Primary operation
5.
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 no abnormal condition, increasing frequency to test run continue, through the above
commissioning, without any abnormal situation, can be put into operation.
Note: If inverter and motor running anomalies, shall be stopped working immediately, and
according
to the "fault
diagnosis," check anomalies causes. After inverter stop output, but the power terminal (R/S/T) of main
circuit is not disconnected, if you touching the output terminals (U/V/W) of inverter, may occur shock.
Otherwise, even cut off major loop power, because the filter capacitor has recharging voltage, discharge end
need some time, After cut off major loop power, wait for the indicating lamp of power burn out, and use a dc
voltage meter to test intermediate dc loop, confirm below safe voltage value, then you can contact the circuit
which inside inverter
