After using the keypad for parameter editing, it’s a good idea to switch the inverter from Program Mode to Monitor Mode. The PRG LED will be OFF, and the Hertz or Ampere LED indicates the display units.

For the powerup test, monitor the motor speed	RUN	STOP	RUN

indirectly by viewing the inverter’s output frequency.	FUNC	1	2	STR
The output frequency must not be confused with base
frequency (50/60 Hz) of the motor, or the carrier

frequency (switching frequency of the inverter, in the kHz range). The monitoring functions are in the “D” list, located near the top left of the “Keypad Navigation Map”on page 2-26.

Output frequency (speed) monitor – Resuming keypad operation from the previous table, follow the steps below. Or instead, you can simply power cycle the inverter, which automatically sets the display to D001 (output frequency value).

When the inverter displays a monitor value, the PRG LED is OFF. This confirms the inverter is not in programming mode, even while you are selecting the particular monitoring parameter. The display shows the current speed (is zero at this point). The Hz LED will be ON, indicating the display units. For current, the Amperes LED will be ON.

Running the Motor

If you have programmed all the parameters up to this point, you’re ready to run the motor! First, review this checklist:

1.Verify the power LED is ON. If not, check the power connections.

2.Verify the Potentiometer Enable LED is ON. If it is OFF, check the A001 setting.

3.Verify the Run Key Enable LED is ON. If it is OFF, check the A002 setting.

4.Verify the PRG LED is OFF. If it is ON, review the instructions above.

5.Make sure the motor is disconnected from any mechanical load.

6.Turn the potentiometer to the minimum position (completely counter clock-wise).

7.Now, press the RUN key on the keypad. The RUN LED will turn ON.

8.Slowly increase the potentiometer setting in clockwise fashion. The motor should start turning.

9.Press the STOP key to stop the motor rotation.
