Set The Number Of Motor Poles - Omron 3G3MX2 User Manual

Using the Front Panel Keypad
!Tip
5. Set the Number of Motor Poles – The motor's internal winding arrange-
ment 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 ().
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!
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 60 to determine
the current state of the keypad controls and display. As long as you do not
press the key, no parameter will be changed by keypad entry errors.
Note that power cycling the inverter causes it to power up Monitor Mode, dis-
playing the value for  (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.
