Inverter Mounting and Installation
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 specifi-
cations 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 "Keypad Navigational Map" on page 20 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.
