1.5 OPERATION
1.5.1 Pre-operation Check
Check the following items after completion of installation and wiring:
(1) No fault in wiring.
Never connect AC main circuit power supply to output terminal (U, V, W)
(2) No short circuit because of wiring contamination (dust, oil, etc.)
(3) Screws and terminals are tightened. Wiring is proper.
Load status is good.
(4) For safe operation, the motor must be able to operate alone by separating it from the coupling of belt,
which connects the motor and the machine. Pay close attention when the motor is operated with the
machine directly connected.
(5) Wiring is not grounded.
(6) Run command is not input.
When the forward/reverse run command is input in the operation mode (factory setting for the model
with blank cover) from the control circuit terminal, the motor is activated automatically after the
main circuit power supply is turned on. Turn on the inverter power supply after checking that the run
command is not input.
