Operation
BASIC OPERATION 41
4.4.3 Test run
Check cables and abnormalities before the test run. After power on, the inverter is in external mode.
1. After power on, make sure no alarm on built-in keypad, make sure indicator
and
is on.
2. Connect a switch between STF/SD and STR/SD.
3. Connect a potentiometer between 3-5-10 or provide 0~5V dc between 3 and 5.
4. Adjust potentiometer or 0~5V dc to a minimum value (under 1V).
5. If STF is on, forward rotation is activated. If STR is on, reverse rotation is activated. Turn off STF or STR to
decelerate the motor until it stops completely.
6. Check the following:
1). Whether the direction of motor rotation is correct.
2). Whether the rotation is smooth (check for noise and vibration).
3). Whether the acceleration / deceleration is smooth.
If there is an optional keypad, do the following:
1. Make sure the keypad is connected to the inverter properly.
2. Change the operation mode to PU mode after power on, check the target frequency is 50/60Hz.
3. Use the optional keypad to set the target frequency at about 5Hz.
4. Press
for forward rotation and
for reverse rotation. Press
to decelerate the motor until
it stops completely.
5. Check the following:
1) Whether the direction of motor rotation is correct.
2) Whether the rotation is smooth (check for noise and vibration).
3) Whether the acceleration / deceleration is smooth.
If it runs successfully, continue the test run by increasing the frequency and go through the above
procedure. After confirming that there are no abnormalities, it can be put into operation.
Note: If the operation of the inverter and motor is abnormal, stop the operation immediately and check the cause of the abnormality
according to “Troubleshooting”. After the inverter stops outputting, if the main circuit power terminals R/L1, S/L2, T/L3 are not
disconnected, if the inverter's output terminals U/T1, V/T2, W/T3 are touched, it may cause an electric shock.
In addition, even if
the main circuit power supply is turned off, due to the charging voltage on the filter capacitor, it will take a certain time for the
discharge to end. After the main circuit power supply is cut off, wait for 10 minutes and test the intermediate DC circuit voltage
with a voltmeter to confirm that it is below the safe voltage value before you can touch the internal circuit of the inverter.
