Changing the value of this item from OFF to ON allows the detected phase ordering to be 
altered by moving the cursor to the required position and scrolling UP/DOWN to select the 
desired value. Set the phase ordering according to installation. Capital and small letters 
refer to voltage and current, respectively. ‘+’ and ‘-‘ signs refer to direction of the CT 
output.  
 
It is also possible to fine-tune the algorithm by altering the value of the load threshold. A 
higher value will tend to favor the unloaded solutions and vice versa. The load threshold 
can be found under: 
MENU: Edit Settings / Alarm Thresholds / Load threshold

Running LEARN and IMPROVE 

3.4.5.1.

 

LEARN 

AMU should learn the motor under normal operating conditions. The LEARN period consists 
of a preset number of data acquisition cycles and periods of data analysis. Once the preset 
number of cycles has been reached, the acquired and preprocessed data are further 
processed to produce a database consisting of a collection of data sets representing the 
behavior of the motor system under the load conditions that the motor has met in practice. 
It is therefore important to have the motor operating under its expected running conditions 
during a learning period. In order to adequately cover the range of load conditions 
experienced by a motor system, a sufficient number of acquisition cycles or iterations is 
required.  

 

NOTE 

 

We recommend that you use somewhere between 15 

to 30 iterations for LEARN and 7-10 iterations for 

IMPROVE modes 

 

 

Since additional learning can also be performed if needed during the testing phase, a larger 
number of learning iterations is not generally required. The number of learning iterations 
can be set from the menu path: 
MENU: Edit Settings / Password / Run settings / Learn iterations. 

3.4.5.2.

 

IMPROVE 

Once the initial learning period is complete, the AMU unit will automatically try to improve 
its estimation of the motor characteristics by updating the database obtained during the 
learning mode.  The database is updated with different load and line conditions in the
