2. Pick up a switch between STF and SD or STR and SD.
3. Pick up a potentiometer among 2-5-10 or provide 0~5V DC between 2 and 5.
4. Adjust the potentiometer to a minimum value between or 0 and 5V DC (under 1V).
5. There is a forward rotation if STF is on, or a reverse rotation if STR on. Turn off STF or STR for
the motor to decelerate till it stops.
6. Make sure of the following aspects:
1) Motor rotation direction is correct.
2) A smooth motor rotation (no abnormal noise or vibration).
3) A smooth acceleration and deceleration.
Set up the DU06 operation panel as follows:
1. Properly connect the DU06 operation panel to the inverter.
2. Change the operation mode to the PU mode after turning on the power, and the screen will display
50/60Hz.
3. Press to set the target frequency to 5Hz.
4. Press
FWD
for forward rotation; press
REV
for reverse rotation; press
STOP
RESET
for motor decelerate till it
stops.
5. Examining the following aspects:
1) A correct motor rotation direction.
2) A smooth motor rotation (no abnormal noise or vibration).
3) A smooth acceleration and deceleration.
If there is no abnormal condition, increase the frequency to test the motor in a continuous running
state. Start the operation if no abnormal condition is found from the above commissioning.
Note: If the inverter or the motor runs anomalous, stop the operation immediately. Check the causes according to
the Fault Diagnosis. Though the inverter is stopped, power terminal (R/L1-S/L2-T/L3) of the main circuit is
still connected. In this case electric shock may occur when touching the output terminals
(U/T1-V/T2-W/T3) of the inverter. Because the filter capacitor has recharging voltage and a complete
discharging takes some times, electric shock may happen even if the major loop power has been shut off. So
after shutting off the major loop power, use a DC voltage meter to test the intermediate DC loop. Confirm
the safe voltage value before handling the circuit inside inverter
