V/F Start-Up

9.

Apply input power to the Drive.

10. Set the control method of the Drive to V/F Control by pressing the MENU key twice for the Quick Setting menu.

Press the ENTER key to display A1-02 “Control Method”. Use the UP and DOWN keys and the DATA/ENTER
key to set this parameter to “0: V/F Control”. Ensure the DATA/ENTER key is pressed to enter the selection in the
Drive. “Entry Accepted” will briefly appear.

11. Set the Drive input voltage measured in Step 1. In the Quick Setting menu, go to parameter E1-01 “Input Voltage”.

This parameter sets the nominal input voltage the Drive will receive.

12. Select an appropriate V/F pattern per the application. Go to parameter E1-03 “V/F Selection” and set this parameter

per the application. A standard V/F pattern for a 60Hz motor is “1: 60Hz Saturation”.

13. Set the Drive to Local control. Press the MENU key once to display the Operation menu. Then, press DATA/

ENTER to display “Frequency Reference”. Press the LOCAL/REMOTE key once. This puts the Drive in the Local
Mode, allowing run/stop and speed commands by the Digital Operator. The AUTO SEQ and AUTO REF indicators
turn off, and the FWD light turns on.

14. Check the motor rotation. Press and hold the JOG key to check motor rotation. The RUN light turns on and the

STOP light is off. “Frequency Ref” (U1-01) now displays 6.00Hz on the Digital Operator. The frequency reference
for this operation comes from parameter d1-17 “Jog Reference” with factory default setting of 6.00Hz. The motor
should ramp up to speed. If the motor rotation is incorrect, swap any two motor leads (U/T1, V/T2, W/T3) on the
Drive terminal, and repeat the motor rotation check.

15. Proceed to the Auto-Tuning section.
