Using the Front Panel Keypad
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 specifica-
tions 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, which is 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 keypad navigation on page 21 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.
