reduced motor heating• Reduced motor noiseTo activate AEO, set parameter 1-03 Torque Characteristicsto [2] Auto Energy Optim. CT or [3] Auto Energy Optim. VT.5.4.6 Automatic Motor Adaptation (AMA)NOTICEAMA is not relevant for PM motors.Automatic motor adaptation (AMA) is a procedure thatoptimises compatibility between the frequency converterand the motor.• The frequency converter builds a mathematicalmodel of the motor for regulating output motorcurrent. The procedure also tests the input phasebalance of electrical power. It compares themotor characteristics with the data entered inparameters 1-20 to 1-25 .• The motor shaft does not turn and no harm isdone to the motor while running the AMA.• Some motors may be unable to run the completeversion of the test. In that case, select [2] Enablereduced AMA.• If an output filter is connected to the motor,select Enable reduced AMA.• If warnings or alarms occur, see 7.4 List ofWarnings and Alarms.• Run this procedure on a cold motor for bestresults.To run AMA1. Press [Main Menu] to access parameters.2. Scroll to parameter group 1-** Load and Motorand press [OK].3. Scroll to parameter group 1-2* Motor Data andpress [OK].4. Scroll to 1-29 Automatic Motor Adaptation (AMA)and press [OK].5. Select [1] Enable complete AMA and press [OK].6. Follow on-screen instructions.7. The test runs automatically and indicate when itis complete.5.5 Checking Motor RotationWARNINGMOTOR STARTFailure to ensure that the motor, system, and anyattached equipment are ready for start can result inpersonal injury or equipment damage. Before start,• Ensure equipment is safe to operate under anycondition.• Ensure that the motor, system, and anyattached equipment are ready for start.NOTICERisk of damage to pumps/compressors caused by motorrunning in wrong direction. Before running thefrequency converter, check the motor rotation.The motor runs briefly at 5 Hz or the minimum frequencyset in 4-12 Motor Speed Low Limit [Hz].1. Press [Main Menu].2. Scroll to 1-28 Motor Rotation Check and press[OK].3. Scroll to [1] Enable.The following text appears: Note! Motor may run in wrongdirection.4. Press [OK].5. Follow the on-screen instructions.NOTICETo change the direction of rotation, remove power tothe frequency converter and wait for power to discharge.Reverse the connection of any 2 of the 3 motor wires onthe motor or frequency converter side of the connection.Commissioning VLT® AQUA Drive FC 202 Operating Instructions26 MG20MA02 - Rev. 2013-10-2955
