Select the Potentiometer for Speed Command - the motor speed may be controlled from the following sources:

•Potentiometer on front panel keypad

•Control terminals

•Remote panel

Then follow the steps in the table below to select the potentiometer for the speed command (the table resumes action from the end of the previous table).

Select the Keypad for the RUN Command - the RUN command causes the inverter to accelerate the motor to the selected speed. You can program the inverter to respond to either the control terminal signal or the keypad RUN key.

Follow the steps in the table below to select the front panel RUN key as the source for the RUN Command (the table resumes action from the end of the previous table).

NOTE: When you press the STR key in the last step above (and the display = 02), the Run Enable LED above the RUN switch on the keypad will turn ON. This is normal, and does not mean the motor is trying to run. It means that the RUN key is now enabled. DO NOT press the RUN key at this time — finish out the programming exercise first.

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.
