3.12.3 Trial Run
Confirm cables and no abnormalities before the operation you can try running. After power on, the
inverter is in the external mode.
1. After power on, ensure the indicating lamp of power
is lit.
2. Please pick a switch between STF and SD or STR and SD.
3. Please pick a potentiometer among 2-5-10 or provide 0 ~ 5V dc between 2 and 5.
4. Please adjust potentiometer or 0 ~ 5V dc a minimum value (under 1V).
5. If STF on, forward rotation; if STR on, reverse rotation; Turn off STF or STR, and the motor will
decelerate till it stops.
6. Ensure the following several aspects:
1). Motor rotation direction is correct or not.
2). Motor rotating smoothly (whether there is no abnormal noise and vibration).
3). Whether or not smooth for acceleration/deceleration.
If there is operation panel, commissioning as follows:
1. Operation panel connected to inverter properly.
2. Change the operation mode to PU mode after power on, and the screen will display 50/60Hz.
3. Press
button to set the target frequency is about 5Hz.
4. Press
FWD
, forward rotation; press
REV
, reverse rotation; press
STOP
RESET
then the motor will decelerate till
it stops.
