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.)

		Action	Display			Func./Parameter
(Starting point)
				b012	Level of electronic thermal setting
	FUNC
Press the		key.		b- - -	“B” Group selected
Press the		key two times.			“H” Group selected
	1			H- - -
Press the	FUNC	key.			First “H” Group parameter
				H003
Press the	1	key once		H004	Motor poles parameter
					2	= 2 poles
	FUNC				4	= 4 poles (default)
Press the		key.		4
					6	= 6 poles
					8	= 8 poles
					Set to your motor specs (your display
Press the	1	or 2 key as needed.		4
					may be different)
					Store parameter, returns to “H”
Press the	STR	key.		H004
					Group list

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 Map on page 2-26to 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.
