Start-Up 4 - 9
Flux Vector Start-Up
1-8. See Drive Start-Up Procedures on Page 4-5.
9. Apply input power to the Drive.
10. Set the control method of the Drive to Flux Vector 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 “3: Flux Vector”. Ensure the DATA/ENTER key is pressed to enter the selection
in the Drive. “Entry Accepted” will briefly appear.
11. Set the PG Pulses/Rev of the PG (Encoder) to the correct value. In the Quick Setting menu, go to parameter F1-01
“PG Pulses/Rev”. Use the UP, DOWN, and RESET keys and the DATA/ENTER key to set the encoder PPR.
12. Display motor speed monitor U1-05 “Motor Speed” in the Operation menu.
13. Rotate the motor shaft by hand in the forward direction of the machine. A low positive speed should be displayed
(PG-B2, PG-X2, PG-W2). As the shaft is turned in reverse, a low negative speed should be displayed. If the speed
doesn’t change when the motor shaft is rotated, check the encoder wiring and connections. If the polarity is wrong,
swap A+ and A- wires (terminals 4 and 5 on the PG-X2).
14. 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.
15. Display monitor U1-01 “Frequency Ref” in the Operation menu.
16. 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. U1-01 “Frequency Ref” displays 6.00Hz on the Digital Operator. The frequency reference for this
operation comes from parameter d1-17 “Jog Reference” with a 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. The encoder polarity may need to be reversed.
17. Proceed to the Auto-Tuning section.
THE NEXT KEY-PRESS WILL CAUSE THE MOTOR TO ROTATE.
TAKE APPROPRIATE PRECAUTIONS.
