Configure the Inverter for the Number of Motor Poles- The number of magnetic poles of a 
motor is determined by the motor’s internal winding arrangement. The specifications label on 
the motor usually indicates its number of poles. For proper operation, verify the parameter 
setting matches the motor poles. Many industrial motors have four poles, corresponding to the 
default setting in the inverter.

Follow the steps in the table below to verify the motor poles setting and change it if necessary 
(the table resumes action from the end of the previous table.)

This step concludes the parameter setups for the inverter. You are almost ready to run the motor 
for the first time!

TIP: If you became lost during any of these steps, first observe the state of the PRG LED. Then 
study the 

 to determine the current state of the 

keypad controls and display. As long as you do not press the STR key, no parameters will be 
changed by keypad entry errors. Note that power cycling the inverter will not cause it to reset to 
a particular programming state.

The next section will show you how to monitor a particular parameter from the display. Then 
you will be ready to run the motor.
