Set the Number of Motor Poles – The motor’s internal winding arrangement determines
its number of magnetic poles. The specification label on the motor usually indicates the
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 (H004).
Follow the steps in the table below to verify the motor poles setting and change 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!

IP: If you became lost during any of these steps, first observe the state of the PRG LED.
Then study the “Keypad Navigation Map on page 2-26 to determine the current state of
the keypad controls and display. As long as you do not press the STR key, no parameter
will be changed by keypad entry errors. Note that power cycling the inverter causes it to
power up Monitor Mode, displaying the value for D001 (output frequency).
The next section will show you how to monitor a particular parameter from the display.
Then you will be ready to run the motor.
