Primary Operation
4.3.3 Trial Run
Check the cables and make sure that there are no abnormalities before the operation. The inverter
will be at the external mode after turning on the power.
1. After turning on the power, make sure that Operation panel shown no fault, the indicating lamp of
and
are all lit up when the keyboard panel is not chosen.
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
.
